It includes a cylinder insertion step of inserting the cylinder into the cylinder, a removal step of removing the generated temperature difference, and a plunger placement step of arranging a cylindrical plunger reciprocally in the pressurizing chamber of the inner cylinder.
　また、上記製造方法において、温度差発生工程は、外側シリンダを加熱する加熱工程を含み、シリンダ挿入工程は、内側シリンダの外径よりも内径が長くなっている状態の外側シリンダに、内側シリンダを挿入し、除去工程は、外側シリンダを冷却する冷却工程を含むこととしてもよい。 Further, in the above manufacturing method, the temperature difference generation step includes a heating step of heating the outer cylinder, and the cylinder insertion step is to attach the inner cylinder to the outer cylinder in a state where the inner diameter is longer than the outer diameter of the inner cylinder. The insertion and removal steps may include a cooling step of cooling the outer cylinder.
　また、上記製造方法において、温度差発生工程は、内側シリンダを冷却する冷却工程を含み、シリンダ挿入工程は、外側シリンダの内径よりも外径が短くなっている状態の内側シリンダを、外側シリンダに挿入し、除去工程は、内側シリンダを加熱する加熱工程を含むこととしてもよい。 Further, in the above manufacturing method, the temperature difference generation step includes a cooling step of cooling the inner cylinder, and the cylinder insertion step changes the inner cylinder into the outer cylinder in a state where the outer diameter is shorter than the inner diameter of the outer cylinder.

　また、上記製造方法において、温度差発生工程は、外側シリンダを加熱する加熱工程と、内側シリンダを冷却する冷却工程とを含み、シリンダ挿入工程は、内側シリンダの外径よりも内径が長くなっている状態の外側シリンダに、内側シリンダを挿入し、除去工程は、外側シリンダを冷却する冷却工程と、内側シリンダを加熱する加熱工程とを含むこととしてもよい。 Further, in the above manufacturing method, the temperature difference generation step includes a heating step of heating the outer cylinder and a cooling step of cooling the inner cylinder, and the cylinder insertion step has an inner diameter longer than the outer diameter of the inner cylinder.

　また、上記課題を解決するために、本開示の一態様に係るプランジャポンプは、試料が内部を通過することで、試料を微粒化する微粒化流路を有する微粒化装置に接続され、微粒化装置の内部に試料を高圧で供給するプランジャポンプであって、外側シリンダと、外側シリンダの内側に挿入され、内部に円筒状の加圧室が形成される内側シリンダと、内側シリンダの加圧室に円筒状のプランジャを往復動可能に配置されるプランジャと、を備え、内側シリンダは、外側シリンダにより圧迫されるように構成されている。 Further, in order to solve the above problems, the plunger pump according to one aspect of the present disclosure is connected to an atomizing device having an atomizing flow path for atomizing the sample by passing the sample inside, and atomizing the sample.

　本開示のプランジャポンプの製造方法は、外側シリンダと内側シリンダとからなるシリンダを有するプランジャポンプを製造するものであり、外側シリンダまたは内側シリンダに対して常温状態から異なる温度とすることで、サイズを変更し、その間に、外側シリンダに内側シリンダを挿入する。したがって、常温状態に戻ると、外側シリンダが内側シリンダに対して常時外圧を加えている状態のシリンダを構成することができるので、そのシリンダ内部を通過する高圧の試料からの内圧と対抗させることができ、プランジャを構成するシリンダの金属疲労を抑制することができる。 The method for manufacturing a plunger pump of the present disclosure is to manufacture a plunger pump having a cylinder composed of an outer cylinder and an inner cylinder, and the size of the outer cylinder or the inner cylinder is changed from the normal temperature state to a different temperature.

　本開示の一態様に係るプランジャポンプの製造方法およびプランジャポンプについて、図面を参照しながら詳細に説明する。 The manufacturing method of the plunger pump and the plunger pump according to one aspect of the present disclosure will be described in detail with reference to the drawings.
　図１は、プランジャポンプが利用される微粒化装置ユニット１の構成例を模式的に示す概念図である。図１に示すように、微粒化装置ユニット１は、試料を微粒化して均一化させるホモジナイザーユニットである。微粒化装置ユニット１は、微粒化装置１０、供給容器３０、取出容器３１、およびこれらを接続する配管４０、４１、４２、４３を備えている。 FIG. 1 is a conceptual diagram schematically showing a configuration example of a atomizing device unit 1 in which a plunger pump is used. As shown in FIG. 1, the atomizing device unit 1 is a homogenizer unit that atomizes and homogenizes a sample. The atomizing device unit 1 includes an atomizing device 10, a supply container 30, a take-out container 31, and pipes 40, 41, 42, 43 connecting these.
　微粒化装置１０は、試料が内部を通過することで、該試料を微粒化する微粒化流路を有している。微粒化装置１０は、オリフィスホモジナイザあるいは単にオリフィスと呼称されることもある。ここで、微粒化装置１０の構造について、図２および図３を用いて詳述する。 The atomizing device 10 has an atomizing flow path for atomizing the sample by passing the sample through the inside. The atomizing device 10 is sometimes referred to as an orifice homogenizer or simply an orifice. Here, the structure of the atomizing device 10 will be described in detail with reference to FIGS. 2 and 3.
