What Are The Reasons Why The Water Pump Cannot Run When Starting, And What Are The Countermeasures?

Aug 24, 2024

① Motor voltage too low:
a) Low power supply voltage;
b) The cross-sectional area of the power supply line is small;
c) The power supply line is too long;
② Power phase loss:
a) Poor contact of power switch;
b) The fuse is blown;
c) Loose power supply line;
d) Power line phase failure;
③ Bearing stuck;
④ Impeller stuck;
⑤ Motor burnt out;
The corresponding response measures are as follows:
① A) Adjust the voltage to the rated requirement range;
b) Replace the power supply line with a larger cross-sectional area;
c) Shorten the length of the power supply line;
② A) Repair the switch contacts or replace the switch;
b) Replace the fuse;
c) Check and tighten the power supply line connectors;
d) Repair or replace power lines;
③ Replace the bearing (send it to the repair point for maintenance);
④ Disassemble the water pump to remove debris;
⑤ Replace the motor (send it to a repair center for maintenance).
