QJ diving deep well pump conditions and precautions

QJ-type diving deep well pump is suitable for extraction of groundwater from deep wells, can also be used for water projects such as rivers, reservoirs, drains, etc. It is mainly used for farmland irrigation and water supply for livestock and poultry in plateau and mountainous areas, but also for cities, factories, Railway, mining, construction site for water supply and drainage. Xiaobian hereby summarize the conditions and precautions for QJ-type diving deep well pump. QJ diving deep well pump, QJ diving deep well pump conditions of use 1, the power supply is 50Hz, 380V three-phase AC. 2, the first impeller pump should be diverted to move the water level below 1 m, bottom of the motor from the bottom of not less than 3 meters, but not more than 70 meters into the water depth. 3, the water solids content (by mass) is not more than 0.01%, PH value in water 6.5 ~ 8.5, chloride ion content of not more than 400mg / I. 4, the water temperature is not higher than 20 ℃. 5, the well should be upright (in order to be installed in place and can be successfully promoted subject, if the deflection more powerful, diameter should be slightly larger or choose a smaller diameter of the pump) 6, the well must have sufficient inflow (ie Greater than the rated flow). Second, the use of deep well QJ diving precautions 1, before going to the well should be checked, all the screws are loose, the cable has no break, the motor is leaking, the motor shaft, pump shaft rotation is flexible and unobstructed 2, downhole check motor resistance At 150 megohms or more; 3, the motor water to prevent fake full; 4, the protection switch and starting equipment should be equipped with the provisions of; 5, the motor runs 2500 hours should be an overhaul, 1500 hours should be minor overhaul; Deep well pump downtime should be stored in the motor memory water; 7, prohibit frequent open, stop; 8, the ground test motor steering in less than one second instant.
