The hydraulic system comprises a hydraulic oil tank and a hydraulic pump which are connected with a pressure header pipe and an oil return header pipe respectively, a hydraulic shunt is arranged between the pressure header pipe and the oil return header pipe, the hydraulic shunt is provided with an electronic driver and a hydraulic execution unit, and a central control unit is further provided and connected with the electronic driver through data lines. The bus-based hydraulic system can be widely applied to engineering machinery and provides accuracy of hydraulic control.
Description
Technical field
The utility model relates to a kind of engineering machinery technology, is a kind of hydraulic system of engineering machinery specifically.
Background technique
Hydraulic system is mainly by energy source device, and performance element is regulated control unit; Auxiliary element is formed, and the hydraulic system of particularly using on the excavator in engineering machinery at present is because systemic-function and performance requirement height; So system complex generally adopts the multi-way valve control of integrated form, oil pipe is more; Oil circuit is complicated, and additional auxiliary element is also more, the very inconvenience so system's Installation and Debugging and maintenance are got up.Though extensively adopted electromagnetic proportional valve at present, owing to do not have sensor, and import and export interlock control, can not reach the highest effect so realize the load-sensitive function, can not realize accurate control, the operator also can't learn the detailed status of system in real time.
Summary of the invention
The technical problem that the utility model will solve provides a kind of hydraulic system, and it is few that this hydraulic system has an oil pipe circuit, and control is convenient, the characteristics that precision is high.
In order to solve the problems of the technologies described above; The utility model comprises hydraulic oil container, and hydraulic oil container is connected with oil hydraulic pump, and oil hydraulic pump is connected with the pressure manifold; Hydraulic oil container is connected with the oil return house steward; Be connected with some hydraulic pressure branch roads between pressure manifold and the oil return house steward, the pressure of hydraulic pressure branch road is in charge of to be in charge of respectively with oil return and is connected with oil outlet with the oil inlet hole of electronic driver, and electronic driver bottom first hydraulic fluid port is connected with the 4th hydraulic fluid port with the 3rd hydraulic fluid port of hydraulic actuator with second hydraulic fluid port; This system also has central control unit, and central control unit is connected with electronic driver through datawire.
Said electronic driver is the double spool valve.
The utility model adopts the design of bus type hydraulic circuit, and multi-way valve has reduced the quantity of hydraulic oil pipe relatively, and hydraulic actuator has improved the precision of control greatly through electronic driver control simultaneously.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
