6D16 ME074345 High Pressure Oil Pump For MITSUBISHI

Installation instructions

1. The installation of the pump has a very important impact on the stable operation and service life of the pump. Therefore, the installation and calibration must be carried out carefully and no haste is allowed.

2. The installation height, length and diameter of the suction pipe of the pump shall meet the calculated value and try to be brief to reduce unnecessary losses (such as elbows); And ensure that the allowable NPSH of the pump is not exceeded during operation.

3. Suction and discharge lines shall have brackets. The pump is not allowed to bear the load of the pipeline.

4. The place where the pump is installed shall be spacious enough to facilitate maintenance.

1. Place the unit on the foundation with embedded anchor bolts, and use pairs of wedge pads between the base and the foundation for correction.

2. Loosen the coupling shaft, place it on the pump shaft and the base with a level gauge, adjust the wedge pad to correct the level of the unit, and properly tighten the anchor bolts to prevent moving.

3. Correct the concentricity of pump shaft and motor shaft, and the allowable deviation is 0.1mm on the outer circle of coupling road; The clearance between the two coupling planes shall be 2-4 mm (the smaller value is taken for the small pump), and the clearance shall be uniform with a tolerance of 0.3 mm.

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

5. After the actual test run of the unit for 2-3 hours, the final inspection shall be conducted. If there is no adverse phenomenon, the installation is considered to be qualified. During the test run, check the temperature and vibration of the bearing as follows:

6. In order to prevent sundries from falling into the machine during installation, all holes of the unit shall be covered.

7. In order to prevent sundries in the pipeline from entering the pump, a filter shall be installed on the pump rubber of the newly installed pipeline, and its effective section shall be 2-3 times larger than that of the suction pipe.
