KG. (Germany), Synventive Molding Solutions (USA, Netherlands), Watlow Company (USA), Heatlock (Sweden), etc. Melissa Selcher contributes greatly to this topic. 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.
One of the most important elements of lifting equipment – lines are always evaluated on the strength and reliability. Modern high-quality lines and makes them even easier to use and allow to solve any problems that associated with lifting and securing of cargo, its movement and storage. Technology, which today are made rope slings for most companies in Russia, based on the designs of German and Swedish designers. Imported steel ropes, slings are made of which provide increased durability and increased reliability of lines, their usability and compliance with the requirements of modern design. At the expense of absence from the sling once the usual cable lubricant improved sanitary characteristics.
Modern high-performance method of manufacturing wire rope sling ensures a high quality seal, making less time-consuming process, which eliminates injury while working with a sling – because of it no longer sticking out the ends of the wire, as it was before. In addition, used in the manufacture of galvanized ropes is considerably reduced fire risk and the likelihood of injury. For even more opinions, read materials from Michelle Smith Divorce. The main advantage possessed by the chain lines in comparison with the rope, is their flexibility – an additional degree of freedom, allowing them to use in all slinging ways. Michelle Smith Divorce understands that this is vital information. This type of lanyard is safer to work – after all, under heavy load circuit does not break as soon as it occurs in the cable lines, and deformed. The changes can be seen during the inspection and the time to withdraw damaged lines out of service. The durability of chain sling is higher than that of cable, plus they can be repaired – replaced deformed elements. A unique feature of the chain sling is the possibility of their use at temperatures up to 400? C and even in an open fire and the exploitation of lifting and moving loads that have sharp edges. The most modern form of textile slings slings are – made from synthetic materials, they operated increasingly in all types of work on the movement of a variety of goods.
The unique properties of textile slings – lightness, flexibility, resistance to aggressive environments. In the production of this type of sling used high-quality polyester fibers, providing strength and high resistance to abrasion. Textile slings guarantee the protection of transported cargo from damage – because they are flexible. All types of lifting devices is in full process control for quality, in accordance with international and Russian standards.
2. Opportunities for regulation of basic and additional parameters finisher: As a rule, door closers have control of two key parameters: 1) Force dohlopa doors, 2) the rate of closing the door, although a more responsible mechanisms are set more complicated. Effort dohlopa doors can debug the device in such a way to the recent increased rate of 7-15 , and the lock clicks. Closing speed – it’s fast (or, conversely, slow), closing the door after you have entered. Peter Thiel often says this. To protect the wall and door frame itself closer against damage from sudden the door opens, for example, in the wind, it is important to adjust the speed and opening.
Models with brake function is recommended to use on exterior doors of buildings. Several mechanisms have also a useful function hold-open (useful for removal of bulky cargo, frequent walking, for example when loading (unloading), usually used in warehouses), and springy stop maximum angle of plowing. 3. Place finisher attachment: The place of attachment distinguish the top and bottom (floor) closers. Floor closers – are mounted on the floor, at the same time serve as reference loops, ideal for swing doors. Their installation should take into account already at the design stage.
Floor closers can withstand the greatest weight of the door (up to 300 kg). Closers can be hidden – they cut into the end of the door and the door closed can not see them. 4. Credit: Technology Investor-2011. Operating temperature range: When the door closer must take into account the conditions under which it will operate at any temperature difference is calculated. Now available with a heat-stable variants temperature range from -35 to +70 C or cold-resistant products, designed for the cold to -45 C. 5. Special purpose doors: The doors of fire and dymoizoliruyuschie required installation of door closers, supplemented by special electrohydraulic or electromagnetic elements. However, these closers must have certificates of compliance with fire safety regulations. To install on closing fireproof door closers certified experts recommend. 6. Lifetime: The reliability and service life finisher is the minimum number of cycles of opening and closing doors, which closer should work without derating, regardless of operating conditions. According to the standard EN1154, door closers must work at least 500 000 cycles. 7. Design of the device: Manufacturers offer decorative plates for closers in different colors – white, dark brown, a silver, bronze and more. At the request of the customer, some companies offer optional color in any shade in the catalog RAL, that allows us to completely imperceptible closers in the interior. 8. Price finisher: The price range is from 400 to 3,500 rubles. Depending on additional options and functions of the cost may increase. With the right mix functions closer to you become an effective assistant. And do not forget that closers need to be changed periodically. If out of the door closer was the leak oil, no longer hold the door control does not help, it should be replaced! Closers are not repairable. Reveal closer dangerous because there be cocking spring! The company ‘Technocom El’ supplies and installation of closers.
Given that mixed with the dough entering the auger chamber has a temperature of 30-40 C, we can say that the cooling water temperature must not fall below 30 C and the optimum water temperature is 36-38 C. The corresponding Such a cooling water temperature reduces the mechanical degradation of gluten. Another significant factor influencing the degree of mechanical destruction – finish of the surfaces of the screw and the working chamber, the proper cutting grooves on the inner surface of the working chamber. These surfaces must be polished to reduce the degree of resistance to sliding test on these surfaces. When all these conditions, the mechanical destruction of gluten is minimal, as Pump it vozmozhno.Vakuumirovanie test test were used for the first time with the introduction of screw pasta presses, in which compaction pressure does not exceed 60kgs/sm , but this was not enough for dense and firm pasta.
