Abstract
본 발명은 압력이 자동조절되는 플런저 펌프의 패킹구조에 관한 것이다.The present invention relates to a packing structure of a plunger pump in which pressure is automatically adjusted.
왕복펌프(Riciprocating Pump)의 일종인 플런저 펌프(Plunger Pump)는 크랭크 기구ㆍ플런저ㆍ실린더ㆍ흡입밸브ㆍ송출밸브ㆍ흡입구ㆍ토출구 등으로 크게 구성되며, 상기 플런저(Plunger)는 크랭크 기구에 의해 실린더 내부를 직선왕복운동하면서 진공압력(흡입압력)과 토출압력을 발생시키고, 상기 진공압력과 토출압력은 펌프블럭으로 곧바로 전달되고, 상기 펌프블럭는 유체(水)를 흡입한 다음 고압으로 토출하게 되며, 비록 송출유량은 적지만 주로 고압토출이 요구될 때 사용된다.The plunger pump, a kind of reciprocating pump, is composed of a crank mechanism, a plunger, a cylinder, a suction valve, a discharge valve, a suction port, a discharge port, and the like. While generating a vacuum pressure (suction pressure) and a discharge pressure while linearly reciprocating, the vacuum pressure and the discharge pressure are directly transmitted to the pump block, and the pump block inhales the fluid and then discharges it at a high pressure. Although the flow rate is small, it is mainly used when high pressure discharge is required.
상기 플런저는 실린더 속을 고속으로 왕복운동하는 구성이고 고압이 작용되는 실린더와 플런저 사이에는 압력에 의한 누수방지를 위하여 신뢰성이 우수한 패킹이 설치된다. 상기 패킹은 압력누수를 방지하기 위하여 플런저와의 강한 밀착이 유지되어야 하는 바, 종래 플런저 펌프는 단순히 수밀을 달성하기 위한 구조이므로 압력정도에 따라 패킹이 플런저를 따라 움직이거나 유동되면서 수밀성이 떨어지고 패킹이 쉽게 마모될 뿐 아니라 저항손실이 증가하여 펌프의 효율이 나빠지는 문제점이 있었다.The plunger is configured to reciprocate at a high speed in the cylinder, and a highly reliable packing is installed between the cylinder and the plunger where high pressure is applied to prevent leakage due to pressure. The packing should be maintained in close contact with the plunger in order to prevent pressure leakage, the conventional plunger pump is simply a structure to achieve water tightness, so the packing is moved or flowed along the plunger according to the pressure degree, the watertightness falls and the packing is Not only was it easily worn, but there was a problem that the efficiency of the pump is worsened by increasing the resistance loss.
따라서, 본 발명은 플런저 펌프의 흡입밸브 하단에 스프링을 장착시킨 다음 상기 스프링에 부시(Bush)를 연결하여 패킹에 밀착시킴으로서 플런저가 하강하는 흡입행정 시에 흡입밸브가 하강하여 스프링이 압축되면 패킹의 압력이 자동으로 조절되면서 수밀성과 펌프효율이 크게 향상되도록 한 것이다.Therefore, in the present invention, the spring is mounted on the lower end of the suction valve of the plunger pump and then a bush is connected to the spring to closely adhere to the packing. The pressure is automatically adjusted to improve water tightness and pump efficiency.
Description
본 발명은 압력이 자동조절되는 플런저 펌프의 패킹구조에 관한 것으로, 상세하게는 플런저 펌프의 흡입밸브 하단에 스프링을 장착시킨 다음 상기 스프링에 부시(Bush)를 연결하여 패킹에 밀착시킴으로서 플런저가 하강하는 흡입행정 시에 흡입밸브가 하강하여 스프링이 압축되면 패킹의 압력이 자동으로 조절되어 수밀성과 펌프효율이 크게 향상되도록 한 것이다.The present invention relates to a packing structure of a pressure-adjusted plunger pump, and more particularly, by mounting a spring at the bottom of the intake valve of the plunger pump and then attaching a bush to the spring to bring the plunger into close contact with the packing. When the suction valve is lowered during the suction stroke and the spring is compressed, the packing pressure is automatically adjusted so that the water tightness and the pump efficiency are greatly improved.
