供粉状态：升降机构91向下运动直到吸粉管92插入粉末，文丘里粉泵93的送粉气开始供气，在送粉气的作用下，吸粉管92内腔内会形成负压，粉桶94内硫化的粉末在此负压抽吸作用下由吸粉管92输送到粉泵93、出粉管95，最终将粉末输送到喷枪96。Powder supply state: the lifting mechanism 91 moves downward until the powder suction pipe 92 is inserted into the powder, and the powder delivery gas of the Venturi powder pump 93 starts to supply air. Under the action of the powder delivery gas, a negative pressure is formed in the inner cavity of the powder suction pipe 92. The vulcanized powder in the powder barrel 94 is transported from the powder suction pipe 92 to the powder pump 93 and the powder outlet pipe 95 under the suction action of this negative pressure, and finally the powder is transported to the spray gun 96.
清理状态：送粉气停止供气，人工移开粉桶94，升降机构91向下移动使吸粉管92插入清理气包组合97的密封圈971内，高压清理气从清理气包组合97向吸粉管92、文丘里粉泵93、出粉管95内吹入清理空气清理吸粉口到文丘里粉泵93、喷枪96之间的粉末路径内部表面。Cleaning state: the powder delivery air supply stops, the powder barrel 94 is manually removed, the lifting mechanism 91 moves downward to insert the powder suction pipe 92 into the sealing ring 971 of the cleaning air bag combination 97, and the high-pressure cleaning air is blown from the cleaning air bag combination 97 into the powder suction pipe 92, the Venturi powder pump 93, and the powder outlet pipe 95 to clean the internal surface of the powder path from the powder suction port to the Venturi powder pump 93 and the spray gun 96.
此装置的缺点：在清理时需移动开粉桶，操作不方便；升降装置驱动吸粉管插入清理密封圈内，运动机构结构复杂，且操作繁琐。The disadvantages of this device are: the powder barrel needs to be moved when cleaning, which is inconvenient to operate; the lifting device drives the powder suction pipe to insert into the cleaning sealing ring, the movement mechanism structure is complex, and the operation is cumbersome.
