Considerations for peristaltic pump applied to on-line analytical instruments and water quality samplers

1.The material and pump pipe of micro peristaltic pump need to meet the requirements of relevant transportation,and the shell uses new solvent resistant materials.The control system must be stable and reliable,generally driven by stepper motor,need to pay attention to the problem of resonance point and excessive noise.When collecting sample liquid,the field working condition is if the head or time working time is long.

2.When equipped with micro peristaltic pump hose,you can choose a hose with thicker wall to reduce the speed of the driver,so as to improve the service life of the peristaltic pump hose and reduce the frequency of the maintenance hose.In the early stage of system development and life test,it is necessary to fully test,because many peristaltic pumps cannot see problems in the short term.If the materials are not solid and the design is defective,problems will be found only after long-term test.

3,the precision of peristaltic pump and supporting pump diameter and speed has a certain relationship,usually high speed of some pulse frequency will increase,but the peak pulse will be reduced,the natural period of transport will be more stable.Therefore,if there is a need for conveying smoothness,it is necessary to consider the relationship between increased speed and reduced pump life.

4,a good quality peristaltic pump is very able to improve the work efficiency of online analysis instruments,water quality sampler equipment,and product quality.The working suction range of micro peristaltic pump can reach 5-8 meters,and its working principle has the function of one-way valve and cut-off valve,which can effectively solve the problem of liquid backflow transmission.It is widely used in online analysis instruments and water quality sampling instruments and equipment.

5.Micro peristaltic pump adopts high-precision subdivision motor drive to accurately measure and sample,which can meet the requirements of online analytical instruments and water quality sampler,and accurate transmission and collection of test reagents and water quality samples.The life,resistance to organic solvents,high temperature and weather of peristaltic pumps and related accessories used in on-line analytical instruments and water quality samplers are very much in line with its requirements.Therefore,peristaltic pump is an important part of on-line analytical instrument and water quality sampler.
