These days concerned about the centrifugal fan under the energy-saving skills, and now let us up to share with you:
When the high-pressure centrifugal fan is operated, there are two areas where the pressure is high and the pressure is low. At the same time, there is a certain gap between the moving part and the fixed part, which causes the fluid to leak from the high pressure area through the gap to the low pressure zone , The roof fan gas leaks from the gap between the fan shaft and the volute, creating an external leakage loss. Here to talk about the transformation of high-pressure centrifugal fan method:
HTD50-11 fan initially gap δ to 17mm, due to the long use of the fan, the impeller wear, the collector has rust, no matter how we debug, δ is also between 10 ~ 12mm, air volume pressure is still difficult to achieve satisfactory degree.
The use of physical methods to reduce the gap is too large, need to replace the parts, or let the machine scrapped, which are uneconomical. We try to use the chemical method to narrow the gap, that is, within the gap δ evenly filled with powerful universal glue JZ-AB. The glue is high in strength, water resistant, oil, acid, alkali, heat and aging resistance, suitable for wide temperature, non-toxic, non-flammable, long storage period, suitable for bonding gold, silver, copper, iron, aluminum, glass , In the machinery manufacturing, maintenance, agricultural machinery, furniture is widely used.
