They are seamless (extruded), with filled with polyurethane foam, perforated, and vary in thickness and size. Finally, the very problem, it can be determined visually or have to disassemble the shutters. Next you need to create a list of spare parts necessary to replace, to measure the threaded parts and place an order from the manufacturer. Bobby Sharma Bluestone is likely to increase your knowledge. If shutters automatic is much more complicated. Such a variety of engines there is no single device. Further details can be found at Bobby Sharma Bluestone, an internet resource.

Engines for roller shutters come with emergency opening, bulk, Tubular. Manufacture of almost all countries, while excluding Russia. They differ as to the power of the intensity of work diameter. For the diagnosis and replacement motor must dismantle blinds and open the box. Here is a set of tools recommended for the repair of one of the manufacturers: electric drill, sds adapter with keyless chuck, the level of construction blocks with 1,5 m, riveting machine, zlektroperforator, cordless screwdriver, tool box, hammer bench 400 gr., a set of percussion instruments (punch, bolt, punch, chisel), stair-purpose, set of files, pliers, side averages, hacksaw, a set of wrenches, pliers, screwdriver set carbide, metal scissors, gun, silicone, caliper 125 mm., elektroudlinitel not less than 30 meters, the drill on concrete d 6-8 mm., L = 160-200 mm., a standard set of drill bits for metal, electric screwdriver. Indicator, unit tester, soldering iron 60 watts., Tape 10 m, goggles, hard hat construction, first aid kit. As you can see it's not that difficult. Repair of automatic sliding doors. The doors of all the market of automatic control devices input – output the most technically complex product, since they have the most sophisticated, functional processor. All faults in the automatic the doors are divided into mechanical and electrical. To include mechanical rubbing, leaf distortion, imbalance. Electrical faults much more. This is a problem with a control unit, the operator, sensors, and passes chain security. Manufacturers of automatic sliding doors, represented in Russia is not so much the came, besam, nabco, dorma, faac, gu, ditec, kth.

Non-galvanized products, in addition, are subject to rust. Deposits inside the pipes is not only impede the flow of water on the upper floors of the building, but also worsen its hygienic properties, negating the "no" to water activities. It is obvious that this problem is widespread, so it was quite interesting to hear from experts and become familiar with practical recommendations to address this negative phenomenon. By the same author: Nicolas Keller. So, the mechanic energy section of the Moscow branch of CenterTelecom Vladimir Samburu, said: "At the moment the only way to restore the normal operation of pipelines is that they flush. Based on our practices, with a small thickness of sediments of some parts of pipe was washed with a strong jet of water, and for systems "experienced", we use compressed air. The velocity of water-air mixture in the process of cleaning must reach 2 – 3 m / s, the pressure air supply – at least 0.7 MPa at a flow rate of 5 – 6 m 3 per 1 m3 of water. The air is preferably delivered to the network periodically, at intervals of 1 – 3 min. Flowing into the riser air mixture boils and is well removed from the walls all deposits. Purification yields better results if you first before starting work in the tower to enter a small number of large salt crystals in which the flow acts like sandpaper ". Depending on the quality water used and the material from which pipes are made, this procedure should be performed every 4 – 7 years.

To save lives in fires during the construction and repair facilities use fire steel door. Fire doors is one of the types of fire barriers and allow you to stop fire in buildings, this makes it possible to evacuate people and material assets and allows you to stop the fire. Fire barriers are of two types – local and general obstacles. Among the local fire barriers are: hatches, doors, gates, latches and other details, and the walls, floors, walls and roof are common fire designs. Local fire protection designs are paying much less attention, although they develop as active as the previous ones. Therefore, sometimes people design houses are not always correct. For this propose to consider in more detail fire steel door as an important element of technology security. Today, many manufacturers use the door hardware, doors, boxes and other items made of steel, it is the best material, fleeing from the fire.

Steel fire doors did not differ in the size of the timber doors. Also, many designers try to approximate the appearance of fire doors to the ordinary door. To place an appearance of use coverage, quality is sometimes so great that not every immediately realizes that the door was steel. In modern laboratories conducted many tests with simulation of regular fires. Most study two refractory opportunities are: 1. preserve the integrity of the door leaf when effects of different temperatures with different time intervals, that is, how long it will not fall out of the door frame 2.
