Should prevent inhalation of solid pump body and other debris, for the suction line should be set filters. Effective filter area over the water should be 2-3 times the cross-section of the suction pipe, the filter should be checked regularly. D, the suction and discharge piping should have its own stand, the body itself does not allow the pipeline to withstand the load. 5, pump installation 80ZX50-32 pump, should make static grounding resistance pumps and pipeline reaches its requirements. 6, the installation should strictly check the pump casing and tubing with or without stones, iron ore and other debris. 7, the correction pump coupling and installation space and coaxial motor action couplings, the misalignment tolerance of 0.1mm. Pump shaft and motor shaft height difference may be copper or iron pad adjustment at the end of the foot. 8, in the actual operation of the unit for 3-4 hours after the final inspection, if no adverse phenomenon, the Lord has been properly installed in the test run should check the shaft. 9, the pump bearing body where a cooling water for cooling chamber device with the hole for fitting hose or plastic tube of 12 with 80ZX40-22 pump, its thread size M12x1.75. 10, in the discharge piping of the pump, such as a check valve fitted in the process of self-priming the pump can not smoothly exhaust gas, should be added at the outlet of the pump connected to exhaust pipes and valves. The suction pump is a common pump south. The principle is the use of water velocity momentum, driven impeller pump impeller pump water above the riverbank. This pump can pump water thrown into the river, but must be strong currents, or where there is a gap. Self-priming centrifugal pumps and general different. Centrifugal pump before work, pump and tank filled with water inlet pipe must line into 80ZX35-13 vacuum pump, when the rapid rotation of the impeller blades to promote water soon, the rotation of the water under the effect of centrifugal force from impeller flew, the water pump is thrown, the central part of the impeller to form a vacuum region. Suwon water at atmospheric pressure (or pressure) in the role of the inlet pressure to the inside through the pipe network. This endless cycle, you can achieve continuous pumping. Self-priming pump is not needed irrigation water, which is the origin of self-priming pump. Self-priming pump priming principle: Due to the special design of the pump casing. Sealing performance than the average high centrifugal pumps, electrical outage and after the water pump housing does not automatically emptying, high-speed rotary motor driven turbine, quickly make a negative pressure (vacuum) pump. The use of atmospheric pressure to the pump casing, and then centrifuged head. Therefore, pump suction lift no more than one atmosphere, about 11M.
