There are two basic types of screw air compressors: oil-injected and oil-free.
Oil-injected (or oil-immersed) screw air compressors use oil to lubricate the screw unit and ensure its smooth operation. The oil also helps cool the compressed air and prevents the equipment from overheating. After compressing the air, an oil separator is used to remove the oil. A small amount of oil (oil residue) may remain in the compressed air, which can be further reduced using in-line filtration. Oil-injected compressors are the most common type of screw air compressor and are suitable for most applications.
Oil-free (or oil-free) screw air compressors are water-lubricated with a single screw. Air inhalation of the atmosphere without oil can ensure the cleanliness of the gas. Oil-free screw air compressor compressed gas is very clean air, do a hundred percent oil-free.
Compressed air quality standards for pharmaceutical use shall meet international standards, pharmacopoeia specifications and industry best practices at the same time. The key control parameters and implementation requirements are as follows: 1. core standards are based on ISO 8573-1:2010 (Compressed Air Quality Grade) Solid Particles: Grade 1: Particles
Permanent magnet air compressor is not a brand, but a type of air compressor. It refers to the use of permanent magnet synchronous motor to drive the compressor rotor, and adjust the power frequency of the compressor through frequency conversion technology to adjust the output pressure, flow and power of the compressor
Variable frequency air compressor is good? -- In the industrial production, the air compressor is an important equipment, its performance directly affects the production efficiency and operating costs of enterprises. In recent years, with the technology
Usually screw compressors need to be maintained after more than 2000 hours of operation. Air compressor oil is an essential part of the maintenance process, while air compressor oil has poor quality, many impurities and high viscosity. Easy to cause, air compressor oil shortage. The bearing shell is displaced so that
It takes tens to hundreds of hours for the oil injection machine pipeline to clear the oil, and regular maintenance is required in the follow-up. There is no oil in the water-lubricated oil-free pipeline. It is only necessary to solve the water problem.
The air blown by the air compressor can be divided into oil and oil-free. The main difference between them is the oil content in the compressed air. During the compression process of the oil air compressor, the lubricating oil will be in direct contact with the air, so the compressed air will contain a certain amount
The air compressor room of ordinary hospitals, especially those that have already used water to lubricate the air compressor, because the combustion risk caused by oil is removed from the root, it is generally not necessary to set up explosion-proof fans, and it is enough to do a good job of ordinary ventilation and heat dissipation. However, if the computer room is in a special environment with flammable and explosive substances, it is necessary to set up explosion-proof fans, and at the same time, a series of safety measures such as gas monitoring and anti-static should be done.
Explosion-proof air compressors are special equipment designed for flammable and explosive environments. Its core value is to reduce the risk of fire or explosion through explosion-proof technology. The following is a detailed description based on industry characteristics and technical specifications: 1. Core Application Industries Oil & Gas
The quality grade of compressed air in common factories is usually evaluated according to the impurities and moisture content, and the common grades include industrial grade, medical grade and food grade. The following is a specific introduction to these grades: Industrial Grade Features: Industrial Grade Compressed Air Applicable
As an important industrial equipment, air compressor has a wide range of application scenarios. The following is a description of the use scenario of the air compressor, which is classified and summarized according to different industries and applications: 1.
