What precautions are required for peristaltic pumps for on-line analytical instruments and water samplers?

The peristaltic pump has a self-priming capacity of 5-8 meters and has the function of a one-way valve stop valve. It is widely used in water sampling instruments and online analytical instruments. The products, also known as constant flow pumps and peristaltic pumps, can be accurately metered and sampled to meet the accurate collection and delivery of reagents such as water samples and test reagents by water samplers and online analytical instruments.

Inonen peristaltic pump can provide users with a full range of peristaltic pump products and supporting solutions, which can provide customers with rapid system development and integration solutions and solutions, saving customers' development and application cycles and saving costs.

Online analytical instruments and water sampling instruments as a highly automated and unattended monitoring instrument usually require all the original devices to ensure long-term stable and reliable operation, can withstand high temperature, high temperature, organic solvents and other polluted environments, so creep Pumps and related accessories have very high requirements for life, organic solvents, high temperature and weather resistance. Therefore, the application of the peristaltic pump to the on-line analytical instrument and the water sampler requires attention to the following:

1, the Material of the constant flow pump and the peristaltic pump and the pump tube need to meet the relevant transportation requirements, and the pump casing uses a new solvent-resistant material.

2, the constant current pump and peristaltic pump control system should be as stable and reliable as possible, usually using stepper motor drive, but need to pay attention to control the common shock point to prevent excessive noise.

3, constant flow pump and peristaltic pump to collect sample liquid If there is a certain head and sampling time working time is long, need to pay attention to the use of thicker wall pump tube while allowing the pump to work at a lower speed to improve the service life of the pump tube Reduce the frequency of maintenance changes.

4, in the early stage of system development and life testing must be fully tested, because many peristaltic pumps can not see problems in the short term, peristaltic pumps with unfair materials and defective design can only find problems during long-term testing.

5, the accuracy of the constant flow pump and the peristaltic pump and the matching pump tube diameter and the rotational speed have a certain relationship, usually the high frequency of some pulses will increase the frequency, but the peak of the pulsation will be reduced, the natural period will be more stable. Therefore, if there is a need for smoothness of delivery, then the relationship between the increase in speed and the decrease in pump life should be considered and balanced.
