The cooling device 4 is a heat exchanger, the cooling device 4 is filled with cooling oil, and the cooling device 4 can reduce the temperature of the cooling oil.
本实用新型的工作过程如下：打开釜盖3，将待测试水泥浆装入于釜体1中，随后盖合釜盖3。The working process of the utility model is as follows: open the kettle cover 3, put the cement slurry to be tested in the kettle body 1, and then close the kettle cover 3.
当测试高温水泥浆时，经控制器控制加热装置8启动，加热装置8对釜体1内的水泥浆加热，温度传感器将水泥浆的温度信号转换为电信号并传递给控制器，当到达测试温度时，关闭加热装置，从而测试该设定温度下水泥浆的凝固时间；通过改变加热装置8的加热时间，能够实现不同加热温度下水泥浆的凝固时间。When testing high-temperature cement slurry, the controller controls the heating device 8 to start, and the heating device 8 heats the cement slurry in the kettle body 1.
