First, the installation method and sequence of the pump: 1, the unit on the foundation buried in the bolt, between the base and the base, with a pair of wedge pad with calibration. 2, release the coupling large, respectively, with the spirit level on the pump shaft and base, by adjusting the wedge pad, the unit level correction, appropriate tightening anchor bolts to prevent ambulation. 3, the correction of the concentricity of the pump shaft and the motor shaft, the outer diameter of the shaft in the joint, allowing the deviation of 0.1 mm; two coupling plane clearance should be guaranteed 2 to 4 mm, (small pump to take a small value) Tolerance of 0.3 mm. 4, pick up the pipeline and determine the direction of motor rotation, then connect the coupling, and then check the concentric ax again axis. 5, the actual test run in the unit after 2 to 3 hours for the final inspection, if no bad phenomenon, 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, to prevent debris in the pipeline into the pump, the newly installed pipeline, the pump should be installed gel filter, the effective cross-section should be greater than 2 to 3 times the suction tube cross section. Imported pump Second, the process of installing the pump should pay attention to the matter: 1, the installation of the pump is good or bad, the smooth operation of the pump and the service life has a very important impact, so the installation and calibration work 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 allowance NPSH. 3, the pump suction and discharge pipe should have a bracket. Pump is not allowed to withstand the load on the pipeline. 4, the location of the installation of pumps should be spacious enough to facilitate maintenance work. This article Keywords: oil pump
