Detailed YG vertical pipeline pump failure reasons and troubleshooting
YG vertical pipeline pump for transportation of gasoline, kerosene, diesel and other petroleum products, transportation medium temperature control in minus 20 degrees Celsius to 120 degrees Celsius range. Well, the actual use of the user process, due to improper use caused some problems, then, by Xiaobian explain to you the YG vertical pipeline pump failure reason and the corresponding troubleshooting. Detailed YG vertical pipe pump failure causes and troubleshooting 1. Failure phenomenon is the pump does not water, the possible reasons for the import and export valves are not open, out of the pipeline obstruction, the impeller flow path obstruction; motor running in the wrong direction, the motor phase loss The speed is very slow; the suction tube leaks; the pump is not filled with liquid, there is air in the pump chamber; import insufficient water supply, suction stroke is too high, leakage valve at the end of the valve; pipeline resistance is too large, pump improper selection, the corresponding exclusion method is to check , Remove the blockage; adjust the motor direction, tighten the motor wiring; tighten the sealing surface, remove the air; open the pump cover or open the exhaust valve, drain the air; stop checking and adjustment; reduce the pipe bend, re- , Of course, Shanghai Pump Factory pumps will not encounter pump selection improper problems, according to the actual use of the parameters of the customer requirements, and the plant's technical staff to select the most suitable type of supply. 2. In case of insufficient pump flow phenomenon, consider the pipeline, the pump impeller runner part of the blockage, scale deposition, the valve opening is insufficient; voltage is low; impeller wear, the corresponding exclusion method to remove obstruction, to re-adjust the valve opening; Regulator; replace the impeller. 3. There are three major causes of overheating during use of YG vertical pipe pumps, namely: Exceeds the rated flow use; Suction stroke is too high; pump bearing wear, the corresponding exclusion method: adjust the flow, close the small outlet valve; reduce Suction; replace the bearing. 4 appear pump noise and vibration phenomenon, consider: pipe support instability; liquid mixed with gas; produce cavitation; bearing damage, the corresponding method of exclusion: a solid pipeline; to enhance suction pressure, exhaust; reduce the degree of vacuum; Replace the bearing. 5 appears the phenomenon of motor heating, the fault causes are: flow is too large, overload operation; touch friction; motor bearing damage; voltage shortage, the corresponding exclusion method: off small outlet valve; check excluded; 6 in case of water pump leakage, two points to consider are: mechanical seal wear; sand or crack the pump body; sealing surface is not flat; loose mounting bolts, the corresponding exclusion: replacement of mechanical seals; welding repair or replacement; trimming; Tighten.
