The predecessor of the China Chemical Safety Association was the China Chemical Safety and Health Technology Association established in 1993. In March 2006, the preparatory group for the association solicited member units nationwide, with the exception of many well-known enterprises in the traditional chemical industry, China National Petroleum Corporation, China Petroleum & Chemical Corporation, China National Offshore Oil Corporation, China Sinochem Corporation, China National Chemical Corporation, China Shenhua Coal Oil Co., Ltd. and other large companies have become members of the association. At present, there are 126 member companies. According to Wan Shibo, vice president of the association, in order to take advantage of the role played by large petrochemical companies in the production of chemical safety, after obtaining the approval of the relevant units, the chairman unit of the association will be elected by the central direct management of large-scale petrochemical enterprises. At the plenary meeting on the 18th, the participants voted to pass the draft of the "China Chemical Safety Association Constitution" and the "China Chemical Safety Association's four-year work plan outline", and elected the association's director, standing director, deputy chairman and director of the association. long. Wang Tianpu, president of China Petroleum & Chemical Corporation, was elected as the chairman of the first association.
Li Yizhong, director of the State Administration of Work Safety Supervision, explained the significance of upgrading the Chemical Safety and Health Technology Association to the Chemical Safety Association. He said that in recent years, the weakening of safety management in the chemical industry is an indisputable fact. Security accidents not only cause harm to practitioners, but also cause more harm to society and the environment than the accident itself. The Jilin accident last year is an example. Last year, 404 safety accidents occurred in China's chemical companies, causing 501 deaths. Among them, 142 accidents caused by hazardous chemicals caused 229 deaths. The accident caused 76 secondary pollutions. In the case of weakened overall management, industry associations should take responsibility.
He also said that according to studies of sociologists and economists, China’s current development stage is at a high incidence of accidents. It took 70 years for the United Kingdom to spend this period, the United States spent 50 years, and Japan spent 28 years, but we cannot Take so long.
High-efficiency Air Compressor
Screw Air Compressor (working principle) :
Screw compressor is a volumetric gas compression machine with working volume for rotary motion. The compression of gas depends on the change of volume, and the change of volume is achieved by the rotary motion of a pair of rotors in the housing of the compressor. Basic structure: in the body of the compressor, a pair of helical rotors are arranged in parallel to each other. Usually, the rotor with convex teeth outside the section circle is called the Yang rotor or Yang screw. The rotor with concave teeth in the section circle is called Yin rotor or Yin screw, a Yang rotor is connected with the prime mover, driven by the Yang rotor Yin rotor rotor rotation on the last pair of bearings to achieve axial positioning, and bear the axial force in the compressor. Cylindrical roller bearings at both ends of the rotor enable the rotor to achieve radial positioning and withstand radial forces in the compressor. At both ends of the compressor body, a certain shape and size of the orifice are respectively opened. One for inhalation, called the air inlet; The other is used for exhaust, called exhaust port.
Product advantages:
1. Screw Air Compressor works smoothly, has small vibration and low noise compared with piston machine.
2, oil and gas separator: filter material, high efficiency, air oil content rate is less than 2ppm.
3, controller: operation and related data are displayed on the control panel, easy and convenient operation.
4, spraying lubricating oil with sealing, cooling, noise reduction and lubrication.
5, high stability, high efficiency, small vibration, low noise advantages.
6. Good heat dissipation system. Adopting plate-fin structure and material, the cooler has high pressure resistance, high heat dissipation efficiency and good corrosion resistance.
7, Air Filter: heavy duty, multi-stage air filter, large working face.