　図２は微粒化装置１０の縦断面図であり、図２のＡ－Ａ線における断面図が図３（ａ）であり、図２のＢ－Ｂ線における断面図が図３（ｂ）であり、図２のＣ－Ｃ線における断面図が図３（ｃ）である。 FIG. 2 is a vertical sectional view of the atomizing device 10, FIG. 2A is a sectional view taken along the line AA, and FIG. 2 is a sectional view taken along the line BB of FIG. 2 is FIG. 3B. Yes, the cross-sectional view taken along the line CC of FIG. 2 is FIG. 3 (c).
　微粒化装置１０は、第１ブロック２１と第２ブロック２２、そして第１ブロック２１と第２ブロック２２の間に介装される第３ブロック２３により形成される。第１ブロック２１において、複数の流路部１１、１２が形成される（図２および図３（ａ）参照）。また、第２ブロック２２においても、複数の流路部１８、１９が形成される。 The atomizing device 10 is formed by a first block 21, a second block 22, and a third block 23 interposed between the first block 21 and the second block 22. In the first block 21, a plurality of flow path portions 11 and 12 are formed (see FIGS. 2 and 3 (a)). Further, also in the second block 22, a plurality of flow path portions 18 and 19 are formed.
　第１ブロック２１と第３ブロック２３との接合面に意図的に第１空隙部１４が形成される。この第１空隙部１４が複数の流路部１１、１２を単一に集合させる集合部１３となる（図２および図３（ｂ）参照）。集合部１３（第１空隙部１４）のうち、流路方向における流路部１１、１２と反対側は第３ブロック２３となり、第３ブロック２３内にオリフィス流路部１５が形成される（図２および図３（ｃ）参照）。 The first gap portion 14 is intentionally formed on the joint surface between the first block 21 and the third block 23. The first gap portion 14 serves as an gathering portion 13 for singing a plurality of flow path portions 11 and 12 (see FIGS. 2 and 3 (b)). Of the collecting portion 13 (first gap portion 14), the side opposite to the flow path portions 11 and 12 in the flow path direction becomes the third block 23, and the orifice flow path portion 15 is formed in the third block 23 (FIG. 2 and FIG. 3 (c)).
　オリフィス流路部１５の下流側においても、第３ブロック２３と第２ブロック２２との接合面にも意図的に第２空隙部１６が形成される。この第２空隙部１６がオリフィス流路部１５を分岐させて複数の流路部１８、１９と接続する分岐部１７となる。すなわち、微粒化流路は、流路部１１、１２、オリフィス流路部１５、および流路部１８、１９により構成されている。 A second gap 16 is intentionally formed on the joint surface between the third block 23 and the second block 22 also on the downstream side of the orifice flow path portion 15. The second gap 16 serves as a branch 17 that branches the orifice flow path 15 and connects to the plurality of flow paths 18 and 19. That is, the atomized flow path is composed of the flow path portions 11 and 12, the orifice flow path portion 15, and the flow path portions 18 and 19.
　流路部１１、１２および流路部１８、１９の内直径（Ｄ１）は相互に同一であり、オリフィス流路部１５の内直径（Ｄ２）よりも大きく形成される。具体的には、内直径（Ｄ１）は、内直径（Ｄ２）の５ないし７倍である。また、第１空隙部１４の距離（Ｄ３）は内直径（Ｄ１）と同等に規定される。従って、オリフィス流路部１５は小径流路部である。　　　 The inner diameters (D1) of the flow paths 11 and 12 and the flow paths 18 and 19 are the same as each other, and are formed larger than the inner diameter (D2) of the orifice flow path 15. Specifically, the inner diameter (D1) is 5 to 7 times the inner diameter (D2). Further, the distance (D3) of the first gap portion 14 is defined in the same manner as the inner diameter (D1). Therefore, the orifice flow path portion 15 is a small diameter flow path portion.
　次に、微粒化装置１０を用いた際の作用を説明する。被処理物を有機溶媒中に分散させた試料は、流路部１１、１２を経由して集合部１３（第１空隙部１４）に侵入する。ここで、オリフィス流路部１５は流路部１１、１２よりも狭小であるため、試料の流量は低下する。そして、試料（圧送流体）の圧力変化が生じ、それぞれの流路部１１、１２から流入した試料は集合部１３において衝突する。このときの試料中の被処理物同士は衝突時のエネルギーにより破砕される。このように、試料が流路部１１、１２からオリフィス流路部１５へ流動するごとに、試料中の被処理物同士の衝突が進み、結果として試料は粉砕される。 Next, the action when the atomizing device 10 is used will be described. The sample in which the object to be treated is dispersed in the organic solvent penetrates into the collecting portion 13 (first void portion 14) via the flow path portions 11 and 12. Here, since the orifice flow path portion 15 is narrower than the flow path portions 11 and 12, the flow rate of the sample decreases. Then, a pressure change of the sample (pressure feeding fluid) occurs, and the samples flowing in from the respective flow path portions 11 and 12 collide with each other in the collecting portion 13. The objects to be processed in the sample at this time are crushed by the energy at the time of collision. In this way, each time the sample flows from the flow path portions 11 and 12 to the orifice flow path portion 15, collisions between the objects to be processed in the sample proceed, and as a result, the sample is crushed.
