Installation and application of fluoroplastics self sucking pump and matters needing attention
1. first check whether the bolts are loose, the power line and plug are intact, the electrical insulation resistance of the motor should be more than 2 Mega.
2. in order to prevent electric shock, it is necessary to install the corresponding security measures, such as the leakage circuit breaker or the electric shock protection device, and to carry out the reliable grounding.
3. pump working voltage range shall be 5% rated voltage -12%, otherwise it will make the service life of the motor cut or burn. If the electric pump is used far away from the power supply, the power supply line should be properly thickened, otherwise it will make it possible.
It is impossible to run with a drop of voltage.
4. turn on the power switch, make the pump empty about 2 minutes, check to start, operation is normal, turn right or not.
5. fixed pump body, steel pipe or a rubber tube (not too soft, so as not to suck, flat) is connected with a water inlet and valve, valve must be placed perpendicular to the horizontal plane, from the bottom of 30Cm or more, so as not to suck on sediment.
6., before the first use of the Qingshui centrifugal pump and the automatic suction water pump, the storage tank should be filled with water. After several dozens of electric energization, it can't automatically discharge water, and it will not need to irrigate after use.
7. from the drain water pump and automatic self suction water pump before use, to the water storage tank filled with water, the water can not automatically energized after tens of seconds, after use without irrigation.
8. when in use, the motor should keep dry, pay attention to the water level decline, not exposed outside the valve. When the temperature is below 4 C. Should do the antifreezing work, to avoid the cracking of pump body.
9., if there is no need for a period of time, we should drain the accumulated water in the net pump.
