The working principle of electromagnetic pump inside the solenoid valve

Working principle of electromagnetic pump inside the solenoid valve solenoid valve r&d time electromagnetic pump is a kind of electromagnet drive high-pressure micro pump. It features compact structure, output pressure, no leakage, small volume, good dynamic adjustment, etc. Principle when energized coil electromagnetic pump, the slider movement to the right under electromagnetic force, sealed storage volume increases, the pressure is less than the inlet pressure, the liquid flows into the seal. When the electromagnetic pump power, the slider movement under the action of spring force to left, sealed storage volume decreases, and when the pressure is greater than the exit pressure, fluid flowing from the exit. Pulse frequency in Hz or Hz after the power rectifier, around the slider movement frequency and Hz or Hz, so fluid continuously flow from imports, exports. 。 Electromagnetic pump is mainly used for drink beverage machine, steam cleaner, blunt tooth cleaner, spray humidifier, pressurization filter, vacuum carpet cleaning. Electromagnetic pump selection consideration. A product output conditions. The types of fluid characteristics of fluid temperature, viscosity, corrosion, etc. B。 The pressure difference of electromagnetic pump can produce or overcome the maximum differential pressure on both ends of the pump body. C。 Self-priming height into liquid line is empty, fluid sources to the vertical height of the pump body. D。 Self-priming length into liquid line is empty, is to pump body fluid source pipe length. E. Self-priming time into liquid line is empty, from electricity to liquid suction to the pump body the time required for export. F。 Work cycle after a working power and the sum of power of time. G。 Cycle load = [ Electricity time/( Electric power + time) ] *。 Electromagnetic pump electrify heats up, so the cycle load and the polarization time longest determines the temperature rise of the electromagnetic pump. Electromagnetic pump temperature and environmental temperature determines the electromagnetic pump selection of insulation class ( Insulation class = ℃ = A = / = E/B/F = / H/N = / C =) 。 Current type and power input conditions of different input current waveform determine the mode of action of electromagnetic pump specific applications will have the ac/dc ( Constant voltage source and constant current source/battery/batteries / / dc generator/capacitance) / rectifier filter way, etc. Diode rectifier voltage and maximum effective current. Current ( Power) And output flow, pressure, approximate proportional relationship within a certain range, when the power to a certain extent, the solenoid valve to magnetic saturation, the strength is no longer increases, in addition, power and temperature rise is proportional to the. 。 Environmental factors and life environment and look forward to life is the electromagnet used different material or protection processing of important factor. Environmental factors including the temperature/humidity/field/electric/corrosive gas pollution. Liquid or dust/vibration shock and vibration, etc. 。 Installation and power connection installation general have screw/electromagnet casing threads. The slot embedded/other. Power connection means has lead/lead + terminal/other/plug pin.