　図示の流路部１１、１２および流路部１８、１９それぞれは、ともに２つずつ形成されているが、流路部１１、１２および流路部１８、１９の形成数は、試料が流れればよいので、１以上あればよい。ただし、試料中の被処理物の衝突を促すため、流路部１１、１２および流路部１８、１９それぞれの形成数は、ともに２以上であることがさらに望ましい。 Two of each of the flow paths 11 and 12 and the flow paths 18 and 19 shown in the figure are formed, but the number of the flow paths 11 and 12 and the flow paths 18 and 19 formed is such that the sample flows. Since it is sufficient, one or more is sufficient. However, in order to promote collision of the object to be processed in the sample, it is more desirable that the number of each of the flow paths 11 and 12 and the flow paths 18 and 19 formed is 2 or more.
　図１に戻って、供給容器３０は、微粒化流路に試料を供給する。供給容器３０は、微粒化経路の最も上流側に設けられており、図示の通り、弁７１に配管４０を介して接続されている。供給容器３０には、微粒化前の試料および図１の矢印に示されるように、微粒化経路を通過した後であって、まだ十分に微粒化されていない試料が充填される。なお、図１においては、取出容器３１から供給容器３０までの詳細な構成については、省略している。 Returning to FIG. 1, the supply container 30 supplies the sample to the atomization flow path. The supply container 30 is provided on the most upstream side of the atomization path, and is connected to the valve 71 via a pipe 40 as shown in the figure. The supply container 30 is filled with a sample before atomization and, as shown by the arrow in FIG. 1, a sample that has passed through the atomization path and has not yet been sufficiently atomized. In FIG. 1, the detailed configuration from the take-out container 31 to the supply container 30 is omitted.
　取出容器３１は、試料が完全に均一化されたのちに、試料を取り出すための容器である。 The take-out container 31 is a container for taking out the sample after the sample is completely homogenized.
　なお、微粒化装置ユニット１は、取出容器３１を備えずに（備えていてもよい）、配管４０からドレン８６等を介して、均一化された試料を取出すような構成であってもよい。図１では、取出容器３１およびドレン８６の両方を備えた構成を示している。 The atomizing device unit 1 may not be provided with the take-out container 31 (may be provided), and may be configured to take out a uniform sample from the pipe 40 via the drain 86 or the like. FIG. 1 shows a configuration including both a take-out container 31 and a drain 86.
　プランジャポンプ５１は、配管４０を介して弁７１並びに微粒化装置１０に接続されている。弁７１を開くことで、供給容器３０からの試料を、配管４１に流すことができ、弁７１を閉じることで、供給容器３０からの試料が配管４１に流出するのを防止するとともに、プランジャポンプ５１により押し出された試料が供給容器３０側に逆流するのを防止することができる。 The plunger pump 51 is connected to the valve 71 and the atomizing device 10 via the pipe 40. By opening the valve 71, the sample from the supply container 30 can flow into the pipe 41, and by closing the valve 71, the sample from the supply container 30 is prevented from flowing out to the pipe 41, and the plunger pump is pumped. It is possible to prevent the sample extruded by 51 from flowing back to the supply container 30 side.
　プランジャポンプ５１は、シリンダ５１Ａとプランジャ５１Ｂとにより構成されている。シリンダの内部をプランジャが往復動することで、シリンダの内部に試料を充填し、シリンダ内の試料を外部に送り出すことができる。図４は、プランジャポンプ５１の拡大イメージ図である。 The plunger pump 51 is composed of a cylinder 51A and a plunger 51B. By reciprocating the plunger inside the cylinder, the sample can be filled inside the cylinder and the sample inside the cylinder can be sent out. FIG. 4 is an enlarged image of the plunger pump 51.
　図４は、プランジャポンプの一部断面図であり、概念的なイメージ図である。図４には、プランジャポンプ５１の模式的な拡大図を示しているが、プランジャポンプ５２、５３についても同様の構造を有する。本実施の形態に係るプランジャポンプは、図４に示すように、シリンダ５１Ａが、内側シリンダ５１ａと外側シリンダ５１ｂとから成る。即ち、シリンダ５１Ａは二重構造を有する。シリンダ５１Ａにおいて、内側シリンダ５１ａは、外側シリンダ５１ｂにより、常時外圧が加えられる状態になるように構成されている。即ち、内側シリンダ５１ａには、外側シリンダ５１ｂ内に挿入されていない状態では、その外径が、外側シリンダ５１ｂの内径よりも大きい部材が用いられる。即ち、シリンダ５１Ａは、内側シリンダ５１ａが、外側シリンダ５１ｂにより圧迫されている状態で構成されている。なお、内側シリンダ５１ａは、外側シリンダ５１ｂよりも硬度の高い（硬い）材質であることが望ましく、一例として、ＳＵＳ６３０を用いることが考えられるが、この限りではない。また、外側シリンダ５１ｂは、内側シリンダ５１ａよりも若干柔らかい、弾性があって、内側シリンダ５１ａを締め付ける機能を持たせられる材質であることが望ましく、一例として、ＳＵＳ３１６等を用いることが考えられるが、その限りではない。 FIG. 4 is a partial cross-sectional view of the plunger pump and is a conceptual image diagram. FIG. 4 shows a schematic enlarged view of the plunger pump 51, but the plunger pumps 52 and 53 also have the same structure. In the plunger pump according to the present embodiment, as shown in FIG. 4, the cylinder 51A includes an inner cylinder 51a and an outer cylinder 51b. That is, the cylinder 51A has a double structure. In the cylinder 51A, the inner cylinder 51a is configured so that an external pressure is constantly applied by the outer cylinder 51b. That is, the inner cylinder 51a uses a member whose outer diameter is larger than the inner diameter of the outer cylinder 51b when it is not inserted into the outer cylinder 51b. That is, the cylinder 51A is configured in a state where the inner cylinder 51a is pressed by the outer cylinder 51b. The inner cylinder 51a is preferably made of a material having a higher hardness (harder) than the outer cylinder 51b, and SUS630 may be used as an example, but this is not the case. Further, it is desirable that the outer cylinder 51b is made of a material that is slightly softer than the inner cylinder 51a, has elasticity, and has a function of tightening the inner cylinder 51a, and SUS316 or the like may be used as an example. That is not the case.
