The multi-channel peristaltic pump is to install the hose between the rotor and the stator to achieve the purpose of pumping. However, we are using stable motors, standard pump heads and modern control technology. During work, a section of the pump tube between the two rollers forms a pump chamber. The size of the pump chamber depends on the inner diameter of the pump tube and the size of the rotor. The theoretical flow is the product of the volume of the pump chamber, the number of pump chambers in 360°, and the pump speed. Compared with a pump with the same rotation diameter, a pump with a larger pump chamber has a larger volume of fluid delivered by the rotor per revolution, but also a larger pulse. On the contrary, a pump with a smaller pump chamber has a smaller volume of fluid delivered per revolution of the rotor, but also produces smaller pulses, but rapid and continuous pumping can ideally reduce the pulses. Therefore, in In some occasions with small flow and very small pulse requirements, the selection of the pump head of the multi-channel peristaltic pump is very critical.
Multi-channel peristaltic pump use skills:
1. For the newly received multi-channel peristaltic pump, let it stand for 3-5 hours before testing. Before the test, check whether the appearance of the peristaltic pump is damaged, and then perform the test according to the instruction manual after confirmation.
2. The multi-channel peristaltic pump should not be used outdoors as much as possible. If it must be used outdoors, there is a box or other things to shield it from rain, which can effectively extend the life of the peristaltic pump
3. When you take out the peristaltic pump that has not been used for a long time, please add a certain amount of oil to the inner shaft of the pump head. The oil here can be anything, mainly for lubrication.
4. Every time the pump tube is pressed into the pump head of the peristaltic pump, the pump tube can be properly pulled to the left and right, which can effectively improve the accuracy
5. For multi-channel peristaltic pump products, how to reduce the error between channels? After doing the above step, adjust the length of the left and right sides of the pump head of each channel to be consistent
6. Multi-channel peristaltic pump shows that the number of revolutions is always changing. The reason may be that there is some magnetic interference around the pump. You can restart the pump and put it elsewhere to test whether the same problem still exists.
The advantages of multi-channel peristaltic pump: high cleanliness and no pollution: the liquid only touches the hose, which is convenient for cleaning. It only takes a few seconds to replace the hose. Low energy consumption: self-priming and one-way valve capability. High precision: the accuracy of sub-packaging and reproduction can reach 1% to 0.5%. Low shear: It can pump shear-sensitive liquids and organic solvents, and can transport solid fluids. Low maintenance: quick connection, no valves and seals, the hose is the most vulnerable part.
Multi-channel peristaltic pump lubrication and maintenance attention: check the tightness of the side guide roller when filling the oil, if it is found to be too loose, tighten it with sharp-nose pliers. Should consider the wear of the inner bearing of the side guide roller, which can be removed and replaced or replaced by the side guide roller.
