Why do the liquid of centrifugal pump back-flow?

Wednesday, 20 September 2017 by admin
The flow of liquid is maintained by the energy gradient. When the flow is reduced to near zero, the impeller may increase the peripheral velocity around the inlet due to the action of the inertial force of the liquid, so that the energy near the wall increases, which keeps the liquid flowing The energy slope

Submersible pump sediment concentration and motor winding temperature

Thursday, 14 September 2017 by admin
If there is no safety valve, blindly raise the temperature of the magnet wire, such as 180 ℃, 200 ℃, or even 240 ℃, the probability of explosion will be higher. This is because the winding temperature is getting higher and higher, it will produce saturated steam to provide higher temperature, more heat, will lead
