Working principle
The import of the hydraulic control one-way valve is that from the mouth circulation can be injected in liquid, and exporting cannot can from the mouth for liquid
To inject circulation, when control mouth is the liquid that this mouthful has setting pressure, stream can also be can be injected in the liquid of outlet from the mouth
It is logical.
The oil quantity compensator (3), as shown in Figures 2 and 3.First ball (22) and the second ball (25) are by connecting rod
(24) it is connected to a fixed, when the oil pressure of upper port is greater than the oil pressure of lower port to setting value, the first ball (22) is in oil pressure
Under the elastic force effect of the first spring (21), the first hole (28) on shell (20) is sealed.The is pushed by connecting rod (24) simultaneously
Two steel balls (25) overcome the elastic force of second spring (26) and the counteragent of shell (20) lower port oil, allow the second ball (26) de-
From the closure to the second hole (29) on shell (20).In this way, for the system being recycled as oil, shell (20) lower end oral fluid
Body is flowed into oil storage tank (23) by second hole (29) of shell (20) and the right end hole of shell (20).Conversely, shell (20)
Upper port liquid is flowed into oil storage tank (23) by first hole (28) of shell (20) and the right end hole of shell (20).
The first flow compensator, when the pressure of the second hydraulic control one-way valve (32) outlet is greater than the first hydraulic control one-way valve
(31) when the pressure set points exported, the control port on the first hydraulic control one-way valve (31) drives the first hydraulic control one-way valve (31),
So that the first hydraulic control one-way valve (31) outlet conducting.In this way, the liquid to export to the first hydraulic control one-way valve (31) will flow into
One oil storage tank (33).Conversely, when the pressure of the first hydraulic control one-way valve (31) outlet is greater than the second hydraulic control one-way valve (32) outlet
When pressure set points, so that the second hydraulic control one-way valve (31) outlet conducting.In this way, coming to the second hydraulic control one-way valve (31) outlet
Liquid will flow into the first oil storage tank (33).
As shown in Figure 1, a kind of hydraulic system, there are two oil transportation mouth, an oil of the oil transportation mouth output with pressure is driven
When moving specified equipment work, while another hydraulic fluid port sucks back the oil previously exported, alternately working in reciprocating mode.
Electric energy is provided by control system (5), so that servo motor (4) rotates, servo motor (4) drives oil pump (6) work.
One oil transportation mouth of oil pump (6) exports the oil with pressure, another oil transportation mouth of oil pump (6) suck back previously exported with pressure
Oil.Due to being used equipment cannot be equal simultaneously in the flow of the oil of injection pressure and the oil excluded, and the oil of oil pump (6) discharge
It must be gone with the oil of sucking equal, the extra flow of oil of oil return circuit must thus be made to pass through oil quantity compensator from oil mass
(3) in leakage oil return tank (23), it is short of oil extraction out of oil tank (23) of flow.
In order to enable hydraulic system efficiently, stablize, reliably work, on the pipeline of oil transportation and using being additionally arranged in equipment
Sensor, sensor feed back to the operating status of system control system (5), and the application program analysis in control system (5) is anti-
After feedback signal, the energy of most suitable parameter is exported to taking motor (4).
As shown in Figure 1, executive module (9) is the hydraulic scheme of water knife working principle.Two of a kind of hydraulic system are defeated
Hydraulic fluid port, an oil transportation mouth pressure oil output push the side of oil cylinder piston, band to the interface of the side oil of two-way hydraulic cylinder (10)
Piston movement.The other side of two-way hydraulic cylinder (10) piston will the oil that is previously injected of discharge, return to a kind of hydraulic system
Another oil transportation mouth.Oil pump (6) constantly positive and negative rotation, two-way hydraulic cylinder (10) move back and forth.Water pump (13) is injected to two-way liquid
The intracavitary water in cylinder pressure (10) both ends gives accumulator (18) by two-way hydraulic cylinder (10) pressure injection.When the hydraulic pressure in accumulator (18) reaches
When setting value, used for nozzle assembly.
The water that two-way hydraulic cylinder (10) extrudes in order to prevent returns to water pump (13), when one end of two-way hydraulic cylinder (10) extrudes
When water, the 4th check valve (17) allows pressure water to pass through, and is defeated by accumulator (18), the first check valve (14) does not allow pressure water defeated
Feed pump (13).
When the other end of two-way hydraulic cylinder (10) extrudes water, third check valve (16) allows pressure water to pass through, and is defeated by
Accumulator (18), second one-way valve (15) do not allow pressure water to be defeated by water pump (13).
But when two-way hydraulic cylinder (10) Single port is in negative pressure or low pressure, the 4th check valve (17) does not allow accumulator (18)
High pressure water flow back to, and water pump (13) can be injected water by the first check valve (14) and give two-way hydraulic cylinder (10) Single port.
Conversely, when two-way hydraulic cylinder (10) another port is in negative pressure or low pressure, third check valve (16) does not allow accumulator (18)
High pressure water flows back to, and water pump (13) can be injected water by second one-way valve (15) and give two-way hydraulic cylinder (10) another port.
The control system is other than exporting optimal electric power and exporting to servo motor, moreover it is possible to provide instruction harmony message
Number and for adjustment operating member.
The position switch is also possible to approach switch.
