The circulation pump is a type of vortex pump and is used to cause liquid flow in heating and cooling installations. Otherwise it can be said that the circulation pump forces water circulation. This phenomenon was used for the first time in 1929. The most important element of the circulation pump is the engine that drives the shaft and the rotor. In traditional models of the chipping pumps, the engine is separated from the liquid. Nowadays, however, homemade pumps are much more popular - he has a widespread or high -performance ECM pumps with an electronic engine.
How does the central heating pump work?
Pressure heating systems use circulation pumps to force water circulation. C.O. circulation pump significantly improves the operation of the heating system. Using it, you do not need to use large cross -section pipes or install a boiler in the basement. The circulation pump can be built into the boiler immediately. Otherwise, the pump should be purchased yourself, but its installation is not complicated. Central heating pumps are compact and light. The principle of their operation is based on creating the pressure difference between the inlet and the outlet from the pump. The water is suck by the pump from the boiler. The stainless steel rotor is powered by an engine and transmits liquid potential and kinetic energy. In this way, its pressure and speed increases.
In the cast iron body, the kinetic energy is converted into potential, i.e. the pressure grows even more. It is thanks to him that it is possible to cause a water circulation that circulates in heating pipes and reaches the radiators. In single -family houses, homemade pumps are used, in which the engine is immersed in the liquid. Their durability is about 15-20 years. C.O. circulation pump It should be equipped with an automatic vent valve and a mesh filter. Remember that filters should be cleaned regularly! Modern C.O. They not only increase the comfort of using the installation, but also allow you to reduce up to 50% of electricity consumption.
How to choose the right circulation pump?
Flamedic circulation pumps for central heating do not require maintenance, lubrication or replacement of seals. However, it is very important to choose their parameters correctly, because installing too small or too large pump will have negative financial and utility consequences. For a large circulation pump will take disproportionately a lot of power, and its parts will wear out faster than they should. However, choosing a small pump can cause the installation to have problems forcing the needed water flow, which will result in the failure of the rooms. The most important parameters you should pay attention to are the efficiency, pump pressure, power consumption, rotor speed and the level of noise generated. The parameters of the circulation pump should be adapted to the length of the pipes, the amount of heaters and the installation resistance. The pump performance, i.e. lifting height and flow rate, should be specified in the installation design. In the event that the investor does not have such information, it will be wise to use the help of a specialist when making calculations.
Remember that pumps with greater performance will be needed for underfloor heating and in several -storey houses. It is worth focusing on electronic controlled circulation pumps that have the ability to automatically adjust the engine speed. Such pumps are recommended for installation with thermostatic valves. Rotation adjustment is usually three or four -speed. The pump should work in the highest gear most of the time. The power consumption parameter will condition operating costs. Rational operation of the boiler will only be possible if the parameters of the circulation pump are correctly adapted to the requirements of the heating installation.
