Hydraulic coupling is a non-rigid coupling using liquid as the working medium, also known as hydraulic coupling. Hydraulic coupling is a power transmission device commonly used in coal mines. It is used to connect the motor and the reducer. It can effectively improve the starting performance of the motor and play the role of overload protection.
Hydraulic couplers for scrapers are mainly used to transmit power. They can achieve stepless speed regulation during the transmission process, reduce the impact load when the power source starts, and can also protect the power source when the transmission components are overloaded.
Functions of the coupling: smooth starting, reducing impact and vibration during operation. , Improve the motor capacity and reduce the inrush current of the power grid.
Scraper coupler, mining coupler, torque-limiting hydraulic coupler, speed-regulating hydraulic coupling
Fluid coupling, limited-moment and speed-regulating hydraulic coupling, with oil medium And water medium coupling, the transmission power of water medium hydraulic coupling is . . times that of oil medium.

If the user does not have strict requirements, the coupling can be rotated When the oil filling plug is rotated to the highest point of the vertical centerline, when the working fluid in the chamber just flows out, it can be regarded as the optimal oil level for the coupling to transmit higher rated power. It is recommended that users adjust the amount of oil filling according to the actual workload and working conditions.
Structural performance characteristics and selection considerations:
External wheel drive, the impeller in the cavity is used as the turbine, the impeller connected to the outer shell is used as the pump impeller, the elastic coupling is on the motor side, and the weight of the coupling is mainly Beared by the reducer shaft.
There is a rear auxiliary chamber, which is a dynamic pressure leakage type. It has strong instantaneous overload protection capability, fast response speed, low overload coefficient, and can effectively limit the starting torque.
Series II is a dedicated supporting product for type II belt conveyor
The correct oil level is very important for the normal operation of the coupling. It is recommended to check the oil level regularly. It is recommended to purchase a torque-limiting hydraulic coupling sight glass. Through the sight glass, you can easily check the liquid filling amount at any time without opening the coupling
Couplings generally use oil media. Recommended working fluids: hydraulic oil, hydraulic transmission oil, refrigeration oil, motor oil, and mechanical oil. Coal mine underground application
The coupling uses clean water and flame-retardant liquid as the medium.
