In the transmission of solid-liquid mixture pumps, peristaltic pump is one of them, but the peristaltic pump transmission solid-liquid mixture is limited in scope, and some use should pay attention to the problem.
The solid components contained in the solid and liquid mixture can be divided into two kinds: hard particles and flexible particles.
When the solid-liquid mixture transmission with hard particles, if the proportion of hard particles is relatively large, easy to deposit, with a peristaltic pump transmission time should be run with higher speed, because this kind of mixture is the most easily in the peristaltic pump inlet pipe at the accumulation, causing blockage. It is necessary to install the agitator in the container with solid liquid mixture to ensure that the solid particles do not precipitate and distribute evenly. In addition, there is a limit on the diameter of the hard solid particles. The maximum diameter of the particles is not more than 10% of the diameter of the hose. When the transmission of solid particles of uniform size, it is best to choose a thicker pipe, so that the particle diameter is less than 5% of the inner diameter of the tube or lower proportion, otherwise, there is the possibility of solid particles stuck in the pump head.
When the transfer of flexible particles with the solid-liquid mixture, under normal circumstances, the proportion of flexible particles is relatively small, the whole was milky way, not easy to deposit, so the peristaltic pump can run at a lower speed. Under normal circumstances, the mixing container is also needed to ensure the uniform distribution of soft particles. The diameter of the flexible particle size requirements are relatively loose, the maximum diameter of the largest particles can not exceed 30% of the inner diameter of the hose. When the particle size of flexible transmission is more uniform, the best selection of thick tube, the particle diameter is smaller than the inner diameter of the hose 15% or lower proportion, otherwise, the pump head can be destructive or squeeze hose is blocked on flexible flexible particles particles, causing poor transmission.
