K40 mine fan

K40 mine fan vibration reasons 1, K40 mine fan impeller assembly defects (beating), friction, misalignment will cause the fan structure and resonance induced vibration. 2, support inadequate (resonance) anchor bolts loose or missing, the access door loose, vibrations occur due to vortex shedding panel issued creaks like, and with the exhaust pipe of the fan. 3, the motor eccentric (electrical and mechanical) vibrate. 4, due to the vibration source pneumatic blade adjacent section of the twist angle deviation "of 0.5%, an arbitrary cross-section twist angle deviation <1%, petiole, blade and hub selection of materials in line with national requirements and regulations and the mechanical properties of the drawing test, K40-8 -26 mine fan, K40 mine fan, K40-8-NO.11 fans 4KW mine fan K40-8-NO.12 fan 5.5KW mine fan K40-8-NO.13 fan 7.5KW mine fan K40- 8-NO.14 fan 11KW mine fan K40-8-NO.15 fan 15KW mine fan K40-8-NO.16 fan 22KW mine fan K40-8-NO.17 fan 30KW mine fan K40-8- NO.18 fans 37KW mine fan K40-8-NO.19 fan 55KW mine fan K40-8-NO.20 fan 75KW mine fan K40-8-NO.21 fan 90KW mine fan K40-8-NO. 22 110KW fan mine fan K40-8-26 fan, K40 mine fan K40-8-NO.23 fans 132KW mine fan K40-8-NO.24 fans 160KW mine fan blower 200KW K40-8-NO.25 K40-8-NO.26 mine fan blower 250KW installation angle deviation mine fan K40 mine fan blades and guide vanes is not more than plus or minus 2 percent nominal worth, blade mass (KG) on the impeller difference between the maximum no more than 5%, according to reduce principle unbalanced load for each blade, and the blade sequentially arranged in a balanced program circumferential position, and later assembled in balancing machine dynamic balance and static balance test to ensure the accuracy of the impeller balance. Fan impeller rotor balance the national JB / T9101 requirements, balance level of not less than JB / the G4 standard T 9101-1999-.
