The fan vibration of shaft and bearing wear processing plan

Blower fan is a kind of enormous quantity wide as general machinery equipment, almost all industries are used. In the fan fault, the vibration is a kind of great influence on consumption, operation, environment and other problems, along with the progress of the industry to carry out the performance of the fan is requested, the fan design and manufacturing technology progress from time to time, also presented the vibration problem is becoming 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 vibration of the rotor imbalance provoked: the vibration of the rotor imbalance provoked by the original manufacture error or device not average cause uneven quality; The bending deformation of the rotor, rotor parts loose or rotor parts of uneven wear, etc. （ 2) When provoked device error in the system of vibration: device of the prime mover and work machine of cohesion; Bearing deflection or different heart; In operation due to the rise of temperature of the prime mover and work machine is different form the right heat medium; （ 3) Collision between dynamic and static parts or the vibration of the friction stir: bad form running rotor deformation in the process of the device or rotating and stationary parts attack friction; （ 4) The vibration of the bearing wear make up: as the bearing quality or work remaining bad formation damage, at the same time also can form the formation of fan vibration shaft wear and tear. 2. The vibration of the fan working medium provoked ( 1) The vibration exciting force, the airflow into the air pressure and flow of the fan changes the change of working condition; （ 2) On the impact of the blade and the vibration of the corrosion form: uneven dust concentration in air flow, make the rotor bearing instability; Gas corrosion of blade rotor imbalance. These vibrations, some of them are formed by random factors, some with a direct relationship between the fan fault; （ 3) Smooth system formed by vibration, the dynamic behavior of the oil supply system the vibration of bearing a variety of ways, the oil film vortex and the oil film oscillation will also be able to make up the fan vibration. Currently USES the vibration problem of a lot of analysis and detection method, but are not perfect. And diagnosed after the corresponding problem no corresponding processing plan, forming the maintenance maintenance technology lag time. In the face of the fan vibration reasons, refuse the demand detailed information, such as impeller corrosion, wear, dust provoked the vibration of the disassembly repair must stop. And for shaft wear after the vibration of the form, to perform on-site repair. Fan vibration of shaft and bearing wear process in dealing with the current fan bearing a repair plan, adopts the traditional repair welding, brush plating, thermal spraying technologies such as compare with common. These technologies for complex process conditions and site environment was limited, in the face of the fan bearing damage of sudden formation of axis wear or bearing chamber wear problem, the process is obviously not possible, and the traditional repair welding repair technology will form the fan shaft thermal stress, easy to present shaft bending and aggravate vibration; Long downtime maintenance also form the economic losses and peace. Sauvy carbon nanometer polymer materials technology, a kind of cold welding ( Binding) Technology, online repair process does not produce high temperature, good maintenance equipment from damage of ontology, and in the process of repair is not restricted by axial uneven wear amount. Information advantage is good cohesive force, good pressure resistance, shock resistance, and have the elastic deformation of metal, etc. Polymer materials in the process of using carbon nanotubes will not produce metal fatigue wear and tear, in normal maintenance under the premise of care equipment, its use life and higher than that of the new parts after the restoration of life. Sauvy industrial building equipment maintenance traceability system, AR strengthen ideal technology and carbon nano polymer materials, the trinity of 'service + made in new forms, effective device to deal with the underlying data connection, fast response and slow maintenance firm sex, direct, precise cutting manufacturing equipment pain points and the demand of operations management, promote manufacturing complete intelligent manufacturing and advanced manufacturing industry to carry out the twin-engine intelligence operations. Sauvy carbon nano polymer materials as a kind of high-tech function data, not only can change the user's maintenance in the future, and make the maintenance more simple, faster and more efficient, more economical, more environmental protection, equipment cycle longer life. For example, for driving part wear incur downtime issues, simply complete the scene 3 ~ 6 hours rapid repair and restore consumer; Sauvy industrial fan axis wear vibration pictures sauvy processing industrial fan bearing wear vibration image processing
