Technical Analysis of Oil-free Screw Air Compressor
oil-free screw air compressor is a kind of equipment which adopts oil-free lubrication technology and realizes air compression through the meshing movement of screw and star wheel. Its core is to replace traditional lubricating oil through physical structure design and water lubrication system to ensure the purity of compressed air and realize efficient and stable operation. The following is a professional analysis from the three dimensions of technical principles, performance advantages and application scenarios:
compressor structure
the equipment adopts a symmetrical meshing structure of single screw and double star wheel. As an active part, the screw drives the star wheel to move along the track through rotation to form a continuous closed working cavity. As the screw rotates, the volume of the working chamber gradually decreases, completing the air compression process.
oil-free lubrication system
water is used as lubrication, cooling and sealing medium to replace traditional lubricating oil. The water circulation system forms a water film on the surface of the screw, star wheel and bearing by precisely controlling the water flow and pressure to achieve the following functions:
gas purification mechanism
during the compression process, the air is completely isolated from the water medium to avoid oil pollution. The exhaust end is equipped with a high-efficiency gas-water separator to ensure that the water content of the compressed air is less than 0.001 g/m & sup3 through centrifugal separation and filter element filtration, which meets the oil-free standard.
air purity guarantee
the oil-free design makes the compressed air have zero oil content, which meets the needs of industries with strict air quality requirements such as food processing and pharmaceutical manufacturing. For example, in the production of pharmaceuticals, contamination of the active ingredient with oil can be avoided.
Energy Efficiency and Stability
Maintenance convenience
at present, oil-free screw air compressors are developing in the following directions:
Oil-free screw air compressor with its oil-free, efficient and stable technical characteristics, has become an ideal choice for compressed air supply in modern industry. Enterprises in the selection, should be combined with gas quality requirements, energy efficiency objectives and maintenance costs, after a comprehensive assessment to make a decision.
Parallel operation of two air compressors can significantly improve the flexibility and reliability of the air supply system, especially for scenarios where gas consumption fluctuates greatly or redundant backup is required. The following are the key steps, technical points and precautions for parallel operation: 1. the core objectives of parallel operation.
The frequency of air compressor filter element replacement depends on a number of factors, including the environment in which the compressor is used, the workload, the type of filter element, and the manufacturer's recommendations. The main function of the filter element is to filter the dust, impurities and moisture in the air entering the air compressor to protect
The main differences between oil-free air compressors and oil injectors are reflected in the lubrication method, the use environment and the application field. The following is the specific analysis: Lubrication method: oil-free air compressor: through the use of high molecular weight polymers or other oil-free lubrication
The air compressor is not required to be equipped with a cold dryer. Whether it is equipped or not shall be comprehensively judged according to the requirements of the air-using equipment on the quality of compressed air, the amount of air used and the environmental conditions. The following is a detailed analysis of whether the air compressor needs to be equipped with a cold dryer: The role of the cold dryer The cold dryer is
Answer: In the semiconductor industry, the working pressure of compressed air is usually determined according to specific process requirements and equipment requirements, and the general working pressure range is between 6 and 8kg/cm2. But the specific pressure
There are a lot of equipment in the hospital is driven by compressed air. For example, the high-speed small drill used in dentistry relies on compressed air to turn it up to show the patient's teeth. There is also an atomizer, which is the kind of device that turns the liquid medicine into a tiny mist for the patient to inhale. It also works by compressed air.
Screw air compressors are usually designed to run under load for a long time, but this depends on the specific equipment specifications, manufacturing process and operating environment. The ability of long-term load operation is one of the important indicators of air compressor reliability and durability. Shanghai Gran
The main difference between oil-free compressors and ordinary air compressors is their working method and lubrication system. The following is the specific difference between the two: lubrication method: oil-free compressor: this type of compressor is designed to avoid the use of oil as a lubricant
Compressed air is widely used in dairy factories, mainly in the following aspects: 1. production line equipment drives filling machines, packaging machines, mixers, mixers, etc.: in the production process of dairy products, filling machines, packaging machines, Mixers, mixers, etc.
Analysis of cooling mode of screw air compressor: the selection of air cooling and water cooling is based on the cooling mode of screw air compressor, and the operating environment, energy efficiency requirements and maintenance costs of equipment need to be comprehensively considered. The following from the technical principles, applicable scenarios and selection recommendations of the three parties
