1st, the system in execution unit by installing an accumulation of energy oil circuit, and when cylinder is descending, fluid passes through bi-bit bi-pass electromagnetism
Reversal valve is added in accumulator, and when cylinder is up, the fluid of storage discharges in accumulator, and cylinder needs to export bigger pressure
When, one piece of pump and accumulator can be made to provide pressure to cylinder, when descending fluid some be stored into accumulator, be not
Whole oil return boxes, reduce the total amount of oil circulation, saved the energy.
2nd, the system installs an electromagnetic relief valve in supply unit pump group, ensures the pressure balance of whole system, prevents
Locking system hypertonia, when hypertonia, electromagnetic relief valve is opened, and carries out off-load, so the system has good security,
System selects the starting point of constant pressure pump, is namely based on low pressure and mass flow, realizes F.F.；High-pressure low-flow is realized in next step, was both protected
Pressure does not have excess traffic overflow and generated heat again, has saved the energy.
3rd, the present invention is simple in construction, design science is reasonable, is skillfully constructed, while no excessive redundant loop again, preferably
The function of pressure process is realized, ensure that the perfect of compression system function.
Brief description of the drawings
Fig. 1 is the system connection diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment.
A kind of tyre vulcanizer pressurized hydraulic servo-control system, as shown in figure 1, including execution unit and supply unit,
Execution unit is linked together with supply unit by oil circuit.
The execution unit includes oil cylinder 4, is connected between the rodless cavity fluid loop of oil cylinder and rod chamber fluid loop
Accumulation of energy oil circuit, the accumulation of energy oil circuit include be sequentially connected two-position two-way electromagnetic directional valve 3, pressure sensor 2, accumulator 1, two-way
Gate valve 12 and overflow valve 11.When cylinder is descending, fluid is added in accumulator by two-position two-way electromagnetic directional valve；When on cylinder
During row, the fluid of storage discharges in accumulator, when cylinder needs to export bigger pressure, can make the pump group 9 of supply unit
Give cylinder to provide pressure with one piece of accumulator, when descending fluid some be stored into accumulator, be not whole oil return boxes,
Reduce the total amount of oil circulation, save the energy.Under one one-way throttle valve 5 of the rodless cavity fluid loop of cylinder installation, cylinder
Cylinder downstream rate is adjusted during row, it is too fast to prevent that cylinder from declining, ensures the safety of cylinder.
The supply unit includes fuel tank 7, fitting machine pump group on the left side oil circuit of the fuel tank, pump group include one it is common
Motor and a constant pressure variable displacement pump, install one end of an overflow oil circuit on the oil circuit above the pump group, the overflow oil circuit it is another
One end connects fuel tank, installs an electromagnetic relief valve 10 on the overflow oil circuit, is opened when system pressure is excessive, carries out off-load.Institute
State and a joystick 8 is installed on the oil circuit below pump group, closed when fuel tank is cleared up, fuel tank is cleared up.The fuel tank
Interior installation flow gauge (FG), liquid level gauge, thermometer, cooler, electromagnetic water valve, are all the annex in fuel tank, ensure that fuel tank is normal
Oil suction, oil return.
The present invention operation principle be：
When cylinder is descending, fluid is added in accumulator by two-position two-way electromagnetic directional valve, when cylinder is up, in accumulator
The fluid of storage discharges, and when cylinder needs to export bigger pressure, one piece of pump and accumulator can be made to provide pressure to cylinder, under
During row fluid some be stored into accumulator, be not whole oil return boxes, reduce the total amount of oil circulation, saved energy
Source.Constant pressure variable displacement pump enter constant pressure operating mode (reaching its set pressure) after, it can according to system need provide maximum stream flow with
Under flow, system will it is more it is just more provide, system just few will be provided less, and it is constant-pressure pressure to keep system.As this germline of pressurize
When system does not need flow, as long as the flow of pump meets internal leakage, so as to reach the requirement for saving the energy.Where accumulator
There is a valve group in oil circuit, the overflow valve in valve group ensures the oil-filled hydraulic coupling of accumulator, the overflow when energy storage pressure is excessive.Pumping plant
One electromagnetic relief valve of place's installation, ensures the pressure balance of whole system, prevents that system pressure is too high, when hypertonia, electricity
Magnetic overflow valve is opened, and carries out off-load, so the system has good security, system selects the starting point of constant pressure pump, is exactly base
In low pressure and mass flow, F.F. is realized；In next step realize high-pressure low-flow, not only pressurize again there is no excess traffic overflow and generate heat, section
The about energy.
It is emphasized that embodiment of the present invention is illustrative, rather than it is limited, therefore present invention bag
