ã€Asia Pump Network News】 gear pump in the chemical industry, the oil system is widely used. So, gear pump how to install? In the installation process should pay attention to what? The following small gear to bring you gear pump installation methods and precautions. Gear pump installation methods and precautions I. Gear pump (gear pump) installation method and order: 1. Place the unit on the foundation buried in the bolt, between the base and the base, with a pair of wedge pad Correction 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. During commissioning, check the temperature and vibration of the bearings as follows: 6. During the installation process, all the holes in the unit should be covered to prevent debris from falling into the machine. 7. In order to prevent the pipelines from entering the pump, it is advisable to install a filter on the newly installed pipeline, the effective cross section of which should be 2 to 3 times larger than that of the suction pipe. Two. Gear pump installation process should be noted: 1. Gear 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. Gear pump suction pipe installation height, length and diameter should meet the calculated value, and strive to be brief, reducing unnecessary losses (such as elbows, etc.); and to ensure that the pump does not exceed its allowance NPSH. 3. Gear pump suction and discharge piping should have a bracket. Pump is not allowed to withstand the load on the pipeline. 4. The place where the pipe pump is installed should be spacious enough to facilitate overhaul work. Through the above gear pump installation method, the installation sequence and precautions introduced, I believe everyone on the gear pump installation has a certain theoretical basis, the next is in the process of continuous summary. Hope that the above gear pump installation methods and precautions can bring you some help. Industry Internet (Xiamen) Technology Co., Ltd.
