Self - priming magnetic pump common fault and troubleshooting methods

With the continuous improvement of pump technology, self-priming magnetic pump is used more and more frequently, greatly improving the work efficiency, reduce operating costs, but in the process of using self-priming magnetic pump inevitable Will encounter various problems, continue to create trouble for us, and now share with you some of the self-priming magnetic pump common fault and treatment. Fault 1: self-priming magnetic pump does not water a, reverse pump troubleshooting method: to change the motor wiring b, water pipeline leak check method: to prevent leakage c, pump cavity too little Check the investigation method: increase the storage capacity d , The voltage is too high, start the coupling slippery investigation method: adjust the voltage e, suction stroke is too high Troubleshooting method: to reduce the sand installation location f, the valve does not open Troubleshooting method: correct or change the valve Fault 2: insufficient magnetic flux pump a, inhalation Pipe diameter is too small or fouling Check method: Exchange the inlet pipe b, impeller flow path obstruction Check method: Clean the impeller c, high lift Check method: Open the valve d, speed is not enough Troubleshooting method: to restore the rated speed Fault three: A low magnetic head pump a, flow is too large Inspection method: off the small water valve b, the speed is too low Troubleshooting method: to restore the rated speed Fault four: too much noise a, serious wear and tear Axis inspection method: replacement pump shaft b, sleeve Severe wear and tear troubleshooting method: Replace the sleeve c, drive magnet cup and isolation sleeve contact troubleshooting method: Remove the pump head reassembly d , Seal ring and impeller grinding Inspection method: replacement thrust ring, seal ring The above is some self-priming magnetic pump in daily life, a summary of common faults, Xiao Bian sorted them out for your reference study, I hope we can send in the future Use, and continue to enrich the use of self-priming magnetic pump tips.

The production process of copper in China is dominated by copper concentrates and pyrotechnic smelting of blister copper. The status quo is that the processing capacity is greater than the smelting capacity, smelting capacity has greatly exceeded the support capacity of copper concentrate, copper concentrate resources and scrap copper imports are required. Statistics show that in the 21st century, the output of domestic copper concentrate has not been significantly increased, maintaining an annual output of 600,000 tons (copper content, the same below), by the end of 2007 will form nearly 3.7 million tons of smelting capacity, far exceeding By then China's copper concentrate resources and the protection of the capacity of the international market may provide the amount of copper concentrate. The production capacity of copper mines in China can only meet 40% of the smelting capacity.
