Choose air compressor according to the needs of different industries and working conditions, there are corresponding standards. How to choose a suitable oil free air compressor?
1. First understand what is an oil-free air compressor and why use it?
Oil-free air compressor is not involved in the operation process of oil, whether it is oil-free piston machine or oil-free screw machine, the compressed air does not contain lubricating oil, so it is called oil-free air compressor, and it is used in industries with relatively high quality requirements for compressed air, such as laboratories, medical industry, mask production, etc.
Compared with the problem that oil-free compressors need to remove oil, oil-free compressors only need to remove water, do not need air compressor oil, and do not need to check lubricating oil at any time or deal with oil stains, which is also a cost saving. And oil-free screw air compressor is cleaner and more environmentally friendly than oil air compressor.
2. How to choose the appropriate parameters for selection?
(1) Determine the air working pressure required by yourself.
When buying an energy-saving air compressor, it is necessary to determine the pressure of the working condition. When the pressure is sufficient, the smaller the power, the more energy-saving.
(2) Determine the amount of exhaust required.
To determine the amount of exhaust per minute required by the equipment, select the appropriate. Can not blindly pursue large displacement, because the greater the displacement, not only a waste of electricity, but also a waste of money.
(3) Noise value.
Low noise air compressor, smooth output pressure without fluctuations, can reduce noise pollution. For example, laboratory matching and medical treatment all need low noise. Of course, oil-free silent air compressor/water lubricated oil-free air compressor can also be directly selected.
In the choice of oil-free air compressor to understand the above points, in order to better choose their own air compressor.
Now do you understand how to choose?
In the field of air compressor, there are not many manufacturers that can use real frequency conversion motors. Shanghai Granklin Group produces water-lubricated variable frequency air compressors. Through the use of permanent magnet motors and variable frequency controllers, it has achieved the effect of energy saving and emission reduction. General frequency conversion means can suppress frequent loading and unloading of equipment, and can also save a lot of power, improve reliability and reduce noise. If the air compressor uses frequency conversion, it can also stabilize the system pressure.
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.
View detailsFor medicine, food, semiconductor, chemical industry, fermentation and other industries, oil-free and clean compressed air must be the first choice. Oil-free oil-free screw air compressor, water-lubricated oil-free screw air compressor, oil-free scroll air compressor and oil-free centrifugal air compressor are common oil-free. Today, compare two types of oil-free screw air compressors-dry oil-free air compressors and water lubricated air compressors.
A biopharmaceutical company needs aerobic culture gas in the process of producing yeast culture, and the quality of the gas source required for biological fermentation is very high. However, customers do not understand the selection of air compressors, but have very high requirements for the quality of compressed air, and in order to avoid
The oil-free and water-lubricated single-screw compressors produced by Shanghai Granklin Group have unparalleled advantages in terms of gas quality, energy saving, easy maintenance and reliability, and are widely used in food and beverage, medicine and medical care, and precision manufacturing., Instrumentation, fuel cells, microelectronics, biology and other industries with extremely high gas demand.
View detailsThere 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.
View detailsWhich is better, single screw air compressor or twin screw air compressor? Let's analyze it. Principle: The single-screw air compressor uses a single-screw rotor to drive two symmetrically distributed star wheels to rotate, relying on the spiral groove and the inner wall of the shell to form a closed basic volume,
When the laboratory uses compressed air, it needs high-quality oil-free air. The "water-lubricated oil-free air compressor" produced by "Shanghai Grankering Group" can provide 100% oil-free "oil-free compressed air" for high-precision tests ". In the laboratory ventilation equipment we can refer to the following:
Several advantages of oil-free air compressor, as well as the difference between oil-free air compressor and oil-free air compressor. Specifically, look at their differences: oil and no oil in the air compressor generally refer to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm, so this oil content is used to distinguish the oil and no oil in the air compressor. There is also a full oil-free air compressor, it is not the use of oil lubrication, but the use of water lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.
Shanghai granklin group is a modern enterprise specializing in the design and manufacture of air compressors. it is mainly engaged in Shanghai air compressor, variable frequency screw air compressor, permanent magnet variable frequency air compressor, screw compressor, Shanghai screw air compressor, Shanghai air compressor, oil free air compressor.
