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, 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 pipelines, especially the inlet pipeline, according to their diameter, and install a safety 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 leakage, and the oil return nozzle should be located below the liquid level.
4. Before starting the pump, check the inlet port, outlet port, and rotation direction. When operating the pump, for newly installed or pumps that have not been used for a long time, air should be released from the outlet port.
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 port should be located below the oil level in the tank, and the positive pressure at the inlet port 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 50mm above the bottom of the tank at the pump's inlet port, with a recommended accuracy of 100μm. A precision filter with an accuracy of 25μm 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 cold weather, the oil should be heated, and the pump should be turned on under no-load conditions, with continuous no-load operation.
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.