　シリンダ５１Ａには、シリンダ５１Ａ内部を往復道するプランジャ５１Ｂが挿入、配置されている。プランジャ５１Ｂは、クランク機構の回転により、図４に示す矢印の方向に往復道する。これにより、プランジャポンプ５１は、試料を配管４１から吸引することができるとともに、試料を配管４１に押し出すことができる。 A plunger 51B that reciprocates inside the cylinder 51A is inserted and arranged in the cylinder 51A. The plunger 51B reciprocates in the direction of the arrow shown in FIG. 4 due to the rotation of the crank mechanism. As a result, the plunger pump 51 can suck the sample from the pipe 41 and push the sample into the pipe 41.
　微粒化装置１０には、更に、配管４３を介して、弁７３並びに弁７５が接続されている。弁７３を開くことで、微粒化装置１０からの試料を、配管４３に流すことができ、弁７３を閉じることで、微粒化装置１０からの試料が配管４３に流出するのを防止することができる。また、弁７５を開くことで、微粒化装置１０からの試料を、ドレン８６に流すことができ、弁７５を閉じることで微粒化装置１０からの試料がドレン８６側に流出するのを防止することができる。 A valve 73 and a valve 75 are further connected to the atomizing device 10 via a pipe 43. By opening the valve 73, the sample from the atomizing device 10 can flow into the pipe 43, and by closing the valve 73, the sample from the atomizing device 10 can be prevented from flowing out to the pipe 43. it can. Further, by opening the valve 75, the sample from the atomizing device 10 can flow to the drain 86, and by closing the valve 75, the sample from the atomizing device 10 is prevented from flowing out to the drain 86 side. be able to.
　弁７３には、配管４３が接続され、配管４３は、取出容器３１に接続されている。配管４３には、熱交換器８０が設けられていてもよく、微粒化装置１０による微粒化工程によって、試料が熱をもった場合に、その熱を除去する機能を果たす。 A pipe 43 is connected to the valve 73, and the pipe 43 is connected to the take-out container 31. The pipe 43 may be provided with a heat exchanger 80, which functions to remove the heat when the sample has heat by the atomizing step by the atomizing device 10.
　微粒化装置ユニット１はまた、プランジャポンプ５１や各弁７１、７３、７５等の開閉を制御する制御部（図示せず）を備えてもよい。制御部は、微粒化装置ユニット１におい、試料が、微粒化経路をループして、目標とする粒度まで微粒化経路を流動するように、プランジャポンプ５１および各弁７１、７３、７５の開閉を制御する。 The atomizing device unit 1 may also include a control unit (not shown) that controls the opening and closing of the plunger pump 51 and the valves 71, 73, 75 and the like. The control unit opens and closes the plunger pump 51 and the valves 71, 73, and 75 in the atomizing device unit 1 so that the sample loops through the atomizing path and flows through the atomizing path to the target particle size. Control.
　以上のような構成を有する微粒化装置ユニット１において、試料を微粒化する処理手順について説明する。 The processing procedure for atomizing the sample in the atomizing device unit 1 having the above configuration will be described.
　はじめに、被処理物は有機溶媒中に分散されて試料となる。分散は供給容器３０で行わる。 First, the object to be treated is dispersed in an organic solvent to become a sample. Dispersion is performed in the supply container 30.
　微小化の対象である被処理物は、例えば、セルロース、グラファイト、グラフェン、カーボンナノチューブ、複合金属酸化物（スピネル、ペロブスカイト等の結晶質）等の多岐にわたる物質である。分散を通じて微小化することにより、樹脂等に混合する際の均一な分散性が高まる。そのため、素材の性能向上が見込まれる。 The objects to be treated to be miniaturized are a wide variety of substances such as cellulose, graphite, graphene, carbon nanotubes, and composite metal oxides (crystalline materials such as spinel and perovskite). By miniaturizing through dispersion, uniform dispersibility when mixed with a resin or the like is enhanced. Therefore, the performance of the material is expected to improve.
　次に、弁７１を開くともにプランジャ５１Ｂをシリンダ５１Ａ内から引き出すことで、プランジャポンプ５１のシリンダ５１Ａ内に試料を充填する。そして、弁７１を閉じた状態で、プランジャ５１Ｂをシリンダ５１Ａ内に押し込むことで、試料を、配管４１を介して、微粒化装置１０に供給する（高圧で押し出す）。 Next, by opening the valve 71 and pulling out the plunger 51B from the cylinder 51A, the sample is filled in the cylinder 51A of the plunger pump 51. Then, with the valve 71 closed, the plunger 51B is pushed into the cylinder 51A to supply the sample to the atomizing device 10 (extruded at high pressure) via the pipe 41.
