Submersible pump usage precautions

Submersible pump before use is very important choice, should be based on the actual situation of the water source and working hours and pump water and other requirements to select the pump model. First of all, to choose the lift head is greater than the gap between the water inlet and outlet; followed by the pump flow to be able to meet the drainage and irrigation requirements. (A) the use of submersible pump environmental requirements 1, a safe and reliable power supply. 2, the outlet pipe and pool water surface drop less than the head. 3, to choose a relatively clean water. (B) Start 1,11 kilowatts submersible pump to allow direct start. Submersible pumps above 13 kW should be equipped with a buck starter. To protect the safe operation of submersible pumps. 2, in order to avoid submersible pump rotor momentarily channeling and reduce the starting load. Submersible pump should be started when the exit valve trip to 3/4 Department. (Leaving 1/4 air gap in order to deflate) to be started after the water slowly open. To the pump operating point control in place. 3, start after the start of operation. Care should be taken to monitor and observe changes in water level. Submersible pump to ensure that the operating conditions. Submersible pump to be run smoothly until put into formal operation. 4, submersible pump first put into operation 5 hours later. Shut down quickly measure thermal insulation resistance. Its value is not less than 0.5MΩ. Can continue to use. (C) operation 1, the submersible pump should work at the design conditions. The axial force is moderate at this moment. The highest pump efficiency. The most economical and reliable. 2, submersible pump every 8 hours of operation to be fully inspected once. Is there any change in each meter? Whether the circuit node is hot. The sound is normal. Normal working current is greater than the rated value of the motor brand. Note that one of the following conditions should be immediately stopped pump: 1, the pump current suddenly higher than the rated current of the motor. 2, the water is not normal, intermittent water. Increased sediment concentration. 3, the motor insulation resistance is less than 0.5 megohms. 4, the unit has obvious noise aggravating. 5, the grid voltage is not enough. Below 5% of rated voltage. 6, the fuse burned one phase. 7, water pipeline damage. (D) stop pump submersible pump down before. To prevent the backflow of water. Turn off the valve while the power is off. Restart more than 20 minutes later. (E) Submersible Pump Notes 1, the power must be grounded and reliable, install leakage protector. 2, the outlet pipe as much as possible not to bend, promptly find and repair the pipe rupture, to reduce power loss. 3, more debris on the water pumping to add Filters . 4, before starting the positive and negative power supply, so as not to reverse the pump, no water. 5, the use of found abnormal circumstances, the timely cut off the power to find out the situation to resume before they can continue to work.
