The temperature of the sand pump may be relatively high during the summer. But what is the reason for the high temperature of the sand pump? We can study it carefully.
The sand pump motor is overloaded for a long time, the temperature is often high, and the winding insulation is gradually aging and fails to burn out.
Single-phase operation or long-term voltage is too low, the current increases, and the motor is overheated and burned;
During the pumping process, the water level was excessively lowered, causing the motor of the submersible sewage pump to run longer when exposed to the water surface; due to incomplete well washing or poor management, the motor was buried by sediment;
The motor starts and stops too frequently, causing the motor to overheat;
The cable is damaged or tightly sealed, water penetrates into the cable, and the insulation is burned out, causing a short circuit;
Water and oil in the wet sand pump motor are burnt out due to lack of water and heat dissipation; the impeller or other rotating parts are caught by debris, the motor does not rotate, the overcurrent protection device fails, the stator current suddenly increases, and the winding is burned.
