General air compressor units refer to screw air compressor units as follows:
The screw air compressor type provides compressed air for related equipment to provide power. General screw air compressor unit consists of air filter, intake valve, air compressor, exhaust check valve, oil and gas barrel, oil fine separator, pressure maintenance valve, rear cooler and protection device, dryer, storage Gas tank and other components.
There are four common components of screw air compressors: air compressor, air storage tank, dryer / dryer, and filter.
1. Air compressor: It is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. It is a pressure generating device for compressed air.
2. Gas storage tank refers to the equipment used to store gas, which also stabilizes the system pressure. It can be divided into high pressure gas storage tank, low pressure gas storage tank and atmospheric pressure storage tank according to the pressure of the gas storage tank. According to the material of the gas storage tank, it can be divided into: carbon steel gas storage tank, low alloy steel gas storage tank, stainless steel gas storage tank. The gas storage tank (pressure vessel) is generally composed of parts and components such as a cylinder, a head, a flange, a pipe, a sealing element and a support. In addition, it is also equipped with safety devices, meters and internal parts that perform different production processes.
3. The main function of the dryer is to remove water from the compressed air and ensure the stability of production. Compressed air needs to pass through the pipeline to reach the pneumatic equipment and air end during production. Compressed air usually contains impurities such as water, oil, and dust. It comes from air. If it is not processed, it will lose pipelines, damage pneumatic equipment, and contact The product leads to a decline in the product process, so compressed air purification equipment is configured to purify the compressed air.
Cold and dry machine is the refrigerated dryer: Use refrigeration technology to reduce temperature and remove water.
The dryer is an adsorption dryer: the characteristics of adsorbing moisture by using an adsorbent (active alumina, silica gel, molecular sieve) all adsorb the material to reduce the moisture content in the compressed air.
4. Filter: an indispensable device on the conveying medium pipeline, which is usually installed at the inlet of other devices such as pressure reducing valves, pressure relief valves, fixed water level valves, and square filters. After the filter has a certain size of the filter cartridge, its impurities are blocked. When cleaning is needed, just remove the removable filter cartridge and clean it. Maintenance is simple and easy.
