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, Puri fluid to explain to you what the pump is used for.

What is flow peristaltic pump The pump is composed of a pump head, a drive and a pump hose. It 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 in the tube and the fluid flows along with it, just 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 tube 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. The size of the pillow is generally constant (except when pumping fluids with particularly high viscosity).

Pump function and characteristics Pump is mainly used for various fluid precision transmission and filling. Because the pump is transmitted by hose (hose of different materials can be replaced according to different liquids, the replacement is simple and convenient), it is mostly used for food industry and pharmaceutical industry with higher health level.

Application: chemical industry; Mining and metallurgical industries; Laboratory industry; Paint and coating industry; Food industry; Flow peristaltic pump function introduction

1, color LCD display, touch screen plus button operation.

2, flow display, flow control, flow accumulation.

3. The expert system is convenient for users to use to a greater extent.

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

5, external control high and low level control start and stop, positive and negative, simple packaging, optocoupler isolation; External control analog 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.

Flow peristaltic pump precautions

1, because the pump head is used to fix the hose and extrude, so that it can transmit liquid, so the hose charge is stuck, not in the case of loose transmission.

2, the pump pipe may be damaged to cause liquid overflow, please take necessary protective measures, regularly check the pump pipe.

3, Install and remove the external control device, 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 supply.

5, please connect the protective ground of the machine with the ground, otherwise there will be the risk of electric shock or electromagnetic interference.

The above is the explanation of what the flow peristaltic pump is used for, if you do not understand or need help, you can call the Purui Fluid after-sales engineer.
