Hot water pipe pump troubleshooting

In our daily life, hot water pipe pump failure is everywhere, and some people will ask professionals to come over the maintenance staff, and some people just have the relevant knowledge, so encounter common problems, Can be handled by their own, not only save time, but also save money. The following is to talk about the hot water pipe pump troubleshooting it. Symptoms: 1, the pump is not water failure causes: 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. Remedy: 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, downtime, inspection, adjustment (water pipe or suction pipe with easy to use this phenomenon). f, reduce pipe corners, re-select the pump. 2, insufficient pump flow failure causes: 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. Remedy: 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 Fault causes: a, more than the rated flow. b, suction is too high. c, pump bearing wear. Remedy: a, adjust the flow, close the small outlet valve. b, reduce. c, replace the bearing. 4, noise vibration cause of the malfunction: a, pipe support instability. b, liquid mixed with gas. c, produce cavitation. d, bearing damage. e, the motor overload heating operation. Remedy: a, solid pipeline. b, improve suction pressure exhaust. c, reduce the degree of vacuum. d, replace the bearing. e, adjust press 5. 5, motor fever failure reasons: a, flow is too large, overload operation. b, rub rub. c, motor bearing damage. d, the voltage is insufficient. Remedy: a, off the small outlet valve. b, check and exclude. c, replace the bearing. d, regulator. 6, pump leakage causes of failure: a, mechanical seal wear. b, sand or cracked pump body. c, sealing surface is not flat. d, Loose mounting bolts. Remedy: a, replacement. b, welding repair or replacement. c, trimming. d, fastening. The above is some of the common faults and their removal methods, as the saying goes, ask people not as good as themselves, to master some of the common faults and their methods, follow-up in the course of use if you encounter a similar problem yourself to solve it, Why not do it?
