Common maintenance failures of sewage pumps

Yiou
What should I do when the sewage pump fails? We need to understand the common maintenance failures of sewage pumps. 1. The power supply voltage is too low a. Transformer output voltage is low Solution: adjust the transformer voltage b. The cross-section of the power supply line is too small Solution: use a line with a larger cross-section c. The power supply line is too long. Treatment method: move closer to the transformer 2. The voltage drop of the power cable is too large a. The cable is too long. Treatment method: cut off the excess part b. The cross ... Read More

The reason for the decline in the operating efficiency of the sewage pump

Yiou
What are the reasons for the decline in the operating efficiency of the sewage pump? There are the following: 1. Due to the scouring of the water flow, the inner wall of the sewage pump flow channel and the impeller passing water surface become rough and uneven, the friction coefficient of the flow channel in the sewage pump increases, and the water flow rate in the pump is large, and the head loss increases. Hydraulic efficiency is reduced. 2. Due to the reasons such as adding medicine or water quality before the sewage pump, the pump casing is seriously fouled ... Read More
