Diving fountain pump is mainly used for fountain water supply, aquaculture and other places. Widely used in low-lift cities, farmland irrigation and drainage, irrigation, industrial and civilian supply and drainage systems, hills, mountain water, and low-lying land to exclude water.
Fountain pump use precautions:
1, let the fountain pump long-term overload
In order to avoid the fountain pump long-term overload, do not draw 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.
2, fountain pump motor rotation direction to be correct
Should find out the direction of rotation of the motor, there are many types of fountain pump 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.
3, cable installation and fountain pump insulation resistance requirements
Install the fountain pump, the cable to overhead, the power cord should not be too long. Fountain pump water, or put forward not to force the cable to avoid breaking the power cord. Fountain pump work not sink into the mud, otherwise it will lead to poor heat dissipation and motor winding motor. Installation, the motor insulation resistance should not be less than 0.5 megohm.
4, fountain pump Qinqin to see the problems found in time to repair
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 in time to avoid water infiltration fountain pump.
5, the installation of leakage protection
Leakage protection device, also known as protectors, its role from the "security device" the three words can be understood. Because the fountain pump underwater work, easy to leakage caused by power loss and even lead to electric shock accident. If equipped with leakage protection device, as long as the fountain pump leakage current value exceeds the leakage protection device (generally not more than 30 mA), leakage protection device will cut off the fountain pump power to avoid leakage of waste of electricity to ensure safety.
6, the power supply voltage abnormal MO start
Rural areas 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 pump motor speed down, when less than 70% of the rated speed, start the centrifugal switch will be closed, resulting in a long start winding power and even burn Windings and capacitors. Conversely, a high voltage causes the motor to overheat and burn out the winding. Therefore, the fountain pump in operation, the operator must always observe the power supply voltage, if less than 10% of the rated voltage, higher than 10% of rated voltage above, the motor should stop running, find out the reasons and troubleshooting.
7, fountain pump to avoid frequent switching
Do not frequent switch fountain pump, this is because the pump will stop when the return flow, if the immediate start, the motor load will start, resulting in starting current is too large and burn out the winding. Due to the large current at start-up, frequent start-ups also burn out the fountain pump motor windings.
