调速型液力偶合器调节特性存在着严重的非线性。由于这一非线性及整个系统响应的滞后,会导致直接使用液力偶合器的系统工作性能产生极大的波动。如水压、风压等,影响了系统的工作运行。为此要对非线性加以补偿,保证液力偶合器、水泵(或风机)所必须的特性曲线。原苏联首先研制了杠杆凸轮操作机构,在机构中装有能保证调节特性曲线所需形状的型线凸轮。但这种方法不但结构复杂,且容易出现卡死现象。随着微机技术的发展,利用微
There is a serious non-linearity in the adjustment characteristics of the speed governing fluid coupling. Due to this non-linearity and the lag of the entire system response, the system performance of the direct use of the fluid coupling can be greatly fluctuated. Such as water pressure, wind pressure, affecting the work of the system. For this purpose, the non-linearities must be compensated to ensure the necessary characteristic curves of the hydrodynamic couplings, pumps (or fans). The former Soviet Union first developed a lever cam operating mechanism, fitted with a profile cam in the mechanism that ensures the desired shape of the adjusting characteristic curve. However, this method is not only complicated in structure but also prone to jamming. With the development of microcomputer technology, the use of micro
