1. Oil pump installation instructions

(1) Preparation before installation

Before installing a 20V oil pump, please ensure the following points:

The models and specifications of oil pumps and their accessories are matched to your needs.

The installation environment should be clean and free of debris and dust.

The installation location of the oil pump should be convenient for maintenance and inspection.

(2) Installation steps

Positioning and installation:

Use the dowel pins to properly position the oil distribution plate and stator.

Ensure that the blades, rotors, oil distribution plates and other components are installed in the correct direction and not upside down.

The suction area on the inner surface of the stator is prone to wear and tear. If necessary, it can be installed overturned to extend its service life.

Connect the pipes:

According to the inlet and outlet positions of the oil pump, correctly connect the oil suction pipe and the oil pressure pipe.

Ensure that the pipes are tightly connected and there is no leakage.

Electrical connection:

According to the electrical requirements of the oil pump, correctly connect the power line and control line.

Ensure that the electrical connection is safe and reliable, without short circuit and leakage.

Inspection and debugging:

After the installation is completed, conduct a no-load test run of the oil pump to check whether it runs smoothly and whether there are any abnormal sounds.

Adjust the flow rate, pressure and other parameters of the oil pump as needed.