　試料の微粒化が十分でない場合には、プランジャ５１Ｂを押し込むタイミングでは、弁７３を開き、弁７５を閉じた状態にする。前述の構造を有する微粒化装置１０を通過することで微粒化（均一化）された試料は、配管４２、弁７３、配管４３を通って、取出容器３１に供給される。このとき、試料は、配管４３を通る際に、必要に応じて、熱交換器８０によって排熱されてもよい。そして、取出容器３１に供給された試料は再び、供給容器３０に供され、微粒化処理が施される。 If the sample is not sufficiently atomized, the valve 73 is opened and the valve 75 is closed at the timing of pushing the plunger 51B. The sample atomized (uniformized) by passing through the atomizing device 10 having the above-mentioned structure is supplied to the take-out container 31 through the pipe 42, the valve 73, and the pipe 43. At this time, the sample may be exhausted by the heat exchanger 80 as necessary when passing through the pipe 43. Then, the sample supplied to the take-out container 31 is again provided to the supply container 30 and subjected to atomization treatment.
　この動作を複数回繰り返すことにより、試料が微粒化流路を複数回通過する。即ち、複数回にわたって試料が微粒化されるとともに、試料の均一化が実現される。なお、当該処理は、微粒化装置ユニット１に設けられた制御部により実行されてもよいし、オペレータからの指示を受け付けた制御部が実行することとしてもよい。 By repeating this operation multiple times, the sample passes through the atomization flow path multiple times. That is, the sample is atomized a plurality of times, and the sample is made uniform. The process may be executed by the control unit provided in the atomizing device unit 1, or may be executed by the control unit that has received an instruction from the operator.

FIG. 5 is a flowchart showing a manufacturing method of the plunger pump shown in FIG. 6 and 7 are image diagrams when the plunger pump is manufactured by the procedure shown in FIG. A method of manufacturing the plunger pump 51 will be described with reference to FIGS. 5 to 7. In the manufacture of the plunger pump 51, the outer cylinder is made larger (or smaller) than usual by generating a temperature difference from the normal temperature state with respect to either the outer cylinder 51b or the inner cylinder 51a. It is realized that the inner cylinder 51a is inserted into the 51b. In the first embodiment, the outer cylinder 51b is heated to expand its size and the inner cylinder 51a can be inserted. Hereinafter, a specific description will be given.
　まず、図６（ａ）に示すように、内側シリンダ５１ａ及び外側シリンダ５１ｂとして、内側シリンダ５１ａの外径≧外側シリンダ５１ｂの内径となる、内側シリンダ５１ａと外側シリンダ５１ｂを用意する。外側シリンダ５１ｂには、熱膨張する素材を用いる。 First, as shown in FIG. 6A, as the inner cylinder 51a and the outer cylinder 51b, an inner cylinder 51a and an outer cylinder 51b are prepared so that the outer diameter of the inner cylinder 51a ≥ the inner diameter of the outer cylinder 51b. A material that expands thermally is used for the outer cylinder 51b.
　そして、用意した外側シリンダ５１ｂに対して加熱処理を行う（図５のステップＳ５０１）。図６（ｂ）に示すように加熱処理は、外側シリンダ５１ｂに対してのみ行う。加熱処理では、外側シリンダ５１ｂが膨張し、かつ、外側シリンダ５１ｂが熱により損壊しない程度に加熱する。この加熱処理を行うことにより、図６（ｃ）の矢印に示すように、外側シリンダ５１ｂは、熱膨張する。その結果、外側シリンダ５１ｂの内径が広がる（伸長する）ことになる。よって、外側シリンダ５１ｂ内に、内側シリンダ５１ａを圧入しやすくすることができる。 Then, the prepared outer cylinder 51b is heat-treated (step S501 in FIG. 5). As shown in FIG. 6B, the heat treatment is performed only on the outer cylinder 51b. In the heat treatment, the outer cylinder 51b is heated to the extent that it expands and the outer cylinder 51b is not damaged by heat. By performing this heat treatment, the outer cylinder 51b is thermally expanded as shown by the arrow in FIG. 6 (c). As a result, the inner diameter of the outer cylinder 51b expands (extends). Therefore, the inner cylinder 51a can be easily press-fitted into the outer cylinder 51b.
　そこで、図６（ｄ）に示すように、熱膨張している外側シリンダ５１ｂの内部に、内側シリンダ５１ａを挿入（圧入）する（図５のステップＳ５０２も参照）。図７（ａ）は、内側シリンダ５１ａを、外側シリンダ５１ｂの内部に挿入が完了した状態のシリンダ５１Ａを示している。 Therefore, as shown in FIG. 6D, the inner cylinder 51a is inserted (press-fitted) into the thermally expanded outer cylinder 51b (see also step S502 in FIG. 5). FIG. 7A shows a cylinder 51A in a state where the inner cylinder 51a has been inserted into the outer cylinder 51b.
