今天所应用的液压油的粘度同温度有很大关系。实验工作要求有一种装置,使温度及粘度保持精确、恆定。下面介绍这种温度调节装置的主要特性和构造设想。一、装置的功能和结构要使液压油液进口温度恆定,基本上有三种方法: 1.冷却或加热油箱中的液体; 2.液体注入试验台时冷却加热之; 3.热油油箱中的液体同冷油油箱中的液体混合。系统1惰性较大,对理论值的改变和由于
The viscosity of the hydraulic fluid used today is strongly related to temperature. Experimental work requires a device that keeps the temperature and viscosity accurate and constant. The following describes the main features of this temperature control device and the construction idea. First, the function and structure of the device To make the hydraulic fluid inlet temperature is constant, there are basically three ways: 1. Cooling or heating the liquid in the tank; 2. The liquid is injected into the test bed cooling and heating; 3. Hot oil tank The liquid is mixed with the liquid in the cold oil tank. System 1 is more inert, due to changes in theoretical values
