step 3, the controller controls the vacuum water pump to pump air in the pump body to enable the interior of the pump body to be vacuum, under the action of atmospheric pressure, water at a water source flows into the pump body along the connecting pipe through the auxiliary water suction mechanism, the controller receives liquid level information transmitted by the depth sensor to carry out comparison processing to judge whether the pump body is full of water or not, and the variable frequency motor is controlled to work when the pump body is full of water;
and 4, detecting the current value of the variable-frequency motor by the current sensor and transmitting the detected current information to the controller, receiving the current information by the controller for comparison and calculation, and controlling the vacuum pump to pump water in the pump body to cool the variable-frequency motor by the controller when the current value of the variable-frequency motor reaches a preset maximum value until the current of the variable-frequency motor is stabilized at the preset current value.
