Detailed explanation of the causes and troubleshooting of YG vertical pipeline oil pump

YG vertical pipeline oil pump is suitable for conveying petroleum products such as gasoline, kerosene and diesel. The temperature of the conveying medium is controlled within the range of minus 20 degrees Celsius to 120 degrees Celsius. Then, in the process of the user's actual use, due to improper use caused by some problems, next, the Shanghai Yi pump pump industry for you to explain the YG vertical pipeline oil pump failure reasons and the corresponding troubleshooting methods.

1. The phenomenon of failure is that the pump does not produce water. The possible causes are that the inlet and outlet valves are not open, the inlet and outlet pipes are blocked, and the impeller flow passage is blocked. The motor is running in the wrong direction, the motor phase loss is very slow; the suction pipe is leaking; the pump is not. Filled with liquid, there is air in the pump chamber; the inlet water supply is insufficient, the suction stroke is too high, the bottom valve leaks; the pipeline resistance is too large, the pump selection is improper, the corresponding elimination method is to check, remove the obstruction; adjust the motor direction, tighten Motor wiring; tighten the sealing surfaces to eliminate air; open the upper cover of the pump or open the exhaust valve to exhaust the air; stop the inspection and adjustment; reduce the curve of the pipeline, re-select the pump, of course, the pump of the Shanghai Yi pump will not In case of improper pump selection, according to the actual parameters used by the customer, the technicians of the factory select the most suitable model.

2. In the case of insufficient pump flow, consider the blockage of the flow path of the pipeline and pump impeller, scale deposition, insufficient valve opening; low voltage; impeller wear, the corresponding elimination method is to remove the obstruction and re-adjust the valve opening; Regulated; replace the impeller.

3. There are three major reasons for the excessive power during the use of YG vertical pipeline oil pump, respectively: over the rated flow rate; the suction stroke is too high; the pump bearing wears, the corresponding elimination method: adjust the flow, close the small outlet valve; Suction; replace the bearing.

4. There is noise and vibration in the pump. Consider: the pipeline support is unstable; the liquid is mixed with gas; the cavitation is generated; the bearing is damaged, and the corresponding elimination method: stabilize the pipeline; increase the suction pressure, exhaust; reduce the vacuum; Replace the bearing.

5. Motor heating phenomenon occurs, the cause of the failure is: excessive flow, overload operation; rubbing; motor bearing damage; insufficient voltage, the corresponding elimination method is: close the small outlet valve; check and eliminate; replace the bearing;
