What Are The Disadvantages Of Hydraulic Coupling?

As an important part of Marine equipment, hydraulic coupling has many advantages, such as transmitting large power and torque; Realize stepless speed regulation; Absorb large vibration and shock; Improve system stability and reliability; Remote control and automatic control, etc., it also has certain disadvantages.

The disadvantages of hydraulic coupling mainly include the following aspects:

Hydraulic oil leakage risk: hydraulic couplers need to use hydraulic oil as the working medium, if the seal is poor or the component is damaged, it may lead to hydraulic oil leakage, which will not only pollute the environment, but also may cause damage to the equipment.

High maintenance costs: Maintenance of hydraulic couplers requires specialized knowledge and tools, and if something goes wrong, it may be necessary to replace seals or repair hydraulic components, which is costly.

Sensitive to temperature: the working performance of the hydraulic coupler is greatly affected by temperature, and too high or too low temperature may lead to changes in the viscosity of the hydraulic oil, affecting the transfer efficiency and stability.

Sensitive to vibration: hydraulic couplers are more sensitive to vibration, and excessive vibration may lead to seal wear or component damage, affecting its service life.

Large weight and volume: compared with other transmission methods, the weight and volume of hydraulic couplers are large, which is not conducive to lightweight and miniaturization.

High control difficulty: The control of hydraulic couplers requires accurate flow and pressure control, which has higher requirements for the control system.
