Peristaltic pump through the flexible delivery hose pump alternating squeezing and releasing for pumping fluid. As two fingers, like the squeeze tube, with the finger movement, the formation of vacuum tube, the liquid flows along. Peristaltic pump roller is transferred between the Oil pumpstwo section of tubing form a "pillow" shape of fluid. "Pillow" the size depends on the pump tube diameter and the rotor geometry. Flow rate depends on the pump head speed with the "pillow" the size of a circle generated by the rotor per revolution "pillow" and the product of the number of these three parameters. "Pillow" the size is generally constant (pumping viscous fluid particularly when the exception). Take the rotor diameter, compared to the same pump to produce a larger, "Pillow" fire pumpsvolume pump, its circle of the rotor per revolution is also a larger volume of fluid delivered, but also produced a larger degree of fluctuation. This is similar to the situation with the membrane valve. Arising from small "pillow" volume pump, its circle of the rotor per revolution is also a smaller volume of fluid delivered; Moreover, rapid and continuous formation of small "pillow" so that the fluid flow is more stable. This is similar to the situation with the gear pump. The same flow rate with a two-way transmission capacity; without liquid air under the conditions of operation will not damage any component of the pump; can produce up to 98% of the vacuum degree; no valves, mechanical seals and packing seals, there is no leakage and maintenance of Split case pumpsthese produce factors; be able to easily transport solid, liquid or gas-liquid mixed phase flow, allowing flow of the body solids diameter tubular element diameter of 40%; can transport all kinds with a grinding, corrosion, oxygen-sensitive properties of materials and variety of food and other ; only a hose as in need of replacement parts, replacement operation itremely ; In addition to hose things, the transportation products do not contact with any components.
