[0002] The apron refueling pipe network system is an important facility for aircraft refueling operations. Whether the layout planning and operation management of the refueling well plugs are scientific, economical and practical directly affects the safe and efficient operation of the refueling system. In order to ensure the long-term normal use of the refueling well plugs, it is necessary to regularly maintain and clean the refueling well plugs. The refueler is responsible for the regular maintenance and cleaning of the ground plug well equipment. After long-term maintenance and cleaning of equipment and facilities, the experience is summarized. During the operation process, if there is a small amount of water and impurities in the plug well when it is due for cleaning, it is recovered with cotton rags and aluminum oil drums. The operator needs to bend over or crawl on the ground to perform the cleaning operation.

[0003] When the rainy season comes and there is a lot of rain in the bolt well, a cleaning truck oil pump is used to recover the water. After recovery, there will still be a small amount of water and impurities at the bottom of the ground bolt well, which need to be recovered using cotton rags and aluminum oil drums. The operators still have to bend over, crawl on the ground, wipe with a rag, wring it out, and repeat this action many times to clean the well.

[0004] Therefore, a vacuum explosion-proof self-priming pump device is particularly needed to solve the problems existing in the prior art. Utility Model Content
