One of the main purpose of the alarm is determining whether an invasion of protected areas and the activation of various warning devices (siren, strobe flash), or alert the owner and item centralized monitoring or protection (private security company or other security). One of the most common types of alarm is the GSM-guard. Continue to learn more with: John H. Wood Jr.. When using the gsm signaling controlled territory set all the necessary sensors and a gsm module. Furthermore, all devices are connected to the control (control) panel. When firing any of the sensors activated the gsm module, which sends alarm sms messages or make calls to cell phone owner.
Also, when you need gsm system can be fitted with a special voice device to send messages to the programmed telephone numbers. Arming and disarming alarm systems with security is using a special remote control or keyboard that came with the system. Note that the security systems of gsm is currently very popular and has long enjoyed worldwide success. After all, gsm alarm systems – is one of the most affordable and effective manual way to protect your apartments, villas or cottages, small office or shop, warehouse, compartment, Trade Center garage, the car from breaking and entering "uninvited guests". Modern gsm alarm system does not require wiring, because it is equipped with wireless sensors that alert you to call or sms message. Among the advantages of gsm alarm system for use in building security systems are the following: * Wireless high-sensitivity sensors provide high protection of the protected area or room * wireless connection does not violate the interior of the protected premises; * reliability, ease of setup and operation; * The existence of a special radio-alarm buttons * the capabilities to empowerment of the gsm signaling * The possibility of virtually unlimited number of radiodatchikov * autonomous power system security; * possibility of synchronous operation with other alarm detectors, sensitive to moisture, smoke, heat, gas and so on * technical support to user * remote access management system gsm alarm system * Remote control security system via sms, mms or via audio using dtmf signals; * The possibility of the equipment with connection to other phone numbers * inverse voice * Sound notifications; The complete set of standard models of gsm systems alarm consists of wireless motion sensors and door opening, siren, wireless key fobs for the removal and installation of protected system.
The main task and the main reason for which were set up carts – it is the movement of goods in different weights for short distances. This may be to move within the plant, factory, yard area and so on. And the main load for this rests on an essential element of a cart – the wheel. For more specific information, check out Professor of Internet Governance. The wheel can be considered as an element of taking over the entire load. So it is when you consider that the load pushes onto the platform truck, and she in turn at the wheel. This means that the selection of wheels should be made taking into account the weight of the load and weight of the truck. If we look closely at the table of technical parameters of platform trucks, we see that the load platform Truck is in the range from 200 to 900 pounds. Itself truck can weigh in the range of 14.7 to 65.6 kg, and from this it is easy to understand that the stated load capacity ultimately rests on the wheels themselves. Ray Kurzweil is full of insight into the issues.
On the platform truck pose two types of wheels. First – wheel and tire from cast rubber, the second – the wheels with pneumatic tires. For each wheel or wheel bearings have enough accessories to complement functionally the wheel. The most common – A brake system and wheels with tires from a gray non marking rubber floor. The latter are used when necessary to keep the floor clean after passing on him a loaded truck.
Wheel of black rubber with turn or turn truck on the site can leave trudnostiraemye footprints on the floor. Tire wheel of a gray rubber exclude such an accident. Of course the fact that the tire has a different color does not mean that it is made of another less strong or less-quality rubber, which means it does not affect the specifications and load wheels. Wheel bearings (or rollers) are located on the platform carts on the corners platform, to be exact as close as possible to its corners. Brackets castors attached to the bars below. Such an arrangement provides a stable support stability, and thus maximizes all of the cargo area of the platform. It is also a positive impact on the maneuverability and controllability .V standard truck includes two swivel and two fixed castors same height, while turning set by the handles, and it makes it much easier to manage truck. The greatest agility equipment provides four swivel wheels. In this case, the ground force is applied to rotate the push cart on the rear-wheel drive, located on the handle and the front wheels are the thrusters. Truck with a complete set requires some management skills, especially if heavy goods are transported at a sufficient speed to a rotation of inertia truck had become unmanageable. The most common example of such a truck – a food cart in a supermarket. Try to take her empty at low speed – it's easy and quite convenient. But if it is filled with food, even if the average speed after a sharp turn in time to align the cart is difficult. The reason for this is just a weight and all the castors swivel. Features castors or rollers, mounted on truck platform may be very different. They depend on various areas and purposes of the application and may be selected individually. In the future we will return to this subject and consider the region industries where applicable wheels and bearings are installed on platform trucks.
