water tube d type boiler installation

Mainly use electric pipe washer, flat shovel, steel wire brush and hand hammer and other tools for mechanical descaling. This method is simple, low cost, but large labor intensity, poor scale removal effect, easy to damage the metal surface, only suitable for small water tube d type boiler installations with small scale area and simple structure, which is convenient for mechanical tools to contact with scale. In recent years, due to the application of high pressure water gun for cleaning, the mechanical descaling of hydraulic flushing developed rapidly. The effect of this kind of high pressure hydraulic descaling has been greatly improved compared with the original mechanical tools, and it is more safe and convenient. But.

Boiler Fan analytical work principle and common installation and maintenance methods? Boiler Fan works: it relies on mechanical energy input, increase the gas pressure of the gas sent to the mechanical side by side, it is a slave fluid machine. Works in induced draft fan and the compressor turbine is substantially the same, but due to the low gas flow rate, little change in pressure, the gas is generally not necessary to consider the change in specific volume, i.e., the process gas as incompressible fluid. Boiler Fan application to blower widely used in factories, mines, tunnel ventilation, cooling towers, vehicles, ships and buildings, dust emission and cooling; the water tube d type boiler installation and industrial furnace ventilation and the air; an air conditioning equipment and household appliances cooling and ventilation equipment; grain drying and should select; tunnel and hovercraft air source and the pneumatic propulsion.
