Einhell szivattyúval

Source : http://ezermester.hu/cikk-5039/Belviz_ellen

Cikkünk írásakor még zömmel fagyott a föld, de az átázott talaj és a megfagyott belvizek azt sejtetik, hogy olvadáskor még jelentősebb belvízproblémák előtt állunk. Az erősen telített talaj szinte egyáltalán nem képes már elnyelni a csapadékot; ami esik vagy olvad tavasszal, az mind belvízzé válik. A védekezés lehetőségei közül most a belvizek szivattyúzására alkalmas szivattyúfajták közül az Einhell készülékeit tekintjük át.

A belvízvédelemhez leginkább a szennyvíz szivattyúkat ajánljuk, mert az átemelendő víz ritkán tiszta, sokkal inkább sáros, piszkos, szennyezett. Az Einhell választékában az előnyösebb árú kék színű, valamint a magasabb osztályú piros színű gépcsaládban is több típust tudunk ajánlani. Ezek típusszáma RG-DP-vel kezdődik (a DP a Dirty Water=szennyezett vízre utal); teljesítményük 370 W-tal kezdődik, de még a kékek között is találunk 7-800 W teljesítményűt, pirosban pedig ezer watt feletti is van. Az elárasztott terület vagy épületrész leszivattyúzásánál nagyobb emelőmagasságra rendszerint nincs szükség. Az 5-10 m közötti emelőmagasság általában elegendő, hiszen az átemelt vízzel nem öntözni kívánunk, a kifolyási helyen már csak minimális nyomásra van szükségünk.

Egy elárasztott épületrész viszonylag tisztább vizének kiszivattyúzására a közönséges búvárszivattyú (merülő szivattyú) is alkalmas lehet, persze ha mégis van szennyeződés, akkor ez a fajta hamarább eltömődhet. Egy folyamatosan újra és újra telítődő pincéből azonban egyáltalán nem szabad szivattyúzni a vizet, mert „kutat csinálunk belőle”, és teljesen kimosódhat az épület alapja, falazata.

Minden merülő szivattyú jellemző adata a megmaradó vízszint. Ez az a vízmagasság, amit a szivattyú már azért nem tud felszívni, mert a szívórácson, vagy szennyvízszivattyúknál a beömlő nyíláson levegőt is szív. Ha az a cél, hogy a szivattyú teljes egészében víztelenítse a helységet, célszerű annak legmélyebb pontjára egy, a szivattyút befogadni képes mélyedést, ún. zsombot kialakítani, és ide helyezni a szivattyút. Így a teljesen leürített helységben csak ebben a zsombban marad víz. A vízgyűjtőt - amelyből a szivattyú dolgozik - úgy kell méretezni, hogy a szivattyúzás végén a csőből visszafolyó vizet magába tudja fogadni.

Zsombba való telepítéshez legcélszerűbb a beépített szintkapcsolós szivattyúk közül választani. Ha a merülőszivattyún az úszókapcsolót felemelt állapotban rögzítjük, akkor alaposan lecsökkenthető a megmaradó vízszint, de ebben az üzemmódban nem szabad a szivattyút felügyelet nélkül hagyni, mert szárazon futva igen rövid idő alatt véglegesen károsodik.
A felszíni vagy kerti szivattyúk kevésbé alkalmasak az ár- és belvízvédelemre, de azért próbálkozhatunk velük egy terület leszivattyúzására. Ezek nem merülnek (nem is merülhetnek) be a vízbe, hanem a felszínre telepítve szívócsövön szívják fel a vizet, majd nyomócsövön továbbítják azt. A felszíni szivattyúkat az első üzembe helyezés előtt teljesen fel kell tölteni vízzel, és csak ezt követően szabad beindítani. A felszíni szivattyúk nem járhatnak szárazon, üzemelésükre folyamatosan figyelni kell. Nagy emelőmagasságuk viszont adott estben jól jöhet, hiszen a 2-3 bar-os nyomásuk akár 20-30 m fölé is tudja emelni a vizet; pl. távolabb és magasabban lévő gát mögé nyomathatjuk vissza.

Az Einhell kerti szivattyúi közül is tudunk kék és piros színű gépeket egyaránt ajánlani; típusjelük BG-GP, illetve RG-GP (GP=Garden Pump= Kerti Szivattyú). Ezek mind elektromos meghajtásúak. A belvízi problémákra való tekintettel mégis inkább egy benzinmotoros változatot emelünk ki, hiszen az elárasztott területeken gyakran áram sincs. A BG-PW 48 típusjelű szivattyút egy 6,5 LE-s négyütemű motor hajtja, és több mint 500 liter vizet képes átemelni percenként.

Gondoljuk tehát meg mi is a célunk a szivattyúval. A kisnyomású merülőszivattyút pincék víztelenítésére, magas vízszintű talajvizes kúthoz (a talajvízszint csökkentésére) javasoljuk. Általában tiszta, vagy csak kevéssé szennyezett vízhez használható.

Ha a szivattyúzandó víz darabos szennyeződéseket tartalmaz, akkor szennyvízszivattyút célszerű alkalmaznunk. Közös jellemzőjük, hogy igen nagy mennyiségű folyadékot tudnak szállítani, de csak alacsony nyomással. A nagy átáramló keresztmetszet nagy résveszteséget takar, ezért ezek a szivattyúk a legkisebb fojtásra is igen drasztikus mennyiség-csökkenéssel reagálnak. A szennyvíz szivattyú nem tömítődik el, ha a szennyvíz darabossága egy értéken belül van.

