Construction machinery mixer hydraulic pumps hydraulic motors
Mixer hydraulic pumps hydraulic motors basic information:
Hydraulic pumps could produce hydraulic through tubing to the hydraulic motor, hydraulic motor to convert hydraulic energy into kinetic energy and through reducer slow down and increase torque, transfer to the mixing tank, by adjusting the servo controller angle of hydraulic pump so as to realize reversing and speed of the drum, in order to realize concrete loading, mixing, stirring, discharging and other operations.
PV22 hydraulic pumps and MF22 hydraulic motors performance and characteristics:
1. High efficiency, high pressure, big displacement design meets the demands of harsh work conditions for mixer truck.
2. Has swash plate structure.
3. Be suitable for closed-loop circuit system of mixer truck.
4. Manual servo and hydraulic variable control mode.
5. PV22 variable displacement hydraulic pumps with a charging oil pump.
6. MF22 fixed displacement hydraulic motors.

Mixer hydraulic pump advantages:
1. High working pressure: due to easy processing of plunger and
cylinder hole, dimensional accuracy and surface quality can meet
high requirements, so high precision, small oil leakage, high
volume efficiency, high working pressure can be achieved.
2. Large flow range.
3. change the stroke of the plunger can change the flow, easy to
make a variety of variable type.
Hydraulic oil notice of hydraulic pumps hydraulic motors:
Hydraulic system pollution will affect the normal operation of the
mixer truck at any time, and affect the service life of hydraulic
pumps and hydraulic motors, serious damage to the pump and motor,
so it is very important for the hydraulic system.
Oil change and oil filter replacement:
1. 500 working hours for first run.
2. Replace every 1500 working hours from now on, but at least once
a year.
3. Note: When changing oil, replace hydraulic filter element at the
same time.
