In the field of electric air compressor, the design of oil and oil free is not only related to the technical level, but also directly affects the air quality and environmental protection standards. The water-lubricated screw air compressor produced by Shanghai Granklin Group has become a leader in the market with its unique oil-free design concept.
Traditional oil-based air compressors rely on lubricating oil to reduce friction, reduce wear and improve equipment operating efficiency. However, this process will inevitably produce oil mist and oil pollution, the quality of compressed air pollution. This is undoubtedly a big challenge for industries with high air quality requirements such as food and medicine. In contrast, Granklin Group's water-lubricated screw air compressors use pure water as a lubricant, which completely avoids the pollution of compressed air by lubricating oil and ensures the purity of the air.
In addition, the high heat capacity and good thermal conductivity of water make the cooling effect of the water-lubricated screw air compressor more excellent, effectively preventing the equipment from overheating and performance degradation. At the same time, this design also simplifies the maintenance process and reduces the maintenance cost. Since there is no lubricant as a consumable, users do not need to regularly replace the lubricant and clean the oil filter, which greatly saves time and cost.
The water-lubricated screw air compressor produced by Shanghai Granklin Group not only meets the demand for pure compressed air in high-end industries, but also provides strong support for the sustainable development of enterprises. Its oil-free, efficient and environmentally friendly characteristics lead the new fashion of the air compressor industry and are ideal for the pursuit of high-quality air compression solutions. In the future, with the increasing awareness of environmental protection and the continuous improvement of air quality requirements in various industries, water-lubricated screw air compressors will undoubtedly play a more important role.
Permanent magnet variable frequency air compressor and variable frequency screw air compressor have their own unique features in function and application. Which is better to use needs to be judged according to actual needs and use environment. The following are several comparative dimensions between them: energy efficiency: permanent magnet variable frequency air compressor
In the aluminum processing industry, air compressors play a vital role. The following are the main uses of air compressors in aluminum processing: 1.-driven pneumatic tools and equipment pneumatic tools: air compressors provide power for various pneumatic tools used in the aluminum processing process, such as air
There are significant differences between oil-free compressors and micro-oil compressors in many aspects, which are mainly reflected in the working principle, compressed air quality, operating costs, maintenance requirements, performance and so on. The following is a detailed analysis of the difference between the two: 1.
Air compressors are widely used in many industrial and commercial fields. The following are some types of companies that need to use air compressors: Manufacturing: In manufacturing, air compressors are widely used in various processes, such as pneumatic tools, automation equipment, packaging machinery
The correct maintenance cycle of the screw air compressor needs to be determined comprehensively according to multiple factors to ensure the long-term stable operation and efficient performance of the equipment. The following is a rigorous analysis of the screw air compressor maintenance cycle: 1. basic maintenance cycle Generally speaking, the basis of screw air compressor
Oil-free compressed air refers to compressed air that does not add any oil lubrication during the compression process using an air compressor. This compressed air has the characteristics of high quality and high cleanliness, and is especially suitable for areas with high air quality requirements. No oil pressure
The time that the air compressor can run for a long time depends on many factors, including the type of air compressor, the working environment, the load situation, and the maintenance. Generally speaking, the screw air compressor can run for a long time after replacing the three filters, or even
To determine the size of an air compressor that needs to process 6 cubic meters of air per minute, we must first understand the main parameters of the air compressor, that is, its exhaust volume. Exhaust volume refers to the volume of air that the air compressor can discharge per unit time. The topic has already told us, every point
The oil content of compressed air is usually expressed in ppm (parts per million) and milligrams per cubic meter (mg/m & sup3;), both of which are used to measure the degree of oil pollution in the air. ppm is a unit of volume concentration, which refers to the ratio of oil volume to total air volume per million;
The air compressor can use both electricity and oil, which mainly depends on the type and purpose of the air compressor. Electric air compressors that use electricity are one of the most common types. They work by driving a compressor with an electric motor. This air compressor is usually used for continuous
