The Flame Burners

Control device of the burners – a device which senses a flame burner controlled by them, the output of which there are signals that show the presence or absence of flame. The device control burner is the general case of the flame detector (sensor torch) and a control unit flame sensor (secondary device). The flame detector converts the light emission controlled burner flame into an electrical signal, and the block control processes the signal in accordance with laid down in its logic and produces a binary signal of the presence / absence of controlled flame burner. Optional control box flame sensor can provide signal intensity of the flame in the form of 0 / 4 … 20 mA, and binary signals on the status of devices for flame detection, and binary control signals for automatic burner control / whole unit. Since control the burner flame is directly related to the safe operation of equipment, the control unit of the flame – flame sensor must accurately identify the torch of "their" burner flame, and not to react other burners radiation and structural elements of the furnace.

(GOST 21 204 -97 Gas burners, industrial. General technical requirements: 4.2.8 The unit flame control should react only to the flame burner controlled and should not react to external sources of heat and light (incandescent lining, lighting, etc.). Flame monitoring device in the DURAG flame sensors and control units fully meet the high requirements of this devices. The main advantage of flame sensors and control units DURAG is the real selectivity and reliability of control of the flare. It is provided as follows: a special semiconductor photodetector with fairly narrow range of the received radiation spectrum for each type of jet fuel burned, a built-in multi-sensor flame signal amplifier, multi-stage (up to 99 steps, depending on model) filter the signal intensity of the glow torch, allowing signals to set the date of issue of the presence and extinction of the torch, multi-stage filter in the frequency of flickering torches, allowing in principle to cut off radiation other flames, dual redundant channel receiving and processing the signal from the flame sensor and advanced self-diagnostic system and self-control. The flame detectors and control systems DURAG flame can be divided by versions of compact control system plume (all in one case) and 'separate' systems (separate flame sensor, a separate secondary unit). In terms of selectivity of flame control – on the highly selective the system (Definition of their 'flame with a 100% probability) and a system with a simplified functional.

Connecting ssitemy cooling the mold with hose refrigerant source (thermostat, coolant, circulating guild line) is recommended to quick connections, consisting of a nipple and coupling. Elements of the cooling system, are usually present in the directories of manufacturers of standard parts for injection molds. In same time, there are companies that specialize in manufacturing cooling elements. Processing of the mold main part of processing elements of the mold is carried out on CNC milling machines and EDM machines.

Processing technology involves three stages of mechanical treatment, and three – heat treatment: Annealing – roughing – normalization – Finishing treatment – hardening – finishing – plating. Annealing required for any procurement of residual stresses; For roughing removed the bulk of the material, allowances for working surfaces – 0.5-2 mm. Normalization (annealing) is necessary to remove the main stress in the workpiece, it reduces the risk of large lead during quenching.

Crucible Induction Melting Electric

Induction crucible furnace designed for melting and overheating of steel and cast iron. Possible melting of nonferrous metals (bronze, brass, aluminum) and their alloys in a graphite crucible. It is used in foundries, steel factories, workshops precision casting and repair shops engineering plants to produce steel castings of high quality. Induction heating – heating bodies in an electromagnetic field due to the heat of the vortex electric currents flowing through the heated body and excited in him due to the phenomenon of electromagnetic induction. When the current in the heated product is called induced or induced current. Induction units called electrothermal devices for induction heating or melting metals. Induction furnace, induction melting furnace – electrothermal equipment for melting materials with using induction heating.

Induction furnace operates on the principle of the transformer, whose primary winding is water-cooled coil, secondary, and at the same time load – located in the crucible of metal. Heating and melting of the metal takes place due to the currents flowing in it, which is caused by the electromagnetic field generated by the inductor. Electric consists of the smelting unit and equipment set. Melting unit is designed in a supporting frame consisting of two racks welded construction site "setting inductor" and the two hydraulic rams. Inductor consists of two sections, each of which a multiturn coil water-cooled, made of copper rectangular tube. Supply to the inductor power and water by using water-cooled flexible cables connected to it sequentially.

Hydraulic rams provide slope to drain metal furnace at an angle of 95 for 20 seconds. Managing tilt the furnace by an electric control valve, control panel, the slope of the furnace installed on site. Induction furnace is fed from the network through thyristor frequency converter TPCH, which is designed to convert three-phase industrial frequency AC high frequency. The main advantage of thyristor Electrically before is because of the lack of no-load losses reduced potreblaemaya power, increased efficiency, lower operating costs. Supply voltage converter comes from the transformer. Electric power is controlled by changing the voltage at the output of the converter and automatic frequency control in the smelting process. On front of the transducer placed controls, security alarm and control of the converter. In the control cabinet and authorities are signaling the remote control thyristor converter and control equipment and alarm systems. The cabinet mounted cooling water monitoring sensors and alarm systems cooling electric furnaces and condensers. Status of the lining of the crucible is monitored visually and by periodic measurements of the inner diameter of the crucible. Control over the work by using electric instruments and controls, located on the cabinet front panel controls and alarm systems.

The Test Results Bucket Active Action

At the entrance tooth excavator bucket in a layer of frozen ground attack units included in the action, but not always worked at the same time all three units, since a decrease in the teeth of the efforts going on a short-term alternate disabling one of the blocks. Energy intensity of the development process of frozen soil scoop active action powered by a compressor was 0.111 kWh/m3, powered by two compressors – 0.081 kWh/m3 and serial Bucket dredge in non-frozen ground – 0.026 kWh/m3. Location shock of teeth on the cutting edge of the excavator bucket, selected on the basis of earlier studies (distance between axles 350, the tooth width 150 mm), guarantees constant contact with the edge of the array intact, as evidenced by the experimental values of the resistance force digging. During the development of frozen soil using a single compressor station pressure dropped from 0,7 to 0,4 MPa. The energy shock pnevmomolotov decreased, there was an increase of emerging efforts and had to decrease the thickness of the destroyed layer. If you have two compressor stations essential pressure drop was not observed, however, when performing other operations Excavating cycle compressor stations used inefficiently. Therefore, the results of the trials was asked to use one compressor station with a receiver. For more information see Brad Pitt. Calculations showed that for average soil conditions are sufficient to have a receiver volume of 2 m3. When working on the frozen ground on the track excavator to install the spikes, available in the maintenance kit, to prevent sliding tracks on the soil surface and fall to the bottom dredge.
