2. the control method of a kind of hydraulic disc type brake device Hydraulic Station according to claim 1, is characterized in that containing following steps;
When normally working, shutoff valve is opened, the oil feed line oil supply oil supply cylinder of Hydraulic Station, because the opened by pressure setting value of by pass valve is more smaller than the charge oil pressure setting value of Hydraulic Station, when charge oil pressure is greater than by pass valve response pressure, namely by pass valve is in opening, and the hydraulic oil of fuel feeding and oil return line starts to loop back fuel tank, after the hydraulic oil in pipeline obtains circulation, improve the operating temperature of hydraulic oil, meanwhile, by pass valve keeps certain pressure, does not affect the normal work of oil cylinder;
When nitrogen pressure surveyed by needs, pull Quick Measuring nitrogen shutoff valve, truncated system pressure enters in energy storage, system pressure directly accesses oil cylinder, do not affect the normal use of hydraulic disc brake system, simultaneously, shutoff valve passes through inner structure, hydraulic oil in energy storage is let out oil sump tank, after the nitrogen release of compression, by surveying nitrogen device, pressure measuring tie-in, pressure measurement pipeline, nitrogen pressure in compression indicator display energy storage, after record nitrogen pressure, again Quick Measuring nitrogen shutoff valve is turned back original position, system pressure enters energy storage, for energy storage fuel feeding, recover original function,
Pressure switch is connected to system pressure by hydraulic power line, be responsible for the change of monitored control system pressure, when system pressure is lower than setting value, pressure switch provides passive switch amount signal, signal is powered to alarm lamp after control circui, lights alarm lamp, notifies user, system pressure, lower than setting value, processes; User learns or after this event processed, presses reset button, and by the control of intermediate relay, extinguish alarm lamp, alarm release, Hydraulic Station can normally work.
