Description
Technical field:
The present invention relates to a kind of diaphragm type high pressure plunger pump.Be mainly used in high-pressure delivery, high-pressure wash, high-pressure delivery high viscosity liquid etc.
Background technique:
Present existing pump is generally independent plunger pump or diaphragm pump, or is diaphragm, plunger unipump.But its pressure is low, efficient is low, noise is big, be not easy to operation and maintenance.
Summary of the invention;
The objective of the invention is to overcome above-mentioned deficiency, the diaphragm type high pressure plunger pump of a kind of high pressure, high efficiency, low noise, easy operating and maintenance is provided.
The object of the present invention is achieved like this: a kind of diaphragm type high pressure plunger pump, comprise pump shaft, pump case, eccentric plunger is cut somebody's hair, plunger, plunger mat, spring, diaphragm, valve plate, valve and pump cover, the pump case back-end closure, uncovered and the stacked successively plunger mat of front end, valve plate and pump cover, pump shaft is inserted in the pump case, eccentric plunger push head device is on pump shaft, the plunger mat center is provided with the pump shaft seat, periphery is evenly equipped with plunger tube, the pump shaft front end places in the pump shaft seat, plunger places in the plunger tube, and diaphragm places the plunger tube front side, links to each other with the plunger front end, ring-type is evenly equipped with two groups of reverse one-way valves on the valve plate front-end face, be furnished with a plurality of chambers on the valve plate ear end face, chamber communicates with one-way valve, and diaphragm places the chamber rear side, the pump cover ear end face is provided with separated ring-type admission chamber and exhaust chamber, advance, exhaust chamber communicates with two groups of one-way valves on the valve plate respectively, offers liquid entering hole and liquid port on the pump cover front-end face, advances, liquid port, respectively with the advancing of pump cover rear end, exhaust chamber communicates.
The pump housing of the present invention is divided into two-part: fill the grease chamber of lubricant oil and the pump chamber of pressurized delivered liquid.Grease chamber and pump chamber separate with diaphragm.Do not have driver part in the pump chamber and produce the sealed member of friction.
Along with the rotation of pump shaft, eccentric plunger is cut somebody's hair and is promoted three plungers successively, increases the oil pressure in the plunger tube, and diaphragm is agitated towards the pump chamber direction.Meanwhile, the piston spring in other plunger tubes pushes back plunger, and diaphragm is led oil revolute chamber's direction again.
Liquid is sucked by the liquid entering hole at pump cover center, is divided into three by the cell one of valve plate, valve, valve pad and three diaphragm formations.The volume of cell is because the expansion that the to-and-fro motion of diaphragm does not stop and dwindling, and two of positive and negative installation groups of valves alternately open and close motion in the cell, and liquid is flowed towards certain direction, can be flowed by the liquid port on the pump cover again.
The present invention has following characteristics:
1, high pressure, high efficiency
In filling the grease chamber of lubricant oil, the turning power of motor is converted to energy pressure effectively, from low pressure to the high pressure, can obtain 85% high efficiency, reduces power consumption.
2, high-pressure delivery slurries
Because hydraulic chamber's (drive portion) is separated by diaphragm fully with pump chamber, drive unit can not be subjected to the damage of slurries, thus the long-term high-efficient operation of energy, and long service life.
3, low noise, low pulsation
Three plunger types structure is realized running up, in addition because the oil pressure actuated diaphragm can be controlled pulsation and maintenance low noise.
4, movability operation
Owing to do not need Sealing can avoid axle envelope fault, and need not exhale water to get final product self-priming.The rotation of pump shaft positive and negative direction all can guarantee normal liquor charging in addition.
5, be easy to safeguard
Need not pull down pump head can change diaphragm and valve, saves time.
