Factors that cause fluctuations in the flow of coal-water slurryApplicability SolutionOther solutionsWhen the solid particles of the coal slurry are rubbed through the surface of the electrode, the contact electrochemical potential of the electrode surface suddenly changes, resulting in the "spike pulse interference" of the electrode detected by the sensor output.√The sensors with special materials and structure and special transducers.
/The pulsation caused by the pulsating flow of the 'screw pump' at different speedsxThe true fluctuation of flow, the flow meter can't solve.
.Lengthening the front straight section of the flowmeter is the best way to solve the pulsation caused by the work of the coal slurry pressurization pumpPulsating flow (6%~15%) caused by a 'piston pump' or 'diaphragm pump'xThe magnetized metal particles are adsorbed on or near the measuring electrode, forming a polarization voltage on the electrode, reducing the measurement accuracy of the electromagnetic flowmeter and further increasing the amount of fluctuation√After discharge pressure, take out the electrode (removable electrode), clean it and install it again.Reducing the metal particles in the coal slurry