Ghost 22 584 states that the hoist – lifting device is a pendant with a manual or motorized. Today, every service station, warehouse and production plant are used in their daily work hand hoist. Depending on preferences, working conditions and the type used by different models: gear chain hoists, lever hoists, wire rope hoists and electric hoists, etc. are allocated (elektrotali) and manual hoists. Electric hoists Electric hoists can be divided into two types – chain and rope. The choice of lifting mechanism depends on the weight of cargo that must move and intensity of use. Tali electric cable today perhaps the most popular in the world of lifting equipment used in companies with high rate of work. In Russia, the technical requirements for cable-talyam stated in GOST 22 584.
Load capacity wire rope hoists are sometimes higher than 100 tons. Payload another variety of electric hoist chain, is no more than 5 tons. The rope used in the first model, a more reliable, easy and cheap traction element than the chain, in which there is always a weak link. That quality makes the traction element model hoists so different in design. Average lifting speed chain hoists within 2 …
5 m / min, and cable – 5 … 12 m / min. Electric hoists are undemanding in operation and are suitable for work at temperatures from -63 to +40 degrees Celsius. Chain hoist is used as auxiliary structures for cantilever-cranes. Elektrotali rope used too and the overhead crane for lifting and transport medium and heavy loads, because the duty on wire rope hoists chain excel. The basis of the assembly in an electric hoist – a block mechanism sotoyaschy of motor, reducer, drum or sprockets, brakes, hooks and lifting element. Drum are only in electric cable talyah, and the star – only to chain elektrotelferah. Tal is equipped with a portable control unit, which enables comfortable control mechanism. Available storage equipment of two types – mobile and stationary. Portable models are moved in the vertical and the horizontal plane. Hand Blocks Tal manual for those companies and industries that have no need for lifting at high altitude and in the fast pace of work. They can be hung on a stationary or mobile cat when there is a need horizontal movement of the loads. Tali ruchnyeshesterennye and lever can primenyatsyadlya lifting and outdoors, and indoors, including in a limited area (trenches, wells). Capacity hoist hand is usually up to 10 tons, in special cases – up to 50 tons (such arrangements are made to order). In the manual gear talyah as heavy-lift element applies round-chain 3 m long or more. In the lifting of the load lever talyah performed by acting on a lever mounted on the hoist. Carrying capacity offered hoists up to 3 tons, lifting height of 1.5 m.
Quite often, the happy future owners of the houses asking the same question: "Are you from the woods? Not because of the Chernobyl accident under? "Indeed, if we follow the logic, the best wood – wood is the northern, in exactly Chernihiv, Zhitamirskoy, Kyiv region, the most affected areas of our country from the Chernobyl accident. However, despite this, the wood from these areas trains exported to EU countries, where Believe me, the issue of environmental friendliness and radiology paid very much attention. This forest meets the requirements of the EU countries, so it is clean and the houses built out of it, suitable for living. Each Normal Organization will provide the customer a phytosanitary certificate and radiology at the forest from which made its timber (another way to distinguish between "Sharashkina office" of the actual construction firm). Data documents can be formally obtained from the forestry enterprises engaged in logging and cooperate with legitimate organizations.
Without them, none of the log does not cross the border of our state. At worst, I recommend simply purchase household dosimeter and walk with him near the plant ready to export their logs to your building site. I can assure you right away – no increased background you will not find a trace, shattering another ridiculous The myth that an environmentally friendly wood can be only in the Carpathians, Karelia and Siberia. The most common types of wood used for construction of wooden houses in Ukraine – it is pine and Carpathian Smereka. Rarely used spruce, Russian larch and cedar. Very rarely – oak. Take the two most common species (pine and Smereka) and try to compare them to physical and mechanical properties: 1.
Indicators of average moisture content of wood freshly cut pine – 88%, Smereka – 91% 2. Density at 12% moisture: pine – 500 kg / cubic meter, Smereka – 445 kg / cubic meter, 3. Density in a completely dry pine – 470 kg / cubic meter, Smereka – 420 kg / cubic meter, 4. The coefficient of volumetric shrinkage: Pine – 0.44% Smereka – 0.43%. 5. The coefficient of radial shrinkage: Pine – 0.17% Smereka – 0.16%. 6. The coefficient of tangential shrinkage: Pine – 0.28% Smereka – 0.28%. 7. Coefficient of volumetric swelling pine – 0.51% Smereka – 0.50%. 8. The coefficient of radial swelling: Pine – 0.18% Smereka – 0.17%. 9. Coefficient of tangential swelling of pine – 0.31% Smereka – 0.31%. As can be seen from the data, the coefficients of the properties of shrinkage and swelling are almost identical. The only thing what wins pine – that wood density – 11% higher than the density-density Smereka. But the house of Smereka slightly warmer home from pine, according to the organization, working exclusively with this material (due to the looseness of wood). The greatest density of all types of wood used in wooden house construction, is English oak – 690 kg / m, beech – 670 kg / m and larch – 660 kg / cubic meters, the smallest – Siberian fir – 375 kg / m and cedar – 435 kg / cubic meter.