왕복펌프(Riciprocating Pump)의 일종인 플런저 펌프(Plunger Pump)는 크랭크기구ㆍ플런저ㆍ실린더ㆍ흡입밸브ㆍ송출밸브 등으로 크게 구성되며, 크랭크 기구에 의해 플런저가 실린더 내부를 직선 왕복운동하면서 진공압력(흡입압력)과 토출압력을 발생시키게 된다.The plunger pump, a kind of reciprocating pump, is composed of a crank mechanism, a plunger, a cylinder, a suction valve, a discharge valve, and the like.The crank mechanism causes the plunger to linearly reciprocate inside the cylinder, Suction pressure) and discharge pressure.
상기 진공압력과 토출압력은 펌프블럭로 곧바로 전달되어 유체를 흡입한 다음 고압으로 토출하게되며, 플런저 펌프의 토출용량을 높이기 위하여 복수 개의 플런저 펌프를 병렬로 접속하여 2련식 3련식 또는 그 이상으로 구성하기도 한다.The vacuum pressure and the discharge pressure are delivered directly to the pump block to suck the fluid and discharge the fluid at high pressure, and in order to increase the discharge capacity of the plunger pump, a plurality of plunger pumps are connected in parallel to constitute a triple triple type or more. Sometimes.
한편, 플런저 펌프는 왕복 직선운동하는 플런저의 축동요와 마찰열을 고려하여 플런저와 실린더의 내벽 사이는 어느 정도의 간극을 두고 있으며, 이러한 연유로 실린더와 플런저 사이의 수밀과 밀폐를 확보하기 위하여 복수 개의 V 패킹(또는 U 패킹)이 설치된다.On the other hand, the plunger pump has a certain gap between the plunger and the inner wall of the cylinder in consideration of the axial fluctuations and frictional heat of the reciprocating linear motion of the plunger. V packing (or U packing) is installed.
실린더와 플런저 사이에 설치되는 패킹은 압력 누수를 방지하기 위하여 플런저와의 강한 밀착이 유지되어야 하는바, 종래 플런저 펌프의 경우 단순히 결합되어 있으므로 압력정도에 따라 패킹이 플런저를 따라 움직이거나 유동되고, 패킹의 움직임이나 유동에 따라 기밀성 또는 수밀성이 떨어지고 패킹이 쉽게 마모될 뿐 아니라 저항손실이 증가하여 펌프효율이 나빠지는 문제점이 있다.The packing installed between the cylinder and the plunger should be maintained in close contact with the plunger to prevent pressure leakage. In the case of the conventional plunger pump, the packing is simply combined so that the packing moves or flows along the plunger depending on the pressure. The airtightness or watertightness is lowered according to the movement or flow of the packing, and the packing is not easily worn, and there is a problem that the pump efficiency becomes worse due to an increase in resistance loss.
또한, 도면으로 도시하지 않았지만 고압에 의해 플런저와 실린더 또는 플런저와 플런저 케이스 사이로 누수되는지를 수시로 관찰하여 누수가 확인되면 플런저 케이스의 후단에 체결되는 너트캡을 죄임시켜 패킹을 가압하는 방식으로 누수를 방지하게 되므로 사용상의 불편함이 있었다.In addition, although not shown in the drawings, if the leakage is confirmed from time to time by observing the leakage between the plunger and the cylinder or the plunger and the plunger case by high pressure, by tightening the nut cap fastened to the rear end of the plunger case to prevent leakage There was an inconvenience in using it.
따라서, 본 발명은 플런저 펌프의 흡입밸브 하단에 스프링을 장착시킨 다음 상기 스프링에 부시(Bush)를 연결하여 패킹에 밀착시킴으로서 플런저가 하강하는 흡입행정 시에 흡입밸브가 하강하여 스프링이 압축되면 패킹의 압력이 자동으로 조절되면서 수밀성과 펌프효율이 크게 향상되도록 함을 목적으로 한다.Therefore, in the present invention, the spring is mounted on the lower end of the suction valve of the plunger pump and then a bush is connected to the spring to closely adhere to the packing. The pressure is automatically adjusted to improve water tightness and pump efficiency.
