Ethernet System

To implement the RF control module has a radio receiver 433 MHz, and for GSM / GPRS connection – Built-in industrial phone. In addition, the module is GPRS-T3 jack for connecting an external microphone (Jack 3,5 mm), so that security of the GSM system can perform audioverifikatsiyu: after receiving a disturbing SMS-ku, the user can call a module number and listen to the protected object. To send control signals to the peripheral security equipment modules are equipped with two programmable relay outputs, such as NO. At the same time power connected to the GPRS-T3 security devices can be carried out through the AUX output of the module. The presence of the tamper wire entry allows for anti-tampering function, or program the alarm system GSM MICRA on another type of reaction.

And as an indicator of a problem connecting to the GSM network is a low-current output OC, which can also be used to indicate arm / disarm the system. MICRA modules will be installed only in enclosed areas with normal humidity, away from direct access by unauthorized persons and electrical appliances, which can cause interference with the functioning of the device. Also, when installing the module, you must consider that the thick walls and metal structures, "choke" the radio signal, so before you install the radio channel devices, for example, wireless alarms, security systems that use GSM, it is recommended use a special tester. To power the module requires a source of 220 VAC, but in case of power failure GPRS-T3 MICRA can use a battery backup power. Programming module can be perform locally with a PC using software GPRS-Soft, which is included in the package. For this module to be connected to COM-port using a special cable (part number DB9FC/RJ-KPL). Also, security of the GSM system can be programmed via GPRS-channel after entering the pre-prescribed in the module password.

In addition, the use of GPRS-technology allows you to transfer the event codes in the alarm system at the remote central monitoring STAM-2, or to convert SMET-256.

Design Machines

There are positional contour, combined and multi-cycle management. The design features. CNC machines have advanced technological capabilities of maintaining high feast nadezhnostin work. The design of CNC machine tools should tend to combine different types of obespeichivat processing (turning, milling, milling, grinding), easy loading blanks, unloading of parts (which is especially important when using industrial robots), automatic and remote upravleniesmenoy instrumental, etc. Povysheine precision machining is achieved by high precision and rigidity of the machine izgotovleinya exceeding the usual rigidity of the machine of the same destination, which produce a reduction in the length of its kinematic chains: primeniyayut pirvody autonomous, possibly reducing the number of mechanical gear drives of CNC machines must also provide a high bysrodeystvie. Increased accuracy helps eliminate gaps in the transmission gear drives innings snizheine friction losses in the guides and other mehainzmah, povysheine vibration resistance, thermal snizheine strain, with changes in machine sensors feedback. For umensheinya thermal deformation is necessary to ensure uniform temperature in rezim mehanzmah machine, which, for example, promotes preheating machine and its hydraulic system.

The temperature error of the machine can also be reduced by introducing a correction, a feed drive signals from temperature sensors. Basic components (frame, columns, bases) perform more zheestkimi by vvedeinya additional stiffeners. Guides CNC machines have a high wear resistance and low friction, thus reducing the Power steering servo drive, to increase the accuracy peremescheiny, reduce the mismatch in the tracking system. Pirvody and transducers for CNC machines. In connection with the development of microprocessor technology used for converters feed drives and main dvizheinya fully microprocessor-upravleinem digital converters and digital drives. Digital drives are electric motors operating at constant or alternating current.

Structurally, inverters, servo drives and the device main start and reverse yavlyayutsya individual electronic units upravleinya. Spindles CNC perform precise, rigid, with increased wear resistance of the necks, and posadochnyz based surfaces. The design of the spindle uslozhnyaetsyaiz much of it built in ustroystvavtomaticheskogo clenched and clamping tools, sensors for adaptive management and automated diagnostics. Supporting mehainzmy NC include tool changer, cleaning chips, lubrication system, clamping prisposobleinya, feeders, etc. This group mehainzmov CNC machines is significantly different from those mechanisms used in other universal machines. For example, the povysheinya productivity of CNC machines has been a sharp trailing uvelicheine of chips per unit time, hence creating vozinkla enobhodimost special devices for removal of chips. For time lost sokrascheinya feast downloads pisposobleniya used, allowing both set piece and take part during the processing of another piece. ( Tool change (shops, avtooperetory, turrets) should ensure the minimum time required to change tools, high reliability, stability polozheinya tool, ie, size constancy departing polozheine axis with repeated changes of the tool, have the necessary capacity of the store or turret. Turret is the most simple tool changer: installation and tool clamping is done manually. In the working position of one of the spindle is rotated by the main drive of the machine. Turrets mounted on lathes, drilling machines, milling machines, multi-purpose CNC machines, fixed in the head from 4 to 12 instruments.

Market Fiber

The broad scope defines a wide range of mineral products, manufactured by leading manufacturers, which include: – thermal insulation panels for metal, brick and concrete building components. Typically, they are pressed into between corresponding elements of design – mats for insulation and roof of underground structures. These products must be protected from moisture by installing a vapor barrier with a 'warm' side – special wind-slab, which is recommended as the windscreen of the soft slabs of wall and roof constructions. Especially for the 'ventilated' facades are designed ready-layer insulation plates with layers of different densities. They are placed so that part was more dense on the outside (from the ventilation gap), and less dense – was attached to the wall (bottom). – Semi-rigid plate, withstand the mechanical loads up to 5 kN/m2.