There are various types of compressors (screw compressors, reciprocating compressors, etc.) used in the technique as a source of compressed air. In compressors of this type of compressed air in a confined space cylinder by the reciprocating motion of the piston. Structurally, they represent a unit that includes a compressor head, the electric drive, a receiver and an automatic pressure control (Pressure switch). The popularity of reciprocating compressors is determined by their low cost, acceptable weight and size parameters, simplicity of operation and maintenance and output characteristics, capable of meet the needs of virtually any enterprise. The main characteristics of the compressor are two parameters – the maximum pressure (Pmax) and volumetric productivity or supply (Q).
Most of the proposed compressors on the market today are developing a pressure requirements of standard pneumatic equipment and tools. The market offers compressors with a maximum pressure of 6, 8, 10, 16 bar. Recall that the nominal operating pressure paint guns – 3.4 bar, pneumatic tools – up to 6,5 bar. An exception is the pneumatic tire changers, for which many manufacturers recommend using compressed air at a pressure of 8.10 bar. However, Practice shows that the pneumatic tire changer equipment works reliably, and using 8-bar compressor. What else do you need to consider to determine the maximum pressure developed by the compressor? Firstly, should be borne in mind that the automatic pressure regulation of all compressors configured in such a way that maintains the pressure in the receiver with a tolerance of -2 bar, the maximum value. This means that in during compressor operation with Pmax-8 bar outlet pressure can range from 6 to 8 bar, 10-bar, – respectively, from 8 to 10 bar. Factory adjustment pressure switch can be modified only in the direction reduce the minimum pressure.
Secondly, be aware that the presence of extended pnevmomagistraley to consumers of compressed air causes a pressure drop in the line. When errors in the design of pneumatic (Use small-diameter tubes, using water shut-off devices, irrational laying roads, etc.), it can reach a significant magnitude and cause poor performance pneumatic equipment. To avoid possible trouble in such cases, should be preferred to the compressor with a higher maximum pressure. Some margin pressure is useful from another point of view. The higher pressure developed by the compressor, the greater mass of air it can pump into the receiver, and the longer the time the latter will be emptied to the minimum allowable pressure, allowing the compressor time to rest. By the way, about the rest: but if he needs an iron compressor? In response to this question lies the key to understanding the features of the workflow in the piston compressor. Considering it, determines the most important characteristic of the compressor – performance.
Truck platform is the most simple and powerful way to move goods. It is not very whimsical in service and can easily move through any type of flooring. Truck platform may reliably operate at any temperature in any climate. Truck platform, despite the seeming simplicity of design, have their own characteristics. So truck with a special anti-rough coating used for freight transportation over uneven surfaces, and platform trucks with high sides, allow to carry not only the overall piece goods, but also a lot of small goods in bulk and weight goods. Truck platform has capacity of 150 to 750 kg, more often – 300-400 kg. Truck platform are solid or lattice.
Truck Lattice platform characterized by a relatively small weight. Solid truck with a metal or plastic platform can withstand the heaviest loads. The solid platform can be decking materials such as plywood, rubber, metal or rubber-covered metal preventing slip cargo. Truck platform differ in the type of platform, and design. Platform hand truck with a solid platform suitable for the carriage of any cargo, and lightweight hand truck platform c-lattice convenient for carriage of bulk cargo. Such warehouse truck platform – the best solution for the transport crates and boxes. Storage platform truck with boards suitable for carriage of bags or small boxes. A shopping cart for storage can be either solid or lattice.
