Gas infrared heaters are simple devices and services, low thermal energy, regulation of output power over a wide range by changing the gas pressure supplied to the mixer burner. Disadvantages of - the possibility of blowing the flame with wind speeds of more than 6-8 m / s, relatively short period of service, additional activities on safety, as support staff to work [...]
The energy balance of these machines in operation include (depending on the technology works): the cost of power to drive the bitumen pump, defined as vehicles for transporting and distributing bitumen, cost of power to drive the compressor is defined as machines that destroy the hard cover, the cost of power to drive the mixer to be taken when mixing the mastic in the boiler with a capacity of [...]
Machine DE-10 is a mobile cart with a manually controlled located on it termoinstrumentom and fuel tank. Compressed air is the working body and the fuel tank is fed from an independent compressor and an electric current to ignite the combustible mixture in the combustion chamber of the burner - the car battery. Asphalt concrete pavement cut the gas stream at a temperature of 1000 ° C, cutting [...]
The most frequently snow-ice reel or ice formed by the long-term presence of snow on the shaft prilotkovoy band, resulting in sharp fluctuations in ambient temperature (alternating plus and minus temperatures), less frequently, on the roadways due to delayed and poor harvest from it compacted snow. Can most effectively influence the regelation rolling snow-ice, or ice from the pavement preventative [...]
When working with gas burners razogrevateley type of radiation should be opened before the ignition supplies valves on cylinders and gazoraskhodnoy column and gauges to check the pressure in the systems of medium and low pressure, medium pressure shall not exceed 0.16 MPa, the low - 0,002-0,0035 MPa . After checking the pressure should be light igniter and bring it to the emitter of each burner. [...]
For sealing cracks in the pavement as asphalt distributor used car ED-10A. It is based on the chassis of GAZ-53A consists of the following major components and systems: tanks for bitumen, two bins for sand, Swing bin, filling bitumen system, pneumatic, fuel and hydraulic systems, spetskabiny, left and right side, and rear boxes, electrical equipment.
