The peristaltic pump is a "pillow" fluid formed by a section of the pump between the two rollers. The volume of the pillow depends on the inner diameter of the pump tube and the geometric characteristics of the rotor. The flow rate depends on the product of the pump head speed and the size of the "sleeper" and the number of "sleepers" produced by each turn of the rotor. The size of the pillow is usually constant (except when the fluid is particularly viscous).

Comparing with the pump with the same rotor diameter, the pump with a larger "pillow" volume is produced, and the volume of fluid transferred by the rotor per turn is larger, but the pulsation is also larger. This is similar to the case of membrane valves. A pump with a smaller "pillow" volume is produced, and the volume of fluid transferred by the rotor per turn is smaller; moreover, a small "pillow" formed rapidly and continuously makes the fluid flow more stable. This is similar to the working mode of gear pumps.

Superiority

1, no pollution: the fluid only contacts the pump tube and does not touch the pump body.

2. High accuracy: repeatability and accuracy.

3. Low shear force: an ideal tool for transporting shear sensitive and aggressive fluids.

4, good sealing performance: good self suction ability, can be idle, can prevent backflow;

5, simple maintenance: no valves and seals.

6. It has the capacity of two-way equal flow transportation; it can not cause damage to any parts of the pump without liquid empty operation; it can produce up to 98% vacuum degree; without valve, mechanical seal and packing sealing device, it will not have these factors of leakage and maintenance; it can easily transport solid, liquid or gas-liquid mixed phase fluid, allowing fluid The diameter of the solid contained in the pipe is 40% of the inner diameter of the tubular element; it can transport all kinds of materials with grinding, corrosion, oxygen-sensitive characteristics and various foods; only the hose is the part to be replaced, the replacement operation is extremely simple; except the hose, the product conveyed is not in contact with any parts.

Pharmaceutical applications: Peristaltic pump in the pharmaceutical industry is mainly used in the pharmaceutical coating granulation and pharmaceutical sub-loading. Spray drying granulator is also called drying granulator and fluidized bed granulator. It is used to spray special sugar coating on the surface of various instant granules and form granules after drying. The specific drying heat source of these granulators can play the purpose of evaporating water, but the relationship between water evaporation and particle formation is dynamic, so it is necessary to spray the liquid and moisture content to be very precise, to ensure a certain humidity of the particles so as to facilitate the perfect formation of particles.
