The non sealed self priming pump is a new pump equipment produced in recent years. Combined with the characteristics of the previous self-priming pump and the advanced technology innovation, it has the characteristics of good sealing performance, high self suction performance and convenient operation and maintenance. What aspects should be paid attention to the installation and use of an unsealed self - priming pump?
1 check whether the bolt is loose, the power line and plug are intact, electrical insulation resistance should be more than 2 Mega.
2 in order to prevent the occurrence of electric shock accidents, electric leakage circuit breakers or electric shock protectors and corresponding safety measures must be installed, and the ground should be reliably grounded.
The working voltage range of the 3 pump should be in the +5%, -12% of the rated voltage, otherwise the motor will burn and reduce the service life.
4 turn on the power switch, make the pump empty for 2 minutes, check to start, operation is normal, turn right or not.
5 fixed pump, stainless steel pipe, and is connected with the water inlet valve, valve must be placed perpendicular to the horizontal plane, from 30 cm above the bottom sediment, so as not to smoke.
6 the self suction pump before the first use and 6 centrifugal pump, the water tank full of water, water can not automatically electricity for dozens of seconds, no irrigation after use.
7 before the first use of the pump and automatic self-priming pump, the storage tank is filled with water. The water can not be automatically electrified for dozens of seconds, and no irrigation is needed after use.
8 in use, the motor should keep dry, pay attention to the drop of the water level, and do not expose at the end of the valve. When the temperature is below 4, the anti freezing should be done well to avoid the crack of the pump body.
9 If a period of time do not need, should clean the pump inside the water, clean the main ingredients, coated with antirust oil, put in the ventilation and drying place.
