Three small details of centrifugal sand pump overhaul

a) When use a new sand pump or the mechanical seal is changed newly, keep the packing bushing in relexed state to avoid wearing out the antiwear sleeve prematurely.
b) After working one year,and the mechanical seal fails,the pump is sealed by packings by compressing the packing bushing with the holdingdown bolt.When the packing bushing fails to adjust,add a packing(packing section is 12mm×12mm).
c) After shaft sleeve antiwear layer wears out, change the mechanical seal and shaft sleeve in time.
