Encountered in normal use industrial peristaltic pump,the output flow rate of high and low pulse is not very stable,eliminate some of the pump head,pump pipe and drive some intuitive reasons,there is also a easy to ignore,is the industrial peristaltic pump transmission liquid,liquid liquid viscosity,head,the nature of the liquid,the impact on the traffic.

Liquid fluid viscosity in peristaltic selection,is relatively easy to ignore the details,strong acid and strong base,liquid viscosity,when the liquid viscosity reaches a certain value,because of the hose suction capacity is limited,pumping efficiency will be reduced.At the same pump speed,the flow of the viscous liquid will be smaller than that of the water pump.The higher the viscosity,the more the flow will decrease.

Industrial peristaltic pump in fluid transmission ability at the same time,also has the self-priming ability,in theory,under the same atmospheric pressure,the transmission can reach 10 m or so,but in the actual circumstances of peristaltic pump flow will be attenuation,and each one meter,suction peristaltic pump flow will decay by about 15%,if the demand for a high suction,can choose more inner diameter,Thicker wall hoses and higher rev drives are selected.

Hoses of different materials and specifications have different service life.Choose a hose suitable for the service life according to the service situation.PharmedBPT tube relative to domestic silicone tube long life,air tightness will be better.For example,when doing anaerobic bacteria culture experiment,the air tightness of the pump tube is very important,which can prevent the outside oxygen from entering the culture bacteria through the pipeline.

In addition to the chemical compatibility and life of the pump tube is better than the domestic silicone tube,the hardness will be higher.Therefore,when selecting the pump tube and the driver,the influence of the hardness of the pump tube on the driver should also be considered.If the driver torque selected is too small,it may not pressure the pump tube.
