As peristaltic pump plays an increasingly important role in the national economy, people pay more attention to peristaltic pump. Let's learn about the selection of peristaltic pump should pay attention to which aspects of the problem.

1. Select the tube

As a peristaltic pump hose conditions have a certain elasticity, that is, the hose can quickly recover shape after radial pressure, has a certain wear resistance, has a certain ability to encounter pressure, no leakage (good air tightness), low adsorption, good temperature resistance, not easy to aging, no swelling, corrosion resistance, advanced precipitate.

2, select the pump head

Whether it is easy to replace the hose or fix the hose pressure pipe gap by ratchet or other ways to adapt to the hose with different wall thickness or to achieve the fine adjustment of the pressure roller selection: 6 roller structure relative flow is slightly larger; 10 Roller structure fluid pulsation amplitude is small whether the trigger structure is dexterous, open the card is convenient.

3. Select the drive

Whether flow control is needed, whether liquid volume distribution is needed, what is the size of flow range, whether the overall structure is reasonable, whether the operation is convenient, whether flow accuracy and liquid volume accuracy meet the requirements

Special requirements: protection grade, explosion-proof grade, etc. External control requirements: equipment matching, operation mode, etc.

Advantages of peristaltic pump:

1, no pollution: fluid only contact the pump pipe, do not contact the pump body;

2, high accuracy: repeat accuracy, high stability accuracy;

3. Low shear force: it is the dream tool for transporting shear sensitive and erosive fluid;

4, good sealing: has good self-priming ability, can idling, can prevent reflux;

5, the cover is simple: no valves and seals;

Peristaltic pump disadvantages:

1, pressure limitation: with flexible pipe, will make the encounter pressure is limited;

2, the pump will attack a pulse flow in operation;

3, the peristaltic pump by adjusting the speed and changing the inner diameter of the pump pipe to reach the change of flow, flow range of the peristaltic pump is narrow;

Peristaltic pump can transport a variety of grinding, erosion, oxygen sensitive characteristics of the material and a variety of food, only the hose for the replacement of parts, replacement operation is very simple, in addition to the hose, the delivery of products do not contact with any parts. When the user chooses, if the advantages and disadvantages of peristaltic pump to do more phase cooked, will be of great help to the selection of peristaltic pump.
