Beschreibung
Zusammenfassung:	A quick-change hydraulic system capable of automatically controlling pressure and flow comprises a main valve assembly, a main pump assembly, a quick-change assembly and a controller, the main pump assembly comprises a main pump A and a main pump B, the main valve assembly comprises a main valve A and a main valve B, the main pump A is connected with the main valve A through a hydraulic pipeline, and the main pump B is connected with the main valve B through a hydraulic pipeline; an input end of the controller is connected with a quick-change operation switch which is connected with a quick-change reversing valve coil; an output end of the controller is connected with the main pump B and the main valve B; and a control signal of the quick-change control switch is introduced into the controller, so that during quick-change operation, the controller sends a control instruction to a main pump control proportional valve and a main valve loading valve at the same time to output flow, the hydraulic requirement of t
