1 前言众所周知,油泵偶件是精密零件,热处理工艺比较严格,加热温度要均匀,温控要很精确。为了更好地满足这一工艺要求,并做到既解决问题又节省费用,我们对热处理车间使用的油泵偶件回火油槽的电气部分进行了一些改装。改装中采用了晶体管恒温控制器并配以适当的电气控制电路,使温控精度达到±1度。经过三年多的使用证明,这项改进确实具有耗电少、升温快、灵敏度高、操作简便、安全可靠等优点。
1 Preface As we all know, oil pump parts are precision parts, heat treatment process is more stringent, heating temperature to be uniform, temperature control is very accurate. In order to better meet the requirements of this process, and to solve both problems and cost savings, we modified some of the electrical parts of the fuel tank tempering tank used in the heat treatment plant. Modified with a transistor thermostat controller and with the appropriate electrical control circuit, the temperature control accuracy of ± 1 degree. After more than three years of use proved that this improvement does have less power consumption, fast heating, high sensitivity, easy operation, safe and reliable.
