Precautions when using various self-priming centrifugal oil pumps 1. When using, the motor should be kept dry. Pay attention to the oil level drop and the bottom valve should not be exposed to the oil surface. When the temperature is below 4 °C. Antifreeze work should be done to avoid cracking the pump body.

the led ceiling fan category is included ABS Ceiling Fan light ,like this 5 blades ceiling fan light . it is fan and light 2 in 1 together.
the led ceiling fan is included blades , lamp shape , canopy , motor and down rod .about the blades material , it also has abs ,plywood,iron,
wood.
this is the retractable led ceiling fan .the blades will stretch out and put inside automatically .
the wood led ceiling fan is made for the solid walnut wood blades , pass the organic certification .
about the led ceiling fan motor , it is whole inverter cooper motor , it is save energy and silent when working . it is high quality and durable , and
not easy to broken .
2. If it is not used for a period of time, drain the oil in the pump (self-priming centrifugal oil pump and automatic pump to dump the oil in the storage tank), scrub the main parts clean, and put the anti-rust oil on the Botaibang. Alternate.
3. Self-priming centrifugal oil pump is to prevent electric shock accidents. It must be equipped with corresponding safety measures such as leakage circuit breaker or electric shock safety device, and must be reliably grounded. 4. Fix the pump body, self-priming centrifugal oil pump steel pipe or rubber hose (Do not be too soft, so as not to suck flat), connect the inlet port and the bottom valve. The bottom valve must be placed perpendicular to the oil level, 30Cm above the oil base, so as not to absorb the sediment.
5. Clean oil centrifugal pump use and automatic suction pump Before the first use of the oil pump, the oil storage tank should be filled with oil. After powering for several tens of seconds, the oil can not be automatically discharged. After use, there is no need to fill the oil.
6. Before the self-priming oil pump and the automatic self-priming oil pump tube are used for the first time, the oil storage tank should be filled with oil. After powering for several tens of seconds, the oil cannot be automatically discharged, and it is not necessary to fill the oil after use.
7. 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 thickened properly, otherwise the voltage will drop and it will not work.
8. Close the power switch and let the pump idle for about 2 minutes. Check the start, whether the operation is normal, and whether the steering is correct.
9. 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.
