Vortex pump is used to suck water and physical and chemical properties similar to the water used in liquid, the use of liquid temperature not exceeding 80 ℃, commonly used in boiler feed water, in shipbuilding, textile, chemical, metallurgy, machinery manufacturing, aquaculture, fixed Fire regulator: heat exchange units, remote irrigation and other agricultural departments have a wide range of applications. Vortex pump (also known as vortex pump) mainly by the impeller, pump and pump cover, belonging to the vane pump. The impeller is a disk, and the blades on the circumference are radially arranged uniformly; the annular flow passage is formed between the pump body and the impeller, the suction inlet and the discharge outlet are both located at the outer circumference of the impeller; This isolates the inlet and outlet. Vortex pump is used to suck water and physical and chemical properties similar to the water used in liquid, the use of liquid temperature not exceeding 80 ℃, commonly used in boiler feed water, in shipbuilding, textile, chemical, metallurgy, machinery manufacturing, aquaculture, fixed Fire regulator: heat exchange units, remote irrigation and other agricultural departments have a wide range of applications. Common problems and solutions of vortex pump: Causes of the malfunction Solution No water after pump start 1. There is no liquid in the pump 2. Suction pipe leakage 3. Impeller and pipe plugging 4. Pump is not steering 5. Inhalation height exceeds the specified requirements (4-5m) 1. Inject fluid into the pump tank. To eliminate air leaks 3. Check and clean the line 4. Check and correct the motor wiring 5. Reduce the pump geometry installation height or reduce the length of the suction pipe power is too large 1. Indenter beyond the scope of use 2. Pump, pump cover and impeller gap is too small 1. Lower the pump head 2. Adjust clearance to the specified range too much leakage seal 1. Mechanical seal static ring and moving ring skew occurs 2. Rubber ring aging 3. Water contains solid impurities 4. Spring loose in mechanical seal 1. Repair or replace to meet the requirements 2. Replace the rubber seal 3. Install a qualified filter 4. Replacement spring displacement reduced by 1. Speed ​​reduced by 2. Impeller or pipeline blockage 3. Pipeline resistance greater than the specified value of 4. Impeller and pump body, the gap between the pump cover is too large 1. Increase speed to rated value 2. Check and clean up debris, rubbish 3. Check the pipe installation, try to reduce the elbow or valve 4. Adjust the gap
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.
