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.

KG. (Germany), Synventive Molding Solutions (USA, Netherlands), Watlow Company (USA), Heatlock (Sweden), etc. As a rule, the production of hot runner systems for these enterprises is associated with the production of temperature controller for them. There are also companies that specialize in production only for hot runner controllers. These companies include: Athena Controls, Inc. (USA), PMS Systems Ltd (UK) and other elements of the system cooling cycle of casting more than 50% consists of a fan belt casting.

For soszdaniya reliable in the system cooled the mold tech in manufacturing and maintainability in service, offers a variety of standard components: quick-connect, play, fortaniruyuschie tube, turbulence, heat Trebkov, Heat Sink marks, seals, zglushki and cork. 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.

DVD Russian

With DVD Russian citizens met at the end of the last century, in 1997. Since then much has changed, the market settled down a large number of different manufacturers and different versions. If you go to shopping mall, which sells equipment of this type, then run into the problem of choice, but not because selection is scanty, the opposite is true – the proposed range of DVD is very rich. And each customer would like to receive device that not only would be the best, but also cost is not too expensive. Of course, you can pay attention to the best-selling dvd-players, and decide for yourself what is the best option. Most likely, so you go straight to the target. But there are things about which you should definitely know. You know – to get good and cheap DVD to be very much taken into account.

But in this article we would like to focus on multi-zone and some functionality. Well, let's start. Read more here: Brad Pitt. Choose a multizone player. On land there are zones in which the world was divided in 95th, each zone has its own drive type, designed for the area, and they played can only player in this zone. But after a while began to produce DVD, which perceive the wheels of all zones. Your only a DVD. Now on to the. In some there is automatic adjustment of DVD, on the one hand not bad – no need to once again to bother.

And if you do not like the way your player is configured, the settings do not suit you? The conclusion suggests itself – manual setting is preferred. There are those who mistakenly believes that this function is not needed, and that he is capable of DVD 'stretch' the image and make it better than the picture on the TV screen. That may be so, but at the same time too many models overestimate the color. So here as a manual adjustment time and necessary, it makes it possible to configure it right. Many types of players allow you to adjust such parameter as 'range', responsible for the reproduction of dark scenes, dark fragments. You can adjust the delay relative to the color of the picture. How coherent is the signal between the DVD and projector, depends precisely on these points. By the way, if you still and pay attention to the choice of the latter will simply wonderful. There are many variations – expensive projectors, cheap, selling, modern. But not everyone will be able to smoothly run a hundred percent with dvd-player, who do you have in stock.

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. Main advantages of induction melting furnaces ITPE: In the manufacture of ovens used new clean and high quality materials, asbestos is not used. More robust components – Czech and German mid-capacitors. In furnaces used reliable thyristor frequency converters a new generation of automatic frequency control during melting. High power of fusion. Calculated and optimized selected inductance of inductors and trunk capacity of capacitor banks, the losses in the furnace circuit is minimized, resulting in achieved: higher productivity, greater efficiency in energy consumption, higher efficiency furnaces. In the production of electric current applied advanced technology. Rods of hydraulic cylinders are protected from the metal spray. Significantly increased and reliable operation of the furnace.

Fusarium Planted

Given the large areas of FG 'Adelaide' begins to plant potatoes with early-stage and ends at the optimum. The farm is used protectant "Rovral Akvaflo" to protect potatoes from: Rhizoctonia, Fusarium, superficial necrosis, dry and wet rot. As an alternative to fungicide use "Maxim". At the time of planting potatoes is possible to use drugs "Prestige," "Masterpiece," "Tyrant," have fungicidal and insecticidal action. Tubers infected with highly mutually sort, so preparations, applied to the surface of tubers, is a kind of protective shield against harmful organisms. Planting crops are potato GRIMME GL 34 T, which has standard equipment. Potato trailers, 4 rows, 75 cm row spacing, 4 support the wheel, 3-ton capacity hopper parallelogram suspension openers, tractor capacity of more than 80 liters ..

The farm potatoes are planted in wide method followed by the formation of ridges, ie, in the process of landing is not formed a high crest, and subsequently formed the crest of the correct height. Tubers are planted at a depth of 6-8 cm from the top of the ridge, followed podgrebaniem soil. It is essential that the tubers were planted at the same level doposadochnoy the soil surface. It should be also take into account the fraction of the tubers are planted in large fractions of 2-3 cm deeper than the smaller ones. When planting the tubers too deep of a new crop are located deep, which makes mechanical harvesting. Properly conducted planting of potatoes, and predicts the amount of harvest and ripening time, as well as provide a convenient and quick cleaning. As a result, we have a beautiful, uniform potatoes, without mechanical damage and disease who gladly offer to sell yourself and eat. More information on FH "Adelaide
