Two-phase submersible pumps are popular with farmers for their ease of use and ease of handling. However, due to improper use and poor maintenance, destruction often occurs. Therefore, we should pay attention to the use and maintenance methods so that they can achieve their normal performance and reduce unnecessary economic losses. First, connect the power supply correctly. The submersible pump's power supply line must be installed in accordance with the rules of electricity usage, and must not be connected privately. Field operations cannot be hooked up. Not only is hooking and connecting to electricity dangerous, it is prone to safety accidents, and it is a kind of electricity stealing behavior that can be investigated and punished by the power supply department. If the submersible pump is operated with long-distance cables, a double-knife switch should be installed near the submersible pump to cut off the power quickly in the event of an accident. To install the electric shock protector, it should always be sensitive and reliable, so that in the event of an accident it will automatically cut off the power, so that the electric shock from danger and ensure safety. Before working, check whether the voltage of the power supply is 220 volts. If the voltage is too high or too low, the motor may be burned. Second, check before use. First check the looseness of each part of the screw, if any loosening immediately tighten; then check the cable and plug for damage, breakage, cross-line, if necessary, remove; then check the power supply voltage is 220 volts, too high or too low All may burn the motor. Third, according to the provisions of the use of the lift. Different types of submersible pumps are used according to their prescribed lift, and they must not exceed the lift to make the load too large. The supporting water pipes should also meet the requirements of the regulations. Fourth, the submersible pump's diving position should be appropriate. Submersible pumps should be lifted vertically when diving into the water. They should not be lying on the ground, nor should they be trapped in the mud. The diving depth of the submersible pump is generally 0.5 to 3 meters. After the water level drops during pumping, care must be taken not to allow the submersible pump to run out of the water. Fifth, the submersible pump must be lifted with ear-climbing. When you put in the water or raise the water surface, you must use a rope to pull the ear-lifter. Do not use the cable to lift the pump rope to avoid line failure or electric shock. 6. When the submersible pump is not in use, do not soak it in water for a long time. The sediment should be wiped clean and coated with anti-rust oil. Hang it in a dry and ventilated place in the room to prevent the motor stator winding from getting wet.
