液力偶合器在工程应用中有许多优点:如自动适应性、便于实现无级调速、无磨损、防振隔振、启动性能优良等,因此,得到广泛地应用。特别是在能源紧张的今天,将调速型液力偶合器,用于耗电量很大的系统,如风机、电站高压锅炉给水泵等,有着极为重要的节能作用。但通过试验及实际应用中发现,调速型液 Hydraulic coupling has many advantages in engineering applications: such as automatic adaptability, easy to achieve stepless speed regulation, no wear, vibration and vibration isolation, starting performance and so on, therefore, has been widely used. Especially in today’s energy-intensive, speed-controlled fluid couplings are used in systems that consume a lot of power, such as fans and high-pressure boiler feed pumps for power stations, which have an extremely important energy-saving effect. However, the test and practical application found that speed control fluid
