How to choose and buy the silent oil-free eisens air compressor accurately

Source: essens air compressor Time of publication: June 10, 2019 tag: Small in large

1. Selection before purchase. If you choose the equipment with good quality and suitable requirements, you will have a lot less poverty.

(1) the quality of some brands of foreign companies is generally reliable. However, under such circumstances, due to the cost of production and transportation, the price of some foreign brands is always high, which is not the first choice of ordinary companies and individuals; Moreover, because of the different brands and quality of domestic companies, the quality of similar products has improved rapidly. Some manufacturers have no difference in technical ability from foreign countries, and some even have crossed over foreign countries. It is suggested to consult with Kaixing before purchasing, or use the key words such as "silent oil-free air compressor", "silent oil-free air compressor" and "medical dental equipment" in the collection. www.srtyasuoji.com

(2) at first, the air compressor model should be selected according to the air flow under the rated pressure of the equipment. The best flow rate of the selected air compressor is slightly larger than the required flow rate, so as to prevent the leakage of some pipeline joints, resulting in the flow not keeping up with the demand, so that the pressure can not reach the demand. The gas flow unit usually has m3 / h (cubic meter / hour) and L / min (liter / minute). 1m3 is 1000L. Pressure is also a key factor. The maximum exhaust pressure of air compressor must be consistent with the pressure required by equipment. If it is small, it can not meet the demand of equipment. If it is large, the purchasing cost will rise. Pressure performance unit usually has bar, kg / cm2 (commonly known as kg pressure). In addition, the rated power of air compressor is not the better, but to choose a smaller power when the flow and pressure meet the requirements, so as to save unnecessary capital expenditure on electricity.

(3) with the progress of people's familiarity with health and environmental protection requirements, many equipment work more and more closely, which puts forward higher requirements for the air compressors which provide air source for these equipment, and the utilization scope of oil-free air compressor is becoming wider and wider. Www.srtyasuoji.com please confirm the detailed requirements of the equipment on the quality of gas source and installation environment. If the requirements are not high and do not care about whether the gas is oil-free, you can choose some popular industrial tightening machines with high noise ratio and lubricating oil molecules in the exhaust air according to the principle of cost saving; otherwise, you need to purchase silent oil-free air compressor.

2. At present, the main engine of silent oil-free air compressor adopts micro to reactivate plug type compressor. If it is not of this type, it can be determined that this kind of air compressor does not belong to the silent oil-free air compressor, and the air quality can not meet the requirements of the silent oil-free air compressor.

3. Whether the technical parameter identification is complete and accurate. According to the international general practice, the parameters identified include metric units and American units. Want to buy parameter identification is normal and correct. The simple parameter identification of the manufacturer is because there is no relevant testing equipment, so it is impossible to test such technical parameters, or some parameters can not reach the general technical standard. Therefore, it is suggested that the user should ask the manufacturer to provide detailed parameters for accurate selection.

4. Whether the host is certified by the process industry product license. At present, most of the manufacturers have passed some foreign certification such as CE, but because they are not in line with the domestic industry standards, they have not passed the compulsory certification at home, so there may be risks in using them.

5. Convenient selection of after-sales manufacturers. We should consider from three aspects: the manufacturer's general knowledge of the products; the accessories; and after-sales maintenance. Because most domestic oil-free air compressor manufacturers are small in scale and small in batch production, which leads to excessive competition in the same industry, making the price lower and lower, but the quality also declines.
