The main pump consists of two plunger-typeumps of serial variable displacement. The
wo pumps are controlled via full-powerariables, meaning that the sum of power ofwo pumps is kept constant. When a singleump is running, this pump can absorb theower of the other idle hydraulic pump tonsure the full use of engine power.
With hydraulic elements provided by world famous companiesand world advanced and mature hydraulic system of electronicpositive flow control, Sany excavators are capable of maintaininghigh operating efficiency on the basis of high system stability andbetter operability.
A quick circuit is added to the arm oil cylinder circuit. When thearm oil cylinder is extended, the oil return circuit is cut off andhydraulic oil flows from the return circuit into the cylinder via acheck valve. The hydraulic oil in arm cylinder rod end does notreturn the tank but goes directly to the cylinder head end. Thearm speed is increased as a result. The fuel consumption is lowunder this condition.
Pressure Loss Reduced with The Use of EfficientHydraulic Components
Improved pump efficiency: A variety of improvements, includingthe improvement of clearances between internal pump parts,minimizes the leakage.
The engine, main pump, main valve and other core components,tailored by the world famous suppliers for Sany, are designed inconsideration of the overall performance of Sany excavator. Thepositive flow hydraulic system and the advanced computerdynamic control technology are used to provide real-time matchbetween engine power and main pump power while effectivelymaximizing the machine performance and significantly reducingthe fuel consumption.
With closed-loop control, the controllerutomatically regulates the power absorbedy hydraulic pump according to the changesf engine load during the operation, keeping
he power of hydraulic pump matching up tohe power of engine at all times. Namely, theontroller sets the power of engine accordingo specific conditions to reduce the workingntensity of engine and ensures a stable andconomic engine application.
The electric control module has the capability of making quickresponse to the change of operating variables in order to
achieve optimum engine performance. It is fully integratedwith sensors of fuel, engine oil, air intake, coolant andexhaust system to conduct the real-time monitoring andauto-adjustment on the system conditions, which can ensurethe engine won't overload when the excavator works with fullload.
