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 suction port should be set to facilitate oil suction during startup.
3. Secure the pipelines, especially the inlet pipeline, according to the diameter size, and install 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 and must not leak, and 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 installed or long-unused pump, air should be vented 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 of the tank, the suction height should be less than 500mm, the inlet should be located below the oil level of 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 50mm from the inlet of the pump, with a recommended precision of 100μm. A precision filter with a precision 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 a cold environment, the oil should be heated, and after starting the pump under no-load conditions, continuous no-load operation should be performed.
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 smoothly.
