Cause analysis and treatment of high vibration value of washing water pump in methanol to olefin plant
Aiming at the problem of excessive vibration of washing water pump in methanol to olefin plant(MTO)during the test run,the factors affecting pump vibration were analyzed step by step through a series of measures such as eliminating the grouting defect of pump base,retesting the alignment of pump coupling,checking the support and connection stress of pipeline,adjusting and modifying the filter.Based on the installation and structural parameters of the pump inlet filter,the effective filter area was calculated quantitatively.Combined with the analysis of test data,it was found that the insufficient effective filtering area of the filter was an important factor affecting the suction flow of the pump and leading to the increase of pump vibration.Through the transformation of the filter cartridge,the influence of fluid resistance,drift and eddy current was reduced,the fluid flux was increased,and the vibration state of the pump was greatly improved.
