响执行器的正常工作。对防护而言,做不好的防护还不如不做,假如不做,遇到枯燥的气候,被防护的器件四周还能够是枯燥的(

Secondly, water-proof batteries are used in batteries, which are also treated as water-proof batteries in appearance, but it is unknown that there is still a leak in the junction used for battery replacement (some manufacturers are happy to stop setting the replacement battery connection line and connect the battery connection with the circuit board directly. How to change the electricity? Pool? Therefore, the current battery protection of smart water meters is not qualified.

再者,目前很多厂家都用少量的涂胶方法对执行器的防护,我们权且不谈目前大局部厂家所运用的胶是多孔胶(譬如704胶),基本防不住空气中水分和氧气的进入。就从涂胶的效果来看,由于存在其不平均性等要素,这种办法也是防不住空气中水分和氧气的进入的。一旦有空气中水分和氧气进入执行器内部,其内的金属(铜件和铁件)件就会被腐蚀生锈,从而影响执行器的正常工作。对防护而言,做不好的防护还不如不做,假如不做,遇到枯燥的气候,被防护的器件四周还能够是枯燥的(

Moreover, at present, many manufacturers use a small amount of glue coating method to protect the actuator. We can not say that most of the glue used by manufacturers is porous glue (such as 704 glue), which can not basically prevent moisture and oxygen from entering the air. From the effect of glue coating, because of its inequality and other factors, this method can not prevent moisture and oxygen from entering the air. Once moisture and oxygen in the air enter the actuator, the metal (copper and iron) parts will be corroded and rusted, thus affecting the normal operation of the actuator. As far as protection is concerned, it's better not to do bad protection. If not, in the face of dry climate, the device protected around can also be boring. http://www.sdlyxqyb.com/
