在对液压元件进行静态试验和模拟主机工况进行系统试验时,需要对工作介质的温度进行测量和控制。在以往的试验中,我们通常使用电接点压力式温度计(例如WTZ—288型温度计)来测量和控制油箱或低压回路油的温度。使用压力式温度计可以很方便地实现20米以內距离的温度测量和控制,但是这种温度计温包体积较大(一般为φ22×300),安装于低压回路上需要专门设计。为了克服压力式温度计在测量低压回路油温的不足之处,我们对测量部分进行了改进,其方法如下:用超
In the hydraulic components of the static test and simulate the host operating conditions for system testing, the need for the working medium temperature measurement and control. In previous experiments, we typically used electrical contact pressure thermometers (such as the Model WTZ-288 thermometer) to measure and control the temperature of the fuel tank or low pressure circuit oil. The use of pressure thermometer can easily achieve the distance measurement within 20 meters and control, but this thermometer temperature package volume (usually φ22 × 300), installed in the low pressure circuit needs to be designed. In order to overcome the inadequacies of the pressure thermometer in measuring the temperature of the low-pressure circuit oil, we have improved the measurement part, the method is as follows:
