Reasonable selection of air compressor equipment for compressed air station

Industrial Technology Compressed Air Station Room Air Compressor Equipment Reasonable Selection Li Guoqing Hunan Changfeng Automobile Manufacturing Co., Ltd. Responsible for the stipulation of the technical requirements of the public tongue production of the public in the stone flow autumn equipment selection 1 Overview Hunan Changfeng Automobile Manufacturing Changsha Co., Ltd. is a car production base with a production capacity of 10,000 vehicles per year. The gas consumption of each production department of the company adopts the principle of centralized production system supply, and the normal supply of gas to the stamping group is completed by the various pipelines of the compression station.

2 Load calculation and design selection 2.1 Compressed air consumption of each department 12.2 Load calculation type B. The average consumption of compressed air in each workshop is 0.15, and the consumption coefficient of gas equipment is taken as 0.15. The outlet pressure of the press is 0.7, the outlet pressure of the air compressor station is 6751 mass flow gamma = 6.77 punching workshop 1 = 3251 pipe diameter 0, 25 mass flow gamma = 2.251 several pipe diameter 0 like 50 mass flow coffee = 4.91 period The flow coffee = 6.21 period is calculated to the pressure of each process point of use is not less than 2.2.1 Compressed air station station room composition Compressed air station composition including the variable distribution room control room machine room circulating pump house. The selection of the air compressor according to the single-type centrifuge or screw machine is beneficial to the automatic control of the equipment and the realization of the microcomputer control of the station.

According to the design capacity of the compressed air station and the gas requirements of each production workshop, the air compressor is selected according to the centrifugal air compressor. The design uses 0, and two 603 sets are specially designed for stamping and painting welding.

In order to ensure the quality of the gas in the workshop, a freeze dryer is installed in the air compressor station to purify the compressor air to remove moisture and solid matter in the compressed air. The freeze dryer has a total of Taiwan, 250 claws 3 such as Taiwan 80 Yang 3 for the dedicated machine.

The design calculation and equipment selection of the station capacity are designed according to the gas consumption per 10,000 units per year. The total capacity of the station air compressor is 340mVmin. The total processing capacity of the refrigerator is 583. The above equipment can meet the design gas consumption. Requirements.

2.3 Economic Analysis and Comparison Conventional large-scale automobile companies use centrifugal air compressors with a large outflow. Because it has a large amount of gas output, continuous and stable investment, and low operating and maintenance costs. However, there is a surge in the process of low-load operation. When the production gas load is less than 70, there is a certain requirement for the gas consumption of the production process. The oil-free screw unit has a full-load regulation function, but the cost of the secondary cost is higher than that of the operating equipment. The same gas output price is more than double and the rotor-like operation year is about 40% of the cost of replacing the rotor. The operation and maintenance cost of the centrifuge is much lower than that of the screw unit. At present, the surge in the process of centrifugal low-load operation realizes full-load regulation to avoid the waste of a large amount of compressed air.

3 Conclusion Equipment selection is a comprehensive question. Based on the accumulated practical experience and the specific conditions of the company's equipment management, we decided to select the centrifugal air compressor unit.

At present, the equipment has been in good operation after two years of production and operation. It has achieved the effect of saving energy and easy maintenance in the investment province.
