Will the temperature rise rapidly when a magnetic pump operates in reverse direction, and can the material carry away heat?
Thread Content
The design of magnetic pump differs from that of centrifugal pumps; during normal operation, the heat generated by mechanical friction can be carried away by the material itself. Can the material carry away heat when the pump runs in reverse? When the pump is stopped, the material is allowed to flow back (using other power equipment); at this point the impeller of the pump rotates in the opposite direction. Is heat removed during this process? If the material flows backward at 20 degrees at the pump outlet, can it remain below 30 degrees when it comes out of the inlet?
During reversal, it operates as a hydraulic recovery turbine; the pressure at the pump outlet remains higher than that at the inlet. The axial force and flow rate are essentially similar to those when the pump is operating in normal mode. However, it is crucial to avoid such operation, as it can cause harm!
