履带式推土机在大负荷和高温环境工作,其散热必须充分。为了评价履带式推土机散热性能,必须进行热平衡试验。本文介绍履带式推土机热平衡试验方法。1.试验准备(1)准备测温元件热平衡试验前需准备测温元件,该试验所用的测温元件分为无压型热电偶温度传感器和压力型热电偶温度传感器。无压型热电偶温度传感器只能用于测试温度,并可将信号输出,如图1a所示。压力型热电偶温度传感器,可以同时测试温度和压力,并可将信号输出,如图
Crawler bulldozer working in heavy load and high temperature environment, the heat must be sufficient. In order to evaluate the thermal performance of crawler tractors, a thermal equilibrium test must be carried out. This article describes the track-type bulldozer thermal equilibrium test method. 1. Test Preparation (1) Preparation of temperature measurement device Before the heat balance test to be prepared temperature measurement components, the test temperature components used are divided into non-pressure thermocouple temperature sensor and pressure thermocouple temperature sensor. Pressureless thermocouple temperature sensor can only be used to test the temperature, and the signal can be output, as shown in Figure 1a. Pressure thermocouple temperature sensor, you can simultaneously test temperature and pressure, and the signal output, as shown
