Vacuum truck (AKN-20) based on KAMAZ-6520 chassis is used for oil and petroleum gathering, gas-condensate, non-aggressive process liquids gathering, and their transportation for recycling.
Tankers AKN-20 may be performed for all climate zones, a sleeping berth is optional.
Tanker component parts:
- cistern ( circle cross-section, steel grade 09G2S),
- vacuum pump (КО-505, PNR-122, PVT-200, PVT-400, ВК-6М2, НВР-8/5 or ВР-8/3),
- electrical equipment,
- fire-fighting equipment (extinguishers, sand boxes),
- measurement equipment (vacuum manometer).
Vacuum truck specifications
Tanker AKN-20 is a cistern installed on “KAMAZ” chassis.
Cistern – is a welded construction of two bottoms and drum shell.
An operating platform with a non-slip perforated flooring is available on the tanker. A ladder is also pre- installed for comfortable lifting.
In the foot of the back bottom there is a flanged pipe with a filler flap. On a flap there is a butterfly valve, which makes the pipe opened or closed when turning. All connections are tight due to hermetical seals. The hose is attached to the filler flap with a coupling nut. The hose includes a delivery-suction hose DN 100mm, a coupling nut for connection with a filler, and a gasket.
Compressor is designed for creating vacuum during the filling and creating pressure during the discharge. A vacuum truck unit includes: vacuum pump, grease filter, moisture separator, pipe system with ball valves.
The pump drives from the chassis engine through the drive shaft.
The tanker is installed on a frame mounted support which combines with chassis. The supports are attached to a metal cradle structure which is fixed on a mainframe with U-bolts. Under the supports in cradles there are metal ribs which protect from crushing. Under a frame support there are ribbon springs.
Electrical wiring is layed through metal hoses, all connections are encapsulated, equipment is performed in explosion-proof configuration.
The tanker is provided with a warning sign “Flammable”. On a back side there is a ground circuit. 200 mm of it must contact the road surface.
