Circulation pump action and installation requirements in domestic heating systems

Not only in industrial production will be used in the circulation pump, and even home heating systems also need to install the circulating pump, helps to simplify the installation of the entire heating process, optimize the system, and to overcome the system due to air bubbles caused by cycle blockage The problem.
In the case of natural circulation, the circulating pressure of the heating system is derived from the difference in the specific gravity of the water, and the cycle pressure is usually very small. Once the bubble is generated, the circulation is seriously hindered. It is also because the natural circulation of power is very small, so usually a very thick trunk to reduce system resistance, even so, the system often recurring or heat problems.
However, after the installation of the circulating pump is different, whether it is cooling, energy consumption or the sustainability of the cycle can be good to further promote the heating system, the stability of heating. But the attention can not be ignored, or even a circulating pump can not function properly.
Before installation, check whether the circulating pump inlet and outlet are blocked by foreign matter. Rinse the debris in the system pipe as far as possible before the system is put into the system, so as to avoid blocking the impeller around the impeller during the operation of circulating pump, and cause a certain degree to the parts. damage.
Install the circulating pump when you try to force soft, do not vigorously, so as not to damage the pump; circulation pump inlet and outlet should be equipped with a live joint, the purpose is to facilitate the assembly and disassembly. The connection of the system should adopt the three-wire plug with ground wire, and the ground wire end should be connected with the motor shell to ensure the safety.
Although the circulating pump itself is relatively low noise, but still need to check whether the rotation, the simpler way is to listen to a screwdriver to listen. In order to ensure safety, do not circulate the pump for a long time in the state without water running.
