The apparatus comprises a purified water tank, a water tank I, a water tank II, an injector, connecting pipelines, and valve members. The water tank I is separately connected to the purified water tank and to the water tank II by means of a water suction pipeline and an intermediate pipeline. The water tank II is connected to a water-consuming component by means of a water supply pipeline. The upper part of the water tank I is separately connected to a vacuum-pumping port of the injector and a train gas source by using an exhaust pipeline and a water and gas supply pipeline I. The upper part of the water tank II is separately connected to the air and the train gas source by means of an exhaust pipeline and a water and air supply pipeline II. The water tank I is provided with a liquid level switch I and a liquid level switch II from top to bottom. The water tank II is provided with a liquid level switch III, a liquid level switch IV and a liquid level switch V from top to bottom. The apparatus can continuously supply water, reliably operates, needs low use and maintenance cost, and has no special bearing requirements on the purified water tank, and can be mounted on the bottom of a train as needed.
