To choose the right power, you need to know in what conditions you plan to exploit it. First of all, you must define the necessary power plant, the type of engine and noise insulation. Thus, plants differ in the level of power. To understand what a plant needs for you, you should consider the planned power consumption. In this case, the calculations must be borne in mind that your power plant can not operate at maximum capacity, it must have headroom of at least 30%.
For questioning will be enough power capacity to two kilowatts. You will be able to safely operate fridge, use the room lights and watch tv. To provide electricity to the cottage will need power, power which is still ten times more. Another important type of power – kind of engine. Specialists are two types of power plants: and petrol station. Gasoline is best if you plan to use it only occasionally.
However, if power you need for regular use, then better opt for . Of course diesel power is more expensive, but it is cheaper to operate. So with a view of the engine determined. Come on. also come in different forms: High-speed and low speed. And here, again guided by the principles referred to above. If the station you need as an emergency power source, take high speed. It is noisy, but the cheaper low-speed power plant. But if you exploit it constantly, you have pity on his ears. If you're not using it at the cottage, and in the full residential settlement, without guard can not operate the power plant. For the purchase of housing can be ignored only if you operate the plant in open space (on the suburban building site, etc.).
Most people have an idea of the lifts elevators, but difficult to imagine what the lifts and on what grounds they can be distinguished. Lifting equipment, which will be discussed, at present receives the increasing popularity. And although it is called economy-class equipment, it is very reliable, easy to use and maintenance of hoisting equipment. By all the usual terminology lifting devices offered by us, can be divided and described as follows: Cargo lifts Lifts small freight elevators personal special lifts, in turn, hoists can be divided into mining lifts, cantilever lifts and inclined elevators. The cargo lifts, as well as a small freight elevator, can be attributed, and service lifts for restaurants, cafes, hotels, cultural and entertainment centers, etc. Small freight elevator capacity up to 250 kg of coal mine enforcement in particular are attractive because they do not require registration in the rtn, as well as all the above platforms. Personal lift is essentially a lift for a country house (cottage), you can call it cottage lift, but it is sometimes called a lift home or flats. Made a personal lift only an individual project based on technical specifications of the owner and is intended for personal use. Special podemnikipo rope suspension system, linking stand-platform, device drive protective fencing and other features are fundamentally different from existing versions of execution lifts.
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.
There are four main methods of disinfection: mechanical, physical, chemical and combined, combining two or three of these methods. Mechanical method of disinfection is to remove and destroy contaminated sites, the physical – in the disinfection by heat treatment, ultraviolet, or other similar methods. Chemical method used most extensively and involves the destruction of toxins and pathogenic bacteria using a disinfectant. Disinfectant for use in each case is chosen depending on the subject of cleaning and the composition of the funds. Main types disinfectants, based on major active components: inorganic, organic, biologically active.
Inorganic disinfectant – a tool which is based on acid alkalis, phosphates or silicates. In organic media used surface-active agent (surfactant), alcohol and other components. By biologically active funds are based on aldehydes, peroxides and other substances similar action. Disinfectant must meet the following requirements: highly soluble in water and be active even in small concentrations, have a fairly wide range and high speed action, low level of toxicity. Another quality that must have a modern disinfectant – No adverse impact on the object of cleaning (surface damage, discoloration, etc.). From the point of convenience and efficiency of use, disinfectant should be safe and convenient for transportation and storage, and still have not overcharge and concentration, permitting its use in small doses. As mentioned above, the disinfectant should be well soluble in water. Fluid rapid effect on bacteria, effectively destroys pollution and they contain dangerous toxic substances.
So are achieved and requirements to speed preparations. Therefore, the disinfectants are produced, usually in liquid or powdered form, which allows you to quickly dissolve them in water. Some liquid disinfectants do not form a foam, so the processing of multiple objects is accelerated. Foam disinfectants have a number of other benefits. Due to saturation of water and air foam quickly penetrate the contaminated layer, the longer it is delayed, and thus facilitates the disinfection process and increases its effectiveness.
