Specialty

Lower loads on shafting bearings and long operating life. Simple structure and stable performance. It is easy to maintain.

Have pressure ring of special structure and it could use the hydraulic oil of low flame. It could form the motor pump combination.

Instructions

1. The axis of the motor pump using the axis connecting shaft assembly, the parallelism error should be within 0.05mm, angle error is within 1 degree. It is recommended to use direct type oil pump motor.

2. Recommended hydraulic oil viscosity working pressure is less than 70kg/cm2, with 30-50 CST(ISOVg32) is proper.

3. The hydraulic oil continuous working temperature should be kept within 15-60℃. Please use heaters if below 15℃ and use the cooler over 60℃.

4. When new machine starts running, the motor should be started repeatedly in a no-pressure state to eliminate the air in the pump and suction oil. To ensure that the air in the system is eliminated, it can be operated continuously for 10 minutes under no load.

5. Pump oil level of suction port should not be higher than 1m.
