Oil-free air compressor has two compression modes, water lubricated oil-free air compressor and dry oil-free air compressor. We need pure oil-free compressed air. Most of them purchase equipment in these two schemes. Water-lubricated air compressors are mature enough. Shanghai Granklin Group mainly produces water-lubricated air compressors.
1, to consider the safety of oil-free air compressor operation.
Oil-free air compressor is a kind of machine with pressure operation, which is accompanied by temperature rise and pressure, and the safety of its operation should be put in the first place. The state implements the standardized "two certificates" criterion for the production of compressors, that is, the compressor production license and the pressure vessel production license (gas tank). Therefore, when purchasing compressor products, it is necessary to strictly check the "two certificates". Usually, the product quality assurance system of the certified manufacturer is perfect and will not present major quality problems. Even if there are some problems, the manufacturer will be responsible for the three guarantees.
2, to consider the compressed air quality.
Generally, the compressed air produced by the air compressor contains a certain amount of lubricating oil and a certain amount of water. In some cases, it is forbidden to oil and water. At this time, it is not only necessary to pay attention to the selection of the compressor, but also to increase the auxiliary equipment when necessary.
Solution: First, choose water-lubricated air compressor. This compressor host basically does not contain oil, and its air compressor host uses water as a lubricating substance to replace the lubricating oil of the traditional air compressor.
The gas compressed by the main engine of the water lubricated air compressor and the back-end cold dryer can remove water, so that the air compressed by the compressor contains neither oil nor water, and the oil content in the compressed air is below 5ppm, which can meet the process requirements.
3. The displacement is one of the main parameters of the water-lubricated oil-free air compressor. The gas volume of the air compressor should be matched with the required displacement, and a margin of 10%-20% should be left. If the air volume is large and the air compressor exhaust volume is small, the pneumatic tool is started, the exhaust pressure of the air compressor will be greatly reduced, and the pneumatic tool cannot be driven. Of course, it is also wrong to blindly pursue large exhaust volume. As the larger the exhaust volume, the larger the motor equipped with the compressor, not only the price is high, but also the purchase funds are wasted. In daily production and use, electricity will be wasted and energy consumption will be increased.
Through years of after-sales maintenance practice, the author has a systematic understanding of the daily maintenance of the screw air compressor. The following provides you with some references. 1. the preparation work before starting. Prepare the post-treatment equipment before turning on the power, and check the cooling dryer.
It is recommended that you consider these comprehensive factors when buying air compressors: price, use, gas production, and after-sales service. Imported brands are more expensive than domestic air compressors, but the cost performance of domestic brands and
Medical air compressor mainly provides sufficient and clean air source for medical and health care equipment that needs air source. It is suitable for dental treatment equipment, oxygen generator equipment, ventilator equipment, medical pneumatic equipment, etc. The working principle of medical air compressor is a miniature oil-free air compressor. The piston air compressor is traditionally used. However, in view of the large oil content of the piston air compressor, the air cleanliness is not high.

By compressing the gas in a variable volume, the volume of this part is reduced and the pressure is increased. The core structure of the compressor is finished by a special machine tool and consists of a screw with six spiral grooves, with one on both sides.
The water lubricated air compressor produced by Shanghai granklin group belongs to screw type in the air compressor category. Screw type air compressor is divided into twin screw and single screw. The water lubricated air compressor uses single screw compression. Under the condition of the same power consumption, the single screw gas production is more sufficient. Air compressors are classified according to the principle. Air compressors can be divided into two categories: rate type and capacity type. The gas machine is divided into: rate type; Capacity type; Capacity type is divided into tube type and reciprocating type; Tube type: rotor type; Screw type; Slide built-in type.

View detailsAir compressor is the main equipment in industrial production. The production of all walks of life is inseparable from air compressor. With the development of science and technology, many industries have put forward higher requirements for air compressor. They require the air compressed by air compressor to be cleaner. In order to achieve this effect, we need to use more functional air compressor equipment, which is oil-free screw air compressor. So how much do you know about oil-free screw air compressor?
An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are of the reciprocating piston type. As an important form of energy generation, air compressor is widely used in all aspects of life and production. In particular, single-screw air compressors are widely used in machinery, metallurgy, electronic power, medicine, packaging, chemical, food, mining, textile, transportation and many other industrial fields, becoming the mainstream product of compressed air.
