First, when selecting an electromagnetic diaphragm metering pump, consider the following key parameters: 1. The flow rate of the liquid to be measured. 2. The main characteristics of the liquid, such as chemical corrosion resistance, viscosity, and specific gravity. 3. System back pressure. 4. The suitable suction height. 5. Additional features required, such as analog control, pulse control, flow monitoring, or timer functions. Electromagnetic diaphragm metering pumps are widely used in various industrial applications due to their reliability and precision.
Second, what are the main advantages of electromagnetic diaphragm metering pumps? These pumps have only one moving part—the armature shaft—making them highly reliable. The fewer the moving parts, the lower the chance of mechanical failure. They are particularly well-suited for low-flow and low-pressure environments and perform well even under voltage fluctuations.
Compared to pumps with fixed frequency and variable stroke length, pumps with fixed stroke length and variable frequency offer more precise control. Since the dose per stroke is constant, the total dosage can be easily calculated by multiplying the dose per stroke by the frequency. This makes the relationship between frequency and dosage linear (e.g., 50% frequency equals 50% dosage). With external pulse or analog control, the dosage can be adjusted from minimum to maximum within seconds. Additionally, this design is more cost-effective than motor-driven stroke length adjustment.
Third, how do you interpret the performance curve of an electromagnetic diaphragm metering pump? 1. Locate the performance curve for the selected pump. 2. Identify the current system back pressure on the graph. 3. Determine the correction factor by aligning the back pressure value (in bar) on the curve and reading the corresponding factor on the left side. 4. Divide the required dosing amount by the correction factor to get the actual flow rate in ml/min or L/h. 5. Mark this calculated value on the dosing scale. 6. Use a ruler to find the appropriate stroke length and frequency settings that match the desired output. This ensures accurate and efficient operation of the pump.
