Fan vibration in shaft and bearing wear solutions - bearing knowledge

Blower fan is a kind of enormous quantity wide as general machinery equipment, almost all industries have used. In the fan fault, the vibration is a kind of to produce a great impact on the environment, such as production, operation, failure, with the improvement of industrial development of fan performance requirements, fan design and manufacturing technology is also constantly improve, the vibration fault of also more and more complicated. Let's have a look at the fan vibration reason have? 1. The vibration of the fan mechanical aspects ( 1) The rotor vibration caused by the unbalance of the rotor vibration manufactured by the original error caused by the imbalance or installation quality imbalance caused by uneven; The bending deformation of the rotor, rotor parts loose or rotor parts of uneven wear, etc. ( 2) When installed system vibration caused by the error of prime mover and work machine in the right connection; Bearing deflection or different heart; Due to the rise of temperature of the prime mover and work machine in running different heat caused by wrong medium; ( 3) Collision between dynamic and static parts or vibration caused by the friction of caused by bad installation in the process of running rotor deformation or rotating and stationary parts of friction; ( 4) Bearing vibration caused by the wear and tear of damage due to bearing quality or poor maintenance operation, in the cause of fan vibration at the same time also will cause the shaft wear and tear. 2. The vibration of the fan working medium ( 1) Vibration force caused by the airflow, the airflow into the fan working condition caused by the change of pressure and flow rate of change; ( 2) Airflow to corrosion caused by vibration and impact of the blade: uneven dust concentration in air flow, make the rotor mechanical instability; Gas corrosion of blade rotor imbalance. These vibrations, some of them are caused by random factors, some with fan fault has a direct relationship; ( 3) Lubrication system caused by the vibration, the dynamic behavior of the oil supply system caused by bearing various forms of vibration, oil film vortex vibration and shock can also cause of oil film fan. Vibration fault analysis and detection methods applied at present a lot of, but are not perfect. And diagnosed after the corresponding problem without corresponding solutions, maintenance maintenance time maintenance technology lags behind. In the face of the fan vibration cause, specific to resolve, such as impeller corrosion, wear, dust caused by vibration must be disassembled to repair. And for shaft after wear and tear caused by vibration, can implement site repair. Fan vibration in shaft and bearing wear of solutions for tackling the current fan bearing repair scheme, adopt the traditional repair welding, brush plating, thermal spraying technologies such as is common. These technologies for complex process conditions and the environment and limited, in the face of the fan bearing wear or sudden damage caused by the axis bearing chamber wear problem, the process is obviously insufficient, unable to do fan shaft and traditional repair welding repair technology can cause thermal stress, prone to axial bending and aggravate vibration; Long downtime maintenance also caused economic losses and safe hidden trouble. Sauvy carbon technology of polymer materials, a kind of cold welding ( Binding) Technology, online repair process does not produce high temperature, good to protect equipment from damage of ontology, and in the process of repair is not restricted by axial uneven wear amount. Material advantage is good cohesive force, good pressure resistance, shock resistance, and have the elastic deformation of metal, etc. Carbon nano polymer materials in use process does not produce metal fatigue wear and tear on the premise of normal equipment maintenance, the service life of repaired even higher than the service life of the new parts. Sauvy industrial building equipment maintenance traceability system, AR augmented reality technology, and new polymer materials, carbon nanotubes made 'service +' new pattern of the trinity, effectively solve the data connection to the underlying equipment maintenance, maintenance fast response slow and reliability problems, direct and accurate to the pain points of the manufacturing equipment operational management and demand, promote realize intelligent manufacturing and intelligent manufacturing operations twin-engine advanced manufacturing industry development. Sauvy carbon nano polymer materials as a kind of high-tech functional materials, the future can not only change the way the user maintenance, and make the maintenance more simple, faster and more efficient, more economical, more environmental protection, equipment cycle longer life. Caused by wear and tear down, for example, in view of the driving part, basic realization of the 3 ~ 6 hours rapid repair and restore production.
