　　防水卷材真空吸水仪结构特点：

　　主要由抽气部分，试验控制部分及试样容器部分组成，控制系统方便灵活，易于操作，整机布局合理，层次分明。

　　Structural features of waterproof membrane vacuum water absorber:

　　It is mainly composed of pumping part,test control part and sample container part.The control system is convenient and flexible,easy to operate,and the whole machine is arranged reasonably and clearly.

　　防水卷材真空吸水仪安装与调试：

　　开箱时注意各种玻璃容器是否破损，真空泵是否注到红点位置，各接头连接避免松动，个阀芯应涂真空至，将温度计及胶塞安装在储水瓶上，然后接通电源。

　　Installation and commissioning of waterproof membrane vacuum water absorption instrument:

　　When opening the box,pay attention to whether the various glass containers are damaged,whether the vacuum pump is injected to the red dot position,and the joints are connected to avoid loosening.Vacuum should be applied to each valve core.Install the thermometer and rubber plug on the water bottle,and then connect the power supply.

　　防水卷材真空吸水仪试验准备：

　　A、抽气系统检查，(充气时再开启注水阀)

　　储水瓶倒入少量的清水关闭注水阀，开启调压阀及抽水阀，启动使真空干燥器的真空度达到规定的数量，此时开启注水瓶内的水抽吸到干燥器中，以此检查抽气系统畅通无漏气。

　　B、试件处理：(卷材为例，瓷砖参阅**有关检测标准测试)时间不封边，将其表面浮动隔离材料刷除，并准确称量(W1)

　　Test preparation for vacuum water absorption meter for waterproof membrane:

　　A.Exhaust system inspection(open the water injection valve when inflating)

　　Pour a small amount of water into the water storage bottle to close the water injection valve,open the pressure regulating valve and the water suction valve,and start to make the vacuum degree of the vacuum dryer reach the specified amount.The air extraction system is free from leaks.

　　B.Test piece processing:(coiled material as an example,ceramic tiles refer to**Relevant testing standard test)Time is not sealed,brush the surface of floating insulation material,and accurately weigh(W1)

　　防水卷材真空吸水仪注意事项：

　　1、真空度负压严禁超过表量程而损坏表。

　　2、阀门塞心及干燥器接口处定期涂真空脂。

　　3、滴在干燥器真空脂上水需用滤纸粘吸。

　　4、因阀芯阵松而造成漏气。

　　5、定期更换泵油

　　Note for waterproof membrane vacuum water absorber:

　　1.Vacuum and negative pressure are strictly prohibited to exceed the meter range and damage the meter.

　　2.Regularly apply vacuum grease to the valve plug and the interface of the dryer.

　　3.Water dripping on the vacuum grease of the dryer needs to be sucked with filter paper.

　　4.Air leakage caused by loose spool.

　　5.Change the pump oil regularly