The cargo is placed on a platform truck and moved with the pulling power of man, administering it by the handle mounted on the platform. Jacklift platform is defined by two parameters. The first load of the platform, which depends on the diameter and thickness of metal pipes used in the manufacture of a skeleton platform truck. And second, on-duty castors mounted on the platform truck. There are special types of trucks platform, the application of which only a specified operating conditions. Platform truck with borders are applicable for the transport of small bulky cargo, that cargo is not spilled during transport. Truck as the shelves of several nearby applicable, for example, in medicine, or in technical areas, where it is necessary to carry a lot of small things or tools.
The present community and industrial production will not be able to imagine without the use of metal. Made of metal construction and are utilized in everyday life, and in virtually any desired manufacturing process, and construction of buildings and vehicles. Considerable use of metal structures leads to the need for regular adjustment of the addition and different spheres of metal. Say, all the while having the latest additives, which allow a variety of metal compounds is much more robust, long-life and thus resistant to various types of influences, too – and a kind of corrosion. In order to work with the metal proved to be the most practical, currently applies the most sophisticated welding equipment, allowing to make high-precision welding. In this equipment provides a chance perform a variety of options for welding – from manual welding to welding machines designed for ac and devices produced by the plasma cutting.
In this present-day technologies provide opportunity to engage the welding procedures, including in an atmosphere filled with active or inert gases. In this case, are utilized welding semi-automatic device. However, there are many other development, providing an opportunity to achieve the highest quality metal, and in addition to control the quality factor of the resulting object. Computer technologies provide the ability to enjoy the really felt the quality of products. Must also say that the modern welding equipment, and more, and other specific equipment for metal processing to date can be chosen as the sellers who provide a line of products from different manufacturers most of the large number of countries around the world, to the same extent and with local manufacturers, offering a wide range of equipment of the highest quality standards in the most various segments.
In a medium equipment for metal production overseas to date the highest prevalence may use product line companies in China. Low cost explains the popularity of this product line. In the top segment is rastsenochnom Western manufacturers, as for the best combination of cost and reliability options, then really be noted that such options is the welding equipment of the Russian edition. A strong scientific basis for a chance to get good make equipment at affordable rates.
The density of wood of different species is different. Therefore, 1 ton of coal can be obtained from 7.8 cubic meters of birch and only 12.11 cubic meters of softwood species. Manufacturing technology of charcoal: In a special oven is loaded and burnt birch logs. After the initial burning of wood in the stove stop the flow of oxygen. process of carbonization (pyrolysis). After cooling, the birch charcoal is taken out, sieved and packaged.
Excellent charcoal is ready. The technology of charcoal production is relatively simple, but still requires a certain organizational culture. Otherwise, the output of coal is reduced, it can be obtained at lower quality. Currently, there are many devices for charcoal burning. At the current stage of development are most appropriate technological solutions that can be used in a forestry company and can recycle waste. In this devices must meet the following conditions: the performance of raw material should correspond to the volume of waste at the plant (typically 3000-20000 m per year). So way preclude further transport of raw materials, increases the cost of production; for a small performance impractical to process liquid products. They should be burned, covering the need for process heat; installation should be clean.
Necessary to eliminate environmental emissions and pollution; Installation should be simple to manufacture. Transportable option should be able to move in relocation of timber; Installation should be easy to manage, explosion and fire. As for guests charcoal operates in Russia gost 7657-84 and gost 7657-94 'Charcoal grades A, B, B'.
Products with high turnover, as well as large and heavy items should be placed closer to the exit site and picking orders. And vice versa – the goods are rarely received the warehouse must be kept away from the entrance and exit the storage area. The same applies to the seasonal storage of goods, long stored in the warehouse. Products with a strong odor can not be stored next to the goods perceiving odors, and hygroscopic (readily absorbing moisture) – with the goods, which have large amounts of moisture. Isolated store combustible and flammable products. To expedite work on placement of products in storage locations when entering the warehouse and to facilitate their search for the follow-picking each storage location is assigned its own code.
