What are the factors that affect the performance of the Electric Pump tube?
There are several factors influencing the following factors
1. Chemical compatibility
The pipe must be chemically compatible with the fluid to be pumped in order to have good Pump Pump performance and safety performance.
Many Electric Pump pump suppliers will provide chemical compatibility tables. However, engineers should be aware that chemical compatibility tables for Electric Pump tubing should be used, rather than chemical compatibility tables for general pipelines. Because the common piping is only in general contact with chemical substances and the Electric Pump tubing is in contact with chemical fluids under pressure conditions, the chemical compatibility level of ordinary piping is not equal to the chemical compatibility level of the Electric Pump tubing. Therefore, reference should be made only to the Electric Pump tubing, rather than the general chemical compatibility level of the piping with the associated substance, which would otherwise cause the Electric Pump to fail or break the leak, resulting in damage to the pump or a hazardous accident.
The pressure source of an Electric Pump fluid delivery system can vary. A backpressure is generated when the fluid is pushed through a filter, or the fluid is passed through a flow meter or valve, or when the fluid is pumped into a pressurized reaction vessel. Before selecting a pipe, the user should first make sure that all the pressure sources in the system have been clarified and that the measured values of the total system pressure have been obtained. When selecting pump tubing for Electric Pump, make sure that the pressure in the system does not exceed the recommended working pressure of the pump tubing. If the pressure is too high, the pump tube will bulge, with the pump head with poor, resulting in excessive wear and failure. System pressure greatly exceeds the capacity of the pump tube, and even make the pump tube burst, spray the fluid, endangering safety. After selecting a pipe, use it to ensure that the pressure is maintained within the manufacturer's recommended pressure range. If the Electric Pump system exceeds the maximum operating pressure, a simple pressure relief valve or pressure switch can be installed to prevent excessive pressure buildup. The effect of the pressure relief valve is: when the system pressure exceeds the set value, it will exhaust to the atmosphere, the system pressure down to a safe level. A complicated pressure switch can also be used. When the pressure value exceeds the set value, it will shut down the device or ring the alarm device via a relay. When the Electric Pump system pressure exceeds the safety line, the above two methods are conducive to safety.
The operating temperature range of the Electric Pump is another important factor to consider. Some pipes, such as silicone rubber, have a wide temperature range and are suitable for high temperature and low temperature processes. Some pipes such as Tygon and C-Flex are only suitable for a small temperature range. The end user should first understand the maximum temperature and minimum temperature in the system before selecting the tubing, and then ensure that the pump tube is safe to operate in this temperature range. In applications where temperature is required to be increased, the end user should consider the effect of temperature on the chemical resistance and pressure capacity of the pump tubing. When the temperature increases, the capacity of the Electric Pump tubing will be reduced.
With each roller in the Electric Pump pump head pressed against the pump tubing, Electric Pump pumps a certain amount of fluid, so the size of the pump tubing is directly related to the pumping flow, that is, the effect on the operation of the fluid delivery system Big. Pump tubing is a part of the design of high quality Electric Pump. The optimum size or optimum size range of the pump tubing is to be calculated. Where the size of the main refers to the pump tube diameter and thickness. The inner diameter determines the amount of fluid pumped by one revolution per turn, and the thickness determines the ability to restore the original shape after each roll, which greatly affects the service life of the pump tubing. The size of the pump tube relative to the pump head size is too small, the pump head can not catch the pump tube, Electric Pump pump tube will be pulled out of the pump head; and pump tube size is too small, the pump head roller can not suppress the pump , It will cause the Electric Pump pumping flow to be insufficient or complete failure. And if the tubing is too large, the excess pipe will fold between the roller and the pump shell or between the roll and the bite bed, resulting in excessive wear and premature failure. The end user should follow the manufacturer's recommendations when selecting the pump tubing to ensure that the system functions well. In some applications where high accuracy is required (eg chemical dosimeters), the size of the pump tubing is even more pronounced. A slight deviation in size will result in too much deviation in traffic or distribution. Although some manufacturers offer pump tubing sizes that are "close" to the recommended size, "look the same", but there are still gaps. So in order to make the pump system to achieve the best performance and accuracy, the user should be used with the manufacturer recommended size exactly the same size of the pump tube.
