Review of liquid viscosity technology and its application

Aiming at the special environment of transport machineries used in coal mines and the request of high reliability of its inertia braking system, the concept, performance and characteristic of liquid viscosity were presented, the design of application of liquid viscosity technology for belt conveyor in coal mines, the structure of liquid viscous brake, the design of hydraulic system and the main expected index of technology were introduced. The matters attentioned about the core structure, the design and calculation, heat dissipation and anti-explosion, use and maintenance of coal mine machine were pointed out. The results indicate that the liquid viscous braking systems have large moment, high reliability, good stability and convenient control, and it would satisfy the braking system＇s need of the powerful belt conveyor.
