In October 2018, the company's R & D center was identified as the 14th batch of "One Enterprise, One Technology" R & D center by Shandong Small and Medium Enterprise Bureau. Company proprietary technology profile:
The MVR evaporation system developed by the company has a Roots-type compressor reflux cooling system, a two-stage MVR evaporator, a rotary tube MVR concentration crystallizer, an MVR evaporator, a heat exchanger, and a bipolar MVR evaporation crystallization process and equipment. Grade MVR evaporation process method and equipment, low-temperature steam heating method, hot water waste heat recovery and utilization methods and many other patented technologies are widely used in wastewater concentration treatment, evaporation crystallization, traditional Chinese medicine concentration, organic solvent concentration separation, rectification process and seawater Compared with other domestic MVR evaporation technologies, the energy saving during the production process such as desalination is more than 50% compared with the same period of last year. It has the characteristics of wide application range and obvious energy saving effect. The energy-efficient MVR evaporation system passed the scientific and technological achievements appraisal organized by the Science and Technology Bureau of Zibo City in December 2016.
The Roots vacuum pump produced by the company has special claw rotor profile, multi-leaf roots pump universal profile, new three-leaf roots pump rotor profile, involute three-leaf roots pump rotor, roots vacuum pump sealing device, Luo Vacuum pump performance test system and test method, device and method for maintaining condenser vacuum of thermal power plant, multi-stage roots pump, double-stage sealed roots vacuum pump, mechanical seal roots vacuum pump, bipolar three-leaf air-cooled roller Roots vacuum pump, cycloidal trilobal Roots pump rotor, Roots vacuum pump sealing device and other related patent technologies. Through the development and application of Roots pump key technologies such as rotor profile and sealing structure, the rotor outer radius Rm and pitch circle Under the condition of the same radius R, the volume utilization coefficient of the pump is greatly improved, and the increase range is between 30% and 50%. A large pumping speed can be obtained, which has strong practicality and improves the operation of the Roots vacuum pump and compressor. Performance and operational reliability. Our Roots vacuum pumps and compressors have been widely used in power plants, metallurgy, chemical industry and MVR evaporation systems. The Roots vacuum pump developed by the company passed the scientific and technological achievements appraisal organized by the Science and Technology Bureau of Zibo City in December 2016.
