1. Well submersible pumps can generally be used for several years
The design life of deep well pumps can be more than ten years, but the actual service life is generally five to seven years. Depending on the frequency of use, it is recommended to replace the impeller of the pipeline pump every five years. If you hear a very strong friction sound in the motor, you can replace the bearing, disassemble the pump, take out the bearing and see the above model to buy.
The deep well pump is a high-pressure pump with low flow rate. Its life span is four to five years. The impact of cavitation on the pump components is greater. Replacement, the life of the hard plastic beater is three months to five months, the connecting rod shaft is one year, and the motor is five years.
Second, how long can the deep well pump work continuously
If the water level is sufficient, it can work continuously for half a year, and if the water quality is good, it can work continuously for 2 years or more.
Precautions for the maintenance of the deep well pump: replace the lubricating oil, open the oil hole screws in the sealing chamber and the motor respectively, release all the lubricating oil in the sealing chamber and the motor, and replace the new oil to ensure that the lubrication system is normal Work; check wearing parts: the impeller, retaining ring, bushing, bearing seat, etc. of the submersible pump are wearing parts. First, remove the water pump part and check whether the wearing parts are in good condition. It is strictly forbidden to use damaged and unqualified spare parts; disassemble the pump casing to prevent rust. Before use in spring, the upper pump casing should be disassembled, and the impeller should be turned on and then started to prevent the parts from rusting and not starting normally and burning the motor. This maintenance is especially important for water-filled motors.
