Advantages and disadvantages of piston pump
Plunger pump is widely used in high-pressure, big flow, power systems and the flow needs to adjust the situation, such as planer, broaching machines, hydraulic machines, construction machinery and other widely used.
Piston with many forms.
1. Piston by piston arrangement and the movement in different directions, can be divided into radial piston and axial piston pump.
2. Piston pump according to the different ways of assignment can be divided into swash plate (straight shaft), and Cline.
The advantages of piston pump:
1. Parameter High: Rated high pressure, high speed, large power-driven pump
2. Efficiency, volumetric efficiency is 95% of the total efficiency of about 90%
3. Long life
4. Variable convenient form for
5 More unit power and light weight
6. Piston main components are compressive stress, strength of materials can be fully utilized
Piston shortcomings:
1. structure is more complex, parts are large,
2 . from poor absorption,
3. manufacturing process are higher, the costs are high,
4. oil pollution on the sensitive, require a higher filtering accuracy, use and maintenance requirements on the high.
