Optional Accessory

Water medium

The Hydrodynamic couplings can operate normally with water and glycol mixture as medium. 

Water medium is more easy to purchase and meets high environmental requirements.

Hydrodynamic couplings with water medium need to add encapsulated devices such as oil seals or bearing sealing end caps to seal the bearings.

Rolling bearings do not need to be filled with oil, but only need grease to ensure service life.

When the water medium is used, the total length of the product will increase.

Balancing Test

Hydrodynamic couplings will be dynamically balanced. Standard balancing quality is Q6,3 at 1500rpm according to VDI 2060 in two planes. 

***If you need to choose other balanced quality standards, please contact us.

Insert shaft sleeve

The use of the inserted shaft sleeve can meet the requirements of different shaft diameters and shaft lengths. The inserted shaft sleeve can be processed and shipped according to the user's requirements.

Fusible plug

When the liquid temperature exceeds the melting point of the fusible plug, the fusible plug is ejected. In this way, the Hydrodynamic coupling is protected from overheating. Fusible plugs have a variety of temperature options. 

Mechanical thermal switch device

The mechanical thermal switch is set with a lower temperature than the fusible plug to provide secondary protection for Hydrodynamic coupling. When the temperature of the temperature control plug of the mechanical switch is reached, a mechanical signal will be sent from the top of the temperature control plug. After the signal is obtained, the drive system will be cut off.

Electronic thermal switch device

Similar to the mechanical switch, it is a secondary protection for Hydrodynamic coupling from overheating. When the Limit temperature is reached, the sensor will send an electronic signal to the analysis unit and converted into another signal to cut off the drive system.

Protective cover

It is necessary to install a protective cover in order to avoid unintentional contact with the rotating elements of Hydrodynamic couplings. The manufacturing of the protective cover fully considers the cooling of the coupling through air circulation. We can provide standard protective cover or special designs according to customer requirements.

Applications of hydrodynamic coupling with double fluid units：

(1) Automobile

Hydraulic couplings were used in early automotive semi-automatic transmissions and automatic transmissions. The pump wheel of the hydraulic coupler is connected with the flywheel of the engine, and the power is transmitted from the crankshaft of the engine. In some cases, the coupling is strictly a part of the flywheel, in which case the hydrodynamic coupling is also called the hydrodynamic flywheel. The turbine is coupled to the input shaft of the transmission. The liquid circulates between the impeller and the turbine, so that the torque is transmitted from the engine to the transmission to drive the vehicle forward. In this respect, a hydrodynamic coupling acts very much like a mechanical clutch in a manual transmission. Since the hydraulic coupling cannot change the magnitude of the torque, it has been replaced by the torque converter.

(2) Heavy industry

It can be used in metallurgical equipment, mining machinery, power equipment, chemical industry and various construction machinery.