Digital or alpha-numeric designation is applied paint on the shelves of the cell. In addition, each rack mounted plate with its number and symbol of stored goods. Layout of racks showing codes are posted in the storage area in a conspicuous place. Regardless of method of storing the goods they are laid out marking, which also simplifies the process of picking goods. information. As already noted, in addition to rational distribution of products in stock to create the optimum conditions for their storage. For this purpose, should continuously monitor the temperature and humidity of indoor storage and keep them at the level established standards and sanitary regulations for individual product groups. And, do not put their sharp differences. Monitoring of air temperatures is carried out using a thermometer or a block of universal remote monitoring systems, of portable devices, with that within 3-4 minutes can determine the temperature at various points in the repository.
When conducting pre-commissioning work at the brick mini-mills, a number of communication problems. As part of the equipment for brick contains several pieces of equipment: presses, conveyors, bucket elevators, silos of cement and inert fillers, mixers, dispensers aggregates, cement, pigments and water. All of this equipment can be manufactured at various companies in Russia and is not consistent in their performance. To synchronize the work of all the mechanisms necessary to have appropriate control cabinet mini brick factory. Control cabinets are made on the basis of modern microprocessor and electronic technology and allow you to control equipment in manual and automatic modes. 'Automatic' – this is the main mode, which is the output. It is automatic synchronization of all the mechanisms mini brick plant productivity. The presence of modes of 'Hand' and 'Debug' allows you to check the work of all units of equipment brick factory mini step by step.
The main system parameters Control can be set manually with the built-in keyboard and displayed on a digital display cabinet. Finding the equipment at a certain stage of the program set is denoted by light indication. With the passage of malfunctioning equipment, the program automatically stops the equipment and displayed an error code. It only remains to determine the cause of failure. In the control cabinet instead of the widely used standard contactors and starters using electronic switching elements.
This allowed us to significantly increase the reliability and robustness of the control cabinet, as well as the warranty period of uptime and overall life. Currently produced works on manufacturing of control cabinets mini brick factories on the basis of SCADA-systems. Application of this system will change the architecture of a mini factory automation, process set parameters and control equipment, as well as visualization of information. Processing of information coming from all the arrangements made in real time. Exchange of data between industrial controllers and I / O devices are also in real time via the drivers. Displaying all necessary information on the screen represented in human-readable form. Appears opportunity to prepare and report on the progress of the process. All mentioned above – there are certain advantages of modern technology, which allows a control system in a distributed control system mini brick factories.
Noise at work does not exceed the general background noise of the equipment (pump group). Often the work umpeu be judged only by reading. This effect was achieved thanks to the quality of mixing steam and water in umpeu and applying pressure pulsation dampener heated flow, because principle of anti-vibration is simple – the better the blended environment, the less vibration and noise. Since the principle of umpeu does not imply the existence of cavitation processes in their work, they do not have cavitation erosion, which leads to their high durability (pilot installation worked without repair 8 years). Therefore, the manufacturer umpeu made using carbon and alloy steels (St20, St09G2S of seamless tubes and forged parts piping), which reduces manufacturing costs and provides high maintainability umpeu. Start-up. Run psa – means to create such conditions, when the given parameters of steam and water at the entrance by the calculated flow regime flow in the nozzle and the main thing – to jump seal was placed in the mixing chamber or the diffuser. The main obstacle to starting a psa is the inability to pass through it in the startup period the entire volume of the mixture, since by virtue of the transitional process, it is not have the necessary speed and density. Apply the following ways to run the PSA: by changing the start time on the input parameters of flows of steam and water (steam pressure, water pressure, temperature, steam, water temperature, steam dryness) or by removing part of the flow from the mixing chamber along its length, or by changing the geometry at the start time of psa (change in area of the mixing chamber) 2.
