Description

로우터리 펌프Rotary pump

제1도는 본 고안의 단면도.1 is a cross-sectional view of the present invention.

제2도는 종래 펌프 단면도.2 is a cross-sectional view of a conventional pump.

본 고안은 로우터리 펌프의 측면에 압력실을 첨설하고 흡입실의 흡입측 방향에서 회전축을 삽도하므로서 고압 액체의 누출을 방지하고 토출실의 압력을 소망대로 감압할 수 있게 함을 목적한 로우터리 펌프에 관한 것이다.The present invention installs a pressure chamber on the side of the rotary pump and inserts a rotating shaft in the suction side of the suction chamber to prevent leakage of high pressure liquid and to reduce the pressure in the discharge chamber as desired. It is about.

종래에는 회전자(rotor)의 회전축을 흡입구의 반대측 방향의 커버를 관통되게 관착하고, 커버의 축공에는 팩킹을 삽착하여서 된 로우터리 펌프가 있었으나, 이것은 고속으로 회전되는 회전축의 마찰로 인해 팩킹이 쉬 마모되므로서 고압으로 토출되는 액체의 유속과 압력이 축공으로 누출되는 바람에 액체의 허실이 많았고 또 이것을 보수하기 위해서는 팩킹을 자주 교체해야 하므로 펌프의 작동을 간헐적으로 멈추어야만 했다. 또 종래에는 압력실이 없었으므로 필요한 압력을 얻기 위해서는 전동기의 회전수를 변환하므로서 대체적으로 조절하여 왔으나 필요 압력을 적절하게 얻기 지난하는 등 여러 가지의 결점을 지니고 있었다.Conventionally, there has been a rotary pump in which a rotating shaft of a rotor is inserted through a cover in a direction opposite to the inlet port and a packing is inserted into the shaft hole of the cover, which is easy to pack due to friction of the rotating shaft rotating at high speed. As the flow rate and pressure of the liquid discharged at high pressure due to abrasion leaked into the shaft hole, there was a lot of loss of liquid, and in order to repair it, the packing had to be frequently replaced, and the pump had to be stopped intermittently. In addition, since there is no pressure chamber in the related art, in order to obtain the required pressure, the motor has been generally adjusted by converting the rotation speed of the motor, but it has various disadvantages such as obtaining the required pressure properly.

본 고안은 이와 같은 점을 감안하여 로우터리 펌프의 측방에 압턴실을 첨설하고 회전축을 흡입실에 삽입함으로서 회전축의 축공에 하등의 압력을 받지 않게하여 누액을 방지하며 또한 압력실과 흡입실을 감압변으로 연결하고 압력실 상부는 공기실을 형성게 하므로서 토출 압력을 일정하게 유지할 수 있도록 하여 종래의 여러가지 결점을 일소한 것인데 첨부된 도면에 따라 상술하면 다음과 같다.In view of the above, the present invention installs an apton chamber on the side of the rotary pump and inserts the rotary shaft into the suction chamber to prevent leakage from being subjected to any pressure from the shaft hole of the rotary shaft. By connecting to the pressure chamber to form an air chamber to maintain a constant discharge pressure to eliminate the various drawbacks of the prior art according to the accompanying drawings as follows.

흡입관(1)과 흡입구(2)를 갖춘 흡입실(3)을 펌프(4)의 일면에 부착한 타면에 있어서 토출관(5)과 압출로(6)를 갖춘 압력실(7)을 침설하고 연결관(8)을 매개로 압출로(6)와 환수로(9)를 연결되게 한 흡입실(3)내에 펌프(4)의 회전축(10)을 구착하여서 되는 것이다.On the other side in which the suction chamber 3 having the suction pipe 1 and the suction port 2 is attached to one surface of the pump 4, the pressure chamber 7 having the discharge tube 5 and the extrusion path 6 is submerged. The rotary shaft 10 of the pump 4 is mounted in the suction chamber 3 in which the extrusion passage 6 and the return passage 9 are connected via the connecting pipe 8.

도면중 미설명부호 11은 배출구이며 12, 12′는 메탈이고 13은 회전자(14)를 회전축(10)에 고정시킨 키이며 15는 팩킹이고 16 16′ 16″ 16′″는 환상 팩킹이며 17은 압력계이며 18는 감압 밸브이다.In the drawings, reference numeral 11 denotes an outlet, 12, 12 'is a metal, 13 is a key fixing the rotor 14 to the rotating shaft 10, 15 is a packing, 16 16' 16 "16 '" is an annular packing 17 Is a pressure gauge and 18 is a pressure reducing valve.

