Description

本発明は、対峙シンメトリー型プランジャーポンプで、気体の吸気・排気の構造に関する。The present invention relates to a gas intake / exhaust structure of an anti-symmetrical plunger pump.

従来、容積型圧縮機は、ピストン往復運動を、クランク回転構造でトルク変動が大きく、低速回転で騒音・振動が高く、効率が低い。Conventionally, positive displacement compressors have a piston reciprocating motion that has a large torque fluctuation due to a crank rotation structure, a high noise / vibration at low speed rotation, and a low efficiency.

上記の課題を解決するため、対峙するプランジャーポンプ１対を、直線上に配し、往復工程を高速駆動して、ポンプの吸気・排気の増加を図る。In order to solve the above problems, a pair of plunger pumps facing each other are arranged on a straight line, and the reciprocation process is driven at a high speed to increase the intake and exhaust of the pump.

上記課題解決に、本発明は、対峙する１対のプランジャーポンプシリンダー内に往復するピストンを、回転カムの変位を小さくし、往復行程をピストン直径より、小さくし、高速化を図り、更にプランジャーポンプの多連組合せで、気体吐出圧力・吐出量を増加させる。In order to solve the above-mentioned problems, the present invention provides a piston that reciprocates in a pair of plunger pump cylinders facing each other with a reduced displacement of the rotating cam, a reciprocating stroke smaller than the piston diameter, and a higher speed. Increase gas discharge pressure and discharge volume with multiple combinations of jar pumps.

本発明は、圧縮空気生成装置で、空気生成に用いるエネルギーを削減し、環境・資源保護に寄与する。The present invention is a compressed air generating device that reduces energy used for air generation and contributes to environmental and resource protection.

図１は、対峙シンメトリー型カム駆動プランジャーポンプの断面概略図である。
気体吸気Ａと圧縮排気Ｅはプランジャーポンプの往復運動Ｓの反復動作で行う。
カムシャフト１にセットしたカム２・フライホイル２′を円滑に回転し、カムフォロア３を介し、シリンダー６内部の組合せたピストンロッド４・ピストン５で、交互に吸排気を繰返す。プランジャーポンプの構成は、対峙１対のため、在来の空気圧縮機の２気筒分の作業を２の回転で、実施し、５は２回動作する。５の直径よりも２の変位Ｄを縮め、５のＳを短縮し、２の輪郭に３が確実に追従するため、マウントベース９に固定したガイドポスト１０を往復する、リニアモーションベアリング１１を組付けたガイドベース１２に４を固定し、１２にテンションスプリング１３を取付け、確動カムとして、Ｓを確実に実施し、高速駆動を安定させる。
ＡとＥの切替は、シリンダーヘッド７に設けた吸気用チャンバー１４内吸気ボール１４′と、排気用チャンバー１７内で排気ボール１７′を５のＳで実行する。FIG. 1 is a schematic cross-sectional view of an anti-symmetrical cam-driven plunger pump.
The gas intake A and the compressed exhaust E are performed by repetitive operations of the reciprocating motion S of the plunger pump.
The cam 2 and flywheel 2 ′ set on the camshaft 1 are smoothly rotated, and intake and exhaust are repeated alternately by the piston rod 4 and piston 5 combined inside the cylinder 6 via the cam follower 3. Since the plunger pump has one pair, the operation of two cylinders of a conventional air compressor is performed by two rotations, and 5 operates twice. The linear motion bearing 11 is assembled to reciprocate the guide post 10 fixed to the mount base 9 in order to reduce the displacement D of 2 from the diameter of 5 and shorten S of 5 to ensure that 3 follows the contour of 2. 4 is fixed to the attached guide base 12 and a tension spring 13 is attached to the guide base 12, and S is reliably implemented as a positive cam to stabilize high-speed driving.
Switching between A and E is performed by S of 5 for the intake ball 14 ′ in the intake chamber 14 provided in the cylinder head 7 and the exhaust ball 17 ′ in the exhaust chamber 17.

図２は、シリンダーヘッド７の断面図である。
７に設けた吸気用チャンバー１４・吸気ボール１４′（軽比重材質）と排気用チャンバー１７・排気ボール１７′（軽比重材質）は、それぞれにＡ・Ｅに同期してボールバルブとして、作用するもので、個々の工程で、１４′・１７′が開放時に脱落を防止するため、吸気用ワイヤーゲージネット１５・排気用ワイヤーゲージネット１８を設ける。FIG. 2 is a cross-sectional view of the cylinder head 7.
The intake chamber 14 and intake ball 14 '(light specific gravity material) and the exhaust chamber 17 and exhaust ball 17' (light specific gravity material) provided in 7 act as ball valves in synchronization with A and E, respectively. In order to prevent the 14 'and 17' from falling off when opened, an intake wire gauge net 15 and an exhaust wire gauge net 18 are provided in each process.

図３は、ピストン５の断面図である。
５のＳは高速運転のため、Ｅの気体が圧縮工程で温度が上昇するので、５の下部に冷却フィンを設け、シリンダーボトム８・マウントベース９の空洞部を５のＳで強制流動する外気利用で４・５・６の温度上昇を軽減する。FIG. 3 is a sectional view of the piston 5.
Since the temperature of S in 5 is high-speed operation, the temperature of E gas rises in the compression process. Therefore, a cooling fin is provided at the bottom of 5 and the outside air forcibly flows in the cavity of cylinder bottom 8 and mount base 9 with S in 5 Use to reduce the temperature rise of 4, 5, 6

省エネルギー空気圧縮機の必要性で、消費電力削減目的の為、需要性大。The need for an energy-saving air compressor is high and demand is high for the purpose of reducing power consumption.
