Double-acting multi-cylinder slurry pump of the present utility model, its feature also is: selector valve adopts the proportional reversing valve of 3-position 4-way electricity liquid.
The beneficial effects of the utility model are, simple in structure, flow is big, and cost is low, is particularly useful for the supporting of all-hydraulic drill; Owing to adopt the double-acting hydraulic cylinder driving mode, the operational hydraulic cylinder that can be implemented in its driving in each stroke always has one discharging high-pressure slurry, and can realize the stable of pump housing discharge mud flow rate by the motion of controlling a plurality of double-acting hydraulic cylinder pistons.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. double-action fluid cylinder, 2. operational hydraulic cylinder, 3. piston is 4. discharged one-way valve, 5. sucks one-way valve, 6. proportional reversing valve, 7. public base, 8. hydraulic line assembly, 9. hydraulic station, 10. controller, 11. cable assemblies, 12. displacement transducers.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, the structure of the utility model device is, comprise parallel 1-8 the double-action fluid cylinder 1 that is provided with, present embodiment two groups of four fluid cylinders 1 that only drawn, the two ends of the bidirectional piston bar of each double-action fluid cylinder 1 are connected with piston 3 in operational hydraulic cylinder 2 cylinder sleeves respectively, each operational hydraulic cylinder 2 is respectively arranged with one and discharges one-way valve 4 and a suction one-way valve 5, the fluid import of each double-action fluid cylinder 1 is provided with a 3-position 4-way electro-hydraulic proportion reversing valve 6, each proportional reversing valve 6 is connected with hydraulic station 9 by hydraulic line assembly 8 respectively, the control electromagnet of each proportional reversing valve 6 is connected with controller 10 by cable assembly 11, by commutation and the spool aperture of controlling each proportional reversing valve 6, each double-action fluid cylinder 1 piston motion direction and speed be can adjust, and then the moving direction and the speed of the piston 3 in the relevant work fluid cylinder 2 controlled; Each double-action fluid cylinder 1 is provided with a displacement transducer 12, piston motion position signal in the self-corresponding double-action fluid cylinder 1 sends to controller 10 to each displacement transducer 12 with each through cable assembly 11, controller 10 is according to these position signals, the working state of each 3-position 4-way electro-hydraulic proportion reversing valve 6 of synthetic setting, thus reach the purpose of stablizing the slurry pump discharge flow rate.
Double-action fluid cylinder 1 quantity that slurry pump is joined is 1-8, and the quantity of operational hydraulic cylinder 2 and piston 3 thereof should be 2-16 mutually.
When the piston right lateral of double-action fluid cylinder 1, the piston 3 in the operational hydraulic cylinder 2 is also with same speed right lateral, and the discharge one-way valve 4 on the left side operational hydraulic cylinder 2 is closed, and sucks one-way valve 5 and opens, and this moment, this operational hydraulic cylinder 2 sucked mud; Discharge one-way valve 4 on the right side operational hydraulic cylinder 2 is opened simultaneously, sucks one-way valve 5 and closes, and this moment, this operational hydraulic cylinder 2 was discharged mud.When the piston left lateral of double-action fluid cylinder 1, left and right operational hydraulic cylinder 2 and opposite states when discharging one-way valve 4, the working state that sucks one-way valve 5 and right lateral thereof.Public base 7 can fixedly mount all double-action fluid cylinders 1, operational hydraulic cylinder 2, hydraulic station 9, hydraulic line assembly 8, controller 10, cable assembly 11.As required, hydraulic station 9 also can be unified to adopt the public hydraulic station of rig, needn't be equipped with separately by the pump housing.
The working principle of the utility model device is: drive a plurality of double-action fluid cylinders by hydraulic power, the end of each double-action liquid cylinder piston bar drives the piston in the operational hydraulic cylinder respectively, and the motion of this piston becomes high pressure to use for drilling well mud conditioning.Controller receives the movement position signal of each double-action liquid cylinder piston, and the output control signal is to control the motion control valve of each double-action fluid cylinder, and then reach the purpose that each operational hydraulic cylinder of control slurry pump is discharged mud flow rate, by the cooperation of a plurality of cylinder flows, guarantee the stable of mud flow rate in the high pressure pipe joint.
When controller 10 control 3-position 4-way electro-hydraulic proportion reversing valves 6 made the piston of double-action fluid cylinder 1 mobile to the right, operational hydraulic cylinder piston 3 right laterals in left side sucked one-way valve 5 and open, and discharge one-way valve 4 and close, and operational hydraulic cylinder sucks mud; Simultaneously, operational hydraulic cylinder piston 3 right laterals on right side suck one-way valve 5 and close, and discharge one-way valve 4 and open, and operational hydraulic cylinder is discharged mud; When the piston of double-action fluid cylinder 1 was mobile to the left, each operational hydraulic cylinder working state was opposite.By the flow of controller 10 each 3-position 4-way electro-hydraulic proportion reversing valve 6 each operational hydraulic cylinders of may command of control, and then the overall output flow of stable slurry pump.
Advantage and the effect of the utility model device are: 1) simple in structure, flow is big, and cost is low, is particularly useful for the supporting of all-hydraulic drill. 2) owing to adopt the double acting hydraulic cylinder type of drive, the operational hydraulic cylinder that can be implemented in its driving in each stroke always has one discharging high-pressure slurry, and can realize the stable of pump housing eliminating mud flow rate by the motion of controlling a plurality of double acting hydraulic cylinder pistons. 3) Hydraulic Station can adopt the public Hydraulic Station of rig, but also the pump housing is separately supporting, flexible configuration.
