Description

The hydraulic coupler is located between the scraper conveyor motor and the reducer

The role of a hydraulic coupler

1. It has the function of light load protection for the motor, which can reduce the impact and vibration of the transmission system.

2. In the case of scraper conveyor driven by multiple motors, it can make the load of each motor uniform.

3. If it is properly matched with the characteristics of the motor, the starting torque of the driving device can be adjusted.

Hydraulic coupler is composed of pump wheel, spindle, turbine, shell, fusible plug and other parts. Pump wheel shaft and motor connection, turbine shaft and reducer connection. Pump wheel, turbine on the radial straight blade. Pump wheel, turbine and blade constitute a closed working chamber. Through the working fluid in the working chamber, the transfer of power to do spiral tubular composite motion.

The performance of hydraulic couplers is mainly determined by the cavity type. The number, inclination and structure of working impeller blades also affect the performance of hydraulic coupler. Too many blades will reduce the volume of the working chamber and increase the hydraulic loss. In general, hydraulic couplers use zero inclination Angle, can be positive and negative rotation of the blade. However, the performance of the hydraulic coupler will also change if the inclination of the blade is changed. The torque coefficient of the pump wheel of the rake blade is large. On the contrary, the pump wheel torque coefficient of the rear inclined vane is low. The blades with different length and length can reduce the hydraulic loss during hydraulic diffusion. In addition, some other factors such as the viscosity and temperature of the working fluid also affect the hydraulic coupler.
