四、塑料低温脆性试验机结构原理

 

Four, low temperature brittle plastic testing machine structure principle

 

1、本设备由制冷压缩机主机体、加热装置、电子控制箱、冷却槽、冷却介质循环系统、自动报警装置等部分组成。启动制冷开关后,压缩机开始工作,制冷系统进入正式工作状态。制冷压缩机连续不断的工作,当接近设定温度时,冷却槽中的加热装置开始按比例提供热量,用以平衡制冷系统产生的多余冷量,以达到恒温的目的。搅拌可使冷却槽内的冷却介质不断循环,使温度均匀*。

 

1, the equipment is composed of a refrigerating compressor main body, a heating device, an electronic control box, cooling tank, a cooling medium circulating system, automatic alarm device components. Start the cooling after the switch, the compressor starts to work, the refrigeration system into the official working state. The work of refrigeration compressor continuously, when close to the set temperature, the heating device cooling tank to provide heat is proportional to balance, with excess cold refrigeration system, in order to achieve the purpose of constant temperature. Agitation can make the cooling medium cooling groove continuous cycle, so that the temperature is uniform.
