Speed coupler hydraulic mechanical coupler hydraulic coupler manufacturer postage Characteristics of variable speed hydraulic coupling 1) The variable speed hydraulic coupling can realize the no-load or light-load start of the power machine (motor), reduce the starting current and torque of the motor, and shorten the starting time of the power machine. 2) Slow down the mechanical impact and damage of the power machine to realize the smooth start. 3) The electrical system, power machine and working machine are effectively protected. 4) Reduce equipment failure rate and prolong equipment service life. 5) The variable speed hydraulic coupling is easy to realize electric and automatic remote control. 6) Reasonable matching and reduced installed capacity. 7) Speed-adjustable hydraulic coupling can realize stepless speed regulation. Under the condition of constant input speed, the output speed can be changed by adjusting the liquid filling amount of the coupling working chamber. 8) The output speed can be automatically adjusted according to different working conditions, so as to realize the energy-saving effect. When it is used in fluid machinery (such as fans and pumps) requiring speed regulation, it has a remarkable energy-saving effect, with the energy-saving rate reaching 20% ~ 40%. 9) Speed-adjustable hydraulic coupling has simple structure, simple operation and maintenance, low maintenance cost, reliability, no mechanical wear and can work in harsh environment. Application field of variable speed hydraulic coupling Speed-adjustable hydraulic coupling is mainly used in different working conditions, which often need to change the running load of power machine, but the running load can be changed by stepless speed regulation. Such as: all kinds of fans, pumps, conveyors, mixers, rollers, compressors, hoists, crushers, granulators, aerators, etc. in electric power, iron and steel, nonferrous metallurgy, cement, mining, chemical industry, textile and paper making, petroleum and petrochemical, coal, transportation, municipal water supply and gas supply, military equipment and other industries
