Testing and specialized equipment: Small and medium-sized hydraulic test benches, laboratory simulation loading equipment. Relying on their pressure regulation accuracy, the accuracy of test data is guaranteed.
Installation and usage methods
Installation preparation: The installation surface must be flat and clean, with burrs and impurities removed. Before installation, inject the appropriate hydraulic oil into the pump cavity to prevent dry grinding during startup. An elastic coupling is selected to connect the motor and the pump shaft, ensuring that the coaxiality deviation does not exceed 0.05mm.
Pipeline connection: The diameter of the oil suction pipe should match the oil suction requirements of the pump, and the oil suction flow rate should be controlled within 1m/s to avoid cavitation caused by insufficient oil suction. Connect the inlet and outlet oil pipes according to the oil port markings. When sealing the interfaces, select suitable sealing parts to prevent leakage.
Start-up and debugging: After confirming the correct rotation direction by briefly pressing the motor, run it at a low speed of 300-500 RPM without load for 5-10 minutes. Gradually increase the pressure to the rated pressure, and run stably for 2 to 3 minutes at each stage. Monitor for any abnormal sounds, leakage, etc.
Precautions
Oil management: It is strictly prohibited to mix different types of hydraulic oil. Priority should be given to using the recommended mineral oil or the suitable fire-resistant and flame-retardant hydraulic oil. The oil temperature should be controlled between -20 ℃ and 80℃. High temperature will accelerate the aging of sealing parts, while low temperature can easily lead to an increase in viscosity and affect the start-up.
Pressure and speed control: Avoid long-term operation at a peak pressure of 420bar. It is recommended to install a relief valve for dual protection. The rotational speed must not exceed the rated value to prevent excessive wear of internal components due to high-speed operation.
Regular maintenance: A 10μm precision filter should be installed at the oil suction port, and the filter element should be inspected or replaced every 1000 to 1500 hours. Seals should be replaced every 2,000 to 3,000 hours. Under harsh working conditions, the replacement cycle should be shortened.
Shutdown and maintenance: Before long-term shutdown, it is necessary to run it unloaded for 5 minutes to drain the high-pressure oil. When conducting maintenance, the system pressure must be released first. It is strictly prohibited to directly strike the pump body or pump shaft to avoid damaging the precision components.
