Principle of screw air compressor
1. Inspiratory process:
the screw-type air intake port must be designed so that the compression chamber can fully inhale, while the screw compressor does not have an air intake and exhaust valve group. The air intake is only adjusted by the opening and closing of a regulating valve. When the rotor rotates, the tooth groove space of the main and auxiliary rotors will be the largest when it is turned to the opening of the intake end wall. At this time, the tooth groove space of the rotor communicates with the free air in the air inlet, because all the air in the tooth groove is discharged during exhaust, when the exhaust is over, the tooth groove is in a vacuum state. When it turns to the air inlet, the outside air is sucked in and flows into the tooth groove of the main and auxiliary rotors along the axial direction. When the air fills the entire tooth groove, the end surface of the air inlet side of the rotor turns away from the air inlet of the casing, and the air between the tooth grooves is closed.
2. Closure and conveying process:
at the end of the suction of the main and auxiliary rotors, the teeth of the main and auxiliary rotors are sealed with the casing. At this time, the air is closed in the tooth groove and no longer flows out, that is, [closing process]. The two rotors continue to rotate, their tooth peaks and tooth grooves coincide at the suction end, and the anastomosis surface gradually moves to the exhaust end.
3. Compression and fuel injection process:
in the conveying process, the meshing surface gradually moves to the exhaust end, that is, the tooth groove between the meshing surface and the exhaust port gradually decreases, the gas in the tooth groove is gradually compressed, and the pressure increases, which is the [compression process]. At the same time, the lubricating oil is injected into the compression chamber and mixed with the chamber gas due to the pressure difference.
4. Exhaust process:
when the meshing end surface of the rotor turns to be connected with the casing exhaust, (the pressure of the compressed gas is the highest at this time) the compressed gas starts to be discharged until the meshing surface of the tooth peak and the tooth groove moves to the exhaust end surface. At this time, the tooth groove space between the meshing surface of the two rotors and the casing exhaust port is zero, I .e. the exhaust process is completed. At this time, the tooth groove length between the meshing surface and the casing inlet of the rotor is the maximum, its inspiratory process is underway again
Shanghai granklin group is engaged in the production and processing of oil-free and water-lubricated air compressors. we are focused on the production of screw air compressors. doing a good job in water-lubricated air compressors can make mechanical failures lower and users feel more at ease in using gas. On the use of the effect to see the screw air compressor has the following advantages.
Energy conservation and environmental protection is always advocated by our country, and the R & D teams of manufacturing enterprises are also trying to develop energy-saving equipment. The screw air compressor, as one of the important gas equipment for production enterprises, will inevitably cause environmental pollution in the process of use.
Air compressors are generally classified into the following categories: 1. According to the gas transmission volume, to put it bluntly, the gas transmission volume refers to the volume of the gas discharged from each minute of the air compressor during operation, calculated to be sucked in. The small and medium-sized exhaust volume is less than 10 cubic meters/minute, and the small and medium-sized exhaust volume is 10~100 cubic meters
How to distinguish oil-free air compressor is good or bad, reduce cost, energy saving and environmental protection, work efficiency and noise pollution is still very low. In the choice of permanent magnet variable frequency air compressor to choose a good oil free air compressor.
View detailsThere are so many domestic air compressor manufacturers, and the number is large. Before purchasing, it is best to look at the factory scale, production capacity, and various certifications and user cases of the product, and evaluate whether the air compressor manufacturer can meet its own needs.
View detailsOne of the two major faults that often occur during the use of screw air compressors is oil leakage. Oil leakage faults are divided into many kinds of organic head oil leakage and shaft seal oil leakage. The rotor of a carbon dioxide screw press in an enterprise is divided into two parts: yin and yang, with a rotating speed of 2157r/min.
Before using the air compressor, please read the manual or discuss with the air compressor technician, the equipment is safe and the cost of the enterprise is reduced. Before operating the air compressor, you must be familiar with the following issues: 1. Keep the lubricating oil in the oil pool within the scale range, and the flow rate of the tanker before the air compressor runs shall not be lower than the scale line value.
It is obvious to all that the oil-free water lubrication air compressor is excellent. As a category of air compressor, the sales volume is increasing year by year. Users who do not understand its advantages can read this article. 1. The compressed gas of the non-oil-water lubricated air compressor is 100% oil-free, the whole structure of the air compressor is more reasonable, and the cost of maintenance consumables is less;
