Air compressors with oil and without oil are not absolutely good or bad. Their use occasions are different from those suitable for working conditions. If they are used for purging, mechanical processing, manufacturing and power use, it is OK to choose air compressors with oil and micro oil. However, oil-free air compressors must be used in some occasions, such as food, medicine, precision instruments and other industries. Oil-free air compressors are cleaner and more environmentally friendly than oil-free air compressors to some extent, but oil-free air compressors are more expensive than oil-free air compressors and have higher maintenance costs.
In addition to the price, oil-free air compressor and oil air compressor has the following differences:
1. The oil content is different. Generally, the oil content of the oil machine is larger, and the oil content of the oil machine is 0.01ppm, so this oil content is used to distinguish the air compressor with oil and without oil. There is also a full oil-free air compressor, which uses water to lubricate the head of the air compressor, so the final discharge gas does not contain oil, which is called a full oil-free air compressor.
2. The structure is different. Whether it is an oil-free piston machine or an oil-free screw machine, a large amount of high temperature will be generated during the operation. The participation of oil in the air compressor will take away the high temperature generated during the compression process of the air compressor, thereby Cooling the machinery. The oil-free water lubrication air compressor uses water to replace the oil to solve the high temperature in the air compressor compression process, so as to achieve the purpose of oil-free compression.
Water-lubricated air compressors can use tap water, but the following points need to be paid attention to: Water quality requirements: The water quality of tap water needs to meet the requirements of water-lubricated air compressors. Generally speaking, it is necessary to ensure that the pH, salinity, hardness and impurity content of the water are within a certain range.
shanghai granklin group detailed air compressor products in the air compressor in the market, permanent magnet frequency conversion screw machine because of its high efficiency, energy saving characteristics and widespread concern. Among the many air compressor manufacturers, Shanghai Granklin Group
In the air compressor industry, oil-free screw air compressor is more and more favored by the market for its high efficiency and environmental protection. Among the many oil-free screw air compressor manufacturers, Shanghai Granklin Group stands out by virtue of its water-lubricated screw air compressor products.
In a semiconductor factory, compressed air is not a supporting role, but one of the three foundations that are juxtaposed with electricity and light. Purge, drive, flow control, cooling, everywhere to be used.
Oil-free water lubrication screw air compressor generally adopts single screw design. The main feature of this design is the use of pure water as the sealing and lubrication medium, thus ensuring that the output of compressed air is pure and oil-free. Due to the role of water lubrication and sealing, this type of air compressor
Frequency conversion screw machine is a kind of high efficiency and energy saving equipment, which is widely used and involves many industrial fields. The following is a detailed explanation of the main functions and uses of the variable frequency screw machine: Working principle: The variable frequency screw machine is mainly composed of screw compressors, condensers,
The rated pressure and working pressure of the air compressor are the key parameters for selection and use, and their range varies with equipment type and application scenario. The following is a detailed description: 1. rated pressure definition: air compressor at rated speed, rated conditions under continuous operation of the highest exhaust
If the oil-free air compressor does not stop and continue to run, the following situations may occur: The temperature is too high: During the long-term operation of the oil-free air compressor, the internal temperature of the machine will rise due to the pressure generated by friction and compression. Excessive temperature will damage the inside of the machine
Air compressors are widely used in many industries. The following are some major industries and their specific application scenarios: Industrial manufacturing: Automobile manufacturing: Air compressors are used for parts assembly, sealing, molding, and pneumatic tools (such as pneumatic Wrenches, pneumatic drills) power source
As an important equipment in industrial production, the danger of air compressor is mainly reflected in the following aspects: 1. explosion danger internal failure or unreasonable design: heat will be generated in the process of air compression. If the compressor fails or the design is unreasonable, the heat cannot
