Seven Precautions for Stainless Steel Fountain Pumps

1, let the stainless steel fountain pump long-term overload

In order to avoid long-term overload of stainless steel fountain pump work, do not smoke a large amount of sand and observe the current value whether the value specified in the nameplate, 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, the direction of rotation of the motor to be correct

Should be clear the direction of motor rotation, there are many types of stainless steel fountain pump forward and reverse are available when the water, but the reverse water volume is small, the current is large, the reversal of a long time will damage the motor windings.

3, cable installation and stainless steel fountain pump insulation resistance requirements

Installation of stainless steel fountain pump, the cable to overhead, the power cord should not be too long. Stainless steel fountain pump water or put forward do not make the cable force, so as not to cause power line breakage. Stainless steel 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, Qinchu 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 repair, to avoid water infiltration of stainless steel fountain pump.

5, the installation of leakage protection

Leakage protection, also known as security device, its role from the "security device" the three words can be understood. Because the stainless steel fountain pump in the water work, easy to leakage caused by power loss or even lead to electric shock accident. If equipped with leakage protection, as long as the leakage of stainless steel fountain pump leakage current value exceeds the leakage protection device (generally not more than 30 mA), leakage protection will cut off the power supply of stainless steel fountain pump to avoid leakage of waste electrical energy 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 below 198 volts, line voltage below 342 volts, stainless steel fountain pump motor speed down, when less than 70% of rated speed, start the centrifugal switch will be closed, resulting in a long start-up 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 stainless steel fountain pump in the operation, the operator must always observe the power supply voltage value, if less than 10% of the rated voltage below the rated voltage above 10%, should stop the motor to find out the cause and troubleshooting.

7, to avoid frequent switching

Do not frequently switch stainless steel 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. As the start current is very large, frequent start will burn the stainless steel fountain pump motor windings
