Abstract
The utility model relates to a corrosion and sand resistance diaphragm type pump, mainly comprising an upper box body, a one-way valve, a diaphragm, a buffer tank, a lower box body, a plunger pump, etc. The diaphragm is arranged between the upper box body and the lower box body through pressing. The utility model uses a transmission fluid to transmit the power of the plunger pump to the diaphragm, inhales and discharges the conveyed medium through movement of the diaphragm, and the opening and closing of the conveyed medium. The direct contact between the plunger pump and the conveying liquid with corrosion or sand can be avoided, so the corrosion and sand resistance function can be realized. In this way, the service life of the plunger pump is extended. The utility model is suitable for conveying the fluid with higher pressure, strong corrosion or sand in petroleum industry, coal industry, chemical industry, etc.
Description
The utility model is a kind of high pressure membrane pump of carrying strong corrosive media or containing the silt fluid.
At present, in petroleum industry, in the operations such as produced-water reinjection, acidifying, pressure break, profile control, the corrosion of high-pressure plunger pump and wearing and tearing are very serious, several subjobs such as high-pressure plunger pump that is worth surplus in the of 40,000 yuan is acidified, pressure break, what just be worn or corrode is done for, sometimes the also intact not operation of a bite well in pairs of pump, this has not only caused enormous economic loss, has also influenced normally carrying out of producing simultaneously.In this year, some high-pressure plunger pump has been carried out surperficial anticorrosion with painting with Shengli Oil Field and hardness is handled, and has prolonged its working life to a certain extent, but fails to solve on mechanism the wearing and tearing and the etching problem of high-pressure plunger pump at all.
The purpose of this utility model is a kind of anticorrosion sand prevention high pressure membrane pump of design, is full of the transmission fluid with certain viscosity and good lubrication effect in the pump housing, with a fatigue proof diaphragm transmission fluid be transferred medium and separate.Be in operation, plunger pump by the to-and-fro motion of transmission fluid driven diaphragm to suck, to discharge Korrosionsmedium or contain the silt medium, thereby guaranteed that plunger pump works under the situation of good lubrication, improved its operating conditions greatly, reached to reduce to corrode and reduced the purpose that wearing and tearing prolong its working life.
The utility model is achieved in that between upper box and lower box and press-fits diaphragm, and two one-way valves are housed on the upper box, spring seat on the upper box, be pressed on the one-way valve, upper box is equipped with the product flange by the external knock out drum of flange on knock out drum; Lower box is connected with plunger pump by flange, is full of transmission fluid between lower box and post match pump, and screw plug is housed on lower box.
Describe in detail with reference to the accompanying drawings:
Accompanying drawing 1 is a structure principle chart of the present utility model.
With reference to accompanying drawing 1, one-way valve (3) and one-way valve (6) are housed on upper box (1), press-fit diaphragm (4) between upper box (1) and lower box (10), lower box (10) is connected with plunger pump (12) by flange (11), be full of transmission fluid (16) between lower box (10) and plunger pump (12), knock out drum (8) is connected with upper box with flange (15) by flange (7) respectively with knock out drum (13); Spring (2) seat is pressed on the one-way valve (3) on upper box (1), and spring (5) seat is pressed on the one-way valve (6) on upper box (1); Suction flange (9) is housed on the knock out drum (8), outlet(discharge) flange (14) is housed on the knock out drum (10), screw plug (17) is housed on lower box (10).
When this pump work, plunger pump (12) is by transmission fluid (16) driven diaphragm (4) to-and-fro motion, when diaphragm moves downward under the transmission fluid effect, pressure reduces in the upper box (1), one-way valve (3) is closed, one-way valve (6) is opened, and is transferred medium and enters upper box by knock out drum (8) through flange (7) and one-way valve (6); When diaphragm moves upward under the transmission fluid effect, pressure rises in the upper box (1), overcoming spring (2) opens one-way valve (3) to the active force of one-way valve (3), medium is forced out upper box (1), send into the fed sheet of a media pipeline by flange (15) through knock out drum (13) and flange (14), then, diaphragm moves downward the repetition said process once more under the transmission fluid effect.Medium is constantly sucked and is discharged upper box.For the double-action plunger pump of present industrial use, can adopt the membrane pump device parallel operation of two covers except that plunger pump (12).
Because this device has avoided plunger pump with aggressive medium or contain the direct of silt medium and contact, and has therefore prolonged the plunger pump life-span greatly, functional reliability also improves greatly.This anticorrosion sand prevention pump easily damaged parts is diaphragm and one-way valve, and its replacing is compared will save many with rehabilitation expense with present plunger pump rehabilitation expense.This pump is carried the elevated pressures severe corrosive applicable to industry such as oil, coal, chemical industry or is contained the fluid of silt.
Claims (4)
1, a kind of by upper box, lower box, transmission fluid, diaphragm, one-way valve, spring, knock out drum, the anticorrosion sand prevention membrane pump that plunger pump etc. are formed, it is characterized in that on upper box (1), being equipped with one-way valve (3) and one-way valve (6), press-fit diaphragm (4) between upper box (1) and lower box (10), lower box (10) is connected with plunger pump (12) by flange (11), be full of transmission fluid (16) between lower box (10) and plunger pump (12), knock out drum (8) is connected with upper box (1) with flange (15) by flange (7) respectively with knock out drum (13).
2, anticorrosion sand prevention membrane pump according to claim 1 is characterized in that spring (2) seat on upper box (1), is pressed on the one-way valve (3), and spring (5) seat is pressed on the one-way valve (6) on upper box (1).
3, anticorrosion sand prevention membrane pump according to claim 1 is characterized in that suction flange (9) is housed on the knock out drum (8), and outlet(discharge) flange (14) is housed on the knock out drum (13).
4, anticorrosion sand prevention membrane pump according to claim 1 is characterized in that being equipped with screw plug (17) on lower box (10).
