In the experimental industry or pharmaceutical industry are inseparable from precision fluid transmission, and precision fluid transmission is commonly used is the flow peristaltic pump, today, Pruley fluid to explain what the pump is used for.

What is a flow peristaltic pump
Peristaltic pump is composed of pump head, drive and pump hose. Is to rely on the roller in the pump head to squeeze the fluid filled hose to transport the fluid, by alternately squeezing and releasing the elastic transport hose to pump the fluid. As the fingers move, negative pressure builds up inside the tube and the fluid moves along, like squeezing a hose with two fingers. A pillow fluid is formed by a hose between two rollers. The volume of the pillow depends on the inner diameter of the pump pipe and the geometry of the rotor. The flow rate depends on the product of three parameters: the speed of the pump head, the size of the pillow and the number of pillows produced by each turn of the rotor. Pillows are generally constant in size (except when pumping particularly viscous fluids).

Function and characteristics of flow peristaltic pump
Flow peristaltic pump is mainly used for various fluid precision transmission and filling. Because the pump is transmitted by hose (according to different liquids can be replaced by different materials of hose, easy to replace), it is mostly used for food industry and pharmaceutical industry with higher health level.

Application field of flow peristaltic pump: chemical industry; Mining and metallurgical industries; Laboratory industry; Paint industry; Food industry, etc.;

Flow peristaltic pump function introduction
1, color LCD display, touch screen plus button operation.

2, flow display, flow control, flow accumulation.

3. Expert system is convenient for users to use to a large extent.

4, can be low wheel spacing to achieve low pulse transmission, to ensure the flow of high precision, the card is equipped with a fine-tuning knob to adapt to the changes in the wall thickness of the flexible pipe, the flow between channels and output pressure can be fine-tuned.

5, external control high and low level control start and stop, positive and negative, simple separation, optical coupling isolation; External control analog volume to adjust the speed.

6, the internal structure adopts double-layer isolation design, the circuit board plus spray three anti-paint process, to achieve dust and moisture proof effect.

Notes on flow peristaltic pump
1, because the pump head is used to fix the hose and squeeze, so that it can transfer liquid, so the hose charge is jammed, not in the case of loose transmission.

2. The pump pipe may be damaged and cause liquid overflow. Please take necessary protective measures and check the pump pipe regularly.

3, Install and remove the external control device, please be sure to turn off the power to prevent damage to the equipment.

4. When connecting the external control or communication interface, please cut off the power.

5. Please connect the protective ground of the machine to the earth, otherwise there will be electric shock risk or electromagnetic interference.

The above is about the flow of peristaltic pump is used to explain, if you have any questions or need help, you can call the Pre fluid after-sales engineer.
