Agriculture machinery hydraulic piston pumps overload test
Hydraulic piston pumps basic information:
Hydraulic piston pumps have been around for decades, for one main reason: they don't require an external energy source - the force of fluid provides them with the energy they need. Pump is the variable displacement hydraulic pump that is with charge pump, the control way of variable displacement pump can be manual or hydraulic operated, and can simply control speed, direction and power of the output shaft.
Hydraulic piston pumps good advantage:
Advantages: high pressure resistance, high efficiency, large transmission power, wide speed range, long life, but piston pumps have strict requirements on the cleanliness of the working medium.
