Asia Pump Network News】 ã€vacuum pump sometimes use after a period of time, because of aging and other issues of vibration noise, then this time how to do it? Asia Fluid Network Xiaobian with you to analyze. Causes and solutions of the vibration of the vacuum pump Analysis 1, the vibration caused by fluid action such as the pump operating point serious deviation from the best efficiency point of operation, the blade produces uneven flow and instability of the return flow; local pressure drop causes cavitation and so on. 2, vibration caused by mechanical reasons, such as unbalanced rotor assembly, pump, motor, coupling misalignment, shaft bending: gear tooth wear, sliding bearing film shock, rolling bearing track, the ball is not round or inside and outside, the ring off, the design Irrational or thermal expansion caused by excessive pipeline resonance, anchor bolts loose and so on. Solution 1, the use of dynamic balance. It is usually possible to balance the inertia forces of the eccentric and the slide valve by means of analysis and calculation, then add the balance wheel and add the counterweight or balance wheel to the pulley. Practice has proved that this is an effective damping method. 2, Mechanical shock absorption device can be installed and removed. Most of the devices are used in high-speed pump and pump with high pumping speed. For example, the pump base is equipped with anti-vibration rubber to reduce vibration. 3, from the pump structure adjustment Pump structure from the adjustment, the use of actual needs can be designed upright, bedroom and other types of pumps, the actual use of the horizontal structure as a result of compact, low center of gravity more favorable vibration Noise reduction. 4, the use of a variety of cylinder combination structure using a variety of cylinder combination structure, of course, the number of cylinders to be reasonable, at the same time the layout to comprehensive consideration of the actual use.
