Description
Technical field
It the utility model is related to a kind of open type pump that can reversely export.
Background technology
At present, it is essentially all to be realized using reversal valve as reversing arrangement using the hydraulic system of open hydraulic pump
Reverse power is exported to hydraulic actuator.But such design not only increases the complexity and entirety of hydraulic system
Cost, while will also result in unnecessary restriction loss.
Utility model content
The purpose of this utility model is to provide a kind of open type pump that can reversely export, effectively to solve prior art not
Foot part.
To reach above-mentioned purpose, the utility model adopts the following technical scheme that：
The open type pump that can reversely export, including pump case, the pump case is interior to be provided with open type pump body and variable cylinder；Also include：
Control valve, it is connected by oil circuit with hydraulic oil source and variable cylinder；Displacement transducer, the corresponding variable cylinder are set；With reversely it is defeated
Go out component, be connected by oil circuit with the oil-out and inlet port of the open type pump body.
Preferably, the reversely output precision includes：Valve block, it is arranged on the pump case, is which is provided with by screw
The valve block oil inlet connected with the oil-out of the open type pump body and the valve block connected with the inlet port of the open type pump body
Oil-out；Two-way plug-in valve, it is inserted into the valve block；And cover plate, the corresponding two-way plug-in valve are fixed on the valve block.
Preferably, the control valve is arranged on the pump case by screw.Further, the control valve is changed for ratio
To valve.
Preferably, institute's displacement sensors are arranged on the pump case by screw.
The utility model enables open type pump reversely to export power source, reduces hydraulic system by using said structure
Reversal valve, on the premise of control function is met, hydraulic system is not only simplify, while also achieve energy-saving purpose.

Embodiment
As shown in Figures 1 to 4, the open type pump described in the utility model that can reversely export, pump case 1, open type are mainly included
Pump body 2, variable cylinder 3, control valve 4, displacement transducer 5 and reverse output precision 6 form.Wherein：
Described open type pump body 2 and variable cylinder 3 are assembled in the pump case 1.
Described control valve 4 is proportional reversing valve, be arranged on by screw on pump case 1 and by oil circuit and hydraulic oil source and
Variable cylinder 3 connects.
Described displacement transducer 5 is arranged on pump case 1 by the corresponding described variable cylinder 3 of screw.
Described reverse output precision 6 is mainly made up of valve block 61, two-way plug-in valve 62 and cover plate 63.Valve block 61 passes through spiral shell
Nail is arranged on pump case 1, which is provided with the valve block oil inlet 611 that is connected with the oil-out B of the open type pump body and with it is described
The valve block oil-out 612 of the inlet port S connections of open type pump body.Two-way plug-in valve 62 be inserted into valve block 1 and with valve block oil-feed
Mouth connects with valve block oil-out.The corresponding two-way plug-in valve 62 of cover plate 63 is fixed by screws on valve block 61.
Operation principle of the present utility model is as follows：
The forward and reverse for controlling open type pump body by control valve and displacement transducer exports.When forward direction exports, open
Formula pump body is from inlet port oil suction, the now two-way plug-in valve of reverse output precision effect in pressure oil fuel-displaced from oil-out
Under be closed.When reverse output, open type pump body is fuel-displaced from inlet port, is pressed oil from oil-out, now reversely output
The two-way plug-in valve of component is opened in the presence of pressure oil, increases force feed amount, and solving oil-out size deficiency causes oil
The problem of insufficient is measured, so as to realize the reverse output of open type pump body.