　内側シリンダ５１ａの外側シリンダ５１ｂへの挿入が完了した後に、膨張している外側シリンダ５１ｂを元の状態、即ち、膨張していない状態に戻すために、外側シリンダ５１ｂに対して冷却処理を行う（図５のステップＳ５０３、図７（ｂ）を参照）。冷却処理としては、外側シリンダ５１ｂの加熱、冷却による金属疲労を考慮すると、自然冷却であることが望ましいが、その限りではない。即ち、冷却処理は、人為的に外側シリンダ５１ｂを冷却するものであってもよいし、自然冷却であってもよい。人為的な冷却手法としては、例えば、シリンダ５１Ａを、水を張った水槽につけたりすることが考えられるが、外側シリンダ５１ｂを損壊することなく冷却できれば、どのような手法であってもよい。 After the insertion of the inner cylinder 51a into the outer cylinder 51b is completed, the outer cylinder 51b is cooled (cooled) in order to return the expanded outer cylinder 51b to the original state, that is, the non-expanded state. See step S503 of FIG. 5 and FIG. 7B). As the cooling treatment, natural cooling is desirable in consideration of heating and metal fatigue due to cooling of the outer cylinder 51b, but this is not the case. That is, the cooling process may artificially cool the outer cylinder 51b, or may be natural cooling. As an artificial cooling method, for example, the cylinder 51A may be attached to a water tank filled with water, but any method may be used as long as the outer cylinder 51b can be cooled without being damaged.
　外側シリンダ５１ｂは、冷却されることによって、元の寸法に戻る。したがって、シリンダ５１Ａは、外側シリンダ５１ｂが、常時、内側シリンダ５１ａをその外側から締め付ける構造を有するようになる。一方で、シリンダ５１Ａ内には、微粒化装置の作動時には、内部を高圧で試料が流動する。したがって、その試料から、シリンダに対して、外側に向けた圧力がかかることになり、シリンダの金属疲労を招くことになるが、本実施例に係るシリンダ５１Ａの場合、内側シリンダ５１ａに対して、外側シリンダ５１ｂから外圧がかかる。外側シリンダ５１ｂからの外圧が、内側シリンダ５１ａの内部を流動する試料による内圧と対抗することにより、内側シリンダ５１ａに係る圧力が分散する。したがって、シリンダ５１Ａは、本実施形態に示すように、二重構造とし、外側シリンダ５１ｂが内側シリンダ５１ａに対して外圧を加える構造とすることで、従来よりも、内部を流動する試料からの内圧に対する耐性を向上させることができ、従来よりも疲労度合いを軽減することができる。 The outer cylinder 51b returns to its original dimensions when cooled. Therefore, the cylinder 51A has a structure in which the outer cylinder 51b always tightens the inner cylinder 51a from the outside. On the other hand, when the atomizing device is operated, the sample flows in the cylinder 51A at a high pressure. Therefore, pressure is applied to the cylinder from the sample toward the outside, which causes metal fatigue of the cylinder. However, in the case of the cylinder 51A according to the present embodiment, the pressure is applied to the inner cylinder 51a. External pressure is applied from the outer cylinder 51b. The external pressure from the outer cylinder 51b opposes the internal pressure of the sample flowing inside the inner cylinder 51a, so that the pressure related to the inner cylinder 51a is dispersed. Therefore, as shown in the present embodiment, the cylinder 51A has a double structure, and the outer cylinder 51b applies an external pressure to the inner cylinder 51a, so that the internal pressure from the sample flowing inside is higher than before. It is possible to improve the resistance to the strain and reduce the degree of fatigue as compared with the conventional case.
　外側シリンダ５１ｂの冷却が終了すると、次に、シリンダ５１Ａに、プランジャ５１Ｂを挿入する（図５のステップＳ５０４、図７（ｃ）参照）。これにより、プランジャポンプ５１を製造することができる。 When the cooling of the outer cylinder 51b is completed, the plunger 51B is then inserted into the cylinder 51A (see step S504 and FIG. 7C in FIG. 5). As a result, the plunger pump 51 can be manufactured.
＜実施の形態２＞
　上記実施の形態１においては外側シリンダ５１ｂを加熱して膨張させることによって、内側シリンダ５１ａを挿入し、その後に、外側シリンダ５１ｂを冷却して元のサイズに戻すことで、内側シリンダ５１ａに対して外圧を印加する構成を実現した。本実施の形態２においては、シリンダ５１Ａの製造方法の他の例を説明する。 <Embodiment 2>
In the first embodiment, the inner cylinder 51a is inserted by heating and expanding the outer cylinder 51b, and then the outer cylinder 51b is cooled and returned to the original size with respect to the inner cylinder 51a. A configuration that applies external pressure has been realized. In the second embodiment, another example of the method for manufacturing the cylinder 51A will be described.
　上記実施の形態１においては、外側シリンダ５１ｂを加熱することで、通常時よりもサイズを大きくすることで、内側シリンダ５１ａを挿入できるようにしたが、本実施の形態２においては、内側シリンダ５１ａを小さくすることで、外側シリンダ５１ｂに挿入できるようにする製造方法を説明する。 In the first embodiment, the inner cylinder 51a can be inserted by heating the outer cylinder 51b to make the size larger than usual, but in the second embodiment, the inner cylinder 51a can be inserted. A manufacturing method will be described in which the cylinder can be inserted into the outer cylinder 51b by reducing the size.
　図８は、本実施の形態２に係るプランジャポンプ５１の製造方法を示すフローチャートである。また、図９、図１０は、図８に示すフローチャートによる製造方法のイメージ図である。 FIG. 8 is a flowchart showing a manufacturing method of the plunger pump 51 according to the second embodiment. 9 and 10 are image diagrams of the manufacturing method according to the flowchart shown in FIG.
