Filling machine(1) Advantages
1, no pollution: the fluid only contact the pump pipe, do not contact the pump body;
2. High accuracy: high repeatability and stability accuracy;
3. Low shear force: It is an ideal tool for conveying shear sensitive and erosive fluids;
4, good sealing: with good self-priming ability, can idling, can prevent backflow;
5. Simple maintenance: no valves or seals;
6. With two-way transport capacity of the same flow;
No liquid empty operation will not cause damage to any parts of the pump;
Up to 98% vacuum;
There are no valves, mechanical seals and packing seals, so there are 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 tubular part;
Can transport a variety of grinding, corrosion, oxygen sensitive properties of materials and a variety of food;
Only the hose for the parts that need to be replaced, the replacement operation is very simple;
The delivered product does not come into contact with any parts except hoses.
(2) Disadvantages
1. Pressure limitation: The use of flexible pipe will limit the pressure bearing.
2, the pump in operation will produce a pulse flow.
The solution:
(1) Increase the number of rollers, the flow will decrease.
(2) The use of pulse suppressor: the pulse suppressor is a simple positioning vessel, the working principle is because the air is more compressible than the liquid, the pulse flow into the container, the air bag on the liquid sink absorption pulse and then gently outflow pulse suppressor.
3. The flow rate will decrease with time.
(due to hose wear)
The outlet pressure of the pump has certain limitations, generally does not exceed 0.3MPa, usually between 0.1 and 0.2MPa.
Peristaltic pump principle, classification and advantages and disadvantages are introduced here, peristaltic pump system is suitable for laboratory, industrial manufacturing and field applications.
The design used restricts the fluid to the pump tube because the pump does not contaminate the fluid and the fluid does not contaminate the pump.
Peristaltic pump has the advantages of durability, no pollution, easy cleaning, low maintenance and so on, in the hose pump market in a leading position.
