Three principles

The main parts are mostly made of high-quality stainless steel, which can withstand high temperature and high pressure saturated water vapor. The lid of the kettle is equipped with a pressure indicator made of stainless steel, a safety valve and two air release valves. The kettle body is installed in the shell, and two heating resistors are installed on the outer lower part for heating the kettle body to produce water vapor. The bottom tube is connected with the electric contact pressure gauge, and the electric contact pressure gauge cooperates with the electrical control system. In order to control the pressure in the kettle within a set range. The upper part of the shell is provided with a ventilation ring, and the lower part is provided with a ventilation plate for blocking or opening the air around the kettle body. An exhaust fan is installed at the lower part for exhausting and cooling after the test. The control box panel is provided with a main power switch, three keys for start, stop, and fan, and four indicator lights for running, heating, fan, and stop, and a digital display time relay for timing.

四、安装步骤：

★应安装在比较僻静的地方，为保证安全及使用维护方便，应背向墙壁， 离墙不少于 500mm，并调整水平，将其固定在地基上。 

★用不小于 1.5mm2 的软铜线将可靠接地。 

★连接好控制箱与釜体间的航空插头。

五，水泥压蒸釜操作规程：

★ 打开釜盖，按釜体容积 8.5L 的 7%~10%的注水量，即 595cc~850cc 蒸馏水 注入釜内。 （通常建议注水量：700 毫升~800 毫升） 

★将装有试件的支架放入内。 

★用棉纱将釜口和釜盖的密封面擦干净， 再用毛笔在釜口密封面上薄薄涂上一 层干净的机油。 

★轻轻盖上釜盖，下压并左右转动釜盖，确认结合部已正确密合。将 10 个螺 母用手拧上。再用扭力扳手按照 50、100、100Nm，分三次按对角线的顺序均匀地拧紧 螺母，安装好釜盖。 

★向釜盖中的温度计插管内注入 3~5 滴机油 （一般以油面不高于温度计水银 球为宜） ，将 300℃水银温度计轻轻插入管内。 

★打开两个放气阀中的任意一个。 

★将电接点压力表的红色上限指针调至 2.025MPa 处 （即： 2MPa 再上调半格） ； 将绿色下限指针调至 1.975MPa 处。 

★关闭通风盘和通风环。 

★接通电源，打开控制箱上的电源总开关，按启动键，运行、加热指示灯亮， 釜体开始以 1800W 功率加热。同时数显时间继电器开始显示。 

★ 当已打开的一个放气阀有水蒸气排出时， 说明内空气已经排净， 关闭该放 气阀。 阀门关闭后，压力将随着温度的升高而升高此时应注意，仪器工作有无异常，如有异常，则必须查明原因，或按停止键停止试验。 

★停止加热后，风机自动工作，信号灯亮，打开通风盘和通风环，通风环处会 有热空气排出，釜内压力将在 90min 以内降至 0.1MPa 以下。此时可打开放气阀将釜内 余压放净。请不要关闭放气阀，因冷却后会造成釜内负压，而损坏压力表。 

★ 待冷却至常温后，按停止键，信号灯灭、排风扇停，关闭电源总 开关，取下温度计，以安装釜盖相同的方法拧下 10 个拴紧螺母（拧松螺母时至少要用 两个循环，以免损坏密封结合面） ，取下釜盖，取出试件支架。用胶管或毛巾将釜内蒸 馏水析出擦净。 

★中途停止试验程序：按“停止”键，打开通风盘、通风环，按“风机”键， 待仪器冷却后重新安装试验。

Fourth, the installation steps;

★ It should be installed in a relatively quiet place. In order to ensure safety and convenient use and maintenance, it should be facing away from the wall, not less than 500mm away from the wall, and adjust the level to fix it on the foundation. Zh

★ Use a flexible copper wire no less than 1.5mm2 to reliably ground. Zh

★ Connect the aviation plug between the control box and the kettle body.

Five, cement autoclave operating procedures:

★ Open the lid of the kettle and fill the kettle with 5% to 7% ~ 10% of the volume of the kettle, that is, 595cc ~ 850cc of distilled water. (Usually recommended water injection volume: 700 ml to 800 ml)

★ Put the bracket with the test piece in it. Zh

★ Wipe the sealing surface of the kettle mouth and the kettle cover with cotton yarn, and then apply a thin layer of clean oil to the sealing surface of the kettle mouth with a brush. Zh

★ Gently cover the kettle lid, press down and turn the kettle lid left and right to confirm that the joints are properly tight. Screw in 10 female screws by hand. Then use a torque wrench to tighten the nuts evenly in a diagonal sequence in three times according to 50, 100, and 100 Nm, and install the kettle lid. Zh

★ Inject 3 ~ 5 drops of engine oil into the thermometer cannula in the lid of the kettle (generally, the oil level should not be higher than the thermometer mercury ball), and gently insert a 300 ℃ mercury thermometer into the tube. Zh

★ Open either of the two air release valves. Zh

★ Adjust the red upper limit pointer of the electric contact pressure gauge to 2.025MPa (ie: 2MPa and then increase it by half a division); set the green lower limit pointer to 1.975MPa. Zh

★ Close the ventilation plate and ventilation ring. Zh

★ Turn on the power, turn on the main power switch on the control box, press the start key, the running and heating indicator lights up, and the kettle starts to heat at 1800W. At the same time, the digital display time relay starts to display. Zh

★ When water vapor is discharged from an opened air release valve, it means that the internal air has been exhausted. Close the air release valve. After the valve is closed, the pressure will increase as the temperature rises. At this time, pay attention to whether the instrument works abnormally. If it is abnormal, you must find out the reason, or press the stop button to stop the test. Zh

★ After the heating is stopped, the fan will automatically work, the signal light will be on, open the ventilating plate and ventilating ring, there will be hot air discharged from the ventilating ring, and the pressure in the kettle will drop below 0.1MPa within 90min At this time, you can open the air release valve to release the residual pressure in the kettle. Please do not close the air release valve, as it will cause negative pressure in the kettle after cooling and damage the pressure gauge. Zh

★ After cooling to normal temperature, press the stop button, the signal light goes out, the exhaust fan stops, turn off the main power switch, remove the thermometer, and unscrew the 10 captive nuts in the same way as installing the kettle cover (when loosening the nut, use at least two Circulate so as not to damage the sealing joint surface). Remove the lid of the kettle and take out the specimen holder. Use a hose or towel to clean out the distilled water in the kettle. Zh

★ Stop the test procedure halfway: Press the "Stop" key to open the ventilating plate and ventilation ring, and press the "Fan" key. After the instrument has cooled down, reinstall the test.
