Characteristics of high performance parallel connected sewage pumps

The peculiarity of the operation of sewer systems is the unevenness of their load. For example, in the system of housing and communal services allocated daily unevenness. Therefore, the actual task is the operation of the system with different volumes of pumped liquid while ensuring high efficiency. The computer calculation of load characteristics at parallel connection of sewer pumps of high productivity is considered. The dependence of the pumped liquid volume, power, efficiency are presented. from the supply of two pumps in parallel connection. Similar characteristics are constructed for three parallel connected pumps. Change of efficiency is investigated. for systems with different number of connected pumps. The high efficiency of the systems functioning with the possibility of varying the number of connected pumps is shown.
