Description
Technical field
The utility model is related to rolling equipment hydraulic system and corresponding field of electrical control, refer specifically to a kind of hydraulic rotating
Motor braking energy-saving control system.
Background technology
All-hydraulic control rolling equipment, rotating mechanism are driven by fluid motor-driven by hydraulic pump and electro-hydraulic reversing valve
Dynamic control.By proportional reversing valve or electronic control Variable plunger pump regulating system flow, accurately to control rotating mechanism rotating speed.
Potentiometer analog signals are gathered by PLC, switch to digital quantity signal and then control proportional reversing valve or electronic control
The flow of Variable plunger pump realizes the rotating and variable speed of spinning movement；
Hydraulic motor service brake is realized using brake balancing valve.When hydraulic motor rotates, brake balancing valve is passed through in oil return
Overflow valve in group generates a large amount of thermal energy, and fluid temperature is caused to rise comparatively fast, a series of caused by easy generating system temperature is excessively high
Problem.
Utility model content
The utility model proposes a kind of hydraulic rotating motor braking energy-saving control device to solve more than technical problem.
The technical solution of the utility model is：A kind of hydraulic rotating motor energy-saving control device, the hydraulic rotating motor bag
Circuit and corresponding operation bench control system and original paper are performed containing spinning movement, including motor brake compensation valve group, in motor system
Increase bypass control valve in dynamic balancing valve group, the bypass control valve in-out end is connected to check valve outlet end, pump by pipeline
Source capsule road, bypass control valve are controlled by console PLC control logics, and in low-speed big mode activated motor, fluid exists
Outlet port passes through from bypass control valve.
Preferably：The bypass control valve is two solenoid directional control valves.
The beneficial effects of the utility model are：It may be implemented in when being not required to service brake, fluid flows away by bypass control valve,
Brake compensation valve group is avoided, unnecessary power consumption is rationally reduced, effectively controls Wen Sheng so that equipment is able to normal continuous operation.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the operation console panel schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, rolling equipment rotating mechanism hydraulic circuit, control unit is rotating mechanism hydraulic motor 1, and pumping source selects
Electronic control Variable plunger pump is selected, between Variable plunger pump and rotating mechanism hydraulic motor 1, rotating mechanism hydraulic system is set
Valve group 2 is balanced, during work, motor inlet and outlet of fuel channel is connected by unlocking the balancing overflow valve 3 in opposite circuit, so that horse
Up to normal work；During braking, oil inlet fuel cut-off, so as to cut off 3 unlocking condition of balancing overflow valve, oil inlet stops supplying at this time
Oil, oil outlet, which is closed, causes motor to be stopped, and reaches on-position.
In order to make in rotating mechanism hydraulic circuit, rotating mechanism hydraulic motor 1 passes through rotating mechanism hydraulic system balanced valve
During 2 work of group, the system Wen Sheng that Long-time Solutions lock loop is brought is reduced, the utility model is in rotating mechanism hydraulic system balanced valve
Increase bypass control valve 4, bypass control valve in group 2（4）In-out end is connected to 5 outlet end of check valve, pumping source pipeline 6 by pipeline
On, the function of this valve is two solenoid directional control valves, by controlling electromagnet（Obtain electric dead electricity）Fluid break-make is controlled, so that liquid
Road binders liquid is pushed back under without working condition selectively by balancing overflow valve 3 or bypass control valve 4.
Using operation console potentiometer handle 5,1 rotating of control rotating mechanism hydraulic motor starts and stops, passing through handle
Set interval（±10V）The openings of sizes of the valve of flow control valve, is set as movement in one direction in corresponding electronic control variable pump
Speed is 0%-100%, this section is continuously adjustable under stable state, so as to fulfill variable speed.With reference to current control principle
And applying working condition, by taking large full hydraulic four-roll plate bending machine as an example, upper roller is rotating mechanism fluid motor-driven, and when startup needs to apply
Low-speed big so that workpiece is steadily molded at a slow speed, this section technique need to repeatedly adjust correction, and operational motion, which includes, to be started, system
It is dynamic, rotating switching, after the completion of the stage to be corrected, into middling speed（At a high speed）Roll bending is molded, and according to above-mentioned technique, is selected for circuit
Selecting property overbalance overflow valve 3 or bypass control valve 4, control logic can be set：Potentiometer handle is in 0%-10%（Include rotating two
Kind situation）, bypass control valve C-YA10 and C-YA11 must not be electric, and fluid passes through balanced valve rotating mechanism hydraulic motor work
Make, potentiometer handle C-YA11 in 10%-100%, rotating forward obtains electric, and C-YA10 is obtained electric during reversion so that when high speed operates, oil
The obstructed overbalance overflow valve of liquid so as to the fluid heating that unlock balancing overflow valve is avoided to bring, reduces unnecessary power consumption, effectively
Control system circuit Wen Sheng improves system stability.
