oil free air compressor which brand is good?
There are many brands of oil-free air compressors on the market, and the water-lubricated oil-free air compressors with a good reputation in China are "Shanghai Granklin Group". Oil-free air compressor manufacturers need long-term continuous technical accumulation, because it is a very important part in the after-sales of air compressors. If it is not a long-term operation of oil-free air compressors, it is difficult to solve the problem immediately.
A good brand of oil-free air compressor is the need to improve the certificate, good reputation in the market, high-quality after-sales service. Integrated operation products, with the best products and services to customers with high-quality experience.
1. Screw compressor
screw compressor is also called screw compressor. In the 1950 s, oil-injected screw compressors were used in refrigeration devices. Due to their simple structure and few wearing parts, they can have low exhaust temperature under large pressure difference or pressure ratio conditions. They are not sensitive to a large amount of lubricating oil (often called wet stroke) contained in the refrigerant, and have good air delivery adjustability. They quickly occupy the use range of large-capacity reciprocating compressors, and continue to extend to the medium capacity range, widely used in refrigeration, refrigeration, air conditioning and chemical processes and other refrigeration devices. In the industrial field is widely used, as well as medical and pharmaceutical use is also essential, and must use oil-free air compressor.
2. Centrifugal compressor
A centrifugal compressor is a vane rotary compressor (I. e., a turbine compressor). In the centrifugal compressor, the gas pressure is increased by the centrifugal force action given to the gas by the impeller rotating at a high speed and by the diffuser action given to the gas in the diffuser passage.
Early, because this compressor is only suitable for low, medium pressure, large flow occasions, and not for people's attention. Due to the development of the chemical industry, the establishment of various large chemical plants and refineries, centrifugal compressors have become the key machines for compressing and transporting various gases in chemical production, and occupy an extremely important position. With the achievements of gas dynamics research, the efficiency of centrifugal compressors has been continuously improved, and due to the successful development of high-pressure seals, small-flow narrow impellers, and multi-oil wedge bearings, a series of problems in the development of centrifugal compressors to high-pressure and wide-flow ranges have been solved, so that the application range of centrifugal compressors has been greatly expanded, so that they can replace reciprocating compressors in many occasions, and greatly expand the application range.
3. Reciprocating piston compressor
is the development of various types of compressors in the earliest one, 1500 BC China invented the wooden bellows for reciprocating piston compressor prototype. At the end of the 18th century, Britain made the first industrial reciprocating piston air compressor. Labyrinth compressors began to appear in the 1930 s, followed by various oil-free compressors and diaphragm compressors. In the 1950 s, the size of the large reciprocating piston compressor was greatly reduced, and the single machine was multi-used.
The piston compressor has a long history of use and is currently the most used compressor in China. Due to its wide pressure range, it can adapt to a wide energy range. It has the advantages of high speed, multi-cylinder, adjustable energy, high thermal efficiency, and suitable for various working conditions; its disadvantages are complex structure, many wearing parts, and maintenance cycle Short, sensitive to wet stroke, pulse vibration, poor operation stability.
Therefore, in the choice of air compressor brand and series, it is a better choice to choose the "water lubricated oil free air compressor" produced by Shanghai granklin group.
Now it has entered the summer that people love and hate, and the temperature in many places has risen to above 30°C. In the face of the hot summer, screw air compressor temperature is too high by what reason? Summer, screw air compressor is more common fault is scattered
It is very difficult to make a brand, from the brand name to the registered brand, as well as the design of the product LOGO. The most important thing is whether the products to be produced by the enterprise have enough technology accumulation to complete the quantitative change and qualitative change of the enterprise brand. Shanghai granklin group in continuous research and development of products, improve products at the same time there are various patent certificates, such as all kinds of "water lubricated oil-free air compressor" certification, in the air compressor brand we have always been serious, dare not have the slightest slack.
View details[Water-lubricated air compressor] As the main product of Shanghai Granklin Group, it has achieved "100% oil-free compressed gas" in the field of oil-free compressed air ". What are the advantages and disadvantages of screw air compressor compared to other types?
1. Check whether the fuse is burned and blown, causing the circuit to fail and cannot be powered on. 2. Motor failure. The insulation layer is aged or the temperature is too high, the insulation layer is melted, so that the insulation effect is insufficient and leakage occurs. 3. The motor is locked and overcurrent. Not enough lubricant,
The main functions of air compressors in the food industry are embodied in the following two aspects: (Granklin water-lubricated air compressors, food factories use 100% oil-free) 1. Avoid contamination of equipment and food. Because food production often depends on natural fruits, the shelf life of these fruits is very short, which has strict requirements on the air environment of food production equipment and products.
There must be internal wear and aging during the long-term operation of the screw air compressor. Therefore, it is very important to regularly maintain and replace consumables in time. Most users are not very clear about consumables. The following is a detailed introduction of the consumables of the screw air compressor. What are the screw air compressor consumables we often say?
View detailsOil-free air compressor theoretically no clearance volume, single capacity, ideal isothermal compression, due to the good thermal conductivity of water, lubricating water into the compression chamber, the temperature will drop to 45 ℃, close to the suction temperature. Oil-free: water to replace oil, lubrication, cooling, sealing, noise reduction of the four effects, to provide 100 oil-free air, no pollution, the discharge of water without special treatment, in line with environmental requirements.
View detailsWith the increase in equipment demand, the water-lubricated oil-free air compressor industry is a supporting industry in many fields, so its role is very important.
Air compressor is the abbreviation of "air compressor. As early as 1640 AD, the first (mechanical) vacuum pump made in Germany, now, with the improvement of technology, air compressors have been busy in all walks of life, such as food, tobacco and other metallurgy, petrochemical, chemical fiber, pharmaceutical and so on.
Why does the compressed gas of the screw air compressor produce water? How can we efficiently remove the moisture in the compressed gas of the screw air compressor? Is there really an oil-free and water-free screw air compressor? People in the workshop see this question. As a member of the air compressor industry, it is more reasonable for us to answer this question.
