The invention relates to the technical field of civil aviation aircrafts, and discloses a drainage method of an airplane water system, which comprises the following steps: S1, opening all drainage ports until no water is discharged from the airplane water system under the action of gravity; s2, any water outlet below the machine body is connected with negative pressure water drainage equipment, and all water inlets and other water outlets below the machine body are closed; s3, setting the negative-pressure drainage pressure of the negative-pressure drainage equipment at the drainage port; s4, opening water utilization equipment at each position in the aircraft, so that each position of the aircraft water system and the negative pressure drainage equipment form a passage through the drainage port; and S5, the steps S2-S4 are repeated, and the negative-pressure drainage equipment is sequentially connected with other drainage ports below the aircraft body till residual water in the aircraft water system is completely drained. The method has the beneficial effects that the drainage efficiency is improved, the workload of an airline department is reduced, no residual water in a water system is ensured, the drainage cost is reduced, and the carbon emission is reduced.

    本发明涉及民航飞机技术领域,公开了一种飞机水系统的排水方法,包括步骤:S1、打开所有所述排水口,直至所述飞机水系统在重力作用下无水排出;S2、机身下方任意一排水口连接负压排水设备,并关闭机身下方所有加水口和其它排水口;S3、设定所述负压排水设备在排水口的负压排水压力;S4、打开飞机内部的各处用水设备,使所述飞机水系统各处通过所述排水口与所述负压排水设备形成通路;S5、重复步骤S2‑S4,将负压排水设备与机身下方的其它排水口依次连接,直至将所述飞机水系统内残留的水排净。本发明的有益效果:提高排水效率,降低航线部门的工作负担,确保水系统内无残留水,同时,降低排水成本,减少碳排放。
