近年我们制成了一种标准养护室的自控恒温装置,使用效果很好。这种自控热水器适用于室温低于+20℃时加温、恒温。一、主要仪器设备白铁皮热水箱一个,800×150×500mm(长×宽×高); 自制白铁皮浮球式自动补水箱1个,400×350×350mm(长×宽×高); GYS_3型管状电热元件2个,220V/1 kW; 电接头式温度计1支,0～50℃; 普通酒精棒式温度计1支,0～100℃; 6301型电子继电器1台; CJO-40A型交流接触器1台。该装置电气线路如图1所示。二、操作过程合上电源开关,交流接触器线圈c通电后接通电加热器。当温度升到给定值(十20℃)时,电接头式温度计接点闭合,电子继电器内J通电,其常闭
In recent years, we have built a self-control thermostatic device for a standard curing room, which is very effective. This self-control water heater is suitable for heating and constant temperature when the room temperature is lower than +20°C. First, the main equipment of a tin hot water tank, 800 × 150 × 500mm (length × width × height); self-made tin metal float water tank 1, 400 × 350 × 350mm (length × width × height); GYS_3 type tubular heating element 2, 220V/1 kW; electric connector type thermometer 1, 0～50°C; ordinary alcohol stick type thermometer 1, 0～100°C; 6301 type electronic relay 1 set; CJO-40A type AC One contactor. The device electrical circuit shown in Figure 1. Second, the operation of the power switch is closed, AC contactor coil c power after the electric heater. When the temperature rises to a given value (20°C), the contact point of the electric connector type thermometer closes, and the electric relay J is energized and normally closed.
