What is the difference between the pump and the peristaltic pump? The use scenarios of the two are different. If you need to fill a pool, or irrigate a large cubed storage tank, they are both pumps to use, and their main application is efficiency. On the contrary, in some industries, such as laboratories, pharmaceuticals, medical peristaltic pumps, etc., it is a small flow, accurate transmission, and the main use of precision.
Peristaltic Pump (Peristaltic Pump), also known as constant flow pump, is a new type of industrial pump, is the product of modern industrial development, widely used in pharmaceutical, food, chemical and other industries, transport some sensitive, viscous, corrosive, high grinding effect, high purity requirements, containing a certain particle material medium.
Hose is a peristaltic pump to connect the liquid elements, the pump through the roller or press block to squeeze the hose work. This means that the pump can dry rotate, self-priming and handle high viscosity, high wear media. In addition, the hose acts as an independent unit, so that the pump body does not need to be sealed, so it is completely leak-free and very hygienic. Each rotation output a fixed flow rate, making peristaltic pump quantitative feed applications with excellent performance. This principle can be applied to all peristaltic pumps, so the pump head and drive part are important factors to distinguish the quality of peristaltic pumps. Peristaltic pump is the principle and concept of a hose pump
Just as repeated muscle contractions and relaxations allow blood to flow through blood vessels, peristaltic pumps work by relying on the pumping efficiency produced by alternating squeezing/releasing of several rollers along an elastic tube. The extruded fluid in the pipe produces a flow output. When the pressure disappears, the volume increases as the pipe returns to its original state by relying on its own elasticity, creating a vacuum and sucking in fluid. This continuous action is the working principle of peristaltic pump.
Peristaltic pumps pump fluid by alternately squeezing and releasing the pump's elastic delivery hose. Just like squeezing a hose with two fingers, as the fingers move, negative pressure forms inside the pipe and the liquid flows. Peristaltic pump is a pump tube "pillow" shaped fluid formed between two rollers. The "pillow" volume depends on the inner diameter of the pump tube and the geometry of the rotor. The flow rate depends on the product of the three parameters of the speed of the pump head and the size of the "pillow" generated by each turn of the rotor. The "pillow" size is generally constant (except when pumping fluids with particularly high viscosity). Compared with pumps with the same rotor diameter, a larger "pillow" is produced for volume pumps, the volume of fluid transported by the rotor per turn is also larger, but the pulsation is also larger. This is similar to the case of membrane valves. The volume of flow transported by the smaller "pillow" rotor is also smaller at each turn. Moreover, small pump "pillows" formed in rapid succession make the fluid flow more stable. Similar to gear pump.
With the same two-way flow capacity; Liquid free air operation will not damage any parts of the pump; Can produce 98% vacuum degree; No valves, mechanical seals and packing seals, no leakage and maintenance factors; It can easily transport solid, liquid or gas-liquid mixed phase fluid, allowing the solid diameter in the fluid to reach 40% of the inner diameter of the tube; Can transport a variety of grinding, corrosion, oxygen sensitive materials and food; Only the hose is the part that needs to be replaced, and the replacement operation is very simple; The product does not touch any parts except the hose.
