Beschreibung
Zusammenfassung:	The invention provides a method for obtaining a control range of a proportional valve, a testing system and a hydraulic system, and relates to the field of proportional valve performance testing, and the method for obtaining the control range of the proportional valve comprises the steps that the control voltage of the proportional valve is changed, and an actual relation curve of the actual valve element flow and the input voltage of the proportional valve is obtained; confirming a line segment, which is in linear positive correlation with the input voltage, of the actual valve core flow on the actual relation curve; and obtaining an end point voltage value of the line segment as a proportional valve control range. According to the method for obtaining the control range of the proportional valve, the proportional valve voltage control range is obtained, a proportional valve control instruction is determined again, the proportional valve is detected, a relation curve of the actual valve element flow and the i
