Fountain submersible pump service life

Fountain submersible pump industry standard warranty period of one year, but even the same manufacturer of the same type of water pump, because the use of the environment, operating standards, the different materials, the life gap is huge. In addition to the selection of fault, transportation, misuse and extremely harsh operating conditions and other special reasons outside the normal circumstances, in addition to wearing parts, fountain submersible pumps to use two or three years is not a big problem. Many may also be used for five to eight years.

From the transport of materials to analyze: If you contain a lot of hard dirt, fountain submersible pump over-current material will speed up wear and tear, but in the transmission of similar lubricating substances, will play a role in extending life, so the industry did not Fountain submersible pump life to a standard material under the test method and basis, but directly through the quality of the package to explain.

From the standard operation and adhere to the regular maintenance aspects, this is even more obvious. In order to better ensure that the fountain submersible pump is stable and efficient long-term use, for all customers given the following meaning:

1, should find out the direction of rotation of the motor, there are many types of fountain submersible pump is forward and reverse when the water can be, but the reversal of small water, the current is large, the reversal of a long time will damage the motor windings.

2, as a result of low-voltage power supply line is relatively long, the end of the line voltage is too low is common. When the phase voltage is less than 198 volts, the line voltage is lower than 342 volts, the fountain submersible pump motor speed down, when less than 70% of the rated speed, start the centrifugal switch will be closed, resulting in long start winding power and heat or even burn Bad windings and capacitors. Conversely, a high voltage causes the motor to overheat and burn out the winding. Therefore, the fountain submersible pump in operation, the operator must always observe the power supply voltage value, if less than 10% of the rated voltage, higher than 10% of rated voltage above, the motor should stop running, find out the cause and troubleshooting.

3, install the fountain submersible pump, the cable to overhead, the power cord not too long. Fountain submersible pump into the water or put forward not to force the cable to avoid breaking the power cord. Fountain submersible pump work do not sink into the mud, otherwise it will lead to poor heat dissipation and electrical motor winding. Installation, the motor insulation resistance should not be less than 0.5 megohm.

4, leakage protection device, also known as security device, its role from the "security device" the three words can be understood. Because the fountain submersible pump in the water, easy to leakage caused by power loss and even lead to electric shock accident. If equipped with leakage protection device, as long as the leakage of fountain submersible pump leakage current value exceeds the leakage protection device (generally not more than 30 mA), leakage protection device will cut off the fountain submersible pump power to ensure safety, while avoiding leakage, waste Electricity.

5, do not frequently switch fountain submersible pump, this is because the pump stall will produce a return flow, if immediately start, will make the motor load start, resulting in starting current is too large and burn out the winding. As the start current is very large, frequent start will burn the fountain submersible pump motor windings.

6, in order to avoid the fountain submersible pump long-term overload, do not smoke a large amount of sediment water and observe whether the current value specified in the nameplate value, if the current is too large, should stop inspection. In addition, the dehydration pump running time should not be too long, so as not to make the motor overheating and burned.

7, usually should always check the motor, if found under the cover of a crack, rubber seal ring damage or failure, should be replaced or repaired, to avoid water infiltration fountain submersible pump. The use of fountain submersible pump protection and pay attention to some of the daily protection can better extend the fountain submersible pump life.