그리고 제2도에서 표시한 종래의 펌프에 있어서 100은 흡입구이며 101은 회전자이고 102는 회전축이며 103은 토출실이고, 103′는 토출구이며 104는 커버이고 105는 축공이며 106은 팩킹이다.In the conventional pump shown in FIG. 2, 100 is a suction port, 101 is a rotor, 102 is a rotating shaft, 103 is a discharge chamber, 103 'is a discharge port, 104 is a cover, 105 is a shaft hole, and 106 is a packing.

종래는 제2도에서 표시한 바와 같이 흡입구(100)에서 흡입되는 액체가 토출되는 방향에서 회전자(101)의 회전축(102)를 토출실(103)의 개방부에 나착된 커버(104)의 축공(105)을 통해 관삽한 것이므로 이에 포삽된 팩킹(106)은 회전축(102)의 고속회전에 의하여 마모되어 생기는 축공(105) 둘레의 간격으로부터 토출 방향에 직행으로 밀려오는 거센 토출 압력을 받아 쉬이 액체가 누출되는 폐단이 있었다.Conventionally, as shown in FIG. 2, the cover 104 attached to the opening of the discharge chamber 103 has the rotary shaft 102 of the rotor 101 in the direction in which the liquid sucked from the suction port 100 is discharged. Since the packing 106 is inserted through the shaft hole 105, the packing 106 inserted into the shaft 106 receives a strong discharge pressure that is pushed straight in the discharge direction from the gap around the shaft hole 105 caused by the high speed rotation of the rotary shaft 102. There was a lung leak where the liquid leaked.

본 고안에 있어서는 기지한 로우터리 펌프(4)를 중심으로 그 일측면에는 흡입실(3)을, 타측면에는 압력실(7)을 각각 부설하고 회전자(14)의 회전축(10)을 토출관(5)이 부설된 압력실(7)과는 별도로 흡입실(3)내에 구착하므로서 흡입실(3)내에 흡입되는 액체의 압력은 항상 흡입구(2)를 통하여 펌프(4)의 회전자(14)에 흡입됨에 따라 회전축(10)의 고속 회전으로 인해 팩킹(15)이 마손되어도 기체 밖으로 액체가 누설되는 폐단을 보다 감소시킬 수 있는 것이다.In the present invention, the suction chamber 3 is provided on one side and the pressure chamber 7 on the other side of the rotary pump 4, and the rotary shaft 10 of the rotor 14 is discharged. The pressure of the liquid sucked in the suction chamber 3 is always mounted in the suction chamber 3 separately from the pressure chamber 7 in which the pipe 5 is installed. 14, even if the packing 15 is worn out due to the high speed rotation of the rotary shaft 10, it is possible to further reduce the closed end of the liquid leakage out of the gas.

이와 같은 본 고안은 회전축(10)의 삽통과는 독립되는 압력실(7)을 첨설하고 흡입되는 액체와 그 압력을 배출구(11)를 통해 유도하므로서 가능한 것인데 토출구(5)의 개폐로서 증감되는 압력실(7)의 압력은 연결간(8)을 통해 흡입실(3)로 압력이 이행되므로 감압 밸브(18)를 임의 조정하여 필요한 토출 압력 및 토출량을 간편하게 얻을 수 있게 된다.This invention is possible by adding a pressure chamber (7) independent of the insertion shaft of the rotary shaft (10) and inducing the suction and the pressure through the discharge port (11). Since the pressure of the chamber 7 is transferred to the suction chamber 3 through the connecting rod 8, the pressure reducing valve 18 can be arbitrarily adjusted to easily obtain the required discharge pressure and discharge amount.

이와 같이 본 고안에 의하면 압력실(7)의 첨설과 흡입실(3)에 회전축(10)을 축가(軸架)하므로서 액체의 누출을 막아 액체가 가지는 악취, 인체에 미치는 독성 및 화재의 위험을 예방할 수 있고 감압밸브(18) 및 압력실(7)의 공기실에 의해 필요한 토출압력 및 토출량을 일정하고 편리하게 얻을 수 있는 효과가 있다.As such, the present invention prevents the leakage of the liquid by adding the pressure chamber 7 and the rotating shaft 10 in the suction chamber 3 to prevent the odor of the liquid, the toxicity to the human body, and the risk of fire. It is possible to prevent and to obtain the required discharge pressure and discharge amount constantly and conveniently by the air chamber of the pressure reducing valve 18 and the pressure chamber 7.
