The peristaltic pump is a positive displacement pump that can accurately pump solid, liquid and gas three types of substances. The peristaltic pump is mainly composed of pump head, hose and driver. The substance will be stored in the pump tube during transportation and will not come into contact with other parts.The peristaltic hose pump has many advantages: the peristaltic pump can run dry and will not damage the pump, even if the peristaltic hose pump has the accident, we should only replace the hose, and it will greatly reduce the peristaltic pump cost and improve the working effectiveness.

 Peristaltic pump flow refers to the volume of gas or liquid transported by the hose per unit time, which is the main basis for customers to choose the appropriate type of peristaltic pump.

 The main factors affecting peristaltic pump flow are speed, suction, etc.

 The rotation speed of the peristaltic pump refers to the rotation speed of the motor of the peristaltic pump, and refers to the number of turns of the motor in a unit time. The faster the rotations speed, the more materials transported. The flow rate of the peristaltic pump is proportional to the speed.

 The suction stroke of the peristaltic pump refers to the vertical height from the liquid level to the pump head of the peristaltic pump. The greater the suction range, the smaller the flow rate, which is inversely proportional to the suction range of the hose pump. Under the same suction lift, the density of the liquid also affects the flow rate. When the density is smaller, the flow rate will be greater..

 In addition, temperature, speed control error, head, hose pressure, hose manufacturing error, pump head manufacturing error and other factors will affect the accuracy of flow.

 The peristaltic pump is a positive displacement pump with metering function. The metering effect is mainly determined by the design principle of the peristaltic pump. The peristaltic pump uses rollers to squeeze the pump tube to achieve the transportation effect, so the accuracy depends on the inner diameter of the pump tube and the accuracy of the motor. The peristaltic pump has a good metering effect in a small flow range.

 The greater the flow rate of the peristaltic pump, the more material it pumps. Of course, if we want to choose a peristaltic pump with high delivery efficiency, we can also change the inner diameter of the hose. When we choose the inner diameter of the hose bigger, flow rate will be higher.
