Technical features of the vacuum unit

Tank truck AKN-7,5-tank mounted on the man TGL.

The tank is a welded structure with two bottoms and sides of a round shape.

The tank has a maintenance area with an anti-slip surface in the neck area. For a comfortable ascent to the platform there is a staircase.

At the bottom of the rear bottom of the tank welded pipe with a flange, which is mounted on the folding bolts receiving hatch. It consists of a cover on which the handle with a disk fastens, at turn of the handle there is an opening or closing of the hatch. Tightness of connections is achieved by seals. A sleeve is attached to the receiving hatch with a cap nut, which consists of a pressure-suction sleeve DN100 mm, a cap nut for connection to the hatch, a gasket and a tip.

The compressor is designed to create vacuum in the tank during filling and pressure during discharge. Vacuum installation system includes: vacuum pump, oil separator, dehumidifier, pipeline system with ball valves.

The pump is driven from the chassis engine through the propeller shaft.

The base of the tank is made of supports on the frame and is designed for mounting to the chassis. A support joined to the metal cradles that are attached to the frame rails, truck step ladders. To save from collapse under the pillars in the cradle is a metal stand and ribs. Under the support of the tank are placed rubber shock absorbers.

The electrical wiring is laid in the metal hose, all electrical connections are sealed, the devices are made in explosion-proof design.

The tanker has a warning sign “Flammable”. To the rear there is a circuit of camp ground. The 200 mm chain must touch the road surface.
Versions:

Belt fastening of the tank to the chassis.
Quick-release technological hatch for tank cleaning.
Additional filler neck at the rear of the tank (with calibration certificate).

Four-circuit lighting system of the working area.
Tool box (own production) on the rear overhang of the car frame.
