The composition and performance of peristaltic pump
The peristaltic pump is a pump tube that forms a "pillow" fluid between the two rollers. The volume of the "pillow" depends on the inner diameter of the pump tube and the geometry of the rotor. The flow depends on the speed of the pump head and the size of the "pillow", and the number of "pillows" generated by the rotor. The size of the "pillow" is generally constant (except when pumping fluid with a particularly large viscosity).
The peristaltic pump consists of three parts: the drive, the pump head and the hose. The fluid is isolated in the pump tubing, which can quickly replace the pump tubing, the fluid retrograde, can dry run, the maintenance cost is low, and so on constitute the main competitive advantage of the peristaltic pump.
1, no pollution: fluid only contact the pump tube, do not touch the pump;
2, high precision: repeat accuracy, high stability;
3, low shear force: is the ideal tool for conveying shear sensitive, aggressive and strong fluid;
4, good sealing: a good self-priming ability, can be idle, to prevent the return;
5, simple maintenance: no valves and seals;
6, with two-way equal flow capacity; no liquid air operation will not damage any parts of the pump; can produce up to 98% vacuum; no valves, mechanical seals and packing seals, there is no such leakage And the maintenance of factors; can easily transport solid, liquid or gas-liquid mixed phase fluid, allowing the fluid contained in the solid diameter of 40% of the diameter of the tubular components; can transport a variety of grinding, corrosion, oxygen sensitive properties of materials and various Food, etc .; only the hose for the need to replace the parts, the replacement operation is extremely simple; in addition to the hose, the delivery of products without contact with any parts.
