Abstract

Practice shows that in the conditions of gold mining enterprises in Yakutia, the MTBF of double-acting pumps is relatively small and can be no more than 100 motor hours. Emergency downtime caused by the repair of pumping equipment is highly undesirable, since they negatively affect the safety of mining operations, as well as the technical and economic performance of the gold mining enterprise. The purpose of this research work is to establish the reasons for the low operational reliability of double-acting pumps during open development of gold-bearing deposits in Yakutia, as well as to establish the most optimal technical solution to improve the efficiency of pumping equipment under specified operating conditions.
