1. During installation, the concentricity tolerance of the pump and motor must be less than 0.10mm (TIR), the maximum allowable angular error must be less than 0.2 degrees, and a flexible coupling must be used; 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 suction port of the pump 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 assembled 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 and must not leak; the oil return nozzle should be located below the liquid level.
4. Check the inlet, outlet, and rotation direction before starting the pump. When operating the pump, if it is a newly fixed or long-unused pump, air should be released from the outlet.
And start the pump as much as possible under no-load conditions (preferably with oil in the pump).
5. When the pump is fixed above the oil surface of the tank, the suction height should be less than 500mm, the inlet should be located below the oil surface of 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. A filter with sufficient capacity should be fixed at the inlet of the pump, 50mm from the bottom of the tank, and a precision of 100μm is recommended. A precision filter with a precision of 25μm should be assembled in the system. The cleanliness of the oil should be within NAS12.
7. The working temperature of the oil should be controlled between 15℃ and 55℃. If the pump is started in cold weather, the oil should be heated, and after the pump is started without load, it should be run continuously without load.
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.