상기 목적을 달성하기 위하여 플런저 펌프의 플런저와 실린더 사이에 형성되는 간극 부분에 복수 개의 V 패킹과 부시와 스프링과 밸브디스크를 차례로 설치하고, V 패킹의 선ㆍ후단에는 패킹 지지링을 설치하여 플런저가 왕복 직선운동할 때 V 패킹의 후단은 실린더의 내향 돌출부에 걸림되고, V 패킹의 선단은 스프링의 탄발력에 의해 전진이 방지되면서 압력이 자동 조절되도록 한다.In order to achieve the above object, a plurality of V packings, bushes, springs, and valve discs are sequentially installed in the gap portion formed between the plunger and the cylinder of the plunger pump, and the plunger is installed at the front and rear ends of the V packing. In the reciprocating linear motion, the rear end of the V packing is engaged with the inward protrusion of the cylinder, and the front end of the V packing allows the pressure to be automatically adjusted while preventing forward movement by the spring force.
그리고, 스프링에 의해 V 패킹의 완충이 이루어지고 V 패킹의 마모나 손상 및 누수가 방지되므로 V 패킹의 수명이 다할 때 까지 유지보수가 불필요하며, 따라서 종래처럼 수밀유지를 위한 너트캡과 너트캡을 조여주는 등의 번거로움이 없어진다.Since the V packing is buffered by the spring and the wear, damage and leakage of the V packing are prevented, maintenance is unnecessary until the end of the life of the V packing. Trouble such as tightening is eliminated.
본 발명에서 지지링과 부시와 스프링의 내경은 플런저의 외경보다 조금 크게 형성하여 접촉하지 않도록 함으로서 마모 및 마찰열 발생을 억제하고 플런저의 축동요를 방지하도록 한다.In the present invention, the inner diameter of the support ring, the bush and the spring is formed to be slightly larger than the outer diameter of the plunger to prevent contact and to prevent wear and frictional heat generation and to prevent the plunger rocking.

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 단면 구성도이고, 도 2는 부분 절개한 상태의 분해사시도로, 플런저와 실린더의 결합부에 수밀용 V 패킹이 설치된 플런저 펌프에 있어서 ; 플런저(2)와 실린더(4)의 내벽 사이에 형성되는 간극 부분에 복수 개의 V 패킹(8)과 부시(10)와 스프링(12)과 흡입밸브(14)를 차례로 설치하고, V 패킹(8)의 선ㆍ후단에는 패킹 지지링(16)(18)을 설치하여 플런저 펌프(20)를 구성한 것이다.1 is a cross-sectional configuration diagram of the present invention, Figure 2 is an exploded perspective view of a partially cut state, in the plunger pump provided with a water-tight V-packing portion of the coupling portion of the plunger and the cylinder; In the gap formed between the plunger 2 and the inner wall of the cylinder 4, a plurality of V packings 8, a bush 10, a spring 12, and a suction valve 14 are sequentially installed, and the V packing 8 The packing support rings (16, 18) are installed at the front and rear ends of the slit to form the plunger pump 20.
상기 패킹 지지링(16)(18)은 V 패킹(8)보다 다소 경질의 재질을 사용함이 바람직하며, V 패킹(8)이 결합되는 만큼 V 형상의 요입홈과 돌출부가 각각 형성된다.Preferably, the packing support rings 16 and 18 use a somewhat harder material than the V packing 8, and the V-shaped recessed grooves and the protrusions are respectively formed as the V packing 8 is coupled.
후단에 위치하는 지지링(16)은 실린더(4)의 내향 돌출부(22)에 걸림되고 선단에 위치하는 지지링(18)은 부시(10)의 후단에 접촉되며, 부시(10)의 선단 요입홈(24)에는 스프링(12)의 후단이 끼워져 탄지되고, 스프링(12)의 선단은 흡입밸브(14)에 접촉된다.The support ring 16 positioned at the rear end is engaged with the inward protrusion 22 of the cylinder 4, and the support ring 18 positioned at the front end is in contact with the rear end of the bush 10. The rear end of the spring 12 is fitted into the mouth groove 24 to be gripped, and the tip of the spring 12 is in contact with the suction valve 14.
따라서, 크랭크 기구와 같은 동력전달수단에 의해 플런저(2)가 왕복 직선운동할 때, V 패킹(8)의 후단은 실린더(4)의 내향 돌출부(22)에 의해 그 후퇴가 방지되고, V 패킹(8)의 선단은 스프링(12)의 탄발력에 의해 그 전진이 방지되므로 V 패킹(8)의 유동이나 움직임이 방지되며, V 패킹(8)과 플런저(2)의 강한 밀착이 유지된다.Therefore, when the plunger 2 reciprocates linearly by a power transmission means such as a crank mechanism, the rear end of the V packing 8 is prevented from retreating by the inward protrusion 22 of the cylinder 4, and the V packing is prevented. Since the front end of (8) is prevented from moving forward by the spring force of the spring 12, the flow or movement of the V packing 8 is prevented, and the strong packing between the V packing 8 and the plunger 2 is maintained.
