Compared to metal materials, plastics offer many advantages in cost, design, processing and performance. The inherent design freedom of plastic molding ensures more efficient gear manufacturing. Internal gears, gear sets, worm gears, etc. can be molded from plastic. Plastic gears have a wider application area than metal gears, so they push gears toward higher loads and greater power transmission.

The equipment was imported from Japan's Ebara Corporation by Daqing Petrochemical Refinery and used to recover the pressure energy of the hydrocracking unit. The differential pressure at the inlet and outlet of the turbine is 11 MPa. 1.2 million tons/year hydrocracking unit is a new device put into production by Daqing Petrochemical Refinery in August 2004. The original design of the hot high-pressure oil product outlet temperature is 230°C, the pressure is 13MPa, and the current domestic petrochemical enterprises generally The pressure energy of this high temperature and high pressure medium cannot be recovered or recovered.
High-temperature and high-pressure hydraulic turbine equipment is first used in China
The latest domestic high temperature and high pressure hydraulic turbine energy-saving equipment introduced by PetroChina Daqing Petrochemical Company's oil refinery was recently put into operation on the company’s 1.2 million tons/year hydrocracking unit, saving 2.49 million kwh per year, saving energy. The electricity fee is RMB 1.42 million, which reduces the energy consumption of the device by 1.51%.