These boards are used, such as sandwich panels of reinforced concrete (type design 'sandwich'). Often, these boards have special grooves to drain condensate. This is especially important where the device is not possible to vent the air gap. For example, in the same concrete sandwich panels, the more so that the outer cladding has a low water vapor permeability. – Rigid plates, withstand up to 12 kN/m2 – boards increased rigidity, designed for flat roof insulation and are the basis for the roll roofing and mastic. There are special plates that, when used in As the top layer (with a two-layer insulation of the roof) attached to the roof of the desired grade. Glass Glass wool – a material that is the fiber that the technology preparation and properties have much in common with mineral wool.

To obtain a glass fiber using the same raw materials, and for the production of ordinary glass or waste glass industry. By the properties of wool is slightly different from the rock and slag wool. The differences are due, in part by the fact that the fibers of glass wool has a greater thickness (16-20 microns) and 2-3 times greater length. Due to this glass wool products have a high elasticity and durability. Glass-wool practically uniform and resistant to vibration. Thermal conductivity in the range 0,030-0,052 W / m K. Temperature resistance of conventional glass wool – +450 C, which is significantly lower than that of mineral wool. Thermal insulation materials made of fiberglass – good sound proofers, as they have a fibrous structure and absorb sound well. Have a high chemical resistance, do not contain corrosive agents, not hygroscopic. In the antiseptic treatment and lack of odor prevents the emergence of pests and mold in structures. This non-flammable material does not emit toxic and hazardous substances under the influence of fire. Steklovatnye products are widely used for thermal insulation of building structures. Glass fiber – soft and flexible material. Its products can coat the rough surface, as well as use in structures of any shape and configuration. At the same insulation products of glass are different forms of stability, can withstand aging without undergoing deformation. Fields of application are almost the same as for production of mineral wool. Nomenclature of thermal insulation products with glass wool includes: mats (soft board), sewed mats, semi-rigid plate on a synthetic bond, plates with high stiffness, to withstand considerable loads. Rigid plates, lined steklovoylokom are a good windscreen. On the long side panels can be connected together in a tongue and groove, which provides secure attachment and no gaps. More information about the situation in the market of glass wool and you can see in the report of the Academy of IKAR industrial markets' Market Fiber insulation in Russia. "

Serial Production

Serial production type is characterized by constant release of quite a large range of products. It determines the method of the party organization of production, when run in production parts or assemblies by the parties of a certain size at a certain steady succession of them over time. This allows you to organize the rhythmic output. In the mass production organization of labor has a more deep specialization than in the unit. Behind every workplace there is enshrined the execution of several specific details of operations. This will improve methods of processing, increases productivity.

Release of products series of relatively large quantities allows for considerable unification of the products and processes, produce normalized or standardized tnye details included in the design Series boloshmi parties, which reduces their costs. The relatively large size of the issue, the stability of the design, standardization of parts can be used along with a special universal high-performance equipment, automatic machines, special tools and supplies. Repeatability in output leads to economic viability for more elaborate process than in a single production. In the technical documentation shall be established modes of processing, equipment, special tooling and scientifically based technical standards of time. Becomes cost-effective to exclude the additional adjustment design by providing the dimensional stability of arriving at an assembly of parts.

This reduces the proportion of hand, especially finishing, works in overall complexity of manufacturing products. At the core manufacturing operations use specialized labor workers of average skill. In general, for batch type of production is characterized by less than individual, labor, materials consumption and cost of a single type of product, since there are higher levels of productivity. The output is organized by cyclically repeating the schedule, during operational and production planning schedules are developed and run production, set a strict order of sequence of products in the shops, sites and workplaces. Serial production of the most diverse (subdivided into three subtypes), and difficult. For batch type of production are all machine-tool company. In the small-and sredneseriynom production is used method of group technology. He especially effective in small-scale production. The essence of the group method is to develop a group process and manufacturing equipment group. For this purpose, all items are grouped on the basis of a constructive and technological similarities, required the same type of process equipment and tooling. From each group stands out the most complicated parts with the rest of the details inherent in the design and technological elements. If the group can not distinguish such detail, it is projected on the basis of existing integrated complex piece, which is designed for tooling, equipment is chosen. Group technology and operations sequence designed with the expectation that they provide any details of the fabrication of the group. If for some specific details of manufacturing operations provided by group technology, are not required, they are on the move production are ignored.

Choosing Ceiling Paint

Today I will Tell you how to choose a quality paint, as well as share the secrets of a perfect painting. Coating paint today is the most common type of finish and interior external surfaces. However, the choice of paint products do not just because you need to take into account the huge amount of detaley.Na site you can find detailed information on choosing materials for building and construction technology. Wear resistance is mainly dependent on vlagostoychivosti and strength forming a film. On the gloss directly affected species and the number of … Before you start painting the ceiling should be carefully prepare the surface, because of it, for the most chastti will depend upon how well she will paint. The ceiling should be as smooth, clean (do not have on its surface dirt and dust), it is desirable if it is already primed. If you want to achieve from the ceiling, as they say, ‘ideal belezny’, you will have to sweat heavily.

Mazaichnaya paint (granite paint) – it’s acrylic bubbles in the water-based, free of granite dust. Bubbles spray breaking on the wall, forming on the surface of the bitmap (texture of granite). Applied to the prepared primed surface – it could be a finishing putty, wood paneling, concrete, gypsum fiber board, gypsum, particleboard, plywood, metal and glass. You can paint the walls or acrylic or latex, which contain biocides. Such paints can counteract the formation of mold and mildew on the wall. But remember that the paint for your health. What graski can prevent mold and mildew? The fact that mold and fungi that are toxic … The decor House paint is important wins back wheel, as it not only adds aesthetic appearance of a surface, but also protects them from exposure to various external faktorrov thus prodlivaya his life. Each Paint consists of three main components: a carrier, binder and pigment. Thanks to the media paint turns fluid and smooth when applied.
