1. During installation, the concentricity tolerance between the pump shaft and the motor shaft 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 sturdy, rigid, and able to effectively absorb vibration.
2. During installation, it is recommended that the pump suction port be set to facilitate oil suction during startup.
3. Fixed pipelines, especially the inlet pipeline, must be sized according to the diameter, and a safety pressure relief valve must be installed in the system; the set pressure of the safety valve must not exceed the maximum pressure of the pump; the inlet pipeline must be strictly sealed to prevent leakage, and the oil return nozzle should be located 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 under no-load conditions as much as possible (preferably with the pump full of 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 from the pump inlet, with a recommended accuracy of 100 μm. A precision filter with an accuracy of 25 μm should be installed in the system. The oil cleanliness 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 turned on 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 at low temperatures, such as No. 32 oil.
9. After fixing the pump, manually rotate the pump shaft smoothly and flexibly.
