The single screw compressor consists of a cylindrical screw and two symmetrically arranged planar star wheels, which are installed in the casing. The screw groove, the inner wall of the casing (cylinder) and the star gear teeth form a closed volume.
The power is transmitted to the screw shaft, and the screw drives the star wheel to rotate. The gas enters the spiral groove from the suction cavity, and is discharged through the exhaust hole and the exhaust cavity after being compressed. The role of the star wheel is equivalent to the piston of a reciprocating piston compressor. When the star wheel teeth move relatively in the groove, the enclosed volume gradually decreases and the gas is compressed.
The screw of a single screw compressor has 6 screw grooves, the star wheel has 11 teeth, which is equivalent to 6 cylinders, and the two star wheels mesh with the screw grooves at the same time. Therefore, one revolution of the screw is equivalent to 12 cylinders doing work.
As we all know, screw compressors (including twin screw and single screw two) in the rotary compression sweep L the largest proportion.
From the perspective of the international market, during the 20 years from 1963 to 1983, the annual growth rate of screw compressor sales in the world was 30%. At present, Japan, Europe and the United States and other countries in the medium volume of the compressor, the twin screw compressor accounted for 80%.
As a single screw compressor and twin screw compressor in the same range, in comparison, twin screw with its good processing technology, high feasibility, in the whole screw machine market accounted for more than 80% of the share, single screw compressor accounted for less than 20%. The following is a brief comparison of the two compressors.
structure
the screw and star wheel of a single screw compressor belong to a pair of spherical worm pairs, and the screw shaft and star wheel shaft must be kept vertically in space. The female and male rotors of a twin screw compressor are equivalent to a pair of gear pairs, and the female and male rotor shafts are kept in parallel positions.
Driving mode
both compressors can be directly connected to the motor or driven by a pulley, but when the twin-screw compressor rotates at a higher speed, it is necessary to increase the speed of the gear.
Single screw is currently suitable for water-lubricated oil-free mode. The sales volume of single screw water-lubricated oil-free air compressor produced by Shanghai Granklin Group is increasing year by year.
Permanent magnet air compressor is a kind of equipment that uses permanent magnet synchronous motor to drive compressor to compress air. Its main features and uses can be summarized as follows: Working principle The working principle of a permanent magnet air compressor is to convert the electrical energy output by the permanent magnet motor into mechanical energy, thereby driving the pressure
Air compressor machine can do explosion-proof treatment. The explosion-proof of the air compressor refers to the comprehensive explosion-proof measures including the explosion-proof of the motor and other parts of the unit. The specific requirements are as follows: every part of the unit, including motors, pipes, containers, etc., must meet
In the chip factory, compressed air has a variety of applications, including but not limited to the following: Cleaning and drying: Compressed air is used to clean the surface of the chip and the inside of the device to remove dust, particles and other contaminants. Due to the moisture and impurities in the compressed air
Oil-free air compressors are designed to operate for long periods of time to meet the continuous compressed air demand in industrial applications. Compared with the traditional oil air compressor, oil-free air compressor provides pure compressed air, but also has the ability to run continuously. Shanghai
The maintenance cycle of an air compressor depends on a number of factors, including the type of equipment, the environment in which it is used, the length of operation, and the manufacturer's recommendations. Generally speaking, air compressors need regular maintenance to ensure their normal operation and extend their service life. For Hagrid
There may be many reasons for the large vibration of the screw compressor, including the following common situations: the anchor bolts of the unit are loose or the rigidity of the frame is poor. Poor alignment between compressor and prime mover. Unbalanced compressor rotor or worn bearing.
The moisture content in the air is not fixed, it is affected by temperature, humidity, geographical location and other factors. Generally speaking, people talk about the amount of moisture in the air is usually expressed in terms of relative humidity, rather than a specific ppm (parts per million) value. Phase
When looking for an efficient and environmentally friendly oil-free screw air compressor, Shanghai Grankering Group is undoubtedly a choice worth considering. The group focuses on the research and development, design, production and sales of oil-free screw compressors. It has independent intellectual property rights and is a national high-tech enterprise
The energy consumption of oil-injected air compressor and oil-free air compressor is compared as follows: Oil-injected air compressor: During the working process of the oil-injected air compressor, the compressor needs to be lubricated and cooled through the oil injection system, so it will consume a certain amount of Lubricating oil. At the same time, due to the lubrication of the oil-injected compressor.
In the plastic products industry, medium and high pressure air compressor plays a pivotal role. Its key role is like a careful and highly skilled craftsman, ensuring that every link is accurate and accurate, providing a solid guarantee for product quality and production efficiency.
