Description
Technical Parameters
High volume peristaltic pump, instrument equipment, peistaltic pump consists of three parts: driver, pump head, and hose. The main competitive advantages of peistaltic pumps are that the fluid is isolated in the pump tube, the pump tube can be quickly replaced, the fluid can flow in reverse, it can operate dry, and the maintenance cost is low. A peistaltic pump is like squeezing a fluid filled hose with your fingers, and the fluid inside the hose moves forward as your fingers slide forward. The principle of peistaltic pump is also the same, except that the fingers are replaced by rollers. Pump fluid by alternately squeezing and releasing the elastic delivery hose of the pmp. Just like squeezing a hose with two fingers, as the fingers move, negative pressure is formed inside the hose, and the liquid flows accordingly. Due to its unique working principle and advantages, it has a wide range of applications in multiple fields. For example, in the field of biomedicine, peistaltic pumps are used for drug delivery, cell culture, etc; In the field of chemical engineering, it is used for the transportation of corrosive liquids; In the food industry, it is used for filling fruit juice, jam and other fruit containing liquids; In the field of environmental protection, it is used for wastewater treatment, etc.
Working Principle
A peistaltic pump is like squeezing a fluid filled hose with your fingers, and the fluid inside the hose moves forward as your fingers slide forward. The principle of peistaltic pmp is also the same, except that the fingers are replaced by rollers. Pump fluid by alternately squeezing and releasing the elastic delivery hose of the pmp. Just like squeezing a hose with two fingers, as the fingers move, negative pressure is formed inside the hose, and the liquid flows accordingly.
High volume peristaltic pump is a pump tube that forms a "pillow" shaped fluid between two rotating rollers. The volume of the pillow depends on the inner diameter of the pmp tube and the geometric characteristics of the rotor. The flow rate depends on the product of three parameters: the speed of the pmp head, the size of the "pillow", and the number of "pillows" generated by each rotation of the rotor. The size of the pillow is generally a constant (except when pumping fluids with particularly high viscosity).
Compared to pumps with the same rotor diameter, pmps that produce a larger "pillow" volume also have a larger volume of fluid transported per revolution of the rotor, but also generate greater pulsation. This is similar to the situation of membrane valves. The pmp that produces a smaller "pillow" volume also delivers a smaller volume of fluid per revolution of its rotor; Moreover, the small "pillows" formed quickly and continuously make the fluid flow smoother. This is similar to the working mode of gear pumps.

Maintenance And Upkeep
Maintenance is crucial for ensuring the long-term stable operation and extending the service life of peistaltic pumps. Here are some basic maintenance steps:
Regularly check the hose:
Hoses are the main consumables of peistaltic pmps and should be regularly inspected for wear, cracks, or expansion.
Once the hose is found to be damaged or aged, it should be replaced immediately to avoid fluid leakage and a decrease in flow rate.
Clean the hose and pump head:
Regularly clean the inside and outside of the hose and pmp head according to the nature of the conveyed liquid to remove residue and prevent contamination or blockage.
Appropriate cleaning agents and tools should be used during cleaning to avoid damage to hoses and pmp heads.
Check the wear of the rollers:
The roller directly acts on the hose and may wear out after long-term use.
Regularly check the smoothness and shape of the roller surface, and replace it if necessary to ensure good squeezing effect and reduce hose damage.
Electrical maintenance:
If using an electric peistaltic pmp, regularly check whether the power cord, plug, and controller are intact to avoid moisture and physical damage.
Ensure that the control system and display interface are clean and dust-free to avoid affecting the pmp's performance and accuracy.
Lubrication:
For peistaltic pumps with mechanical moving parts (such as roller bearings), regularly add lubricating oil according to the instructions to reduce wear and maintain smooth operation.
When lubricating, appropriate lubricating oil and lubrication method should be selected to avoid negative effects on the performance and service life of the pmp.
Storage conditions:
When not in use, the peistaltic pump should be stored in a dry, non corrosive gas environment to avoid prolonged compression of the hose.
When storing, the pmp head should be disassembled, other liquids inside the pmp body should be wiped dry, and lubricating oil should be fully filled in the relevant connection parts to prevent rust or damage to the pmp head and drive components.
Record maintenance:
Establish maintenance records, including hose replacement time, cleaning records, abnormal situations, and handling measures.
Maintenance records help track the maintenance history of pmps and provide reference and basis for future maintenance.
By implementing the above maintenance steps, the long-term stable operation and extended service life of the perstaltic pmp can be ensured. At the same time, it can also improve the working efficiency and performance of high volume peristaltic pumps.
