How to Set Peristaltic Pump Flow Rate?

1. The peristaltic pumps' peristaltic pump flow rate

Peristaltic pumps are more commonly used in precision instruments. Some customers use the pumps for the first time, and they are not very good at the operation, then the following will explain how to set peristaltic pump flow rate.

 

2. How to set peristaltic pump flow rate

(1) Inquire according to the flow parameter table

 

You can refer to the Hose Flow Reference Table to directly get the speed corresponding to the flow according to the pump head and hose model, or you can check the amount of liquid transferred in each turn, calculate the speed corresponding to the required flow according to the flow calculation formula, and then adjust the speed to get the corresponding flow. This method can roughly set the speed and dispensing peristaltic pump flow rate easily, so it is commonly used in speed control type peristaltic pumps.

 

(2) Calculate the corresponding relationship between speed and peristaltic pump flow rate

 

Set arbitrary speed as n1, and measure the actual liquid quantity Q1 transferred in a certain time t1.

 

Calculate the flow coefficient according to a=Q1/ n1, next, calculate the required speed n2 according to the formula n2 =Q2 / a, then adjust the speed to get the required flow L1.

 

The flow accuracy obtained by this method is higher, but the operation is complex, and it is suitable for "speed regulating pumps" which require higher flow and quantitative accuracy. When the external working conditions change or it runs for a long time, it is necessary to carry out flow correction in time to maintain a high flow accuracy.

 

(3) Direct input of flow parameters

 

General intelligent flow peristaltic pumps and distribution peristaltic pumps adopt high-definition LCD touch screens for display and operation. You can simply select the pump head and hose model, and then directly input the flow parameters.

 

The flow rate obtained by this method is of high accuracy and can be completed only according to the prompts. It is convenient to operate and highly intelligent. The pump forms a closed-loop system with the flow sensor to realize automatic real-time flow correction and long-term stable flow transmission.

 

Nanjing Runze Fluid Control Equipment Co., LTD. can provide you with high flow peristaltic pumps, low flow peristaltic pumps, and other fluid control equipment. You can select the appropriate peristaltic pump after mastering the required peristaltic pump flow value.
