How to buy mute oil-free air compressor head
1. Choices before purchase. It will be much less troublesome to choose the one with good quality and suitable for the requirements of the equipment.
(1) some brands of foreign companies are generally reliable in quality, but usually their production and transportation costs lead to higher prices, which are unacceptable to enterprises; However, other Chinese Air Compressor Companies' pursuit of brand and quality is changing with each passing day, and the quality of similar products is constantly evolving, so the quality is guaranteed. Some manufacturers are basically no different from foreign countries in terms of R & D capabilities, and some have reached the level of foreign countries.
It is recommended to consult with peers before purchasing or search and compare on the Internet with keywords such as "silent oil-free air compressor head", "silent oil-free air compressor head" and "dental instruments".
⑵ the model of the air compressor should be selected according to the air flow under the rated pressure of the equipment. The flow of the selected air compressor needs to be slightly larger than the required flow, which suppresses the leakage of some pipe joints, causing the flow to fall behind, so the pressure cannot meet the demand. The units of gas flow are usually m3/h (cubic meter / hour) and l/min (liter / minute).
1m3 equals 1000L. Pressure is also a key factor. The upper limit exhaust pressure of the air compressor is consistent with the pressure required by the equipment. If it is small, it cannot meet the equipment demand, and if it is large, the purchase cost will rise. Pressure is usually expressed in bar, kg/cm2 (commonly known as kilogram pressure). In addition, the rated power of the air compressor is not the greater the better, but to choose a smaller power when the flow and pressure meet the requirements, which can save power resources.
⑶ with the increase of people's awareness of health and environmental protection, the workmanship of many equipment is becoming more and more precise, which puts forward high-level requirements for the air compressors that provide air source for these equipment. Therefore, the application range of oil-free air compressors is becoming wider and wider. Please first confirm the specific requirements of the equipment for the quality of the air source and the placement environment. If the requirements are not high and you don't care whether the gas is oil-free, you can consider selecting some ordinary industrial compressors with high noise and lubricating oil molecules in the exhaust air based on the principle of cost saving; Otherwise, we need to purchase mute oil-free air compressor.
2. At present, the main machine of silent oil-free air compressor adopts micro reciprocating piston compressor. If it is not this type, it can be judged that this kind of air compressor does not belong to silent oil-free air compressor, and the air quality cannot meet the requirements of silent oil-free air compressor.
3. Whether the parameter identification of the air compressor is available and correct. Parameters identified according to foreign conventions include metric units and American units. It depends on whether the selected parameter identification is accurate. Manufacturers with simple parameter identification are unable to do such scientific and technological parameter testing because there is no relevant testing equipment, or some parameters cannot meet the general scientific and technological standards. Therefore, it is recommended that users ask manufacturers to provide detailed parameters in order to make correct choices.
4. Whether the host has passed the industrial product license verification. At present, most manufacturers have passed the first CE verification abroad, but because they do not conform to China's industrial standards, they have not passed the relevant verification in China, so there may be risks in use.
5. Choose manufacturers with convenient after-sales service. Service should be considered from three aspects: the manufacturer's service for product knowledge; Service for accessories; Service for after-sales maintenance.
Most of the manufacturers of oil-free air compressor heads in China are small in scale and small in batch production, which leads to excessive competition in the industry, making the price lower and lower, but the quality also decreases.
