The working principle of the plunger pump is through the plunger in the cylinder piston cylinder constantly reciprocating motion, resulting in changes in the sealing cylinder volume changes caused by the pressure difference and the fluid medium to work . Change the working stroke of the plunger can control the size of the plunger pump flow. Piston pump hydraulic and pneumatic transmission is an important working parts. Knowing the type of plunger pump is very important for the choice of product. What are the types of plunger pump Next, will introduce several types of plunger pump related information: 1, axial piston pump: axial piston pump piston or plunger reciprocating direction and the central axis of the cylinder parallel to the column Plug the pump. Axial piston pump is the use of the plunger parallel to the shaft reciprocating motion in the plunger hole volume changes to work. Due to the plunger and plunger hole are round parts, machining can achieve high precision with the volume of high efficiency, smooth operation, flow uniformity, low noise, high working pressure, but the hydraulic oil pollution More sensitive, the structure is more complex, higher cost. 2, the straight shaft swash plate piston pump: Straight shaft swash plate piston pump is divided into two types of pressure supply type and self-suction type. Most of the pressure supply type hydraulic pump with air pressure tank, there are hydraulic pump itself with a charge pump to the hydraulic pump inlet to provide pressure oil. Self-priming oil pump self-priming oil capacity, no external oil supply. By hydraulic pressure oil tank, each time you start the machine, you must wait for the hydraulic pressure box to reach the use of air pressure before operating machinery. If the pressure of the hydraulic tank is low, the machine will be started, which will cause pull-off phenomenon in the hydraulic pump and the slippery whip, which will cause abnormal wear of the return plate and the pressure plate in the pump body. 3, radial piston pump: radial piston pump can be divided into the valve with the flow and shaft with two major categories. Valve distribution radial piston pump has the disadvantage of high failure rate and low efficiency. The international development of the 70,80 generation shaft radial flow radial piston pump to overcome the valve with radial piston pump deficiencies. Due to the structural features of the radial pump, the axial-flow radial piston pump is more resistant to impact than the axial piston pump, has a long service life and high control precision. Variable stroke Short pump variable is variable piston and limit plunger under the action of changing the eccentricity of the stator to achieve, and set the maximum eccentricity of 5-9mm (depending on displacement size), the variable stroke is very short . The variable mechanism is designed for high-pressure operation and is controlled by a control valve. Therefore, the pump response speed. The radial structure design overcomes the problem of partial wear of the axial piston pump slipper. Its anti-impact ability is greatly improved. 4, hydraulic piston pump: Hydraulic piston pump by hydraulic pressure hydraulic tank, each time you start the machine, you must wait for the hydraulic pressure tank to reach the use of pressure, to operate the machine. Straight shaft swash plate piston pump is divided into two types of self-suction oil pressure type. Most of the pressure supply type hydraulic pump with air pressure tank, there are hydraulic pump itself with a charge pump to the hydraulic pump inlet to provide pressure oil. Self-priming oil pump self-priming oil capacity, no external oil supply. For self-priming piston pumps, the fluid in the hydraulic tank should not be lower than the lower limit of the oil standard, and a sufficient amount of hydraulic oil should be maintained. The higher the cleanliness of the hydraulic fluid, the longer the life of the hydraulic pump. Since the 21st century, great changes have taken place in science and technology and economy in our country. In particular, in the past 20 years, all walks of life have been flourishing. Especially in the industrial, construction, petroleum, chemical and other industries, have made great progress. The demand for pumps in these industries is very special. Research on pumps has now become an important part of our economic development.
