Now in Belarus an opportunity to learn and appreciate the high quality frequency converters Vacon. A key feature of all the drives Vacon – a high modularity as mechanical design, and software. Modular concept, developed by Vacon, is unique. Three different control unit, two methods of cooling power units, the ability to install five different boards I / O, simple to install upgrade kits are just some of the elements. Only vyberat elements necessary to you and design a frequency converter. Control units nxs and nxp can be installed separately from the power modules. Block nxs is designed for major industrial applications, which do not require high precision control signal from the sensor feedback. nxp unit can process the feedback signal and provide the best quality engine management characteristics.

The user a choice of power units with both air and water cooled. I / O cards can be used with any type of converters: the nxl can be established a board to expand the existing interface, and in nxs and nxp – up to five I / O boards. This allows you to create the necessary configuration information inputs and outputs for each specific application. nxl converters have a removable control panel with seven-segment lcd display. It is used to exchange information with the transmitter, programming and monitoring, but has no storage function parameters.

nxs and nxp a detachable control panel with alphanumeric display. It is also used for configuration and monitoring, but it has a built-in memory. This allows you to copy settings from one drive to another, and to preserve the memory of the active parameter settings for later use. Vacon nx control unit is usually attached to the power unit and is powered by it. The control unit can be powered and the external power supply 24, which allows for seamless communication with the drive for fieldbus control and reading of data even when turned off the mains.

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).
