1, The reason why the impeller of the water pump cannot be removed
There are generally several reasons why the impeller of a water pump cannot be removed: first, the impeller is excessively corroded and gets stuck on the shaft; second, the impeller is stuck on the shaft, and the structure between the impeller and the shaft is not tight, making it difficult to remove; third, long-term use of water contains too many impurities and mud, which can cause the water pump to get stuck.
2, Dismantling method
1. Use ice water
Soaking the water pump impeller in ice water causes a decrease in the temperature of the water pump impeller and shaft, and the impeller is prone to detachment due to cooling and contraction.
2. Hot water
Soaking the impeller of the water pump in hot water causes it to expand due to heat, increasing the gap between it and the shaft, making it easy to remove the impeller.
3. Add an appropriate amount of acidic water
Soak the acidic water between the impeller and the shaft, and its chemical composition can dissolve the corrosive substances between the impeller and the shaft, making it easy to disassemble.
4. Use an Allen key
Insert the hexagonal key into the water pump impeller and rotate it to unscrew the impeller, easily solving the problem of impeller jamming.
The above methods can effectively solve the problem of the impeller of the water pump not being able to be removed. At the same time, we should pay attention to maintenance and timely cleaning in daily use, and try to avoid the impeller being stuck by mud and other debris.
