Self-priming pump installation considerations

[Self-priming pump self-priming pump installed quality is good or bad, affecting the quality of the pump, or even the life of the pump, then install the pump, you need to pay attention to what? Now Xiaobian to introduce Self-priming pump installation considerations. Controlled self-priming pump installation considerations 1 first check everywhere bolts loose, the power cord and the plug is intact, the motor insulation resistance should be greater than 2 megohm. 2. In order to prevent electric shock accident, it is necessary to install the corresponding safety measures such as earth leakage circuit breaker or electric shock safety device, etc., and to conduct reliable grounding. 3. The operating voltage of the pump should be used in the range of +5% and -12% of the rated voltage, Otherwise it will reduce the motor life or burn out. Electric pump as far away from the power supply, power transmission line should be appropriate bold, otherwise it will use the voltage drop and can not run. 4. Close the power switch, the pump idle for about 2 minutes to see the start, the operation is normal, the steering is correct. 5. Fix the pump body with steel pipe or rubber hose (must not be too soft to avoid suction), connect the inlet and the bottom valve, and the bottom valve must be placed perpendicular to the water level above 30cm from the bottom so as to avoid absorbing the sediment. 6. Clean water centrifugal pump to use and automatically suck the pump for the first time before use, it is necessary to fill the tank water, electricity can not automatically after a few seconds out of water, the future does not require irrigation. 7. Since the pump and automatic self-priming clear water pump tube for the first time before use, it is necessary to fill the water tank filled with water, electricity can not automatically after a few seconds out of water, the future does not require irrigation. 8. Use, the motor should be kept dry, pay attention to the water level down, the bottom valve can not be exposed outside the water. When the temperature is below 4 â—‹ C. Antifreeze should be done, so as not to freeze the pump body. 9. If not for a period of time, should drain the net water pump (self-priming pump and automatic pump down the water storage tank), the main components scrub clean, coated with anti-rust oil, placed in a ventilated and dry place for future use. In summary is the installation of self-priming pump considerations, these are for your reference.
