稳定淬火介质的温度,对提高淬火质量有十分重要的作用。为此我们结合生产实际,设计了图1所示的淬火介质温度控制装置。控温原理将接点压力式温度计的温包插入淬火介质槽内,测试出槽中介质的温度,然后通过表中上下限温度控制触点,发出信号控制电磁阀门的开合来实现 Stable quenching medium temperature, to improve the quality of quenching has a very important role. To this end, we combine the actual production, design of the quenching medium temperature control device shown in Figure 1. Temperature control principle Contact pressure thermometer temperature package inserted into the quenching medium tank, test the medium temperature in the tank, and then through the table on the lower limit temperature control contacts, send signals to control the solenoid valve opening and closing to achieve
