Pump Accessories Performance of Pump Tubes

Jun 11, 2018

What are the main factors affecting the actual performance of the pump tube of the pump fitting? Next we will analyze this issue and hope to provide some references for you. First of all, for the pump tube of the pump fitting, the tube needs to have chemical compatibility with the pumped fluid so that it can have good pumping performance and safety performance.


For users, with the continuous development of the market, the types of pipes for pump fittings are becoming more and more abundant, so users have more room when choosing. The second thing to consider is stress. In general, the pressure source of a fluid delivery system can vary. Back pressure is generated when fluid is pushed through a filter or pushed through a flow meter or valve, or pumped into a pressurized reaction vessel.


Therefore, when selecting the pump tube of the pump fitting, we should find out all the pressure sources in the system in advance and obtain the actual measured value of the total system pressure. Be aware that if the pressure is too high, it will cause the pump tube to bulge and fail to cooperate with the pump head, resulting in excessive wear and failure. If the system pressure greatly exceeds the capacity of the pump tubing, it can even cause the pump tubing to explode and spray fluids, endangering safety. Therefore, when the working pressure of the system is large, a simple pressure release valve or pressure switch can be installed to prevent accumulation of excess pressure.


Then we must pay attention to choose the appropriate size. As each roller in the pump head passes over the pump tube, the pump tube of the pump fitting will pump a certain amount of fluid, so the size of the pump tube is directly related to the pumping flow, that is, the operation of the fluid delivery system. Great. The inner diameter determines the amount of fluid pumped for each revolution of the rotor, and the thickness determines the ability of the pump tube to return to its original shape after each roller compaction. This ability greatly affects the service life of the pump tube.


In addition to considering its operating temperature. This is because the pump tubes for pump accessories of different materials have different working temperature tolerance ranges. In applications requiring a gradual increase in temperature, the user should consider the effect of temperature on the chemical resistance and pressure bearing capacity of the pump tube of the pump fitting.http://www.dmgcastings.com/
