LINEAR PERISTALTIC PUMP

摘要

The invention pertans to pumping via pipes of highly viscous fluids, abrasive and paste like as well as chemically highly reactive materials. Linear peristaltic pump offered consists of elastic pipe (1) and at least four chambers (2) covering the pipe that is fulfilled by working media (fluid or gas) that is aimed to deform the pipe. The pump (9)in its work is creating pressure or vacuum in chambers (2) fulfilled by the working media and is pumping this media in or out. Pressure or vacuum valves (5, 6) are linked to the outputs of the pump. Each valve has one co-axial input-output channel and four mutually orthogonal output-input channels (7, 8). These input-output channels are sequently linked with chambers (2) which are distorting the pipe (1). Each valve has a rotor that is rotating synchronously with the channel connecting valve's coaxial channel, and it during rotation is being sequently connected with the output channel of each chamber. The pump (9) during its operation sequently is creating a pressure in one of chambers (2) and vacuum in another one, at the same moment keeping constant pressure in two other chambers, in such a way squeezing pumping media through the pump.
