To provide a suction vehicle loaded with a water-sealed vacuum pump capable of reducing size and weight of a suction device, having excellent cooling effect of the vacuum pump, and capable of maintaining high suction capacity over a long time.
This suction vehicle is constituted by loading a receiver tank and the suction device for reducing pressure in the receiver tank in the vehicle. The suction device is provided with the water sealing type vacuum pump and a dust collection device provided between the receiver tank and the water sealing type vacuum pump. The dust collection device is composed of a secondary catcher composed of a cyclone and a tertiary catcher composed of a water tank. A space in the inside of the receiver tank is partitioned, the space on one side is used as a recovered object storage chamber for storing a recovered object, and the space on the other side is used as a sealing water chamber for storing sealing water. These recovered object storage chamber and sealing water chamber are mutually communicated and connected through the secondary catcher, and the sealing water chamber constitutes the tertiary catcher and is connected with the water sealing type vacuum pump to supply sealing water in the inside into the water sealing type vacuum pump as cooling water.
