Stainless steel deep well pump conditions of use and precautions
QJ-type deep diving submersible pump is a direct-acting motor and pump dive into the water work of lifting equipment, submersible pumps, submersible motors, pipes, cables and start-up protection devices and other components. Now to introduce the use of stainless steel deep well pump conditions and precautions in use. Stainless steel deep well pump First, the stainless steel 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 (to be installed in place and can be successfully promoted, subject to more severe deflection, borehole should be slightly larger or use a smaller diameter of the pump). 6, the well must have sufficient inflow (ie greater than the rated flow). Second, the use of stainless steel deep well pump Notes 1, before going to the well should be checked, the Department of screws loose, cable break, the motor is leaking, motor shaft, pump shaft rotation is flexible. 2, check the motor resistance before entering the well should be 150 megohms or more. 3, motor water should carefully prevent fake. 4, the protection switch and start equipment should be provided with the standard. 5, the motor running 2500 hours should be an overhaul, 1500 hours should be minor overhaul. 6, diving deep well pump downtime should be put out of the motor memory water. 7, prohibit frequent open, stop. 8, the ground test motor steering in an instant less than one second.
