The fan bearing wear field repair

Cement industry dust collecting fan tail exhaust fan is waste, common power is larger, large flow, high speed compare with, fan running accuracy of bearing parts in the process of operation request is higher, at the same time, the impeller dynamic balance calibration is the key. Due to the use of harsh, in the process of long-term operation, smooth system once the present problems of bearing will incur fans present serious affect consumption.     Fan bearing wear of main reason: & emsp;   1) Bearing short smooth, due to the working temperature is higher, formation bearing damage and wear bearing;     2) Size tolerance, due to the bearing and bearing clearance between the formation of relative movement and wear;     3) Bearing axial channeling, bearing gland not formed bearing pressure or bearing a size too big can't locate, fan form the axial moving while I wear during operation.     Traditional repair process & emsp;   About needle bearing wear, traditional online technology to repair plan has the following categories: ( 1) With non-standard sets ( 2) Pitting, direct bearing assembly ( 3) To change & emsp;   Low set non-standard sets & emsp;   Mosaic of non-standard sets, it is necessary to logoff machining disposal, about fan and other important equipment is difficult to stop production for a long time to repair, enterprise general won't adopt this technology.     Low scutching point & emsp;   Play pitting repair technology is a kind of emergency measures, and wear very small place, only after repair of the bearing inner ring and shaft fit only for contacts, so in the operation process under the condition of large load, pitting susceptible to fatigue wear, use of life is short, can only be temporary emergency.     Low change & emsp;   The disposal measures to change the new parts is the most simple, the feature is about small devices or components is match, both sides will Jane measures, but the large equipment, remove the complex, high cost of capital equipment, common to introduce and parts purchasing cycle is long, continuous consumption enterprise hard to wait.     Therefore, bearing an attack and wear, will use the repair technology of how to become a big problem, now, a new technology, sauvy carbon nano polymer technology, is arises at the historic moment, just deal with the technological fix on the board.     The fan speed: 960 r/min. Power: 710 kw; Bearing diameter: & Oslash; 120mm； Bearing model: 22224; Bearing a 58 mm width, the wear depth: 1 ~ 2 mm or so.     Sauvy industrial carbon nano polymer materials field repair the fan bearing a wear & emsp;   Sauvy industrial carbon nano polymer repair technology is the application of carbon nanotubes polymer data characteristic of the mechanical properties and corresponding repair process online repair including roller press, roller mill, blower, hoist, motor, reducer and other large axial of wear and tear.     Repair process is simple: 'sauvy tooling repair process' first stop the disposal of the wear appearance, then put the carbon nanometer polymer materials applied directly to a specific part of the wear and tear, heat with repair tooling complete repair materials forming and stop after curing. Repair data size to the bearing design size, meet the wind turbine in the parts of the request.
