Improving fuel pressure, high-pressure injection, and achieving the best atomization results, the key use of hydraulic pump motors is as a power source for hydraulic assemblies such as jacks, upsetting heads, tying machines, extruders, etc.The installation sequence of hydraulic pump motor is as follows: During the installation of hydraulic pump motor, in order to avoid debris falling into the machine, all holes of the unit should be covered. Place the unit on a foundation with embedded anchor bolts, and use paired wedge pads between the base and foundation for calibration.Correct the concentricity of the pump shaft and motor shaft, with a permissible error of 0.1 millimeters above the outer circle of the coupling road; The gap between the two coupling planes should be ensured to be 2-4 millimeters, and the gap should be uniform with a tolerance of 0.3 millimeters for small pumps.After connecting the pipeline and determining the direction of motor rotation, connect the coupling again and verify the concentricity of the shaft. After 2-3 hours of actual trial operation of the unit, conduct a final inspection. If there are no adverse signs, the installation is considered qualified. During the trial operation, check the temperature and vibration of the bearings as follows:Loosen the coupling shaft and place it on the pump shaft and base of the electric oil pump with a spirit level. Adjust the wedge pad to calibrate the level of the unit, and tighten the anchor bolts appropriately to prevent movement. To prevent debris from entering the pump in the pipeline, Baidu optimization should be applied to newly installed pipelines. A filter should be installed on the pump glue, and its effective cross-section should be 2-3 times larger than the cross-section of the suction pipe.
