aircraft sewage truck is composed of Qingling Class II chassis modification assembly, water tank assembly, fixed platform, lifting work platform assembly, hydraulic system, electrical system, etc.

JSTY5070GWS aircraft sewage truck is composed of Qingling Class II chassis modification assembly, water tank assembly, fixed platform, lifting work platform assembly, hydraulic system, electrical system, etc.

1. Chassis

The chassis is modified by the second class chassis of Qingling, and its structural performance can be used and maintained by referring to the operation manual of the second class chassis of Qingling.

The company carries out local modification according to the product design. The rear end of the girder is welded with a working platform frame, the left side of the platform frame is a ladder, which is used for staff to go on the box maintenance and sanitary cleaning, and the right side of the platform frame is a cleaning pipe conveying device. A water pump, water inlet pipe, hydraulic pump and hydraulic accessories are installed on the right side of the girder, and a fixed diesel tank and hydraulic oil tank are placed on the left side of the girder.

2, water tank assembly

The water tank is made of 4mm 304 stainless steel plate, and the box is composed of three completely isolated water tanks: circulating water tank 240L, which provides circulating water for the vacuum pump; Water tank 1400L, providing water to the aircraft, the top of which is provided with a round manhole cover; Sewage tank 2400L, storage of sewage discharged from the aircraft sewage tank, is divided into two identical compartments by the water baffle, the top of the tank is provided with two circular manhole cover, two breathing valves, when the vacuum degree reaches the rated vacuum pressure of the box, breathing valve begins to inhale from the outside of the box to the inside of the box, so as to ensure the safety of the box, the bottom is provided with a sewage outlet, The end face of the sewage tank is provided with a sewage observation window, which can observe the sewage level in the tank. The box is connected with the chassis through 6 rubber shock absorbers, which can well buffer the vibration of the water tank during the movement of the car. The upper surface of the water tank has imported anti-slip stickers, which can prevent the operator from slipping during operation and maintenance on the water tank. The interior of the cleaning and sewage tank is equipped with a "well" shape water baffle to prevent the impact and agitation of the water flow in the vehicle.

The water tank is equipped with a stainless steel anti-swing plate with a thickness of 4mm, to avoid shaking when the vehicle is running after the water tank is added, and the welding is firm, the layout is reasonable, and it is easy to clean; The top of the water tank is separately provided with an air vent valve. The two water tanks and the car girder are fixed in the form of rubber cushion connection, which reduces the vibration of the box when the car is driving.
