2017 New Horizontal Pipeline Pump Usage and Analysis of Common Problems

Horizontal pipe pump uses a lot to high-rise water is the most common, in addition, it is also commonly used in the boiler or the transfer of liquid material similar to water. In the use of horizontal pipe pump, often there will be some failures, then how to deal with these failures do, please check with Xiaobian! 2017 latest horizontal pipe pump use and common problems analysis (A) of the horizontal pipe pump The main purpose 1, horizontal water centrifugal pump for conveying water and physical and chemical properties similar to other liquids used for water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden sprinkler, fire pressurization, long distance transport , HVAC refrigeration cycle, bathroom and other heating and cooling water circulation and equipment supporting the use of temperature t ≤ 80 ℃. 2, horizontal hot water pump is widely used in: metallurgy, chemicals, textiles, paper and hotels and restaurants boilers and other hot water cycle pressurized heating and urban heating system, iswr-type use temperature t ≤ 120 ℃. 3, horizontal chemical pump, for the delivery of non-solid particles, corrosive, viscosity similar to water, suitable for petroleum, chemical, metallurgical, power, paper, food and pharmaceutical and synthetic fiber and other departments, the use of temperature of -20 ℃ ~ + 120 ℃. 4, ISWB horizontal pipeline pump, for the delivery of gasoline, kerosene, diesel and other oil products or flammable and explosive liquids, medium temperature is -20 ~ + 120 ℃. (B) of the horizontal pipe pump fault phenomenon troubleshooting reasons 1, the pump does not water a, import and export valves are not open, out of the pipeline blockage, runner blockage. b, the motor is running in the wrong direction, the motor phase loss is very slow. c, suction tube leakage. d, the pump is not filled with liquid, the pump cavity with air. e, imported insufficient water supply, suction stroke is too high, the valve leaks. f, pipe resistance is too large, improper pump selection. a, check, remove the blockage. b, adjust the motor direction, tighten the motor wiring. c, tighten the sealing surface, remove leakage. d, filled with liquid and open the exhaust valve, drain the air. e, stop, check, adjust. f, reduce pipe corners, re-select the pump. 2, insufficient pump flow a, first press 1. Cause check. b, pipes, pump impeller blockage, scale deposition, the valve opening is not enough. c, the voltage is low. d, impeller wear. a, first press 1. exclude. b, remove the blockage, readjust the valve opening. c, regulator. d, replace the impeller. 3, the power is too large a, more than the rated flow. b, suction is too high. c, pump bearing wear. a, adjust the flow, off the small outlet valve. b, reduce. c, replace the bearing. 4, noise vibration a, unstable pipe support. b, liquid mixed with gas. c, produce cavitation. d, bearing damage. e, the motor overload heating operation. a, a solid pipeline. b, improve suction pressure exhaust. c, reduce the degree of vacuum. d, replace the bearing. e, adjust press 5. 5, the motor heat a, flow is too large, overload operation. b, rub rub. c, motor bearing damage. d, the voltage is insufficient. a, off the small outlet valve. b, check and exclude. c, replace the bearing. d, regulator. 6, pump leaking a, mechanical seal wear. b, sand or cracked pump body. c, sealing surface is not flat. d, Loose mounting bolts. a, replace. b, welding repair or replacement. c, trimming. d, fastening.
