樺甸頁岩油公司技术研究所在技术革新与技术革命运动中,改革和自制了不少代用试验仪器。现将恆温自动控制器介紹如下。恒溫自动控制器的构造如图所示。当汞柱受热后,水銀上升与电源接触,接通电路,使电磁铁发生作用,把弹簧片吸上,这样就切断了加热器的电路,使停止加温。当温度下降后,水银收缩,使与电源切断,电磁铁失去作用,因此弹簧片回到原处,将加热器与电源接通,又开始加温。这样就可以使溫度控制一定,其波动范围可在±1—2.5℃。汞柱球毛細管越細則越灵敏。汞柱线路上还可串联一个或几个小电阻來调节。
Huadian Shale Oil Company Institute of Technology in technological innovation and technological revolution movement, reform and self-made a lot of substitute test equipment. Now the thermostat automatic controller is as follows. The structure of thermostatic automatic controller is shown in the figure. When the mercury column is heated, the mercury rises in contact with the power supply, the circuit is turned on, the electromagnet is activated, and the spring plate is sucked up, thus cutting off the heater circuit and stopping heating. When the temperature drops, mercury shrinks, so that the power cut off, the electromagnet loses its role, so the spring back to the original place, the heater and power connected, began to heat. This will make the temperature control a certain range of its fluctuation can be ± 1-2.5 ℃. Hourglass capillary thinner the more sensitive. Hg line can also be series with one or a few small resistance to adjust.
