When discussing the allowable oil content of the oil injection screw air compressor, we must first make it clear that the traditional oil injection screw air compressor will inevitably contain a certain amount of oil in the compressed air due to the presence of lubricating oil during operation. However, there is a clear standard for this oil content, which usually requires no more than 3ppm (that is, no more than 3 mg of oil per cubic meter of compressed air) to ensure the purity and safety of compressed air.
However, the water-lubricated screw air compressor produced by Shanghai Granklin Group has completely subverted this tradition. As a representative of oil-free screw air compressors, it uses water as the lubricating and cooling medium, completely avoiding the contact between oil and compressed air, thereby achieving true oil-free compression. According to the ISO 8573-1 industry standard, the oil content of the compressed air of the oil-free air compressor must be less than 0.01 mg/m & sup3;, in order to reach the CLASS 0 level, is recognized as oil-free compressed air. The water-lubricated screw air compressor of Shanghai Granklin Group easily meets or even exceeds this standard, providing users with higher quality compressed air.
In addition, the water-lubricated screw air compressor also has many advantages such as environmental protection, energy saving, and low noise. There is no need to replace the lubricating oil during its operation, which reduces the risk and cost of oil pollution; at the same time, due to the larger specific heat capacity of water, the cooling effect is better, which helps to reduce energy consumption and improve equipment life. In addition, the water lubrication system also helps to reduce the operating noise and vibration of the air compressor, providing a quieter and more comfortable working environment for the production site.
To sum up, the oil content allowed by the oil-injected screw air compressor is clearly specified, but the water-lubricated screw air compressor produced by Shanghai Grankering Group provides users with a higher quality compressed air solution with its unique oil-free design and excellent performance. In the pursuit of high efficiency, environmental protection, energy-saving modern industrial production, oil-free screw air compressor will undoubtedly become the future development trend.
The working pressure of the air compressor is an important technical parameter, which is usually determined according to the specific application requirements and the design of the air compressor. Generally speaking, the working pressure range of the air compressor is wide, which can meet the needs of different industrial occasions. In common industrial applications
The pressure of the air compressor pipe depends mainly on the working pressure of the air compressor, that is, the pressure of the air compressor outlet. Generally, the pressure of 3~5KG is called low pressure, 7~13KG is called medium pressure, and more than 13KG is called high pressure. In addition, in the selection of air compressor piping
Oil-free compressed air is used in a wide range of applications, and the following are some of the main areas of application: Food and beverage industry: Oil-free compressed air is used for food and beverage filling, gas delivery and gas mixing process needs. Due to its oil-free nature, it will not
For traditional oil-lubricated air compressors, oil is a key component to ensure the normal operation of the compressor. It plays the role of lubrication, cooling and sealing. Therefore, in the regular maintenance cycle, the replacement of oil and oil filter is a common maintenance step. The oil will
The biological industry has strict requirements for compressed air, which are mainly reflected in the following aspects: Pressure: The air pressure at the outlet of the air compressor is usually required to be between 0.2 and 0.35MPa. This range can ensure that the compressed air is transported and used.
In the lithium battery factory, the dryness of the compressed gas is extremely strict, and the pressure dew point usually needs to be controlled between -40°C and -70°C to ensure the safety of battery production and product quality. The following is a detailed explanation of this requirement: the core of the 1. dryness requirement refers
How long does the air compressor need to be maintained? 1.500 hours: When the air compressor runs for 500 hours, the oil filter element and air compressor lubricating oil will be changed for the first time after the new machine is used. Remove the air filter for cleaning and blow it out with low-pressure compressed air
The reason why the compressor is used in coalbed methane is that the compressor plays a vital role in the mining, transportation and utilization of coalbed methane. The following is a detailed explanation of the use of CBM compressors: The basic characteristics of 1. CBM CBM, also known as coal mine gas
A very important point is that the water lubricated air compressor adopts single screw compression, which can make gas without oil. If you need to purchase water lubricated air compressor, permanent magnet air compressor, variable frequency air compressor and oil-free air compressor, please contact Mr. Hu of Shanghai granklin group at 13918023456
View detailsAccording to the different compression stages, the screw air compressor is mainly divided into two types: single-stage compression and two-stage compression. They have their own characteristics in structure, working principle, performance and applicable scenarios. In terms of structure, the single-stage screw air compressor adopts a one-stage compression process, that is, the gas in the screw.
