Tool factory 8. Forging factory in automobile manufacturing In the production process, the four processes of stamping, welding, painting and final assembly require a large amount of compressed air. Each factory has an air compressor station and a compressed air pipeline throughout the plant to form a large supply of gas. System. After investigations of some domestic automobile manufacturers, it was found that the pipe network of most factories was arranged in a dendritic shape, and there were serious leakage of compressed air. The leakage was on average about 20%, and the seriousness was 35%. The reason for this situation is mainly because the number of valves and joints of each gas equipment is not strict, some equipment is overpressured, and the automatic unloading is frequently exhausted. Especially when part of the workshop uses gas, the pipe network system cannot be targeted. Sexually supplying gas, causing air compressors to do virtual work.
According to the results of several tests conducted by our factory, when only the stamping plant is supplied with gas, the gas supply is about 1200m3/h, and the leakage of the whole pipe network is about 400m3/h, which wastes a lot of electricity, cooling water and lubrication. Oil, which accelerates mechanical wear.
Implementation of the improvement plan In response to the above situation, our factory implemented an improvement on the compressed air pipe network. (1) The original dendritic gas supply side.
Undertake thermal spray anti-corrosion construction, spray zinc and aluminum, ceramics, plastics, stainless steel, copper, lead, molybdenum and so on.

AH(R) Series Heavy Duty Slurry Pumps are cantilevered horizontal, centrifugal slurry pumps .They adopt the vertical axial middle open type and double casing structure. They are designed for handling high abrasive, high-density slurries in alumina, copper, electric utilities, phosphate, coal, building products, Iron ore, lead & zinc and other industrial departments etc. The pumps of this type may also be installed in multistage or/and in series.
Product Feature
1.The flow-passing parts is made of wear-resisting metal or rubber liner, has the good wear-resisting, the corrosion resistance and the high reliability.
2. Large diameter impeller and low running speed design, has higher service life and lower running cost.
3. High capacity bearing design, using grease or oil lubrication to adapt to different operating conditions.
4. The clearance between the impeller and the cover plate could be adjusted to ensure the pump to operate at high efficiency point.
5. The shaft seal adopts packing seal, expeller drive seal and mechanical seal, which adapts to different working conditions.
6. The discharge branch can be positioned at intervals of 45 degree by request and oriented to any eight positions to suit installation and application.
