Choosing to install Penoizol. In our time the market provided penoizol very many varieties of equipment from different manufacturers. Any newcomer who wants to do this business, it is hard to make your choice. As said head spin. In his article, I want to clarify what is hidden under the beautiful promotional statements. On the basis of ethical considerations, concrete installations on any question, I will not.
So. Before you have to buy set for itself to the conclusion: what you need it. If you need to make a warming room, and several other objects, so to speak, for themselves and their, you do not need to acquire doroguschy, super setting. In this case, you can do a minimal budget. You can do the installation GZHU own or buy ready-made.
In any case you do will be cheaper than hiring contractors. When it comes to what you decide to do penoizol professionally, then determine the choice difficult. There are many companies and firmochek that shine with their colorful ads. Everyone praises his invention to the extent their capacity and sling mud at competitors. But on some points, many tend to hold back. Let's try to consider these points: Installations using pump 10 and the NS NS 6. Gear pumps 10, a gear hydraulic pump. Some manufacturers use its facilities to supply the resin, but! To obtain the average dosage 2l/min. The pump shaft must be rotated at 200 rev / min. Everything seems to be nothing, but as soon as the output of formed a high pressure pump, and it is always different, depending on the lifting height of foam generator, the exact dosages to speak no longer necessary.
Tell me, what heating equipment better suited for a wooden house, how to find it? Answer: Generally speaking, the principle of selecting equipment for heating wood home, similar to the principle of selection for any home, because here it all starts with the calculation of heat the building. But the wooden houses have their own specific characteristics. Which, let us consider a dedicated your question article. “Building a wooden house” these days building a wooden house, in contrast to earlier times – it is rather a certain kind of philosophy, rather than a necessity. Our ancestors alternative to the wooden house was not, as the house of stone, brick, or could at that time afford not many. However, today, despite the abundance of modern materials and technologies, wooden house still even more widespread than stone.
features a wooden house first and most distinctive feature is the material itself. Wood has many unique properties and characteristics. For a start – a tree is a natural, living material created by nature itself. However, it is very, very durable. Have survived wooden buildings dating back over 700 years. But today, thanks to the abundance of various protective coatings for wood, it life can be even more without losing what is important, their external aesthetics and not collapsing structure. Incidentally, the oldest wooden house in Sweden has been preserved to our days is, in the town of Moore (Mora). According to scientists it was built around 1237. And the oldest tree is a pine, located in the , its age is estimated at 4,500 years. The advantages of wood.
The new pump NSH 10 is not designed to operate at such low speeds (Rated speed of the pump shaft 1000 rev / min) and has a constructive overflow capacity, which just shows an increase in output pressure at low engine speeds. The more wear and tear pump lower frequency of rotation of the shaft and lower the viscosity of the fluid, the greater the ability to bypass. Dosage error can exceed all expectations. And when you consider the fact that sometimes the resin sold already divorced water and at the same concentration and viscosity, respectively, is still below that in this case, more can be said about the accuracy of dosage? And not everyone will be able to rotate the motor shaft of the pump under load. Claimed manufacturer's recommended engine power to the shaft NS 10 – 8 kW. NS 6, structurally the same as the NS 10. The main difference is that the volume of the pump is 6 cm3.
This suggests that the pump is 100 rpm should give 0.6 liters fluid under ideal conditions (laid turnovers, minimal wear, etc.). So, for 2uh liters per minute, we need to rotate the shaft at a speed of 333 rev / min. Dosage error in these revolutions, will konechnozhe minimal in comparison with the NS 10. Only here the price of these pumps is high, and not so easy to buy them. Pumps of this type are rare in the industry. There are, of course, a big plus when using the NSH.
Brass fittings (from English: "fit", "mount", "collect") 16-17 position brass fittings are used everywhere. We face them every day in his apartment – in a bathroom or closet. Fittings made of brass, in particularly necessary when connecting a washing machine, water meters, boilers and other equipment requiring connection to the pipeline. For brass fittings include the following: Fittings made of brass – the coupling (Used for direct connection to pipe); 16.8 Fittings Brass position – knees (change the direction of the line), 1.1 position Fittings Brass – tees, crosses (forks pipeline) 18/10 position Fittings made of brass – the plugs (plugs on the pipes until the moment of connecting cranes) and 6.6 position futorki, bochata, nuts, sleeves, adapters, etc. Among the variety of types of material making up the fittings, brass fittings have many advantages, which include durability and resistance to the transported medium. To avoid oxidation (electrochemical corrosion) in contact with brass and aluminum layer pipes, fittings, brass coated with nickel or chromium. Also, using special Teflon pads to prevent the direct contact of brass fittings and AL. Currently, our catalog is a wide range of quality brass fittings all size that will allow you to maximize installation, significantly reducing the cost and time.
Brass – a double or multi-base alloy of copper, where the main alloying element Zinc is sometimes with the addition of tin, nickel, lead, manganese, iron and other elements. -3000-5500 Density kg / m Specific heat at 20 C – 0.377 kJ kg-1 K-1 Resistivity, ohm 0.07-0.08 m Temperature melting brass, depending on the composition reaches 880-950 C. With increasing zinc content the melting temperature is lowered. Brass is well sealed and rolled. Although the surface of the AL, if not lacquered blackens in the air, but the bulk is more resistant to the action of the atmosphere than copper. It has a yellow color and perfectly polished. Bismuth and lead are harmful to brass, so as to reduce the ability of the strain in the hot condition.
