2. the control method of a hydraulic disc type brake device Hydraulic Station, is characterized in that containing following steps;
When normal operation, shutoff valve is opened, and 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 the by pass valve response pressure, 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 is circulated, improved the operating temperature of hydraulic oil, simultaneously, by pass valve keeps certain pressure, does not affect the normal operation of oil cylinder;
When needs are surveyed nitrogen pressure, pull Quick Measuring nitrogen shutoff valve, the truncated system pressure P enters in energy storage, system pressure P 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 to oil sump tank, after the nitrogen of compression discharges, by surveying the nitrogen device, pressure measuring tie-in, the pressure measurement pipeline, compression indicator shows the nitrogen pressure in energy storage, after recording nitrogen pressure, again Quick Measuring nitrogen shutoff valve is turned back to original position, system pressure P enters energy storage, for the energy storage fuel feeding, recovered original function, can not shut down survey nitrogen like this, and easy and simple to handle, save work-hours,
Pressure switch SB1 is connected to system pressure P by hydraulic power line, be responsible for the variation of monitored control system pressure P, as system pressure P during lower than setting value, pressure switch KM provides passive switch amount signal, signal is given alarm lamp HP power supply after oversampling circuit is controlled, and lights alarm lamp HP, notifies the user, system pressure P, lower than setting value, should process in time; The user learn or processed this event after, press reset button SB1, by the control of intermediate relay KA1, KA2, extinguish alarm lamp, alarm release, Hydraulic Station can work.
