The range of circulating pumps on the market inmore focused on the needs of private users. The introduction of reliable and functional equipment in the organization of communication infrastructure has long been a prerequisite in equipping households. However, the higher the load on the engineering system, the more stringent the requirements for its component parts. Not every manufacturer can offer both a durable and productive station for pumping liquids. Among the exceptions are Wilo, a circulation pump of which is presented in several variations. At the same time, all models differ in well-thought-out ergonomics and the availability of modern controls.
The manufacturer solves the problem of weak circulation.the coolant in two ways - pumps with a "wet" and "dry" rotor. The design of the units of the first group assumes that the working shaft will always be in a liquid medium. That is, during operation, the coolant lubricates the functional elements of the device, which saves the user from the need for regular maintenance.
Принципиально отличается концепция «сухого» Rotor from Wilo. In this version, the circulation pump has a rotor separated from the working part. A special sealing ring separates the functional parts, so it is necessary to periodically check the engine and its components for the presence of suspended particles. In addition to the nuances of maintenance, there are other differences between the two types of circulation pumps. Models that imply shaft wetting do not make much noise during operation, but the alternative version benefits from high performance.
Поскольку многое в использовании насосов зависит from the connection parameters, first of all you should calculate the voltage and frequency of the network. For models of this brand is characteristic of the support voltage of 230 V and the frequency range of 50-60 Hz. Further, the indicator of working pressure is taken into account, on which, in principle, the possibility of maintaining circulation at the proper level will depend. The manufacturer produces models with a pressure level of 6 to 10 bar. However, there are other indicators for Wilo equipment. A circulation pump in a special version of the Top line, for example, provides 16 bar. You should also take into account throughput and pressure indicators. As for the volume of consumption, it leaves an average of 3-5 m3/ hPower (in terms of pressure) varies on average from 4 to 7 m. In each case, it is important not to forget the parameters of the circuit along which the coolant will circulate, but these data are selected individually, depending on the needs of the house.
Это семейство представляет модели с «мокрым» rotor and threaded connection type. To adjust the power indicators, the design provides for the possibility of setting three rotational speeds. It is possible to use this unit both for heating systems, and in complexes of cold water supply, as well as in combination with climatic equipment. As for the direct installation and maintenance, the circulation pump Wilo Star is one of the most profitable solutions. Its simple hydraulic device does not require the use of special seals for the shaft and protective relays. Since the pumped coolant independently lubricates the bearings and provides cooling of the rotor element, we can speak of a high degree of autonomy of this unit.
В некотором роде это классическое исполнение models of this type, which combines traditional design and modern automatic systems. In this case, the threaded joint type is interspersed with flange elements, which adds flexibility to the device configuration in terms of installation. They use such models in the same heating, air conditioning and cooling systems. Depending on the modification, the introduction of the unit into industrial communication complexes is also allowed. Among the technological advantages can be noted branded control systems Wilo. The circulation pump in the Top-S series has a built-in electronic shutdown system. This applies to both three-phase and single-phase installations. External control is implemented through a special module, equipped with a light indication and alarm devices.
This line represents pumps working with"Dry" rotor. This is a single-stage centrifugal unit that can be used as a circulation unit. Such models, in particular, are used in the equipment of residential buildings, as well as industrial infrastructure and agriculture. Both cold and hot water can act as a working medium. Since the circulating pump for heating Wilo in the BAC version does not provide for the possibility of passive lubrication by working medium, you should initially prepare for regular maintenance. However, if we are talking about pumping clean water, then the list of such measures may be limited to checking connections and technical and operational parameters.
Owners of houses for circulationcoolant and water supply meets the equipment of this manufacturer, note the reliability and durability of technology. Mechanisms work flawlessly over the long term, without requiring special technical measures. But there is also criticism that Wilo circulators receive. The price is 6-10 thousand rubles. for basic modifications, causes negative feedback. However, well-known brands produce more expensive products of the same class.
The company's approach to the development of pumpingThe equipment has several distinctive features. First, the manufacturer pays a lot of attention to specialized constructional designs, releasing to the market and quite original modifications. Secondly, the circulating pump for heating Wilo has a wide provision of electronic systems. The development of these two areas allows designers to open new frontiers in the technical organization of the communication infrastructure of a modern home. For example, the introduction of automatic systems of regulation allows to optimize the control of the coolant. As a result, the engineering network becomes more economical and at the same time more productive.
