Chemical pump assembly work

Chemical pump assembly work First, the preparation of chemical pump assembly ①, first check to confirm the chemical pump and motor in the process of disassembly or transport for damage, whether the link between the fasteners loose. ②, and then check the pump body for dirt and other dirt. ③, finally check the assembly tools and lifting machinery, and check the machine's foundation is solid. Second, the order of installation of chemical pump assembly ①, to find the level of the chemical pump installed base level horizontal position. ②, to be solidified after the foundation cement, the pump installed on the basis of the level has been reached, if not up to the level of the chemical pump shimmer level. Then use the concrete watering the base and anchor bolt holes. ③, until the cement after solidification, and then check the base and anchor bolts are loose, if loose, then continue to use concrete pouring to a solid. Tighten the nuts on the anchor bolts later. Once again, check and adjust the level of chemical pump units. ④, check the pump shaft and motor shaft concentricity. Standard: Measuring the outer circumference of the coupling up and down about the difference between the four directions can not exceed 0.1 mm, two couplings on the surface of the gap between the maximum and minimum clearance of 0.3 mm. ⑤, the pump suction pipe and discharge pipe should be provided with their own separate bracket, pipe weight can not be directly borne directly by the chemical pump, so as to avoid damage to the pump body. ⑥, adjust the pump shaft and motor rotation direction consistent. However, if the use of three-phase asynchronous motor, only three of the three leads in exchange for any position after the connection can be. ⑦, chemical pump installation height must NPSHr NPSHr as a standard, the pump installation position within the suction allowed as much as possible above the liquid level, so as to avoid cavitation.

Y-strainer is the transmission medium pipeline system indispensable to a filter device, Y-strainer is usually installed in the relief valve, relief valve, water level valve or other equipment imported to remove impurities in the media , To protect the normal use of valves and equipment. Y-strainer with advanced structure, resistance, easy to drain and so on. Y-strainer for medium can be water, oil and gas. General water network is 18 to 30 mesh, ventilation mesh for 10 to 100 mesh, oil network for the 100 ~ 480 mesh. Basket filter mainly by the takeover, charge, filter blue, flange, flange cover and fasteners and other components. As the liquid passes through the main tube into the filter blue, the solid impurity particles are blocked in the filter blue, and the clean fluid through the blue filter, the filter outlet.
