General factory sewage pump industry standard warranty for one year, but even if it is produced in the same factory the same types of pumps, because of the use of environment, regulate the operation, transportation of materials of different, the longevity gap is huge. In the exclusion of selection errors, transport, misuse and extremely bad conditions and other special reasons for the use of the normal circumstances, in addition to vulnerable parts, the sewage pump to use two or three years is not a problem. More than five to eight years may also be used.
This is more obvious in terms of the standard operation and the maintenance of regular maintenance. In order to better ensure the submersible pump can stabilize and, long-term use, Hubei Quan pump to explain to you extend sewage pump using seven skills of life
1. The installation of sewage pump, to the overhead cable, power line not too long. Discharge pump water or put forward not to make the cable force, so as not to cause power line fault. Sewage pump work do not sink into the mud, otherwise it will lead to poor motor cooling motor windings burned. When installation, the insulation resistance of the motor should not be lower than that of the.
2. Do not frequently switch sewage pump, this is because the pump switch to stop the return will produce, if an immediate start, will start the motor load, leading to the starting current is too large to burn winding. As the start when the current large, frequent starts will burn sewage pump motor winding.
3. Should make clear the direction of rotation of the motor, and now there are many types of sewage pump is turning and reversing all available water, but the reverse when the water is small, the current large, and its reversal time will be damaged by the motor winding.
4. Due to the low voltage power supply line is relatively long, the end of the line is too low voltage. When the phase voltage below 198 volts, line voltage lower than 342 volts, submersible pump motor speed to drop, when up to 70% less than the rated speed, start centrifugal switch closed, resulting in start winding head of time electricity and heat and even burn winding and capacitor. On the contrary, caused by high voltage motor overheating and burn winding. Therefore, the submersible pump in the operation, the operator must observe the power supply voltage, if less than 10% of the rated voltage, higher than the rated voltage of 10% or more, should be to stop the operation of the motor, to find out the reasons and troubleshooting.
5. Leakage protection is also called the life of the device, it's role from the "life" of the three words can be understood. Because submersible pump works under water, easy to leakage caused by power loss or even lead to electric shock accident. If equipped with leakage protector, as long as the submersible pump leakage values over the action current of leakage protector value (generally not more than 30 MA), earth leakage protection device will cut off the submersible pump power, to ensure the safety while avoiding leakage and waste of energy.
6. Usually to often check the motor, such as the discovery of cracks, rubber seal ring damage or failure, etc., should be replaced or repaired in a timely manner to avoid infiltration of water into the submersible pump. The use of submersible pump and focus on some of the daily protection can better extend the life of the submersible pump.
7. To avoid submersible pump long-term overload of work, do not smoke large sediment water and always observe the current whether in the nameplate on the provisions of the numerical value, if too much current is found should be down to check. In addition, the electric pump running time should not be too long, so as to avoid overheating and burning motor.
