The pump tube is one of the important components of a peristaltic pump, and the end user often misplaces the tubing, making it unsuitable for the desired application. Some users even use ordinary pipes instead of peristaltic pump tubes, causing disastrous consequences. With the increasing number of pump tubes on the market, it is also difficult to select pump tubes.
Peristaltic pumps are becoming increasingly popular due to their pollution-free pumping characteristics and the need for less maintenance. However, when designing or purchasing a peristaltic pump system, many engineers often overlook an important component, the pump tube of a peristaltic pump.
Chemical compatibility:
The pipe must be chemically compatible with the fluid to be pumped in order to have good pumping performance and safety performance. With the increasing number of tubing on the market - some peristaltic pump models have up to 15 available tubing - so users can always find a suitable tubing that is chemically compatible with a particular fluid.
Many pump tube suppliers offer chemical compatibility tables. However, engineers should be aware that chemical compatibility tables specific to pump tubing should be used instead of chemical compatibility tables for common tubing. Because ordinary pipes have only general contact with chemicals, and peristaltic pump tubes are in contact with chemical fluids under pressure conditions, the chemical compatibility level of ordinary pipes cannot be equal to the chemical compatibility level of peristaltic pump tubes. Therefore, only the pump tube should be referred to, not the chemical compatibility level of the general pipeline and related materials, otherwise the pump tube will be ineffective or damaged and leaked, resulting in damage or dangerous accident of the pump.
When referring to the chemical compatibility table, the end user should take each component of the solution, not just the main component, for compatibility check with the pipe to be used. Some acids or solvents can cause enough damage to the pump tube even after being in contact with the pump tube for hours or days, even if it is only trace amounts. The end user should check each chemical in the solution to ensure it is compatible with the selected pump tubing.
Also keep in mind that the chemical resistance of the pump tubing decreases with increasing temperature. Some chemicals do not affect the pump tube at room temperature, but when the temperature rises to a certain level, it will cause damage to the pump tube. Certain chemical conditions must be specified in the chemical compatibility table, especially temperature limits, to determine chemical compatibility.
If a chemical is not listed in the chemical compatibility table, or if the operating environment conditions of a plant differ too much from those specified in the table, a immersion test can be used to obtain more reliable information. This method can be used if there is no other information to refer to when determining chemical compatibility.
The immersion test procedure is as follows: Take a small pump tube and weigh it, measure the diameter and length. The pump tube was then placed in a closed container containing the relevant chemicals for 48 hours. The tube was taken out, washed and dried, weighed and measured, and the amount of change measured twice before and after was recorded. The pump tubing should also be inspected for signs of softening or embrittlement, which indicate that the chemical has caused damage to the pump tubing. A pumping test can be performed after one or several tubes are preselected. Each candidate pump tube sample should be put into trial operation under the actual environmental conditions of the factory, and the test results should be closely observed. If the pump tube does not show discoloration, swelling, cracking, loss of fluidity, or other signs of deterioration after the test run, it is proven to be compatible with the fluid.
In the era of relatively backward agricultural civilization, any spread of locusts, armyworms, borers and other pests will take big risk even low-yield crops, while the development of pesticides makes these pests under control, played an important role in the people's production and life and people health . The Birth of pesticide industry, greatly changed human history of completely dependent on the rice. Argo chemical have widespread in Pesticides, as well as insecticides fungicides, acaricides, herbicides, plant growth regulating agents. The use of pesticides greatly increased agricultural production to ensure that the population growth has brought a lot of material needs, but also take the problem of residues of pesticides. We are committed to the development of efficient, low toxicity and residue pesticide products, the annual export volume exceeds hundreds of tons.
