FG sliding-vane air compressor

Sliding-vane air compressor is a novel development type of oil-jet rotary compressor, which is characterized by high-efficiency, economical and reliable comprehensive application performances. It is especially known by operation stability and low noise. Thanks to its pretty appearance, compact structure and reasonable design, it looks more concise and beautiful than any type of compressor. No oil or air control pipelines can be seen at the main frame. Its new modular insertion technology and compact exterior embodies the high technology in compressor manufacture.

Its basic principle of operation: After entering the air filter, the air is sucked in by the inlet load-dropping valve, which is mainly used for regulation of the pressure cavity generated by the cylinder, rotor and sliding vanes. The rotor rotates eccentrically relative to the cylinder. The sliding vanes are mounted in the rotor groove, and are pushed to the cylinder wall by the centrifugal force. The high-efficiency oil jet system can ensure the cooling and lubrication of the compressor, and can form a thin oil film on the cylinder wall to avoid direct metal-to-metal contact resulting in abrasion. During the compression, the volume between the sliding vanes of the rotor and the cylinder of the compressor decreases increasingly, and pressure is generated. The compressed oil-gas mixture is subject to the coarse and fine separators, making the oil content in the compressed air less than 3PPM. The purified air enters the radiator for cooling, and then enters the working pipeline at only 2~4oC above the ambient temperature.

Besides the applications of the normal piston-type and screw-type compressors, FG sliding-vane air compressor is especially suitable for the places and equipment that have strict requirements for vibration, noise and compressed air quality, and, due to its excellent quality and performances, is widely used in the industries such as harbor machinery, rail traffic, medicine, food, light textile, instrumentation, electronics, petrochemical, water treatment, electricity and road machinery.

HP rail vehicle air supply system
Rail vehicle air supply system is mainly used for the braking, pneumatic springs, open/close of doors, elevation of collection bows, etc.
Rail vehicle air supply system is composed of the air compressor, motor, electrical control box and air post-treatment equipment, in which the air compressor is the main part. Currently, the air compressor for the rail vehicle air supply system is mainly of piston type. The screw-type applications are quite few and are in trial. However, both the two types of air compressors, imported or domestic, have disadvantages such as high noise, high vibration and high maintenance cost. Especially the domestic piston-type or screw-type air compressors, due to their even higher failure rate, are generally excluded from the localization process of the rail vehicles. The imported air supply systems, although with relatively reliable performances, are expensive and have high vibration and noise, directly affecting the surroundings along the stations and rails as well as the comfort. Once the warranty period is due, the maintenance cost is also unbearable. Therefore, all the domestic rail vehicle manufactures and operators are paying high attention and looking forward to the existence of domestic air supply systems with higher cost effectiveness.
To play a role in the localization process of the rail vehicles, our company has been engaged in the research and development of the rail vehicle air supply system since 2003. The main idea is to assemble a novel rail vehicle air supply system with the sliding-vane air compressor made by our company as the main part and with the macromolecular film dryer as the post treatment device for the compressed air.
As the sliding-vane air compressor is a new type of rotary air compressor, it has the features such as compact structure, beautiful appearance, operation stability with no vibration, low failure rate, maintenance-free metal parts and much lower maintenance cost compared with other types of air compressors. The macromolecular film dryer technology is a new technology appearing in 1980s in the foreign countries, characterized by high drying efficiency, low volume, no need of mechanical and electrical control, long service life and reliable performances. It is with such two advanced technologies and parts that our designed and developed the novel rail vehicle air supply system.
Currently, the rail vehicle air supply system developed by our company is completely comparable with the foreign rail vehicle air supply systems in the technical performance requirements such as operation reliability of air compressor, noise, vibration, volume, automation control level, compressed air cleanliness and suspension of air supply single system. The completion of this project means the technology has achieved the acme of the rail vehicle air supply system technology domain.

HPY sliding-vane boosting oxygen enhancer (oxygen dragon)
By right of the fully oil-free sliding-vane compressor technology and the high-tech means owned and combining the application of new materials, the company successfully developed HPY sliding-vane boosting oxygen enhancer (oxygen dragon). It can transfer the oxygen in the air rapidly to the aquiculture waters, resolving the problem of oxygen deficit in the waters caused by water quality deterioration and high-density aquiculture. (This is not only a problem for the aquiculture trade of our country but also a big problem for the international aquiculture trade.) It has been subjected to the trail application in the “South America white prawn intensive high-density” aquiculture base, and the various parameters all have achieved the highest level (which no similar equipment in foreign countries can achieve). A patent is applied for it, with the Patent Application No. of 200520039115.8.
To advocate the industrialized, intensive and high-density aquiculture, a problem to be resolved urgently is the water bottom oxygen aeration. Up to today, there is not an economical and effective method for it, and it has become a factor that restricts the development of high-density aquiculture. HPY sliding-vane boosting oxygen enhancer (oxygen dragon) will be an ideal option.
HPY sliding-vane boosting oxygen enhancer (oxygen dragon) is a novel oxygen enhancing device combining low-pressure oil-free sliding-vane compressor technology and macromolecular micropore oxygen aeration tube. During the operation, clean low-pressure air escapes from the micropores of the oxygen aeration tubes laid at the water bottom, generating a great deal of mini-sized air bubbles with large tension and diameter of 10-15mf, which permeate in the waters in foggy form. Because the mini-sized air bubbles generated have quite high tension, “bubble incorporation” phenomenon are note easy to occur like other aeration oxygen enhancers. These air bubbles can stay for longer time in the waters, so the oxygen in the air can be dissolved in water more sufficiently and more rapidly. In the meantime, the toxic gases such as sulfureted hydrogen and sulfureted ammonium generated due to the decay of aquatic dejection and remnant feedstuff will escape from the water along with the elevated air bubbles, maintaining fine water environment and ensuring the healthy growth of aquatile. The aeration and oxygen enhancing problem for the high-density, industrialized and intensive aquiculture is resolved completely.
