What are the factors that affect the flow rate of peristaltic pump hose peristaltic pump?

Now I believe we should all understand that the peristaltic pump has flow, so do you know what factors affect the flow of peristaltic pump? Now please follow the peristaltic pump flow small series to understand it.

1. The flow rate refers to the volume of gas or liquid flowing through peristaltic pump in unit time, which is usually expressed in "ml / min", "UL / min" and "L / min"【 1L=1000mL,1mL=1000uL]

2. Speed refers to the running speed of peristaltic pump motor, with the number of revolutions per unit time as the unit of measurement, usually "RPM" or "RPM" as the unit.

The reason is that the flow rate and speed are generally proportional, but there are also special cases, which can not be generalized.

3. Suction head refers to the vertical distance from the head of peristaltic pump to the liquid plane.

The size of suction head affects the flow rate. The larger the suction head is, the smaller the flow is. When the flow reaches a certain value, the pump will not produce liquid.

Under the same suction head, the liquid density also affects the flow rate. The smaller the density is, the greater the flow rate is.
