Methods To Maintain The Fan Of Pulverizer

Fans are the dynamic balance test, because of its high speed, so its balance requirements are high, especially the impeller fan is very sensitive to the imbalance of the peripheral, but its in the center of tiny sense of imbalance requirements are not high.According to this feature, prone to failure of the impeller, the following methods can be used to fix it: pulverizer if the rivethead of the impeller wear compression impeller body and wheels, welding surfacingwear rivets head back to the normal state.Pulverize the rivet hole prone to fatigue crack can be used whole root have not used the new electrode welding repair cracks, but to the impeller axis line as the center symmetry of the crack at patching the rest of the electrode to remain in the area, and then a new electrode patch relative said rivet hole cracks after the rest of the welding electrodes and symmetrical rivet repair as long as the rest of the electrode, to ensure that the solder to fill up the weight.For symmetrical rivet hole cracks also will electrode surfacing here is used to offset the weight of symmetrical rivet whole cracks at the new fill welding.Welding in accordance with the symmetrical complement method can repair the cracks.3 grinder of the impeller to a simple dynamic balance test method is also very simple.Impeller support from the hand struck gently rotate to make it reach a balanced place to stop to the lowest point swing.Emphasis can be opposite to the impeller on the spot if so, add weight to make it balance, emphasis impeller welding marks or rub off with angle grinder, but also to achieve a balance so that you can put the fan fixed to work properly.Note that the fan repair process cannot be used welding random spot welding marks left on the impeller, so as not to affect the balance of the fan impeller is less than the repair purposes, resulting in greater losses.China sand washer : http://www.Hxjq-crushers.Com/8.Htmchina impact crusher : http://www.Hxjq-crushers.Com/6.Htmsand washer : http://www.Best-crushers.Com/sandwasher.Htmcement making plant : http://www.Hxjqcrusher.Com/crusher/cement-making-plant.Htmlstone crusher : http://www.China-crusher.Com/stone-crusher3.Html.
