YOTJ560-1000 Valve-Regulated Variable Speed Hydraulic Coupling

The YOTJ560-1000 valve-regulated variable speed hydraulic coupling is a newly developed hydraulic transmission product on the basis of the working conditions of the adjustable speed drive of induced draft fan for boiler and special environment requirements in the industry. It is primarily applied to driving a variety of centrifugal fluid conveying equipment such as draft fans, blowers and pumps in the petroleum, power and other energy industries.

The valve-regulated variable speed hydraulic coupling uses unique active nozzle inlet valve-regulated speed adjusting technology which has been proven by Jinan Diesel Engine Company over the past decade. Compared to extension tube outlet regulating technology, the speed regulation mechanism of our variable speed hydraulic coupling has simple structure, and high reliability which especially meets the long-time, continuous operation requirement in the petrochemical industry.

Advantages
1. With automatic closed-loop control, the variable speed hydraulic coupling reducer saves energy by 5%~10% on average under normal working conditions and up to 20% under variable speed operation conditions.
2. The valve-regulated variable speed hydraulic coupling can meet the requirement of three-year, continuous, trouble-free operation in the petrochemical industry.
