After watching the circle of friends, I was thinking about a question: how are friends with you? No one is a customer, the customer? Seeing the time waits for no man, said that on 2016, at the end of the year, the beginning of the year the target is now finished? I am embarrassed to see. Say that this year the market is really bad, less than last year, less than the previous year, the circle of friends who said that the people around also said. Why? Air compressor industry as a newcomer, I also want to, but also in a serious analysis and judgment of the current market.

Lucky here in the circle of friends to share with you today the sound, view may be a little one-sided, fool's opinion please predecessors to the exhibitions.

When it comes to air compressors have to say that the supporting post-processing equipment. Gas storage tank, also known as pressure vessels, to the current market classification, the majority of simple pressure vessels. Gas cylinder supporting air compressor has been sold, is a more common sales model, the pros and cons of the industry environment is determined. Looking at the year-end report, I don't think I can do this. Recently we continue to participate in a number of industry activities, to participate in a number of energy-saving research, deep feelings. It's not wrong to stay with our predecessors, but it's too slow. We have to find a way to break through. By analyzing the two sales opportunities, guiding users to improve the air condition, increase at the end of the buffer tank, improve previous piston air compressor gas tank not situation, improve the air compressor power so as to make substantial contribution to energy saving.

I believe you peer understanding of design specification, tank technical conditions and material application, than I should be deep and clear, but I still want to remind you that the gas tank of the most simple and basic function we still need to understand. The gas tank in the compressed air industry is devoted to the storage of compressed gas equipment, but also to stabilize the system pressure, the gas tank under pressure can be divided into high-pressure gas tank, low pressure gas tank, pressure tank. The gas tank according to different materials: carbon steel, low alloy steel storage tank storage tank, stainless steel storage tank. Gas storage tank (pressure vessel) generally consists of cylinder, head, flange, nozzle, sealing elements and bearings and other parts and components. In addition, the utility model is provided with a safety device, a meter and an inner part to complete different production processes. In addition, there is a certain risk of gas storage tank, so the production and utilization of gas storage tank must have configuration requirements and maintenance requirements.

Gas storage tank is an important equipment in the gas supply system:

1, to provide a larger system capacity, to extend the air compressor "start stop" or "loading unloading" cycle, reducing the switching frequency of electrical equipment and valves.

2, further cooling air separation and removal of impurities in the air, compressed water pollution, reduce the work load of network downstream other postprocessing equipment, make all kinds of gas equipment to obtain the required quality of the gas storage tank; a miniature air compressor with and is used to do the installation and other accessories of the compressor body frame.

3, storage capacity, on the one hand to solve the system within a short time the possible consumption contradictions, on the other hand, failure or other unexpected events in the compressor as a temporary emergency.

4, the gas tank can eliminate or weaken the pulsation of piston air compressor output flow, to stabilize the air pressure, to ensure continuous and stable output flow; avoid using gas equipment with gas is not stable due to air compressor working efficiency and frequent load change. This will not only affect the efficiency and service life of the compressor, but also will lead to insufficient supply of gas, affecting production. The utility model can be used to replenish and adjust the air quantity in time, and plays the role of balance and buffering. In particular, in the case of frequent changes in gas load, large capacity of the gas tank should be selected to regulate and balance the gas supply capacity. Do not set up the gas tank in the air compressor station, also need to increase the buffer tank in the gas and in the end, to solve the actual needs of the user can also increase sales.

The calculation formula of gas storage tank can be selected

V=N * Q/ (p+1) m fand

V - tank volume fand M

Q: air compressor exhaust m fand /min

P - air pressure fand kgf/cm

N - initial coefficient, generally take 1~3 (in order to save energy, as far as possible the choice of large capacity gas tank)

How to choose a suitable gas tank? In general, air compressor gas can be calculated, but also very clear, but with how much gas tank is appropriate? According to experience, the general air compressor and gas storage ratio of about 3:1 is more appropriate. For example, if the air compressor exhaust volume is 3 cubic meters, then the gas tank with more than 1 cubic meters is more appropriate. Of course, with 0.6 cubic meters of gas tank can also be used, but the gas is too small, so that the air compressor is easy to frequent loading and unloading, reducing the service life of air compressor. It would be better if conditions permit a larger gas tank, but this increases the cost of the purchase.

Air compressor gas storage market in the end how? The opening of the incremental environment or the downturn of the downstream process, the decision of the gas storage industry how to choose and how far. In June 21st, the national development and Reform Commission, Ministry of industry and information technology, the National Energy Bureau jointly issued three "China 2025 energy equipment manufacturing plan" notice: at the same time, the central CCTV2 evening "market analysis room" program focuses on high-end energy-saving equipment, invited the general manager, executive Silver River Securities Research Department Chinese machinery industry chief analyst Wang Huajun, including compressor,
