Detailed description of the invention
With specific embodiment, technical scheme is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, stretching-machine hydraulic power unit oil supply system of the present invention, it contains the fuel tank 8 of hydraulic oil, by electricity in including
The drone version pressure compensation variable pump 1 that machine drives, the inlet port S of drone version pressure compensation variable pump 1 is connected by pipeline and fuel tank
Connecing, the oil-in (in end) of oil-out P and high pressure filter connects, the oil-out (out end) of high pressure filter and plug-in list
Connecting to the oil-in A of valve A 3, oil-out B and the high-pressure stop valve 4 of plug-in one-way valve A connect, high-pressure stop valve and drawing
Stretch machine system oil sources P01 to connect；The remote control hydraulic fluid port PP of drone version pressure compensation variable pump 1 and pressure oil port P of proportional pressure control valve 5
Connecting, the oil-in A of the overflow hydraulic fluid port T and plug-in one-way valve B 7 of proportional pressure control valve connects, and plug-in one-way valve B's is fuel-displaced
Mouth B and fuel tank 8 connect；Pressure oil port P of electromagnetic relief valve 6 and the oil-out P of drone version pressure compensation variable pump connect, overflow
The oil-in A of hydraulic fluid port T and plug-in one-way valve B 7 connects.
In stretching-machine hydraulic power unit oil supply system of the present invention, pump station pressure grade is dependent on what proportional pressure control valve 5 set,
I.e. electric control system only need to change the set-point of comparative example overflow valve 5 and can change the pressure of drone version pressure compensation variable pump
The charge oil pressure of setting value, i.e. pumping plant.
The effect of above-mentioned electromagnetic relief valve 6 is: does not has load when one, guaranteeing electric motor starting and stop, is to pass through electromagnetism
Overflow valve 6 charged realizes；Two, as the protection of drone version pressure compensation variable pump 1, setting value is more than proportional pressure control valve
The set-point of 5 at least 15bar.
The operation principle of the present invention: when stretching-machine hydraulic power unit starts, the electromagnetic relief valve 6 charged setting time, such as 5
Second, drone version pressure compensation variable pump 1 directly passes through the overflow hydraulic fluid port of electromagnetic relief valve 6 by the hydraulic oil that oil-out P exports
T, electromagnetic relief valve 6 power-off after 8,5 seconds of the direct oil sump tank of plug-in one-way valve B 7, pressure oil port P of electromagnetic relief valve 6 is closed
Closing, hydraulic power unit pressure gradually rises until the force value of proportional pressure control valve 5 setting, and hydraulic power unit is in running, constantly
The set-point by comparative example overflow valve 5 change hydraulic power unit pressure.
When stretching-machine hydraulic power unit stops, the electromagnetic relief valve 6 charged setting time, such as 5 seconds, drone version pressure compensation became
The hydraulic oil that amount pump 1 is exported by oil-out P directly by the overflow direct oil sump tank of hydraulic fluid port T 8 of electromagnetic relief valve 6, motor with
Drone version pressure compensation variable pump 1 does not has load to stop, and extends motor and the service life of variable pump further.
The foregoing is only presently preferred embodiments of the present invention, rather than limitation of the present invention, in the essence without departing from the present invention
In the case of god and scope, all equalizations made according to scope of the present invention patent change and modify, and all should belong to the special of the present invention
Within profit protection domain.
