The YDB670-900 hydraulic torque converter with adjustable guide blades is a new type hydraulic transmission product designed in view of the characteristics of the working conditions for constant pressure speed-adjustable drive of high pressure plunger pumps in the petroleum and petrochemical industry. It is widely used in the fields of petrochemical and drilling rigs and primarily used for driving a variety of reciprocating compressors and pumps.

The hydraulic torque converter uses adjustable guide blades as the control elements for speed regulation. The torque converter has a wide speed regulating range and superior performance to speed-adjustable hydraulic coupling and non-adjustable hydraulic torque converter.

Advantages
1. The hydraulic torque converter with adjustable guide blades provides intelligent, multi-revolving electric actuator, and automatic closed-loop control.
2. It extends the lifetime of the electric motor and the working machine. The electric motor can offer no-load, smooth starting.
3. The torque converter meets the special requirement in the petrochemical industry by providing three years of continuous, trouble-free operation.
