The operation principle of the present embodiment is:
The cavity end of first double-rod oil cylinder 14 and the lower end of the second double-rod oil cylinder 15 is provided with cushion dashpot 20, when double-rod oil cylinder When piston is run to both ends, piston is set to form a partially sealed chamber with cushion dashpot 20, caused high-pressure oil flow controls two-position four-way The pilot valve 12 that surges commutates, and then 3-position 4-way hydraulic directional valve 11 is commutated.
As shown in figure 1, the cylinder diameter and piston rod of the first double-rod oil cylinder 14 and the second double-rod oil cylinder 15 are equal, when two four When the logical pilot valve 12 that surges is in left position, 3-position 4-way hydraulic directional valve 11 is in right position, and now working connection P leads to A, oil return line B Logical T, the cavity high pressure fliud flushing of the lower end of the second double-rod oil cylinder 15, the cavity low pressure oil return of the lower end of the first double-rod oil cylinder 14, second pair The piston rod of rod oil cylinder 15 moves upwards, because the first double-rod oil cylinder 14 connects with the cavity of the upper end of the second double-rod oil cylinder 15, To the cavity of the upper end of the first double-rod oil cylinder 14, high oil pressure forces first pair for high-pressure oil flow in the cavity of the upper end of two double-rod oil cylinder 15 The piston rod of rod oil cylinder 14 moves downward, under the pressure of the lower end cavity inner high voltage oil of the second double-rod oil cylinder 15, two-position four-way liquid Dynamic pilot valve 12 is constantly in left position.Now the fluid media (medium) in mud pumping cylinder II and mud pumping cylinder IV is compressed, and with high pressure The form of fluid is discharged through discharging check valve along high pressure pipe joint 18, while mud pumping cylinder I and mud pumping cylinder III cavity volume are in negative Pressure, fluid media (medium) are inhaled into through sucking check valve along low-pressure manifold 19.
When the piston rod of the first double-rod oil cylinder 14 is close to lower end extreme position, the piston rod of the first double-rod oil cylinder 14 subtracts Speed, and make the oil pressure in cushion dashpot 20 increase, reach two-position four-way surge pilot valve 12 setting pressure (35MPa) when, make The two-position four-way pilot valve 12 that surges commutates right position, just promotes 3-position 4-way hydraulic directional valve 11 to commutate left position, and now working connection P leads to B, oil return line A leads to T, the cavity high pressure fliud flushing of the lower end of the first double-rod oil cylinder 14, and the cavity low pressure of the lower end of the second double-rod oil cylinder 15 is returned Oil, the piston rod of the first double-rod oil cylinder 14 moves upwards, and the piston rod of the second double-rod oil cylinder 15 moves downward, in the first double-rod Under the pressure of the lower end cavity inner high voltage oil of oil cylinder 14, the two-position four-way pilot valve 12 that surges is constantly in right position.Now mud pumping cylinder I Compressed with the fluid media (medium) in mud pumping cylinder III, and through discharging check valve along the row of high pressure pipe joint 18 in the form of high-pressure fluid Go out, while the cavity volume of mud pumping cylinder II and mud pumping cylinder IV is in negative pressure, fluid media (medium) is through sucking check valve along low-pressure manifold 19 It is inhaled into.
When the piston rod of the second double-rod oil cylinder 15 is close to lower end extreme position, the piston rod of the second double-rod oil cylinder 15 subtracts Speed, and make the oil pressure in cushion dashpot 20 increase, reach two-position four-way surge pilot valve 12 setting pressure when, make two-position four-way The pilot valve 12 that surges commutates left position, just promotes 3-position 4-way hydraulic directional valve 11 to commutate right position.
The piston rod of first double-rod oil cylinder 14 and the second double-rod oil cylinder 15 and so on circulates, and drives mud pump head 13 to do Work(, make the cavity volume of mud pump head 13 in the change of the alternating of high pressure and negative pressure, and via the suction fluid of low-pressure manifold 19, then via High pressure pipe joint 18 discharges fluid.Complete the pumping work of fluid media (medium).
The movement velocity of the piston rod of the present embodiment depends on the flow of plunger variable pump, reciprocating in hydraulic jack During, the hydraulic oil of confined space also plays the effect of brake piston bar simultaneously, thus it is unexpected to greatly reduce piston rod Commutate the hydraulic shock brought to system.The present embodiment passes through two four using the hydraulic oil of the cushion dashpot 20 at hydraulic jack both ends The logical pilot valve 12 that surges controls 3-position 4-way hydraulic directional valve 11, realizes automatic reverse function, and reversing mode, which has, steadily may be used Lean on, commutating period is short, without dead point, hydraulic shock is small the advantages of.The present embodiment is with linear motion generation of the piston rod of double-rod oil cylinder The linear motion for having replaced traditional toggle to change, the piston rod speed of service of double-rod oil cylinder is steady, and driving force is big.Together When by increasing the stroke of the piston of mud pump head 13 and double-rod cylinder piston rod, rushing for double-rod oil cylinder in the unit interval can be reduced It is secondary so that the suction check valve of mud pump head 13, discharge non-return valve operational state are more steady, greatly reduce emptying phenomenon.
The structure of the present embodiment hydraulic cylinder driven slush pump is simple, and it is more stable to export pressure, the flow of mud, holds Product efficiency high.Long stroke, low jig frequency, high pressure, huge discharge are easily achieved, can greatly improve the service behaviour of slush pump.And have Have small volume, in light weight, long lifespan, without impact, inertia it is small, commutation accurately and reliably, be pressure oil by using plunger variable pump Pump, it is easy to accomplish variable speed, automatically control and the advantages that overload protection.As needed rationally design pressure oil pump cylinder body with The ratio between effective active area of double-rod oil cylinder, supercharging purpose is can reach, realize the process requirements of high-pressure pump.Separate unit the present embodiment liquid It is reachable up to 63MPa, maximum stream flow that the power output of pressure driving double acting slush pump can reach 1200kw, maximum working pressure 3.86m3/min.The present embodiment be applied to oilfield high pressure, huge discharge, work long hours, to big sand than liquid remain to just Normal dispatch, it can also be competent at the task of drilling pump or fracturing pump.
Apply specific case in this specification to be set forth principle of the present utility model and embodiment, the above is real The explanation for applying example is only intended to help and understands method and its core concept of the present utility model;Meanwhile for the general of this area Technical staff, according to thought of the present utility model, there will be changes in specific embodiments and applications.To sum up institute State, this specification content should not be construed as to limitation of the present utility model.
