Materials

At the same time he took power terminals. In the optimality of its solutions can be no doubt – otherwise the project simply will not work . Brand and manufacturer here is not as important as production and quality of the product regulated fairly strictly, properly selected size cable or wire to ensure the normal functioning of the system. However, there are certain subtleties. For example, choosing cable for field wiring costs pay attention to the color of isolation and cross-sectional configuration.

Also, the customer must determine the type of wiring. It can be hidden and open. Pluses flush – no wires and terminals devices 'disguise' storage space. This simplifies the arrangement of furniture and reduces the risk of damaging the cables. Moreover, in most interiors concealed wiring will be more appropriate. But also in the medal has a reverse side. Concealed wiring labor intensive (you need shtroblenie walls and their subsequent terminations), and in some cases more expensive than open. However, these problems, albeit with a cost, but solvable.

The main disadvantage of hidden Wiring – its low mobility. Error in choosing the location of wiring products may cause inconvenience the operation of that device or the need for a new cycle of work-related implementation of 'drill-' operations. Open wire, in contrast, are mobile enough: most of the work boils down to the laying of conductors and their fixation on the bearing surfaces. The exception is the Wall and floor slabs. Among the other advantages of an open wire mention ease of maintenance and condition monitoring, and troubleshooting. On the cons we have already casually mentioned – she 'eats up' part living space, in addition, arranged open conductors and devices can be easily damaged. There are, however, products that reduce the chance: electrical skirting boards, trunking, plastic pipes and similar protective covers. However, they still occupy some of the living space, also can be used not in every interior. epilogue So, at the hands of a customer has a power project, which maximum corresponds to his wishes as to the architecture of cable networks and on the materials incorporated in the specification. Already signed a contract with the contracting organization, which has a license to perform installation works, in short, experts are beginning to translate dreams into reality. It was then the owner of the cottage and there comes the most hectic time. Unfortunately, in the assembly work is a loophole – if insufficient control the temptation to save either materials or labor input for too long. You can, for example, be used to flush the cable of the same brand but with a smaller section. Such a 'marriage' is usually revealed too late. That is why the installation works best to attract an organization with a good reputation. If a credible contractor can not be found, consider the copyright supervision of the system designers. However, personal control also does not hurt. Very important to avoid twisting the cables, especially aluminum and copper conductors. For connection of conductors used a wide range of terminals and terminal strips. Switching places must be located within the protective boxes – this will monitor the status of contact and ihot external influences. Remember, most of the problems associated with places of cable networks, which are inaccessible for inspection.

Hydraulic Cylinders

Hydraulic cylinders are an integral part of modern industrial equipment All work of this movement of bulky equipment such as earthmoving and road vehicles, should be implemented with a high degree of accuracy and dynamics, especially in e-governance. Working motion hydraulic excavator carried out by means of hydraulic cylinders. Arrow up of two hydraulic cylinders. Handle and shovel move a hydraulic cylinder. Depending on the size of the machine design pressure in the hydraulic cylinders up to 160 320 bar. During operation, when static loads are added to the dynamic load (sudden changes in direction traffic load during loading and unloading of the bucket and other), individual pressure peaks can be several times higher than the calculated values.

In these circumstances, hydraulic cylinder design work, and especially the quality of its production is very important. Welds head and cylinder base with a cylindrical housing demand from the applied welding process is very high quality and reliable welding. In most cases, the annular sutures are in the section of U – shaped profile. Centering surface, made boring, so that the exact form of landing and serve as substrates root welds. Because housing is machined (with a tolerance H8), providing direction of movement of the piston, then the root joint requires a minimum of penetration (depending on the design – 1.5 3 mm). During welding, the spigot has melted, leaving a clean surface treated boring. For welding use various methods to ensure the implementation of the above requirements with high performance.
