Filling machineSuperiority
1. No pollution: the fluid only touches the pump tube, not the pump body;
2. High precision: repeatability, high stability and precision;
3. Low shear force: an ideal tool for conveying shear-sensitive and aggressive fluids;
4. Good airtightness: good self-priming ability, idling and preventing backflow;
5. Simple maintenance: no valves and seals;
6. It has the same two-way flow delivery capacity; it will not cause any damage to any parts of the pump when there is no liquid and dry operation; it can produce up to 98% vacuum; there is no valve, mechanical seal and packing seal device, so there will be no leakage And maintenance factors; it can easily transport solid, liquid or gas-liquid mixed phase fluids, allowing the diameter of the solid contained in the fluid to reach 40% of the inner diameter of the tubular element; it can transport all kinds of materials with abrasive, corrosive, and oxygen sensitive characteristics and various Food, etc.; only the hose is a component that needs to be replaced, and the replacement operation is extremely simple; except for the hose, the conveyed product does not contact any components.limitations
1. Pressure limitation: The use of flexible pipes will limit the pressure.
2. When the pump is operating, a pulse flow is generated,
The solution is:
1. Increase the number of rollers, the flow will decrease
2. Use the pulse suppressor: The pulse suppressor is a simple positioning container. The working principle is that air is more compressible than liquid. The pulse flow enters the container, and the air bag on the liquid sinks to absorb the pulse and then flows out smoothly
3. The flow rate changes with time and will decay. (Due to hose wear)
The outlet pressure of the pump has certain limitations, generally not more than 0.3MPa, usually between 0.1-0.2MPa.
