Assessment of the degree of influence of the solid phase of mine wateron the durability of the hydraulic foot assembly of the sectional pump of the main drainage plant of the Udachny mine

Introduction. The main factors, which negatively influence on durability of balancing ring sectional pump, are presented. Object study. pumps the dewatering facilities kimberlite mine “Udachny”. purpose research. Assessment waters solid phase degree pump to clarify expected technical and economic effect penetration an additional clarifying tank in conditions drainage Research methodology.The results inspections failed rings allowed establish types their damage. Next, according analytical researches factors were determined, accompanied with loss operability ring. Then, help correlation regression analysis each was estimated. results. According visual inspection, hydroabrasive wear is most strongly manifested places contact friction parts unit.It has been found that life unit smooth start a separately taken water plant can be calculated as linear function conditional intensity hydro-abrasive-adhesive its parts, product concentration mechanical impurities resistance coefficient metal, takes into account total operating time transient modes. In underground development ores, service primarily determined by pressure developed pump. At “Udachny” PJSC ALROSA, where there maximum under drainage, reservoir driven useful volume, significantly exceeds water-collecting mining workings.The inclusion this current process chain for will reduce content them, theory should positively affect components flow part pumping equipment, including unit.
