邢台钢铁厂于1987年6月在3号7000—2—2型,N=1600KW高炉鼓风机上安装了第一台YDTZ—30/55型液力偶合器,一次试车成功,7月正式投入运行。至今,全厂已采用5台液力偶合器,其中YDTZ—36/55型3台,YDTZ—40/60型2台。液力偶合器是一个以液体为介质传递功率的装置。它是由原动相连接的泵轮、与被驱动机械相连接的涡轮以及把涡轮包容起来而与泵轮连接在一起的转动外壳所组成。在密闭的工作腔中充满工作液体(介质)。在 Xingtai Iron & Steel Plant installed the first YDTZ-30/55 hydraulic coupling on No.3 model 7000-2-2 and N = 1600KW blast furnace blower in June, 1987. The successful test was put into operation in July. So far, the whole plant has adopted 5 sets of hydraulic couplings, of which 3 are YDTZ-36/55 and 2 are YDTZ-40/60. A fluid coupling is a device that uses liquid as a medium to transmit power. It consists of a pump impeller connected to the motive phase, a turbine connected to the driven machinery, and a rotary housing for containing the turbine and connected to the pump impeller. The working chamber is filled with working fluid (medium). in
