Chengdu Hantu Trade Co. Ltd. located at Longquanyi District is registered upon approval of the relevant department. It has offices in Beijing, Tianjing, and Uzbekistan and specializes in export marketing and product and technical consulting service. It is mainly engaged in natural gas compressors and complete equipment, mechanical and electrical products, handworks, construction materials, steel, pipeline valves used in CNG stations,, which are sold as far as Russia, the West, and Southeast Asia. Based on the tenet "Integrity, Pragmatism, Cooperation, and Win-win", we has built up long-term partnership with many well-known companies inland, and our products win a good reputation both inland and abroad.
In order to meet demands of users in CNG stations, various skid-mounted automatic or semi-automatic natural gas boost compressors and supporting devices are provided. With many specialized technical, managerial and sales talents, great technical strength, and marketing experience, our company has built a perfect technical support and marketing system and established its competitive edge in this industry.
Base on application of gas booster compressors in CNG stations, they can be classified for standard stations, primary stations, and substations. Based on structure, they can be classified as type D, type M, type Z, and type W. Apart from their own characteristics, natural gas compressors used in CNG stations have the following advantages:
①Solid skids are adopted. Piston compressor unit vibrates mildly, operates stably and saves energy.
②Advanced connection is adopted. Keyless expanding sleeve connection, which used to be adopted on large-scale compressors, is used for connection of crank axles end and flywheels on compressors. Besides, installation is easy with good centering and connection.
③Hardening treatment is adopted on piston rod surface, whose hardness reaches HRC75-80 and friction coefficient is reduced for 15-20%.
④A water-cooled cooler with floating head tabulations that can achieve large areas and multipaths is employed, which improves operation reliability of the unit.
⑤The air valve technology is special. The air valve, whose spring is made of specified pagoda-shape stainless steel wire, is manufactured with special technology.
⑥Combined packing seal technology is employed. During operation, the sealing demonstrates high reliability and long service life, and it is more effective especially in conditions with little oil lubrication. Therefore, the operating efficiency is highly improved.
⑦As for the controlling mode, German Siemens mode PLC+touch screen+soft starting (or variable frequency starting) is employed.
In the future, all the personnel of our company will adhere to the tenet "Success with good qu
