, 用吹尘枪或扫帚清理蘑菇头 , 只有砂粒全部进入罐体后才能打开气阀送气 , 防止砂粒磨损 O 型圈和蘑菇头 . 4) After all the abrasive has entered the tank , use a dust blower or broom to clean the mushroom head . Only after all the sand particles have entered the tank can the air valve be opened to prevent the sand from wearing the O -ring and the mushroom head .

, 不能用锤子 , 扳手或其它重物硬物敲击罐体或喷枪 , 应采用其它相应措施来处理和清理 , 应该停止作 5) During the operation, the sand blasting is interrupted due to failure . Do not use a hammer , wrench, or other heavy or hard objects to strike the tank or spray gun . Other corresponding measures should be used to handle and clean up .

, 卸掉罐体气压后再进行处理 . Industry , remove the tank air pressure before processing .

, 高压状态时 , 不能随意移动 , 敲击 , 插拔气管和喷枪 , 否则会引发危险 , 造成事故 . 6) When the blasting pipe is under pressure and high pressure , it cannot be moved freely , knock , insert or pull out the air pipe and spray gun , otherwise it will cause danger and cause an accident .

, 因此需要一定的时间才能自喷嘴喷出 , 所以在调节砂阀的砂量大小时 , 调节手把的频率要 7) Because the abrasive has a certain distance to the nozzle through the sandblasting tube , it takes a certain time to spray from the nozzle . Therefore, when adjusting the sand amount of the sand valve , the frequency of the handle should be adjusted.

, 要边观察边调整 ( 调砂阀喷枪不能对准人和物 ). Slower , adjust while observing (the sand control valve spray gun cannot be aimed at people and objects ).

, 滤掉水分和油雾的压缩空气 , 并且保证良好的压力 , 压力不能超过 8KG/ 平方 (0.7MPa). 8) It is said that the compressed air used must be a few sad filters , filter out the water and oil mist compressed air , and ensure good pressure , the pressure cannot exceed 8KG / square (0.7MPa).

1/3 的磨料 . 9) Never use abrasives with a sand diameter larger than 1/3 of the nozzle diameter .

, 旁边也不能站人 . 10) Sandblasting is absolutely prohibited .

, 在喷嘴口径磨损增大后 ( 一般超过 1.5MM) 应该进行更换 . 11) The nozzles of different calibers are reasonably selected according to the flow of the air compressor, and should be replaced after the wear of the nozzles has increased ( usually more than 1.5MM) .
