Pump failure - reversal

Before the pump for you to introduce some knowledge about the pump, including its own characteristics and common causes of problems and solutions, I believe we have a deeper understanding of the pump, the pump common There are many problems, including noise, high operating energy consumption, the following is to introduce another common problem of pumps - reversal. Pump reversal fault first of all for everyone to explain the cause of the pump reversal phenomenon. When there are several pumps running side by side or a pump running alone, if the pump suddenly stops rotating, the pump outlet check valve lax, pump reversal phenomenon will be very easy to appear in the event of a reversal of failure is not Start, otherwise it will be very easy to damage the shaft and motor, so when this happens, it is necessary to immediately shut down the pump outlet valve, at the same time the backup pump starts, it must be remembered. The following is a description of the pump will bring the harm to the reverse. When the pump reversal phenomenon, the outlet manifold pressure may be a sharp decline in the situation, in addition, may also lead to loosening of the impeller, so that the dynamic friction part of the pump, resulting in damage to the relevant components, affecting the overall pump Running, and even bring security risks. In addition, when the pump reversal problems, its head will be very low, serious time will not hit the water. (Editor: LLX QQ:) Recommended reading: 2017 Exhibition Information 2016 Yiwu Fair
