When the melt pump is in use, because of the operating relationship of various machine parts, it is prone to vibration. The vibration phenomenon will have a certain impact on the use of the melt pump. Therefore, it is necessary to do a good job of damping to ensure the melt pump. Normal use. So what should be done to reduce vibration measures?
First of all, vibration reduction can be divided into two aspects, one is active vibration reduction, and the other is passive vibration reduction. The method of active vibration reduction is to improve the basic structure or operating state of the melt pump to control the energy generated by the vibration source to a greater extent to achieve the purpose of vibration reduction. The other is passive vibration reduction. This passive vibration reduction measure mainly achieves the purpose of vibration reduction by reducing the intensity of the vibration source or blocking the propagation of vibration. The effects of these two kinds of vibration reduction measures are good, especially for active vibration reduction. The measures taken are relatively sufficient, so the effect achieved is also good. If the flow rate is reduced by increasing the pipe passage, reducing the length of the elbow and the pipeline, increasing the radius of the elbow and reducing energy loss, etc., the purpose of vibration reduction can be effectively achieved. Or you can improve the processing technology to improve the processing accuracy of the parts of the meter pump, ensure the accuracy of the assembly, improve the bearing capacity of the melt pump, improve the lubrication state of the friction parts of the transmission end, etc., the Francium method is combined to achieve better The purpose of damping.
Of course, the passive damping effect of the melt pump is also good, but passive damping is used as an auxiliary to active damping, so the effect is not very obvious. However, with the combination of these two vibration reduction measures, the impact of vibration on the melt pump will become smaller, and there will be no problems such as inaccurate accuracy or difficulty in operation when used.
