Structure Analyses and Flow Rate Model of Peristaltic Pump of Cement Foaming Machine

Abstract

Abstract. With the constant development in the fields of Greenness, Environmental Protection and Energy Conservation all over the world, the improvement of foam cement technology is to bring about a revolution in the architectural material industry. The main component of the cement foaming machine is the delivery pump system, in which the peristaltic pump is the most important part. In this thesis, on the bases of study of peristaltic pump in imported machines, mathematical models are made and an approximate calculation of flow rate of the peristaltic pump is given through exhaustive analyses of the structure and the changes in the cross section before and after compression rolling. This research will also make it possible to analyze the pressure in the exit of the pump and deduce the power needed by the driven peristaltic pump according to the factors like the calculation of on-way pressure loss with the consideration of working altitude. This research is expected to provide a theoretic principle for the development of cement foaming technology.

Investigation of Pressure Variations in Hose Pumps under Different Flow Regimes Using Bidirectional Fluid–Structure Interaction

“…Hose pumps, also known as peristaltic pumps, represent a distinct category within positive displacement pumps [1]. They find extensive applications across a wide range of engineering fields, including wastewater treatment, chemical industries, food production, brewing, sugar manufacturing, paper and ceramics industries, construction, and mining [2][3][4][5][6]. As a complex engineering apparatus, a hose pump comprises critical components such as the pump casing, hose, squeezing rollers, couplings, and an electric motor.…”
