 液粘离合器
 “YL-8型液体粘性调速离合器”是*******公司最新开发、研制成功的高效节能产品。2004年7月24日，通过辽宁省科技成果鉴定，成果达到国际先进水平。
 YL－系液体粘性调速离合器之名称代号；
 8－系设备之公称扭矩代号，单位是“千牛·米”。YL-8，即表示该设备可以传递8000N·m的扭矩。
 它是依据牛顿液体内摩擦定律，即液体的粘性和油膜的剪切作用发展而成的一种新型流体传动装置。
 其主要特点如下：
◆可以实现主电机与负载之间的分离、接合和无级调速。
◆可以通过自动控制系统对转速实现闭环控制，可以进行手动、自动或远距离控制。
◆具有广泛的用途，在矿山、冶金、石油、化工、水厂等领域，用于大功率风机和水泵的调速节电、以及大惯量负载的平稳启动和防止启动、制动过程中传动系统的过载，并对传动系统各部件进行过载保护。
◆机械式，构思新颖、结构简单、运行可靠、维修简便、操作容易、节能效果显著、价格便宜。

Clutch fluid viscosity
 YL-8 hydroviscous drive (HVD) is an energy-conservation product with high efficiency newly developed by Petroleum *****High-Tech Co., Ltd . It has passed technical appraisal organized by Liaoning Province on July 24, 2004, and the achievement of which has reached world advanced stage.
 YL－symbol of HVD;
 8－symbol of nominal torque, the unit of which is kN·m. YL－8 shows that the equipment can transmit torque of 8000 N·m.
 HVD is a new fluid drive equipment, the principle of which is the viscosity of fluid and the shearing effect of oil film, as expressed by Newton’s internal-friction law.
Characteristics:
The main AC motor can be separated from or connected with working machine, and the speed can be regulated steplessly.
 Closed loop control of rotation speed can be realized manually, automatically or long-distance by automatic controlling system. 
 ◆  It is widely used in mining, metallurgy, petroleum, chemistry and water supply fields, for large power fans and pumps to save energy, for loaded machines with large inertia to start smoothly, and to protect transmitting system from over-loading in starting or braking stage, and for all parts in transmitting system to be protected when over-loaded.
 ◆It is a new mechanical product with simple structure, high running reliability, maintainability and operability, apparent energy-conservation effect, and low price.