　まず、図９（ａ）に示すように、内側シリンダ５１ａ及び外側シリンダ５１ｂとして、内側シリンダ５１ａの外径≧外側シリンダ５１ｂの内径となる、内側シリンダ５１ａと外側シリンダ５１ｂを用意する。内側シリンダ５１ａには、冷却により寸法が収縮する素材を用いる。 First, as shown in FIG. 9A, as the inner cylinder 51a and the outer cylinder 51b, an inner cylinder 51a and an outer cylinder 51b are prepared so that the outer diameter of the inner cylinder 51a ≥ the inner diameter of the outer cylinder 51b. For the inner cylinder 51a, a material whose size shrinks due to cooling is used.
　そして、用意した内側シリンダ５１ａに対して冷却処理を行う（図８のステップＳ８０１）。図８（ｂ）に示すように冷却処理は、内側シリンダ５１ａに対してのみ行う。冷却処理では、内側シリンダ５１ａが収縮し、かつ、内側シリンダ５１ａが冷却により損壊しない（劣化しない）程度に冷却する。この冷却処理を行うことにより、図９（ｃ）の矢印に示すように、内側シリンダ５１ａは、収縮する。その結果、内側シリンダ５１ａの外径が収縮（短くなる）ことになる。よって、外側シリンダ５１ｂ内に、内側シリンダ５１ａを圧入しやすくすることができる。 Then, the prepared inner cylinder 51a is cooled (step S801 in FIG. 8). As shown in FIG. 8B, the cooling process is performed only on the inner cylinder 51a. In the cooling process, the inner cylinder 51a is cooled to such an extent that the inner cylinder 51a contracts and the inner cylinder 51a is not damaged (deteriorated) by cooling. By performing this cooling process, the inner cylinder 51a contracts as shown by the arrow in FIG. 9C. As a result, the outer diameter of the inner cylinder 51a is contracted (shortened). Therefore, the inner cylinder 51a can be easily press-fitted into the outer cylinder 51b.
　そこで、図９（ｄ）に示すように、外側シリンダ５１ｂの内部に、収縮している内側シリンダ５１ａを挿入（圧入）する（図８のステップＳ８０２も参照）。図１０（ａ）は、内側シリンダ５１ａを、外側シリンダ５１ｂの内部に挿入が完了した状態のシリンダ５１Ａを示している。 Therefore, as shown in FIG. 9D, the contracting inner cylinder 51a is inserted (press-fitted) inside the outer cylinder 51b (see also step S802 in FIG. 8). FIG. 10A shows the cylinder 51A in a state where the inner cylinder 51a is completely inserted into the outer cylinder 51b.
　内側シリンダ５１ａの外側シリンダ５１ｂへの挿入が完了した後に、収縮している内側シリンダ５１ａを元の状態、即ち、収縮していない状態に戻すために、内側シリンダ５１ａに対して加熱処理を行う（図８のステップＳ８０３、図１０（ｂ）を参照）。加熱処理としては、内側シリンダ５１ａの冷却、加熱による金属疲労を考慮すると、自然加熱（自然に常温になるのを待つ）であることが望ましいが、その限りではない。即ち、加熱処理は、人為的に内側シリンダ５１ａを加熱するものであってもよい人為的な冷却手法としては、例えば、シリンダ５１Ａを、お湯を張った浴槽につけたりすることが考えられるが、内側シリンダ５１ａを損壊することなく加熱できれば、どのような手法であってもよい。なお、このときに、加熱処理によって、外側シリンダ５１ｂが膨張しないことが望ましい。 After the insertion of the inner cylinder 51a into the outer cylinder 51b is completed, the inner cylinder 51a is heat-treated in order to return the contracted inner cylinder 51a to the original state, that is, the non-shrinked state ( See step S803 and FIG. 10B in FIG. 8). The heat treatment is preferably natural heating (waiting for the temperature to reach room temperature naturally) in consideration of cooling of the inner cylinder 51a and metal fatigue due to heating, but this is not the case. That is, as an artificial cooling method in which the heat treatment may artificially heat the inner cylinder 51a, for example, it is conceivable to attach the cylinder 51A to a bathtub filled with hot water. Any method may be used as long as the cylinder 51a can be heated without being damaged. At this time, it is desirable that the outer cylinder 51b does not expand due to the heat treatment.
　内側シリンダ５１ａは、加熱されることによって、元の寸法に戻る。一方で、外側シリンダ５１ｂ自体は元のサイズのままである。したがって、シリンダ５１Ａは、外側シリンダ５１ｂが、常時、内側シリンダ５１ａをその外側から締め付ける構造を有するようになる。一方で、シリンダ５１Ａ内には、微粒化装置の作動時には、内部を高圧で試料が流動する。したがって、その試料から、シリンダに対して、外側に向けた圧力がかかることになり、シリンダの金属疲労を招くことになるが、本実施例に係るシリンダ５１Ａの場合、内側シリンダ５１ａに対して、外側シリンダ５１ｂから外圧がかかる。外側シリンダ５１ｂからの外圧が、内側シリンダ５１ａの内部を流動する試料による内圧と対抗することにより、内側シリンダ５１ａに係る圧力が分散する。したがって、シリンダ５１Ａは、本実施形態に示すように、二重構造とし、外側シリンダ５１ｂが内側シリンダ５１ａに対して外圧を加える構造とすることで、従来よりも、内部を流動する試料からの内圧に対する耐性を向上させることができ、従来よりもシリンダ５１Ａの金属疲労度合いを軽減することができる。 The inner cylinder 51a returns to its original dimensions by being heated. On the other hand, the outer cylinder 51b itself remains in its original size. Therefore, the cylinder 51A has a structure in which the outer cylinder 51b always tightens the inner cylinder 51a from the outside. On the other hand, when the atomizing device is operated, the sample flows in the cylinder 51A at a high pressure. Therefore, pressure is applied to the cylinder from the sample toward the outside, which causes metal fatigue of the cylinder. However, in the case of the cylinder 51A according to the present embodiment, the pressure is applied to the inner cylinder 51a. External pressure is applied from the outer cylinder 51b. The external pressure from the outer cylinder 51b opposes the internal pressure of the sample flowing inside the inner cylinder 51a, so that the pressure related to the inner cylinder 51a is dispersed. Therefore, as shown in the present embodiment, the cylinder 51A has a double structure, and the outer cylinder 51b applies an external pressure to the inner cylinder 51a, so that the internal pressure from the sample flowing inside is higher than before. It is possible to improve the resistance to resistance to the cylinder 51A and reduce the degree of metal fatigue of the cylinder 51A as compared with the conventional case.
