Changsha 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 the installation and calibration must be carefully carried out, not sloppy. 2, the installation of pump suction pipe 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, suction and discharge piping should be scaffolding. Pump is not allowed to withstand the load on the pipeline. 4, the location of the pump should be spacious enough to facilitate maintenance work. Installation order: 1, the unit on the foundation buried in the bolt, between the base and the foundation, 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 small) gap to be uniform, 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. In the process of testing the bearing temperature and vibration check as follows: 6, during the installation, in order to prevent debris falling into the machine, all the holes should be covered unit. 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. Changsha pump maintenance: the Changsha Pump Factory Changsha industrial pump long electric pump pump maintenance should pay attention to the following aspects: 1. Water corrosion of the pump, so the water-borne substances prohibited the use of pump vacuum, go to Room 1210 pump vacuum . 2. Contains a lot of solvent substances First remove most of the solvent in the oven, and then use a vacuum pump. 3. Use the vacuum pump in the correct sequence to prevent reverse suction. 4. After using the vacuum oven, be sure to do a good job of cleaning, vacuum cleaning oven glass. 5. Wipe the surface anti-rust oil. 6. Clear the governor cavity, injection pump cavity anti-rust oil, add the required grades of lubricating oil. 7. The anti-rust oil in the fuel pipeline should also be removed before use. Connect the fuel to the fuel injection pipe line and keep rotating the fuel injection pump camshaft until the oil-out valve is tightly closed to emit clean fuel. 8. Fuel selection is reasonable. 9. You must use the fuel labeled. The general use of No. 0 diesel in summer, winter use -10 light diesel oil. 10. The fuel used must be clean and contain no impurities or moisture.
