In the process of using the electric reciprocating pump, sometimes there will be some failures, such as the pump can not be started after the start of the pump, the pump issued a noise and so on. We know that there must be a reason for the emergence of a problem. If we find the source of the problem, we can solve the problem. Below, the main fault analysis of electric reciprocating pump can help everyone to determine the cause of the malfunction, to take appropriate measures. Analysis of the main failure of electric reciprocating pump 1, the pump can not be started after the start of the fluid: ①packing tight or cylinder liner, expansion ring worn too much, bakelite ring shrinkage or stuck; ② suction valve, row valve damage, put Or serious leakage; ③ suction tube leaks; ④ mouth exposed liquid level; ⑤ suction tube blockage (filter dirty block or stop valve is not open); ⑥ pumping too much, or pipeline resistance is too large; Temperature is too low, the viscosity is too high; ⑧ inhalation of liquid temperature is too high; ⑨ bypass somewhere discharge (safety valve leakage or spring too loose); ⑩ exhaust line obstruction and safety valve open. 2, the pump abnormal noise: ①percussion in the pump cylinder, the cylinder may fall into foreign matter or piston nut loose; ② friction within the cylinder, the filler may be too tight or piston ring fracture; ③ valve box Of the percussion, the spring may be broken or lack of elasticity, so that the valve lift is too large; ④ transmission components gap is too large; ⑤ percussion in the pump cylinder may also be "liquid attack", then inevitably accompanied by suction vacuum Yamaha and pressure gauge pointer significant swing and other characteristics, see the first fault above ⑤-⑧ items. The main fault analysis of the electric reciprocating pump is introduced in two aspects, which explains in detail the possible causes of the abnormal noise that can not be supplied to the pump and the pump after the pump is started. Users in the use of the process, if you encounter the above problems, you can refer to the above analysis to determine, and then take appropriate measures to solve the problem.
