1. Matters needing attention during installation of oil pump:

　　

　　 1. The place where the oil pump is installed should be spacious enough to facilitate maintenance work.

　　

　　2. The quality of the installation of the oil pump has a very important impact on the smooth operation and service life of the pump. Therefore, the installation and calibration work must be carried out carefully and not rashly.

　　

　　3. The installation height, length and pipe diameter of the suction pipe of the oil pump should meet the calculated value, strive to be short, reduce unnecessary losses (such as elbows, etc.); and ensure that the pump does not exceed its allowable cavitation allowance when it is working.

　　

　　4. The suction and discharge pipelines of the oil pump should have brackets. The pump is not allowed to bear the load of the pipeline.

　　

　　 2. How to install the oil pump

　　

　　 1. In order to prevent debris in the pipeline from entering the pump, a filter should be installed in the pump glue for the newly installed pipeline, and the section should be 2 to 3 times larger than the section of the suction pipe.

　　

　　2. Place the unit on the foundation buried with anchor bolts, and use a pair of wedge pads for correction between the base and the foundation.

　　

　　3. Check the unit after 2 to 3 hours of actual trial operation. If there are no defects, the installation is deemed qualified. During the trial operation, check the temperature and vibration of the bearing as follows:

　　

　　4. Loosen the coupling, place a level on the pump shaft and the base separately, adjust the wedge pad to correct the unit level, and properly tighten the anchor bolts to prevent it from moving.

　　

5. Correct the concentricity of the pump shaft and the motor shaft. On the outer circle of the coupling shaft, the allowable deviation is 0.1 mm; the gap between the two coupling planes should be 2 to 4 mm, and the gap should be even. The tolerance is 0.3 mm.

　　

　　 6. After connecting the pipeline and determining the direction of rotation of the motor, connect the coupling again and check the concentricity of the shaft again.

　　

　　 7. During the installation process, in order to prevent debris from falling into the machine, the holes of the unit should be covered.
