Abstract
The utility model discloses such a excavators to adapt to full working scope energy saver, to solve to have existing for excavator when engine speed is higher than 1400 turns ∕ minutes, its output power and torque are relatively high, have more than needed, so energy consumption can be larger problem, the utility model takes multi-way valve and fuel tank on board a dredger（6）Between be also associated with check valve（5）And gear pump（3）, gear pump（3）Input terminal and fuel tank（6）Connection, gear pump（3）Output end passes through check valve（5）It is connect with the multi-way valve on excavator, gear pump（3）Output end also passes through solenoid valve（4）And cooler（2）With fuel tank（6）Connection.The advantages of to that can be made full use of power margin, further increase working efficiency.
Description
Technical field
The utility model is related to a kind of excavators, and full working scope energy saver is adapted to more particularly, to a kind of excavator.
Background technology
Currently, a kind of excavator disclosed in the market, hydraulic control system power is provided by engine, and hydraulic control
The parameter of pump in system is matched with the parameter of engine, therefore, is seen according to engine output curve, works as engine
When rotating speed is less than 1400 turns ∕ minutes, output power and torque are relatively low；When engine speed is higher than 1400 turns ∕ minutes,
Output power and torque are relatively high, have it is more than needed, so energy consumption can be larger.
Invention content
The purpose of this utility model be to provide it is a kind of power margin can be made full use of, further increase the digging of working efficiency
Pick machine adapts to full working scope energy saver.
In order to achieve the above objectives, a kind of excavator of the utility model adapts to full working scope energy saver, by check valve, gear
Pump, solenoid valve and cooler form, and check valve and gear pump, gear are also associated between multi-way valve and fuel tank on board a dredger
Pump input terminal is connect with fuel tank, and gear pump output terminal is connect by check valve with the multi-way valve on excavator, gear pump output terminal
Also it is connect with fuel tank by solenoid valve and cooler.
Check valve I is also parallel between the solenoid valve and fuel tank.
After this structure, due to being also associated with check valve and gear between multi-way valve and fuel tank on board a dredger
Pump, gear pump input terminal are connect with fuel tank, and gear pump output terminal is connect by check valve with the multi-way valve on excavator, gear pump
Output end is also connect by solenoid valve and cooler with fuel tank.When engine speed is less than 1400 turns ∕ minutes, solenoid valve must not
Electricity, the fluid in gear pump return to fuel tank by solenoid valve, cooler, do not consume output power；When engine speed is higher than
At 1400 turns ∕ minutes, solenoid valve obtains electric, and fluid in gear pump participates in interflow by the multi-way valve on check valve to excavator,
Power margin can be made full use of to realize, further increase the purpose of working efficiency.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Attached drawing 1 is the schematic diagram that a kind of excavator of the utility model adapts to full working scope energy saver.
In figure：1. 5. check valve of check valve I 2. cooler, 3. gear pump, 4. solenoid valve, 6. fuel tank.
Specific implementation mode
A kind of excavator of the utility model shown in attached drawing 1 adapts to full working scope energy saver, by check valve 5, gear pump 3, electricity
Magnet valve 4 and cooler 2 form, and check valve 5 and gear pump 3, gear are also associated between multi-way valve and fuel tank 6 on board a dredger
It pumps 3 input terminals to connect with fuel tank 6,3 output end of gear pump is connect by check valve 5 with the multi-way valve on excavator, and gear pump 3 is defeated
Outlet is also connect by solenoid valve 4 and cooler 2 with fuel tank 6；Check valve I is also parallel between the solenoid valve 4 and fuel tank 6
1。
