High lift submersible pump installation and use and precautions
1. First check if the bolts are loose, the power cord and plug are intact, and the motor insulation resistance should be greater than 2 megohms.
2. In order to prevent electric shock, it is necessary to install corresponding safety measures such as leakage circuit breaker or electric shock protector, and reliable grounding is required.
3. The operating voltage range of the pump must be between +5% and -12% of the rated voltage, otherwise the motor life will be shortened or burned out. If the electric pump is far away from the power supply, the power transmission line should be properly thickened, otherwise the voltage will drop and it will not work.
4. Close the power switch and let the pump idle for about 2 minutes to check whether it is started, whether the operation is normal, and whether the steering is correct.
5. Fix the pump body, use steel pipe or rubber tube (not too soft, so as not to suck flat), connect the water inlet and bottom valve. The bottom valve should be placed perpendicular to the water level, 30Cm above the bottom of the water, so as not to absorb the sediment.
6. Clear water centrifugal pump use and automatic suction pump Before the first use, the water storage tank should be filled with water. After powering for several tens of seconds, it can not automatically discharge water, and it will not need to be filled after use.
7. Before the first use of the self-cleaning water pump and the automatic self-priming water pump tube, the water storage tank should be filled with water. After being powered for several tens of seconds, the water can not be automatically discharged, and no watering is needed after use.
8. When using, the motor should be kept dry. Pay attention to the water level drop and the bottom valve should not be out of the water. When the temperature is lower than 4○C. Antifreeze work should be done to avoid cracking the pump body.
9. If it is not used for a period of time, drain the water in the pump (high-lift submersible pump and automatic pump to dump the water in the storage tank), scrub the main parts, apply anti-rust oil, and put it in a dry and ventilated place.
