Pump mechanical installation instructions

Pump installation instructions:
1. Pump installation is good or bad, the smooth operation of the pump and the service life has a very important impact, so installation and calibration must be carefully carried out, not sloppy.
2. Pump suction pipe installation height, length and diameter should meet the calculated value, and strive to be brief, reduce unnecessary losses (such as elbows, etc.); And to ensure that the pump does not exceed its allowable NPSH.
3. Suction and discharge lines should have brackets. Pump is not allowed to withstand the load on the pipeline.
4. The location of the pump should be spacious enough to facilitate overhaul work.
Installation order:
1. The unit is placed on the foundation buried bolt, between the base and the base, with a pair of wedge pad for calibration purposes.
2. Loosen the large couplings, respectively, with the spirit level on the pump shaft and the base, by adjusting the wedge pad, the unit level correction, appropriate tighten the anchor bolts to prevent ambulation.
3. To adjust the concentricity of the pump shaft and the motor shaft, allow the deviation of 0.1 mm on the outer circle of the coupling road; the gap between the two coupling planes should be 2 to 4 mm, and the gap should be uniform, Tolerance of 0.3 mm.
4. After connecting the pipeline and determining the direction of rotation of the motor, connect the coupling again and check the concentric rings of the shaft again.
5. In the actual test run 2 to 3 hours after the unit for the final inspection, if no adverse phenomena, then that the installation of qualified. Check the temperature and vibration of the bearing during commissioning as follows:
6. In the installation process, in order to prevent debris falling into the machine, all the holes of the unit should be covered.
7. In order to prevent the pipelines from entering the pump, it is advisable to install a filter on the newly installed pipeline, which should have an effective cross section of 2 to 3 times the cross section of the suction pipe.
