First, we should consider the exhaust pressure and the quantity of the exhaust.

Based on the national standard, the exhaust pressure of general purpose atmosphere compressor is 0.7 MPa (7 atmospheric pressure) and the old regular is 0.8 MPa (8 atmospheric pressure). Because the style operating pressure of pneumatic equipment and wind machinery is 0.4 Mpa, the functioning pressure of atmosphere compressor can fully meet up with the requirements. If the air compressor utilized by the consumer is bigger than 0.8MPa, it must be specially manufactured. The method of forced pressurization can not be adopted to avoid accidents.

The size of the exhaust can be one of the primary parameters of the air compressor. Choosing the air volume of the air compressor should match its exhaust volume and leave a 10% margin. If the air volume is large and the air flow compressor exhaust volume is small, when the pneumatic equipment start, the exhaust pressure of the surroundings compressor will be significantly reduced, but the pneumatic tools can not be driven. Of training course, it is also wrong to pursue large exhaust capacity blindly, since the bigger the exhaust capacity, the larger the engine allocated by the air compressor, not only the higher the purchase price, but also a waste materials of buying funds, and the utilization of power and energy will become wasted.

Consider the mixture of gas fields and conditions.

If the use of air space is narrow, it should be vertical; if there is a long-distance switch in the use of air (more than 500 m), mobile type is highly recommended; if the utilization of electricity can’t be utilized, diesel engine generating type ought to be selected; if there is simply no circulating drinking water in the use of occasions, air-cooled type ought to be chosen. In the air-cooled and water-cooled cooling modes, many users have an incorrect proven fact that water-cooled is great, but in fact it isn’t. The air-cooled type accounts for more than 90% of the tiny compressors in the home and abroad. This is since the air-cooled type is simple in design no water source is needed in use. There are four fatal shortcomings of water-cooled compressor: it will need to have a complete higher and lower water system with large expense; water-cooled cooler has brief life; it is easy to freeze the cylinder in winter season in the north; it will waste a whole lot of water in normal operation.

Then consider the compressed quality of air.

Generally, compressed air made by air compressor contains a particular quantity of lubricating oil and water. In some instances, it is prohibited from essential oil and water. At the moment, attention ought to be paid not merely to the selection of compressor, but also to the addition of auxiliary devices when Tractor Gear Reducers necessary.

Lastly, it really is to expand the knowledge of reference.

1. Stability: With the solid rise of China’s economy and the continuous emancipation of the minds of all types of manufacturers, manufacturers from coast to coast are busy with creation work. Along the way of production, air flow compressors, which play a significant role, are often completely loaded and operate all-weather. In the full production of factories, surroundings compressor gas production is unstable, which is a very troublesome thing, often will bring incalculable losses. Therefore, when we purchase atmosphere compressors, the 1st criterion is the stability of air compressors. At present, some high-end brands both in the home and abroad can meet this necessity. With the mature technology of variable frequency surroundings compressor, it could be said to meet this requirement.

2. Gas creation: The second is gas creation. Some enterprises possess very good quality of gas. For instance, in the pharmaceutical sector, basically the gas they need is oil-free. In this respect, it is still based on the enterprise’s very own situation. If the enterprise includes a high demand because of this, then it’s been a long period to purchase more well-known devices. If the demand is not high, it depends on other situations. As the near future development trend of the surroundings compressor industry, the adjustable frequency air compressor is still very excellent in gas production, since the variable frequency surroundings compressor includes a prominent characteristic of tracking gas creation, and at exactly the same time the gas quality created is very considerable.

3. Power consumption: That is a relatively important place as well as the focus of dialogue, because atmosphere compressor, as a basic equipment, is generally managed all-weather, and surroundings compressor itself is an extremely power-consuming equipment, the general manufacturer of air compressor power consumption accounts for 20-30% of the full total plant power usage. If effective control, the effect is very obvious. Many domestic enterprises are actually pursuing the bottom price. In fact, underneath price is rather one-sided. For general production enterprises, the price of surroundings compressor only makes up about 5% of the total cost of atmosphere compressor, 9% of the maintenance and labor costs, and 86% of the full total cost of electric power. Therefore, considering the last expenditure, the frequency transformation air compressor must be much lower compared to the ordinary air compressor. Frequency conversion air compressor is only the first investment, but invest the the electricity price into account, you really can calculate a bill. Today, the overall energy-saving amount of regularity converter air compressor is very objective, and the domestic professional frequency converter air compressor, its power-saving rate is really as high as 30%, usually within a season can recover the difference. Therefore, when choosing surroundings compressor, choosing a good variable frequency air flow compressor is really the very best solution to the problem of power consumption.
