Modeling of the linear peristaltic pump operation with the consideration of the pump’s operating element elastic properties
The article provides an overview of the main results of a comprehensive R&D program with the aim of development of scientific and methodological foundations for the substantiation and the engineering solutions for ensuring of workability of boiler feed pumps in extreme operating conditions. The operation of boiler feed pumps in thermal shock conditions is analyzed. The short-term modes of operation of boiler feed pumps in conditions of cutting off supplying of the cooling medium into the thermal barriers of pump, dry run of pump, above allowable working range of flowrate are discussed. Evaluation criteria for workability of boiler feed pumps in extreme operating conditions are suggested. The algorithms of developed design procedures and description of proposed engineering solutions are given.
