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 be subjected to 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's suction port should be easy to suck oil during startup.
3. Fix the pipeline, especially the oil inlet pipe, according to the diameter size, and assemble 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 oil inlet pipe must be strictly sealed, no oil leakage, and the return oil port should be lower than the liquid level.
4. Check the inlet and outlet and rotation direction before starting the pump. When operating the pump, if it is a newly fixed or long-unused pump, the outlet should be vented.
And start the pump as much as possible in a no-load state (preferably with the pump full of oil).
5. When the pump is fixed above the oil level of the oil tank, the suction height should be less than 500mm, the oil inlet should be lower than the oil level of the oil tank, and the positive pressure of the oil inlet is limited to within 0.03 MPa.
6. The oil should be kept clean; the pipelines and oil tank must be thoroughly cleaned. A filter with sufficient capacity should be fixed 50mm from the oil inlet of the pump, 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 operating 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 the pump should be started without load and run continuously without load.
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 evenly and flexibly.
