Article Preview

Automatic unloading valve is the critical pressure control element of emulsion pump station, the unloading pressure and the recovery pressure after unloading of the pump are two important technical parameters of the emulsion pump station. The working performance of the unloading valve can be improved by research and simulation of the two parameters, making clear the state of the unloading valve for emulsion pump station when working, calculating the electromagnetic thrust when the pilot valve and main valve core act as well as the response speed of the unloading pressure, checking and correcting the original spring force. The variation range of pump station pressure can be controlled within ±0.5MPa through the effective control on the unloading pressure and recovery pressure of the automatic unloading valve for emulsion pump station, which ensures the stability, reliability and sensitivity of the pump station when working. The improvement of the automatic unloading valve technology of internal unloading type is adaptable to the development needs of high-yield and high-efficiency modern mine for high pressure and super larger flow pump station.
