The motor is smoking; could everyone help analyze the reason?
Thread Content
The mechanic had just finished repairing the pump and was about to test it; when it was started, water did not flow from the outlet. It was observed that there was still some leakage from the seal, so it was assumed that the seal’s water supply pipe was the cause. The pipe was removed, and after less than 3 minutes of operation, the seal continued to leak, prompting the decision to repair it again. However, after it stopped, I noticed smoke coming from the motor, along with a strong burnt smell What causes this? ?
A circulation pump containing circulating fluid, with the inlet open and the outlet closed; pressure is generated at the outlet when the pump is activated
Has the pump been running with the outlet closed for too long?
If that’s the case, with the export closed for an extended period, what impact will that have? In my personal opinion, is more mechanical energy converted into internal energy?
Is it easy to operate a hand-cranked pump? When a motor starts smoking, it is usually because the motor is overloaded and too hot; in severe cases, the motor gets damaged. :) It is recommended to manually turn the pump before starting it; start the pump only after ensuring that it turns smoothly.
It also depends on the properties of the liquid circulating within the pump; if special factors such as the tendency of the medium to vaporize cause significant damage to the pump, it will naturally also cause damage to the motor. Generally, the shutdown time of a running pump should not exceed 60 minutes.
Thank you, friend; the pump was tested for definitely no more than 5 minutes
Cavitation? The vibration sound in the pipeline is normal
I’m sorry, there was a typing error; it’s 60 seconds, I mistyped it as minutes. 5 minutes is already a long time.
Are the pipe temperature, pump casing temperature, and pump outlet pressure gauge normal?
