2. Instructions

Oil selection and pollution control:

Before use, please ensure that the hydraulic oil is clean and pollution-free, and the pollution level should be controlled within NAS10 level.

The oil suction port must be installed with a tank filter of at least 100um (150 mesh), and the return oil line must be installed with a pipeline oil filter of less than 10um.

Installation precautions:

When installing the pump, the refueling port should be facing upwards, and rubber shock pads should be used as much as possible to reduce vibration.

Use flexible couplings to avoid stress caused by bending or thrust.

The allowable misalignment error is less than 0.1mm, and the maximum allowable angle error is less than 0.2°.

Operation and maintenance:

Check the oil quality regularly and replace the seriously contaminated hydraulic oil in time.

Pay attention to the pump body temperature to avoid overheating and performance degradation or damage.

Check the pump seals and connectors regularly to ensure they are tight and leak-free.
