The main function of intrinsic barriers – is to ensure the safe connection and operation are installed in hazardous areas of simple sensors and devices with power consumption and power consumption is not higher than allowed, and also more energy-intensive equipment permitted for use in hazardous areas and has the appropriate type of protection. Now widely used two types of barriers, intrinsic safety: the shunt diodes and electrically isolated. Check with to learn more. The wiring connectable to electrical equipment with a type of protection "intrinsically safe", must meet the following requirements: 1) intrinsically safe circuits must be separated from other circuits in compliance with GOST 22782.5-78 * 2) use a single cable for iskroopasnyh and intrinsically safe circuits is not allowed, and 3) wire intrinsically safe circuits of high frequency should have no loops, and 4) wire insulation intrinsically safe circuits should have a distinctive blue color. Allowed to mark only the blue wires, 5) wire intrinsically safe circuits must be protected from interference that violate their Intrinsic..
Parovozdushnoformalinovye fumigatory Series CD / efficiency: a modern alternative to the hopelessly outdated domestic fumigatory View Manufacturers, the cost of disinfection which is commensurate with the cost of new products in fumigatory CD / COP (fumatorium) applies steamair (physical) method of disinfection of water line enters the steam generator into steam and the steam enters the disinfection plant. In the upper part the camera body in the entire area of the ceiling heater is located, in which using the 'dry' TEN-s heats up the air. The radiator is separated from the rest of the room air collectors, which is a hollow box. Air from fumigatory through the longitudinal slit in the bottom of the box goes to the air collector, whence through a hole in the center of the ceiling air collector by the fan sucked into the radiator. The heated air from the heater to the same fan is thrown back into the chamber through nozzles located along the side walls of the chamber. -Steam mixture is formed as follows: steam enters the disinfection plant and rises, through the longitudinal slit air collector fan is sucked into the radiator, where together with heated air through the nozzle is released again into the camera, etc.
This principle ensures uniform mixing of vapor and air in the entire volume camera. At the time of drying the steam solenoid valve is closed and the chamber is circulated only to the hot dry air. To remove a pair of nozzles fumigatory heater valve off with a lever located outside of the side walls. Opened the valve on the air duct to the air cooler and radiator fan from parovozduh blown through the ductwork. After a couple skondensirovaniya latches on the duct is closed, and the nozzle heater is opened, and the hot air from the radiator through the nozzle is fed straight into fumigatory. (fumatorium) Processed objects are placed on carts, made of aluminum tubes, which through ramps open-catchers on the rails inside the closed chamber and the roll out of it.
