Kamaz air brake system antifreeze
The anti-freeze protector is designed to protect the pipelines and devices of the pneumatic brake drive from freezing of condensate
Evaporative type fuse; it uses ethyl alcohol as a working fluid.
The main parts of the fuse are glass 2, body 6 with air channel A and jet 4, stem 7, seal 5 and wick 3 made of hygroscopic material, put on spring 1.
Beaker 2 serves as a reservoir for the working fluid (200 or 1000 cm3).
Jet 4 is designed to equalize the pressures in the air channel of the lid and the glass.
With the help of rod 7, pressed by spring 1, the fuse can be connected or disconnected from the pneumatic system.
When the rod 7 is on, it is in the upper position, the seal is removed from its seat, the wick 3 is inserted by the handle into the air channel A of the housing.
Compressed air from the compressor enters air channel A and carries away alcohol particles from the wick to the pneumatic system.
At the same time, part of the compressed air entering the fuse through the gap between the stem and the body, as well as through the nozzle hole, enters the glass.
Flowing over the surface of the alcohol, the air is saturated with its vapors.
In both cases, alcohol absorbs moisture from the air and turns it into condensate with a fairly low freezing point.
In the lower position of the stem 7, the wick 3 is recessed, the reservoir and the pneumatic system are separated by the seal and the evaporation of alcohol stops.
