Screw compressors are widely used in aerodynamics, refrigeration and air conditioning, and gas compression in various process flows. Rotor bearings are key components that directly affect the volumetric efficiency and reliability of screw compressors. Rolling bearings used in screw compressors generally require a bearing with a calculated life of more than 50,000 hours. According to statistics, 50% of all running positive displacement compressors are screw air compressors. Because the screw air compressor requires high precision, long service life and high reliability of the rolling bearing, in the past, the domestic screw air compressor rotor bearing used imported bearings. With the rapid development of the domestic compressor industry, the demand for screw air compressor rotor bearings with high precision, long life and high reliability is increasing. The screw air compressor has a compact design. The weight of a screw air compressor is about 1/7 to 1/13 of the weight of a comparable power piston compressor, and is usually directly connected to the prime mover without a reducer. The higher the speed, the bearing needs to withstand medium and above loads. Through the research and development of the screw air compressor rotor bearing, Huanyu Company has significantly improved the speed and accuracy of the bearing, especially the life level, shortened the gap with similar foreign products, and achieved the goal of localization. Huanyu Bearing Co., Ltd. is only a medium-sized professional bearing manufacturer in our province. Why is it winning? “Continuous investment and continuous innovation.†The person in charge of the company introduced that since its establishment in 1998, the company has been advancing in the face of fierce market competition. The transformation of technology and equipment has already possessed domestic first-class heat treatment, automatic temperature control and new and advanced bearing assembly and cleaning production lines, as well as advanced testing equipment and laboratories. Now it has become a national high-tech enterprise with fixed assets of 140 million yuan and a factory area of ​​over 80,000 square meters. Huanyu Company's "Academician Expert Workstation" is the first in Changshan County. They have long-term cooperation with the academician team. They have invested more than 6 million yuan in research and development, focusing on the raw materials, forging, spheroidizing, heat treatment and cold treatment of precision bearings. Breakthrough research and development. In November 2014, this award-winning product passed the expert review and appraisal of provincial industrial new products, and its quality and technical level reached the domestic leading level. In December 2015, the company has two new products that have passed the review and appraisal of provincial industrial new products, and have been upgraded on the original basis, and its technical level has reached the international advanced level. It is precisely because of years of accumulation that the company has obtained 1 invention patent, 10 utility model patents and 5 provincial new products.

The author learned from the relevant departments that the “screw compressor with high-speed precision tapered roller bearing†developed by Zhejiang Huanyu Bearing Co., Ltd. won the third prize of “China Machinery Industry Technology and Technology Award†and realized the zero award of Changshan County Bearing Industry. breakthrough.
“National tens of thousands of machinery and industrial enterprises have won only 189 third prizes, which is not easy.†The person in charge of the company told us that the “China Machinery Industry Science and Technology Award†was established by the China Machinery Industry Federation and the China Mechanical Engineering Society in 2001. Established together and selected once a year.
“We successfully developed high-precision long-life screw air compressor rotor bearings in 2014, and continued to innovate and developed high-speed precision tapered roller bearings for screw air compressors. The two are coherent in technical achievements. The person in charge of the company told us.
The use of drying ovens is an important step in many production processes. Drying helps remove moisture content from coatings and various substrates while also sterilizing a variety of lab equipment and materials. Reduction and control of moisture levels in solid materials through heated drying is a crucial process in the manufacture of many materials. Drying is used across multiple industries for a wide range of applications. This can include paint drying, drying glass and plastics, ink, adhesives, and removing excess water from filter material, to name a few.