　内側シリンダ５１ａの加熱が終了すると、次に、シリンダ５１Ａに、プランジャ５１Ｂを挿入する（図８のステップＳ８０４、図１０（ｃ）参照）。これにより、プランジャポンプ５１を製造することができる。 When the heating of the inner cylinder 51a is completed, the plunger 51B is then inserted into the cylinder 51A (see step S804 and FIG. 10C in FIG. 8). As a result, the plunger pump 51 can be manufactured.
＜変形例＞
　上記実施の形態１においては、加熱処理により外側シリンダ５１ｂを膨張させることで、外側シリンダ５１ｂ内に内側シリンダ５１ａを挿入し、実施の形態２においては、冷却処理により内側シリンダ５１ａを収縮させることで、内側シリンダ５１ａを外側シリンダ５１ｂ内に挿入した。しかし、これは、内径が内側シリンダ５１ａの外径よりも小さい外側シリンダ５１ｂ内に、内側シリンダ５１ａを挿入さえできればよく、加熱処理や冷却処理以外の手法を用いてもよいことはいうまでもない。例えば、外側シリンダ５１ｂを機械的に把持し、そこにロボットマシーン等により内側シリンダ５１ａを圧入させることとしてもよい。内側シリンダ５１ａを外側シリンダ５１ｂに圧入することにより、上記実施の形態１、２に示したシリンダ５１Ａと同等の構成を実現することができる。 <Modification example>
In the first embodiment, the inner cylinder 51a is inserted into the outer cylinder 51b by expanding the outer cylinder 51b by heat treatment, and in the second embodiment, the inner cylinder 51a is contracted by cooling treatment. , The inner cylinder 51a was inserted into the outer cylinder 51b. However, it goes without saying that a method other than heat treatment or cooling treatment may be used as long as the inner cylinder 51a can be inserted into the outer cylinder 51b whose inner diameter is smaller than the outer diameter of the inner cylinder 51a. .. For example, the outer cylinder 51b may be mechanically gripped, and the inner cylinder 51a may be press-fitted into the outer cylinder 51b by a robot machine or the like. By press-fitting the inner cylinder 51a into the outer cylinder 51b, a configuration equivalent to that of the cylinder 51A shown in the first and second embodiments can be realized.
　また、上記手法によりシリンダ５１Ａを製造することにより、定常状態において、外側シリンダ５１ｂが内側シリンダ５１ａに対して圧力を加える構成を実現している。これは、前述の通り、微粒化装置の作動時における内側シリンダ５１ａ内の内圧と拮抗させるための構成であるが、内側シリンダ５１ａに対して外圧がかかるように構成されていれば、他の構成によって実現されてもよい。例えば、微粒化装置の動作時において、シリンダ５１Ａに対して外圧を印加する装置を付加してもよい。例えば、シリンダ５１Ａに対して微粒化装置の作動時に、油圧をかける装置にかけて、シリンダ５１Ａに外圧を加える構成としてもよいし、万力等の装置により、シリンダ５１Ａに外圧を加えるように構成してもよい。 Further, by manufacturing the cylinder 51A by the above method, the outer cylinder 51b applies pressure to the inner cylinder 51a in a steady state. As described above, this is a configuration for competing with the internal pressure in the inner cylinder 51a when the atomizing device is operated, but if it is configured so that an external pressure is applied to the inner cylinder 51a, another configuration is used. May be realized by. For example, a device that applies an external pressure to the cylinder 51A may be added during the operation of the atomizing device. For example, an external pressure may be applied to the cylinder 51A by applying hydraulic pressure to the cylinder 51A when the atomizing device is operated, or an external pressure may be applied to the cylinder 51A by a device such as a vise. May be good.
　＜まとめ＞

Can be provided. Therefore, the degree of fatigue of the cylinder 51A can be reduced more than before by facing the pressure from the outer cylinder 51b to the inner cylinder 51a with respect to the internal pressure from the sample flowing in the cylinder 51A of the plunger pump 51 at a high pressure. it can.
　なお、上記実施形態においては、微粒化装置ユニット１においては、試料を一方向にのみ流動することとなっているが、微粒化装置１０を往復道する構成をとってもよい。即ち、図１において、ドレン８６が設けられている箇所に、別のプランジャポンプを設けて、微粒化装置１０内を試料が往復するような構成をとってもよい。 In the above embodiment, in the atomizing device unit 1, the sample flows in only one direction, but the atomizing device 10 may be reciprocated.
