Each working cyclesAfter cycle completes, stop the first oil well pump and the 3rd oil well pump, start the second oil well pump start intoRow cleaning, its main purpose is the attached membrane material of doing of removing in each Hydraulic Elements and pipeline,Detergent solution enters respectively two bye-passes through the 8th check valve and the 9th check valve, through each relevantElement, is then regulated through the 5th check valve cleaning fluid is entered wherein automatically clearly by three-way magnetic valveWash, or adopt manual cleaning, but may cause the waste of cleaning fluid.
(3) obtaining when the second two position, three-way electromagnetic change valve in sewage treatment mechanism of the present inventionThe right-hand member of electricity end, the first 3-position 4-way electro-hydraulic reversing valve, the 3rd 3-position 4-way electro-hydraulic reversing valveLeft end energising, when all the other electromagnet power-off, the first 3-position 4-way electro-hydraulic reversing valve and the three or threeFour-way electro-hydraulic reversing valve switches to respectively right position and left position, and the pressure oil of unidirectional volume adjustable hydraulic pump is logicalCross the first 3-position 4-way electro-hydraulic reversing valve and hydraulic control one-way valve and enter the rodless cavity that filters lift cylinder,Realize the once compression action of head, system pressure is now the setting of the first control overflow valve far awayValue, in the time that the second electro connecting pressure gauge reaches upper limit controlled pressure, makes the first 3-position 4-way electricity liquidThe left end power-off of the right-hand member of reversal valve and the 3rd 3-position 4-way electro-hydraulic reversing valve, system is by hydraulic controlCheck valve pressurize. When secondary compression, the right-hand member energising of the first 3-position 4-way electro-hydraulic reversing valve, isThe setting value that system pressure is pilot operated compound relief valve, when the first electro connecting pressure gauge reaches upper limit controlWhen pressure, the right-hand member power-off of the first 3-position 4-way electro-hydraulic reversing valve, system pressurize; Work as Pressure DropDuring to lower limit controlled pressure, the right-hand member of the first 3-position 4-way electro-hydraulic reversing valve is switched on again, unidirectional changeAmount hydraulic pump, to the rodless cavity repairing of filtering lift cylinder, gos up rodless cavity pressure, and system is opened againBeginning pressurize. When the left end energising of the first 3-position 4-way electro-hydraulic reversing valve makes the first 3-position 4-way electricity liquidWhen reversal valve switches to left position, the pressure oil of unidirectional volume adjustable hydraulic pump is through the first 3-position 4-way electricity liquidReversal valve enters the rod chamber that filters lift cylinder, simultaneously through one-way throttle valve reverse-conducting hydraulic control listTo valve, realize the release of pressure of hydraulic cylinder rodless cavity, release of pressure is after certain value, and piston rod retreats driveHead completes and unclamps action. After head unclamps, unidirectional volume adjustable hydraulic pump completes by chain driveDraw, get the action of plate. In the time of the second 3-position 4-way electro-hydraulic reversing valve left end energising, unidirectional variableThe pressure oil of hydraulic pump enters two-way quantitative hydraulic motor left end oil-in, two-way quantitative hydraulic pressure horseReach rotation, complete and get plate action by chain; When the right-hand member of the second 3-position 4-way electro-hydraulic reversing valveWhen energising, complete arm-tie action. The now right-hand member of the 3rd 3-position 4-way electro-hydraulic reversing valve energising,The pressure of system is the setting value of the second control overflow valve far away. The present invention is by electric contact type Pressure gaugeControl, realize the automatic repairing pressurize of system, the dwell time is long, and pressure stability is high. ThisBright also by the aperture of the one-way throttle valve of connecting on regulator solution control check valve oil circuit control, canTo avoid improper because of the translational speed of hydraulic control one-way valve internal control piston, cause that release of pressure is too fast to be drawnPlay impact shock and the noise of hydraulic system. Both met the release of pressure requirement of system, ensured againThe backhaul of hydraulic control one-way valve control piston is unaffected.

Operation principle: when the second two position, three-way electromagnetic change valve electric end, the one or three fourThe right-hand member of logical electro-hydraulic reversing valve, the energising of the left end of the 3rd 3-position 4-way electro-hydraulic reversing valve, all the other electricityWhen magnet power-off, the first 3-position 4-way electro-hydraulic reversing valve and the 3rd 3-position 4-way electro-hydraulic reversing valve divideDo not switch to right position and left position, the pressure oil of unidirectional volume adjustable hydraulic pump is by the first 3-position 4-way electricityLiquid reversal valve and hydraulic control one-way valve enter the rodless cavity that filters lift cylinder, realize the once pressure of headTight action, system pressure is now the setting value of the first control overflow valve far away, when the second electric contactWhen Pressure gauge reaches upper limit controlled pressure, make the right-hand member and of the first 3-position 4-way electro-hydraulic reversing valveThe left end power-off of three 3-position 4-way electro-hydraulic reversing valves, system is by hydraulic control one-way valve pressurize. SecondaryWhen compression, the right-hand member energising of the first 3-position 4-way electro-hydraulic reversing valve, system pressure is that pilot-operated type overflowsThe setting value of stream valve, in the time that the first electro connecting pressure gauge reaches upper limit controlled pressure, the one or threeThe right-hand member power-off of four-way electro-hydraulic reversing valve, system pressurize; When Pressure Drop is during to lower limit controlled pressure,The right-hand member of the first 3-position 4-way electro-hydraulic reversing valve is switched on again, and unidirectional volume adjustable hydraulic pump promotes to filteringThe rodless cavity repairing of cylinder, gos up rodless cavity pressure, and system starts again pressurize. When the one or threeThe left end energising of four-way electro-hydraulic reversing valve makes the first 3-position 4-way electro-hydraulic reversing valve switch to left positionTime, the pressure oil of unidirectional volume adjustable hydraulic pump enters to filter through the first 3-position 4-way electro-hydraulic reversing valve and carriesRise the rod chamber of cylinder, simultaneously through one-way throttle valve reverse-conducting hydraulic control one-way valve, realize hydraulic cylinderThe release of pressure of rodless cavity, release of pressure is after certain value, and piston rod retreats and drives head to complete and unclamp action.After head unclamps, the action that unidirectional volume adjustable hydraulic pump completes by chain drive and draws, gets plate. WhenWhen the second 3-position 4-way electro-hydraulic reversing valve left end energising, the pressure oil of unidirectional volume adjustable hydraulic pump entersTwo-way quantitative hydraulic motor left end oil-in, the rotation of two-way quantitative hydraulic motor, complete by chainBecome to get filter action; In the time that the right-hand member of the second 3-position 4-way electro-hydraulic reversing valve is switched on, complete and drawFilter action, by the filtration that back and forth realizes sewage of filter. Now the 3rd 3-position 4-wayThe right-hand member energising of electro-hydraulic reversing valve, the pressure of system is the setting value of the second control overflow valve far away.
