[Asia Fluid Network News] electromagnetic pump flow refers to the unit of time through the control surface of the fluid volume. Flow through the volume, quality of these two parameters, said the corresponding flow rate were referred to as volume flow, mass flow. Volume flow recorded as qv, mass flow recorded as qm. With the application of electromagnetic pump, the research on the influencing factors of electromagnetic pump flow has received more attention. If the control surface is not the overcurrent end face, the flow rate is usually expressed by the scalar product of the velocity vector v and the dA on the control surface. Through the flow of the micro-element flow tube dq, dq = v × dA = v × ndA, where n is the unit vector of the normal direction of the cell area. If the control surface is over-current, the velocity vector v is perpendicular to the dA = dA, q = ∫AvdA on the control surface. Through the understanding of electromagnetic pump, analyze the influencing factors of electromagnetic pump flow. For different electromagnetic pumps, electromagnetic pumps of different types, different working principle, the impact of traffic factors are also different. For the same electromagnetic pump may affect the flow of factors: 1, the type of electromagnetic pump voltage and voltage load size: for the same kind of electromagnetic pump, load AC or DC voltage, voltage, voltage stability or not, may Flow factors have an impact. 2, the performance of the electromagnet and loading direction: the design of the electromagnetic device, including the direction of the installation of electromagnets to produce electromagnetic effects of size. As well as the size of the electromagnet itself produces electromagnetic power, can affect the electromagnetic generation and size, thus affecting the flow. 3, the impact of geomagnetism on the electromagnetic device: Due to the device in the Earth under the influence of the earth's magnetic field, the magnetic field may affect the effective electromagnetic device within the device, affecting the flow of electromagnetic pump flow diversification of factors, but as long as the user According to the actual situation and reasonable use, these factors should be within the controllable range. Modern economy and science and technology are rapidly progressing, many of the equipment and products and the traditional production, the use of different ways, this is to better serve the production, I believe the research and upgrading of equipment and products will also continue.