또한, 플런저(2)가 하강하는 흡입행정 시에 유체(물)가 흡입되면 흡입력에 의해 흡입밸브(14)가 하강하면서 스프링(12)이 압축되며, 스프링(12)의 압축력이 부시(10)로 전달되고 V 패킹(8)의 압력이 자동으로 조절되면서 플런저(2)에 밀착되므로 V 패킹(8)의 기밀과 수밀이 유지된다.In addition, when fluid (water) is sucked in the suction stroke in which the plunger 2 descends, the spring 12 is compressed while the suction valve 14 is lowered by the suction force, and the compression force of the spring 12 is the bush 10. And the pressure of the V packing 8 is automatically adjusted to be in close contact with the plunger 2 to maintain the airtightness and watertightness of the V packing 8.
그리고, 플런저(2)가 상승 전진할 때 작용(인가)되는 고압 때문에 V 패킹(8)이 후방으로 밀리면서 양호한 수밀이 이루어지며, 스프링(12)에 의해 V 패킹(8)의 완충이 이루어지므로 V 패킹(8)의 마모나 손상 및 누수가 방지되므로 V 패킹(8)의 수명이 다할 때 까지 유지보수가 불필요하다. 그리고, 종래 처럼 너트캡을 조여주는 등의 번거로움이 없어지고 수밀유지를 위한 너트캡 등의 조임구조가 불필요하여 구성이 간단하고 원가가 절감된다.Since the V packing 8 is pushed backward due to the high pressure that is applied (applied) when the plunger 2 is moved forward, good watertightness is achieved, and the V packing 8 is buffered by the spring 12. Since the V packing 8 is prevented from being worn, damaged or leaked, maintenance is not necessary until the life of the V packing 8 is reached. In addition, the hassle of tightening the nut cap is eliminated as in the related art, and a tightening structure such as a nut cap for watertight maintenance is unnecessary, thereby simplifying the construction and reducing the cost.
V 패킹(8)의 움직임이나 유동이 방지됨에 따라 기밀성 또는 수밀성이 크게 향상되고, V 패킹(8)의 마찰열 또한 크게 감소하여 수명이 증대되며 펌프효율도 크게 향상된다.As the movement or flow of the V packing 8 is prevented, the airtightness or water tightness is greatly improved, and the frictional heat of the V packing 8 is also greatly reduced to increase the service life and the pump efficiency.
본 발명에서 지지링(16)(18)과 부시(10)와 스프링(12)의 내경은 플런저(2)의 외경보다 조금 크게 형성하여 접촉하지 않도록 함으로서 이들의 마모와 마찰열 발생이 억제되고 또한 플런저(2)의 축동요가 방지된다.In the present invention, the inner diameters of the support rings 16 and 18, the bush 10 and the spring 12 are formed to be slightly larger than the outer diameter of the plunger 2 so that they do not come into contact with each other so that their wear and frictional heat are suppressed and the plunger is also suppressed. Shaking vibration of (2) is prevented.
상기 플런저(2)는 크랭크 기구와 같은 동력전달수단에 의해 실린더(4) 내부를 직선 왕복운동하면서 진공압력(흡입압력)과 토출압력을 발생시키게 되며, 상기 진공압력과 토출압력은 펌프블럭(28)으로 곧바로 전달되므로 유체를 흡입한 다음 고압으로 토출하게 된다.The plunger 2 generates a vacuum pressure (suction pressure) and a discharge pressure while linearly reciprocating the inside of the cylinder 4 by a power transmission means such as a crank mechanism, and the vacuum pressure and the discharge pressure are pump blocks 28. As it is delivered directly to), the fluid is sucked and then discharged at high pressure.
상기 플런저(2)와 실린더(4)는 플런저 케이스(26)에 결합 및 고정된다.The plunger 2 and the cylinder 4 are coupled to and fixed to the plunger case 26.
