Screw air compressor is a single-stage oil-injected twin-screw compressor. It adopts high-efficiency pulley drive to drive the main engine to rotate for air compression. The compressed air in the main engine is cooled by oil injection. The air and oil mixed gas discharged from the main engine are separated by coarse and fine channels to separate the oil in the compressed air, and finally clean compressed air is obtained. The cooler is used to cool the compressed air and oil.
Screw compressor is one of the positive displacement compressors. The compression of air is achieved by the volume change of the cogging grooves of the male and female rotors that are parallel to each other in the casing. The rotor pair rotates in the casing that is precisely matched with it, so that the gas between the rotor slots continuously produces periodic volume changes and pushes from the suction side to the discharge side along the rotor axis, completing the suction, compression, and exhaust Three working processes.
The structure and working process of 1. screw compressor:
1. Basic structure:
this series of screw compressor unit is mainly composed of compressor, motor, transmission mechanism, cooling system, control system and cover. The compressor is driven by the motor through the pulley of the male rotor, because the male rotor and the female rotor mesh with each other, the male rotor directly drives the female rotor to rotate together. The ratio of the number of teeth of the male and female rotors is 5:6. Both ends of each rotor shaft is equipped with high-precision bearings, so as to ensure that the rotor and the casing, male and female rotor has a small gap between, so the compressor can always maintain high efficiency and long-term operation reliability, fully shows the characteristics of high operating rate of screw compressor.
2. Screw compressor working process:
after the atmosphere filters out dust or impurities through the intake filter, it enters the suction cogging volume cavity of the compressor through the intake control valve. With the meshing movement of the male and female rotors, the air in the cogging volume cavity is gradually compressed. When the air is compressed to a specified pressure, the compressed air is discharged from a specific exhaust port, and then flows through the oil and gas separation tank. At this time, the compressed and discharged oil-containing gas passes through collision, interception, the vast majority of the oil medium is separated, and then enters the oil and gas separation core for secondary separation to obtain compressed air with little oil content, and finally cooled by the air cooler for the user to use. The compressor host carries out 5 working cycles per revolution, so the working pressure fluctuation of compressed air is small and the pressure is stable. Therefore, if the working place is limited by conditions, it can be directly connected without air storage tank.
Oil-free air compressor theoretically no clearance volume, single capacity, ideal isothermal compression, due to the good thermal conductivity of water, lubricating water into the compression chamber, the temperature will drop to 45 ℃, close to the suction temperature. Oil-free: water to replace oil, lubrication, cooling, sealing, noise reduction of the four effects, to provide 100 oil-free air, no pollution, the discharge of water without special treatment, in line with environmental requirements.
View detailsgranklin air compressor is focused on water lubrication screw air compressor research and development and manufacturing of the brand. We are committed to providing clean and efficient compressed air solutions for various industries through innovative technologies to meet the needs of demanding air quality applications.
Screw air compressor factory direct good? Factory direct sales of products is good, this problem we all know good. Air compressor is a need for after-sales products, not only to buy the air compressor can be long-term stable operation, the need for a complete set of after-sales system, parts supply system.
There are many types of air compressors, and they are generally subconsciously divided into oil-free screw air compressors and oil-free air compressors. This two in addition to the lubricating oil method is not the same as what is not the same? Mentioned oil-free air compressor many people's first reaction is not oil,
Oil-free air compressor three filters mainly include: oil-free air filter, oil-free oil filter, oil-free oil and gas separator. The method of replacing each filter element is slightly different, and we will talk about it separately. The water-lubricated air compressor produced by Shanghai Granklin Group is 100% oil-free.
In recent decades, the research on oil-free screw compressors has become increasingly active, and many countries and enterprises have begun to explore the road of oil-free screw compressors on the basis of the original oil-injected screw compressor models. In areas with high gas quality requirements, such as textiles, metallurgy
An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are of the reciprocating piston type. As an important form of energy generation, air compressor is widely used in all aspects of life and production. In particular, single-screw air compressors are widely used in machinery, metallurgy, electronic power, medicine, packaging, chemical, food, mining, textile, transportation and many other industrial fields, becoming the mainstream product of compressed air.
View detailsAir compressor is the main equipment in industrial production. The production of all walks of life is inseparable from air compressor. With the development of science and technology, many industries have put forward higher requirements for air compressor. They require the air compressed by air compressor to be cleaner. In order to achieve this effect, we need to use more functional air compressor equipment, which is oil-free screw air compressor. So how much do you know about oil-free screw air compressor?
Need to purchase air compressor, need to take into account the cost of what? This problem is to understand many aspects, and is a very professional problem, can not unilaterally say a price. Just like you buy a car, different brands have different models
Can the compressed air of the water-lubricated air compressor be used directly without treatment? The exact answer is no. The air compressed by the air compressor is cooled by the rear cooler. After the air-water separator is separated and the buffer tank is stabilized, it is generally in a saturated state. Its relative humidity is 100, and there will be impurities such as solid particles. This compressed air cannot be used directly and needs to be dried and purified.
