Check the wearing parts: the impeller, buckle, shaft sleeve, bearing seat, etc. of the submersible pump are wearing parts. First of all, the water pump should be partially removed to check whether the wearing parts are in good condition. It is forbidden to use damaged and unqualified spare parts.

For the submersible pump should do some necessary checks before starting: whether the rotation of the pump shaft is normal, whether there is a stuck phenomenon; whether the position of the impeller is normal; whether the cable and cable plug is broken, scratched and broken. During operation, pay attention to the change of voltage, which is generally controlled within ± 5% of the rated voltage. In addition, the position of the pump in the water is very important. It should be selected as far as possible in a place with abundant water, no silt and good water quality. It should be suspended vertically in the water (note: never use cable to suspend it). It is not allowed to be placed horizontally, so as not to fall into mud or be blocked by suspended substances, resulting in sharp reduction of water output or even failure to pump water.

Hello! Due to the cold weather in winter and freezing weather in the near future, submersible pumps are very easy to freeze and crack. Please do a good job in antifreeze! Avoid causing unnecessary losses and troubles to you.

GB/T 2818 "well with submersible asynchronous motor" product standard for well with submersible motor conditions are as follows.

Well submersible pump is composed of well submersible three-phase or single-phase (asynchronous) motor and well submersible pump, which is submersible pump used to pump groundwater or water to high or long distance. The overall structure of the well submersible electric pump is very different from that of the ordinary land asynchronous motor.
