Several precautions for the installation of stainless steel sewage pump

1. Check whether the bolts are loose or not. The stainless steel sewage pump and plug of the power cord are intact. The insulation resistance of the motor should be greater than 2 megohms.

2. In order to prevent electric shock, it is necessary to install corresponding safety measures such as electric leakage circuit breaker or electric shock protection device, and reliable grounding is required.

3. The working range of the pump working voltage must be between +5% and -12% of the rated voltage of the cooling pump, otherwise the service life of the motor 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. Check whether the vertical pipeline centrifugal pump starts, 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 the bottom valve, the bottom valve must be placed perpendicular to the horizontal plane, 30Cm above the bottom of the water, so as not to absorb the sediment.

6. The use of clear water centrifugal pump 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. 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 energized for several tens of seconds, the water cannot 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 condition, and the bottom valve should not be exposed outside the water surface. When the temperature is below 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 (self-priming pump and automatic pump to drain the water in the storage tank), scrub the main parts clean, apply anti-rust oil, and put it in a dry and ventilated place.