Regulated Pressure for Radiant Heating Systems With PEX Manifold

Fixtures of many kinds are required to set up pipes lines to transport liquids, slurries and gases. It is a sort of operating device required where the fluid has to be distributed into many channel. According to the dictionary the exact definition of manifold is: "Manifold is a cylindrical pipe fitting, having a number of lateral outlets, for connecting one pipe with several others." There are manifolds available in a multitude of variety to suit every plumbing requirement. PEX Manifold spin closed system is the best for radiant heating systems as it has the capacity to endure high and freezing temperature conditions.

PEX manifold spin closed systems are used at home for equitable distribution of hot and cold water through the house. The PEX manifold spin closed system is predominantly in the radiant heating systems where the hot water from the boiler has to travel to all the rooms of the house. The water comes back to the boiler from all the rooms of the house. It is a continuous process. The boiler feeds the rooms with hot water through a manifold where each outlet carries the water to different room. In the same way water is collected through a manifold into a single feeder pipe for the boiler. The pressure in the pipes is adjusted with the help of a pressure gauge. The heat of the water opens the value and lets the hot water out of the boiler and into the rooms thus it creates space for the cold water to flow into the boiler.

The advantage of using the PEX manifold spin closed system is that all the connections are at one place and any damage or leakage can be detected immediately. It comes with a remarkable advantage to shut down partially. Water supply to one room or a part of the house can be shut down without creating inconvenience to the rest of the area. A regulated water supply with the right amount of pressure is assured by the use of a manifold spin closed system.

There is a great variety in the prefabricated PEX manifold spin closed systems for the different sizes of the PEX pipes. The configuration of the manifold can be decided depending on the need. A single manifold with divided compartment for both hot and cold water is also a PEX product worth considering. It is a very light and product and can be fitted anywhere with easy accessibility.

Solar Water Pumping - Enormous Cost Savings

The recent dramatic increases in the price of oil have hit almost everyone. Gas and diesel are vastly more expensive, and that in turn causes the price of electricity to rise as well. With oil being a finite, non-renewable resource, increased use of renewable forms of energy such as wind, geothermal, hydro and solar is once again a hot topic. I say "once again" because we were there in the 1970s but didn't learn our lesson. As soon as oil prices came down, so did our resolve to use and pursue more sustainable energy sources. No one argues the benefits of solar power, but putting it to use generally required complicated connections to the utility grid. That's becoming more common, but there's another way to use solar that makes a whole lot of sense, and that is solar water pumping.

Let's think about this for a moment. The huge advantage of solar power is that it is free and inexhaustible. The disadvantage is that it's only available when the sun shines. Theoretically you could use solar power to charge giant batteries so that electric energy would be available whenever you need it, but that is not practical. But how about putting solar to use in areas where it doesn't matter when the work gets done, just that it does get done? Pumping water is one such area. Once water is pumped from one place to another, it's available for use. It generally doesn't matter when it is pumped.

Solar water pumping is becoming quite interesting to farmers who are facing increasing costs running diesel pumps to provide livestock with water as well as water for irrigation. On top of the cost savings from not having to run diesel pumps or extend the grid, bringing water to cattle instead of bringing cattle to the water offers substantial watershed and riparian zone management benefits (cleaner water, reduced erosion, etc.). 
And portable solar water pumps facilitate rotational grazing and temporary pasture.

Solar force is also an attractive option to bring water to remote homes, cabins or campgrounds. It even makes sense to employ solar drip irrigation and pumping for gardens and homes. The technology to do all that has been around for decades. It's mature and efficient, and there are a number of government programs and utility incentives to use it. There is an initial investment, of course, but given the increasingly unpredictable cost of non-renewable energy that's no longer the obstacle it once was. And the more expensive energy gets, the quicker solar water pumps pay for themselves.

A number of well established and highly reputable companies like Grundfos SQF, SunCentric, Solaram and Solar Force offer a variety of pumps (submersible, surface, solar slowpump, etc.), pump controllers and, of course, solar panels. A complete solar pumping system requires meticulous planning, proper sizing and expert installation, but the resulting benefits are well worth it.

The bad news is that our current problems with oil will likely not go away. The good news is that we have a number of alternatives, and solar energy is one of them. Solar water pumping makes a lot of sense and it is fairly easy to implement.

Grundfos instant hot water system

Having an instant hot water circulating system has so many advantages. The top two advantages are that it saves a lot of water and that you do not have to wait for water to be heated. Instant hot water systems also save a lot of water that would be wasted down the drain and saves a lot of energy. Another advantage is that it decreases the green house gasses that get released into the air. These gasses are the result of the energy that is used to process and pump the water and during sewage. There are many circulating system these days that would offer instant hot water. The most famous one of them is provided by Grundfos szivattyú.

People view the term “instant hot water” differently. Some people say that getting hot water after 1 or 2 seconds after opening the tap is instant hot water. Some say that it has to instant as soon as you open the tap. The sure thing is that there is always a waiting period for the hot water to arrive.  Grundfos szivattyú offer this type of hot water circulating systems.

The most common view of instant hot water is that it comes after one or two of seconds after opening the water tap. If you want to know how they work, Grundfos system for instance works by having the water circulate in an endless loop. This loop starts at the water heater outlet then passed at all the fixtures and then back to the water heater once again. This circulating system is the only way for the users to get near instant hot water.

Although this Grundfos circulating system might look like a great idea at first glance, but things change after looking closer. It has many disadvantages; the first one is that it consumes great amounts of energy. As this system uses a lot of energy to keep the whole system hot and to make sure that the water at the heater is as hot as it can be. If you think about it, the energy used to heat the water costs more than the water that is being heated.

The second disadvantage is that continues circulating systems is not compatible with water heaters that have no tanks.