그리고, 플런저 케이스(26)와 펌프블럭(28)는 분리ㆍ결합할 수 있게 길이가 긴 너트(29)로 체결되며, 펌프블럭(28)에는 흡입실(30)과 토출실(32)과 흡입구(34)와 토출구(36)와 흡입밸브(38)와 토출밸브(40)와 밸브블록(42)과 흡입공(44)과 유공(46)과 토출공(48)과 연결공(50)과 스프링(52) 등이 각각 설치되며 플런저(2)의 운동에 의해 발생되는 압력차이로 유체(流體)가 흡입 및 토출된다.The plunger case 26 and the pump block 28 are fastened by a nut 29 having a long length so as to be separated and coupled, and the pump block 28 has a suction chamber 30, a discharge chamber 32, and a suction port. (34), the discharge port 36, the suction valve 38, the discharge valve 40, the valve block 42, the suction hole 44, the oil hole 46, the discharge hole 48 and the connecting hole 50 and Springs 52 and the like are respectively provided, and fluid is sucked and discharged due to the pressure difference generated by the movement of the plunger 2.
상기 스프링(12)의 탄발력은 헤드케이스(70)에 설치되는 스프링(52)의 탄발력과 같거나 같은 수준으로 하여 평소에 흡입밸브(14)의 중립성을 유지하도록 한다.The spring force of the spring 12 is equal to or equal to the spring force of the spring 52 installed in the head case 70 so as to maintain the neutrality of the suction valve 14 at normal times.

이상과 같이 설명한 본 발명은 전술한 실시 예 및 첨부된 도면으로 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러가지 치환, 변형 및 변경이 가능하며, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 자명한 것이다.The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention, and this is in the technical field to which the present invention belongs. It is self-evident for those of ordinary knowledge.
이상과 같이 본 발명은 플런저 펌프의 흡입밸브 하단에 스프링을 장착시킨 다음 상기 스프링에 부시(Bush)를 연결하여 패킹에 밀착시킴으로서 플런저가 하강하는 흡입행정 시에 흡입밸브가 하강하여 스프링이 압축되면 패킹의 압력이 자동으로 조절되고 그 유동이 방지되어 수밀성과 펌프효율은 크게 향상되고 사용수명은 연장되는 효과가 있다.As described above, the present invention mounts a spring at the lower end of the intake valve of the plunger pump and connects a bush to the spring to closely adhere to the packing so that the intake valve is lowered during the intake stroke of the plunger descending and the spring is compressed. Its pressure is automatically adjusted and its flow is prevented, so that the watertightness and pump efficiency are greatly improved, and the service life is extended.
또한, 종래의 경우 유체가 누수되는지 수시로 확인하면서 너트캡을 조여 패킹의 수밀을 유지하는 구성이므로 관리상의 번거로운 문제점이 있었으나, 본 발명은 스프링과 압력에 의해 패킹의 강한 밀착과 유동이 방지되어 수밀성과 펌프효율이 크게 향상되고 사용수명이 보다 연장되므로 종래처럼 너트캡을 수시로 죄임할 필요가 없으며, 패킹의 수명이 다할 때 까지 유지보수가 불 필요한 장점이 있다.In addition, in the conventional case, it is a configuration that maintains the watertightness of the packing by tightening the nut cap while frequently checking whether the fluid leaks, but the present invention has a cumbersome problem in management, but the present invention prevents strong packing and flow of the packing by the spring and pressure to prevent Since the pump efficiency is greatly improved and the service life is extended, there is no need to tighten the nut cap as often as before, and there is an advantage that maintenance is not necessary until the end of the packing life.
또한, 본 발명은 지지링과 부시와 스프링의 내경은 플런저의 외경보다 조금 크게 형성되어 있어서 플런저와 접촉하지 않게 되므로 마모와 마찰열 발생이 억제되고 플런저의 축동요가 방지되는 효과가 있으며, 스프링과 헤드케이스에 설치되는 스프링의 탄발력이 같거나 같은 수준이므로 평소 흡입밸브의 중립성이 유지되는 등의 효과가 있는 유용한 발명이다.In addition, the present invention has an inner diameter of the support ring, the bush and the spring is slightly larger than the outer diameter of the plunger, so that it does not come into contact with the plunger, so that wear and friction heat are suppressed and axial fluctuations of the plunger are prevented. Since the spring force of the spring installed in the case is the same or the same level, it is a useful invention having the effect of maintaining the neutrality of the usual suction valve.
