Induced draft fan coupling insulation transformation to do so!

Induced draft fan coupling insulation transformation to do so! 2020 - 08 - 27 in response to low emissions, to realize saving energy and reducing consumption at the same time, get in shanxi electric power generation co. , LTD. Of induced draft fan with China 'steam electric double drive' transformation. But there is an obvious vibration after transforming the fan bearings, gears mesh clutch can't wait for a phenomenon, after the collapse of the examination found that damage to the cause of damage to the motor shaft current. The measured motor current 30 a runtime axis, causing corrosion. In order to solve the problem of insulation, production technology department, the director of engineer yan attention is reformed. Retrofit scheme on the basis of the original coupling design improvements, expand the coupling bolt hole diameter, adding epoxy resin insulation sleeve, and in combination with 3 mm thick insulation board, insulation between the motor shaft with variable speed clutch shaft processing. And through the strength check calculation verification, fully meet the requirements of the strength of the coupling torque. After modification, the formation of cutting off the shaft current loop, successfully solved the problem, ensure the normal operation of the equipment.
