Description

Rat with heater and heat insulation ggakidkoy.

The apnarat contains a satchel / in which the air and oxygen supply systems are located. The air duct system contains a mouthpiece box with aaryonit 2, attached nglangs O and 4 15 Wett and W .., regenerative Iatron 5, cis: p; kenyy absorber, connecting chamber C, breathing bag 7 with excess claian 8, breath 8, 9 Ho lnik /; l In the connecting chamber nos.ge) of its emerativnogo cartridge located on the blower 11.

The oxygenated donor system contains K; a cylinder 12 with a valve 13, a reducer 14, a diaphragm lung automaton 15. Clavian 16 emergency oxygen pump, a pressure gauge 17, and a shut-off valve 18.

The heater consists of a gas explosion and is safe; the catalytic burner 10, the housing of the heater 20, the cylinder 21 with the shielded propane-butane gas and gas {unit 22.

Go,} the Christmas tree is equipped with a gas blower and, with it, a 2.7 tube for the nodvod of iroian-butane mix. The gearbox is connected to the burner through a metering orifice. The heat burner burner is controlled by changing the working pressure in the gearbox, which is determined by the pressure and pressure of the shaft 24.

In parts of the corus heater, there are louvres for the air supply to the burner. The heater is attached to the lower part of the air cleaner with pins, dvg, ii3 of which are mounted on the housing of the cleaner from the side of the spray, and odip - on the cover of the respirator.

For partial thermal insulation of a respirator with a heater and formation of the air heat flux created by the heater around the respirator, heat is applied. The heat and ash of the pion cape 25 is made of poroloy and is sheathed on both sides with a flame retardant elastic with leather. For (thermal heat flow around the respirator satchel on the inner side of the sleeve) fixed distant figured struts 26. The maquid covers the respirator and fastens on the chest of the respirator with the help of a collar and four straps.

The procedure for turning on the heating is as follows.

The obsm-checker must be placed from the actuator and the gearbox lever should be put in the “Forced mode (there are three fix levers on the heater body 24 -

roovainy.k to position

"Turned off," Operating mode and "Forced poiaLM), open the flame of the torch to heat the burner to those of the first hole (within 5-10 .1shn), and the gas flashes on the surface, indicating that the burner burns the temperature and switched to catalytic combustion mode. After that, it is necessary to move the gear lever to

“Operating mode, connect the heater to the respirator and put on the insulating cape. Apiarat is ready for work. Thus, the use of an external heater in combination with a teloizol and OO1 cape provides a guaranteed period of action and normal microclimatic respiration conditions at ambient temperatures up to 50 ° C. Respirator without heater

the duration of the protective effect is halved.

Form m l l a and 3 o r e t e n i

Leroch.no-avto.chatcheskny breathing apparatus with a device for continuous blowing of the auth. St. 227851, distinguished by the fact that, in order to increase the operating efficiency of the device in low temperatures, it is equipped with a heater fixed in the lower part of the housing, made in the form of a gas explosion-proof catalytic burner connected to a cylinder of liquefied gas through a gas reducer.
