Roots BlowerIn the process of using the vibration of the situation, so what are the reasons that lead to the vibration of the Roots blower? On this issue Roots blower editorial take you to understand.
1. Design reasons: Roots blower design is generally based on the fan's use of the environment, temperature, air volume, wind pressure, media, etc. to design, and Roots blower selection of some companies are not fully based on these factors, resulting in the existence of the following factors: fan design is not appropriate, the dynamic characteristics of the poor, vibration occurs in operation; structural irrationality, stress concentration; design of the working speed is close to or fall into the critical speed zone Thermal expansion calculation is not allowed, resulting in poor thermal alignment.
2. Manufacturing reasons: the manufacturer of the fan's quality requirements also affect the operation of the fan, such as: parts and components of poor processing and manufacturing, lack of precision; parts of poor material, lack of strength, manufacturing defects; rotor dynamic balance does not meet the technical requirements.
3. Installation, maintenance reasons: Roots blower installation accuracy requirements for fan operation plays a vital role, such as installation accuracy does not meet the installation requirements, the operation of the Roots blower will play a destructive role. In the process of fan installation, improper installation of machinery, parts and components misalignment, preload; shaft system alignment is poor; machine clearance, surplus and relative position adjustment is improper; the rotor is placed improperly for a long period of time, changing the dynamic balancing accuracy; not in accordance with the rules and regulations of overhauling, destroying the original nature of the machine with the nature and accuracy of the machine.
4. Operation reasons: in the use of Roots blower, fan maintenance, maintenance of good and bad, the quality of the operation of the Roots blower plays a decisive role. Process parameters deviate from the design value, the machine operating conditions are not normal; machine in the over-speed, overload operation, changing the working characteristics of the machine; lubrication or cooling is poor; rotor local damage or fouling; start-stop or lift speed process operation is not appropriate, thermal expansion is not uniform or in the critical zone stay too long.
5. Machine deterioration reasons: general equipment in use have a certain age, up to a certain age equipment performance will deteriorate. For the Roots blower is also true, long-term operation, rotor deflection or dynamic balance deterioration; rotor local damage, shedding or cracks; parts wear, pitting or corrosion, etc.; with the surface of the deterioration of the force, resulting in insufficient interference or loosening, etc., destroying the nature of the fit and precision; machine foundation settlement is not uniform, the machine shell deformation.
