Improve fuel pressure, high-pressure injection, and achieve the best atomization results. The key use of hydraulic pump motors is as a power source for hydraulic assemblies such as jacks, upsets, knotters, and extruders.
The installation sequence of the hydraulic pump motor is as follows: During the installation of the hydraulic pump motor, in order to prevent debris from falling into the machine, all holes of the unit should be covered. Place the unit on the foundation buried with anchor bolts, and use a pair of wedges for correction between the base and the foundation.
Correct the concentricity of the pump shaft and the motor shaft. The allowable error is 0.1 mm above the outer circle of the coupling shaft; the gap between the two coupling planes should be 2 to 4 mm, and the gap should be even and allowable. The difference is 0.3 mm.
After connecting the pipeline and determining the rotation direction of the motor, connect the coupling again and check the concentricity of the shaft again. After the actual trial operation of the unit for 2 to 3 hours, make a final inspection. If there is no bad sign, the installation is deemed qualified. During the trial operation, check the temperature and vibration of the bearing as follows:
Loosen the coupling, place a level meter on the pump shaft and base of the electric oil pump, adjust the wedge pad to correct the unit level, and properly tighten the anchor bolts to prevent movement. In order to prevent debris in the pipeline from entering the pump, Baidu optimized the newly installed pipeline. A filter should be installed in the pump glue, and its useful section should be 2 to 3 times larger than the section of the suction pipe.
