When opening the tap water from the accumulator enters the network and compensates for the sharp drop in pressure. The larger tank capacity, the less often the pump. Sales can be found accumulators with capacity from eight to several hundreds and even thousands of liters. I must say that cheap vosmilitrovye tanks not adequately cope with their problems. Thus, the draw-point (kitchen faucet, shower, dishwasher, etc.) spends from six to fifteen liters per minute, so the only missing eight liters for 15-30 seconds of a particular device. Practice shows that the optimal solution for a country house is to buy 25 – or 50-liter accumulator (cost 50-100 USD). Important operating parameters of pumping stations are the compactness of the equipment and quiet of his work.

Good performance in complex series of mq (Grundfos): their overall size is just 57x22x32 cm This mini-station will fit even on the kitchen shelf. Quiet Operation depends primarily on the design of the pump (centrifugal pump is much quieter than the vortex) and the method of motor cooling (fan or air pumped liquid). Thus, the pump motor mq cooled by water, which provides a lower noise level. Nevertheless, the leaders are pumps 'glandless' (for example, a series of chie, Grundfos). Without water, appliances can overheat and fail, so safe work in such equipment used protection from 'dry run'. This option have a series jexm (Ebara), bgm (Lowara), ngc with the automation unit brio (Calpeda), station mq (Grundfos), mcx (Nocchi), Wilo-Jet fwj (WILO) and Hydrofresh (Pedrollo).

CCD Cameras

Now, as to the owners of cameras and before the master service departments are increasingly question the advisability of repairing a damaged camera.

The Constitution and the circuitry is quite complicated camera, even an experienced professional who has behind him not one hundred refurbished cameras haste in the work would only increase costs both time and money.

This is the intelligent use of available instruments, the necessary service documentation, effective organization of the order necessary components, the availability and timely completion of the warehouse workshop "driving" spare parts. Only in this case, we can provide a reasonable amount of camera repair for the owner, and accordingly the studio profit. Not superfluous here write that often spares repair cameras supplied how finished node ie lens assembly, not a separate component of the concept (IC, transistor, transformer, etc.), and the board as a whole. It is important to time, in the process of repair, to determine the need to replace the node, the possibility of his order, price and delivery time to inform the owner of the vehicle, to inform he final cost of repairs and, if his consent to continue. In case of failure mass content saved time, effort and money. Our shop provides repair photographic equipment. Material for our website is aimed primarily at owners of cameras. Here you can find detailed descriptions of common faults, many of which are accompanied by photographs. For example, fault in a digital camera, Sony DSC-F717 associated with failure of the CCD matrix. After reading the description of the defect and looking at the pictures, the camera owner will understand that the image on its display and the picture quality is not associated with camera settings. Also on site is published by a variety of tips for users.

Touch Panels

BA more advanced version – the use of external IR receiver or IR repeater (IR-sensor small signal that can be installed in another room and connect to the device in the zone). Then run, say, DVD-player or receiver can be directly in the second zone with his full-time remote control, the majority of today’s models receivers serve as the central switching unit AV-systems, there are special connectors for infrared repeaters. Also, many modern AV-equipment is the so-called trigger ports (usually with 12 V), which are designed for simultaneous operation of multiple components. For example, you can enable video in sync with the sinking of a motorized screen, and the inclusion of the second zone (kitchen) LCD TVs to quietly monitor the development of the plot, while brewed coffee … In a complex multi-systems that have one or two controllers, control is exercised by means of desktop or embedded in the wall panels control – keypads or touch with a color LCD screen. Keypads are practical, but this is the last century. Touch panels offer significantly more features, and produces a limited number of companies.

Touch panels can not connect on their own – because, apart from a complex assembly, and they require special programming to meet specific requirements. This is an extremely difficult job, which is done by qualified installers equipment. But this system makes it easy to adjust the sound in any area of the apartment, choose a variety of signal sources and to manage them on the spot. There are also portable touch panels (Rather, by the way, dear – 6 th at. Is) able to replace multiple wall-mounted models. Sometimes in a luxurious installations can be found a dozen wall panels and a couple of portable – it’s very expensive equipment, in which, by and large, the panels overlap each other.

The final element – the speakers and video output device – create the least difficulties in the installation, addition to the traditional speaker now increasingly used embedded speakers, mounted in the ceiling usually (In Ceiling) or wall (In Wall). The second area with built-in speakers is becoming increasingly popular – especially because of the invisibility equipment in the interior (included are the outer limits for painting). Bathroom produced special waterproof model, the AU, which can be installed in the ceiling rack. Speaker cables for the “insertions” extend above the suspended ceiling with low current and power cables. Embedded acoustics produce almost all the major manufacturers of traditional speakers, and available in Russia range includes products several hundred (!) brands.
