1. During installation, the concentricity tolerance between the pump shaft and the motor must be less than 0.10 mm (TIR), and the maximum allowable angular error must be less than 0.2 degrees. When using a flexible coupling, the pump shaft must not bear radial and axial loads; the bracket must be strong and rigid, and able to fully absorb vibration.
2. During installation, it is recommended that the pump suction port be set to facilitate oil suction during startup.
3. Secure the pipeline, especially the inlet pipe, according to the diameter size, and install a safety pressure relief valve in the system; the set pressure of the safety valve must not exceed the maximum pressure of the pump; the inlet pipe must be strictly sealed to prevent oil leakage, and the return oil nozzle should be located below the liquid level.
4. Before starting the pump, check the inlet, outlet, and rotation direction. When operating the pump, if it is newly installed or has not been used for a long time, air should be released from the outlet.
And start the pump as much as possible under no-load conditions (preferably with the pump filled with oil).
5. When the pump is fixed above the oil level in the tank, the suction height should be less than 500 mm, the inlet should be located below the oil level in the tank, and the positive pressure at the inlet should be limited to within 0.03 MPa.
6. The oil should be kept clean; the pipelines and tank must be thoroughly cleaned. Install a filter with sufficient capacity 50 mm above the pump inlet, and a precision of 100 μm is recommended. A precision filter with a precision of 25 μm should be installed in the system. The cleanliness of the oil should be within NAS12.
7. The operating temperature of the oil should be controlled between 15℃ and 55℃. If starting the pump in a cold environment, the oil should be heated, and the pump should be started under no-load conditions and run continuously under no-load conditions.
8. Pay attention to the viscosity and quality of the oil. It is recommended to use anti-wear hydraulic oil, such as No. 32 oil, at low temperatures.
9. After fixing the pump, manually rotate the pump shaft evenly and flexibly.
