Brand certification Weihu pump safety deep well submersible pump

Deep well submersible pump is an important product of mineral industry, animal husbandry and agriculture in China. In particular, the use of deep well submersible pumps in agriculture and animal husbandry should pay particular attention to power problems. 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 below 198 volts, the line voltage is lower than 342 volts, submersible pump motor speed down, when less than 70% of the rated speed, start the centrifugal switch will be closed, resulting in long start-up winding power and even burn Windings and capacitors. Conversely, a high voltage causes the motor to overheat and burn out the winding. Therefore, the 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.
    Leakage protection device, also known as protectors, its role from the "security device" the three words can be understood. Wei Shanghai pump brand submersible pump has a number of patents, leakage protection is the days of submersible pump submersible pump R & D and production of one of the important projects. Combined with years of market feedback from users under the premise of large data, Wei-hu pump is deep digging the user pain points, increased R & D funds, through continuous experiments to determine the safety of the product. Because the deep well submersible pumps are mostly in the water, easy to leakage caused by power loss and even lead to electric shock accident, equipped with leakage protection deep well submersible pump, as long as the submersible pump leakage value exceeds leakage protection action current value (generally not more than 30 mA), leakage protection device will cut off the power of the submersible pump to avoid leakage of waste of electricity to ensure safety. It is also on this basis, Wei Hu pump produced by the deep well before each submersible pump factory will automatically control the test stand insulation resistance data monitoring to increase the safety of the pump and the use of more. "Never leave troubles" has also been the heart of Shanghai Wei people to product quality strictly to control the best interpretation.
