FRP centrifugal pump failure reasons and troubleshooting: failure phenomenon troubleshooting reasons 1, the pump does not water a, import and export valves are not open, out of the pipeline blocked, flow impeller 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, 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 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.
Angle valve
Angle valve used in every place if need install faucets. It is a fitting, which connect between water plumbing and faucet`s flexible hose. Most of these made of Brass and chrome finished. Some made of stainless steel. Ceramic cartridge, quality can guarantee ten years no leakage water and no rusty.
