1. During installation, the concentricity tolerance of the pump and motor shafts must be less than 0.10mm (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 sturdy, rigid, and able to fully absorb vibrations.
2. During installation, it is recommended that the pump's suction port be conveniently positioned for oil suction during startup.
3. Secure the pipeline, especially the inlet pipe, according to the size of the diameter, and assemble a safety pressure relief valve in the system; the adjustment 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 below the liquid level.
4. Before starting the pump, check the inlet, outlet, and direction of rotation. When operating the pump, if it is newly fixed 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 500mm, the inlet should be below the oil level in the tank, and the positive pressure of 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 of sufficient capacity 50mm from the pump inlet, with a recommended accuracy of 100μm. A precision filter with an accuracy of 25μm should be assembled 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 the pump is started in a cold environment, the oil should be heated, and after the pump is turned on under no-load conditions, it should continue to run 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 smoothly and flexibly.
