[embodiment]
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Embodiment: mineral fluid high-pressure delivery pump, as depicted in figs. 1 and 2, it comprises the pump housing 20, be located at the piston 15 in the pump housing 10, the conveying cylinder 7 that cooperates with piston 15, the piston actuated axle 16 that is connected with piston 15, the driving mechanism of driven plunger live axle 16 actions, it is characterized in that being provided with in the described pump housing 20 drive cylinder 9 that matches with driving mechanism, be provided with the piston actuated shaft driver 17 that is connected with piston actuated axle 16 in the drive cylinder 9, be provided with scrubbing-cooling chamber 8 between described conveying cylinder 7 and the drive cylinder 9, piston actuated axle 16 1 ends and piston 15 removably connect, and the other end passes scrubbing-cooling chamber 8 and enters drive cylinder 9 and be connected with piston actuated shaft driver 17.Driving mechanism is a hydraulic drive mechanism.Corresponding scrubbing-cooling chamber 8 places are provided with opening on the pump housing 20, and opening is provided with lid 18.Two oil hydraulic cylinders about piston actuated shaft driver 17 is separated into hydraulic drive cylinder 9, hydraulic drive mechanism with about two oil hydraulic cylinders be connected, be used for 17 side-to-side movements of driven plunger drive shaft part.
Hydraulic drive mechanism comprises the hydraulic oil pumping mechanism that is connected with drive cylinder 9 by control mechanism 10 (control valve group), be located at the signal generation part that matches with piston actuated shaft driver 17 at drive cylinder 9 two ends, described signal generation part is electrically connected with signal receiving element on the control mechanism 10.
Hydraulic oil pumping mechanism comprises power mechanism 13 (motor), and by hydraulic oil container 11 and duplex metering pump 12 that control mechanism 10 is connected with hydraulic drive cylinder 9, duplex metering pump 12 is connected with power mechanism 13.
Carry cylinder 7 to be connected with the mineral fluid high-pressure conveying equipment, the mineral fluid high-pressure conveying equipment comprises the last one-way valve 4 and the following one-way valve 1 of upper and lower settings, the middle conveying of being located between two one-way valves held body, the pressure balance accumulator 5 that is connected with last one-way valve 4 is carried cylinder 7 to hold parts with middle conveying and is connected.
The middle conveying held body and comprised that the conveying that has three delivery ports at least holds body 3, connects and carries a delivery port that holds body 3 and connect the transporting elbow 2 of one-way valve 1 delivery port down; Two other delivery port that described conveying is held on the body 3 is connected with the delivery outlet of carrying cylinder 7 with last one-way valve 4 respectively.
In use, duplex metering pump 12 is discharged the hydraulic oil in the hydraulic oil container 11 under the drive of power mechanism 13 (motor), the hydraulic oil of discharging (is the main valve group through control mechanism 10, as four-way valve) enter left hydraulic cylinder/right oil hydraulic cylinder, driven plunger drive shaft part 17 left/right motion, piston 15 is advanced or retreats to finish to be pumped into subsequent processing/open the play action that one-way valve 1 sucks mineral fluid in conveying cylinder 7 by last one-way valve 4 with entering the mineral fluid carried in the cylinder 7.This type of all-hydraulic pumping system connecting rod features simple structure compared to prior art, quality is little, low cost of manufacture; The control valve prescription realizes that just the control pump machine starts and stop action, avoids that the connecting rod quality is big, inertia is big, starts the shortcoming that stops difficulty.
During hydraulic drive mechanism work, duplex metering pump 12 is discharged the hydraulic oil in the hydraulic oil container 11, when hydraulic oil enters left hydraulic cylinder by sealed circuit, drive piston 15 withdrawals and produce negative pressure, at this moment mineral fluid passes through one-way valve down, be inhaled into and carry cylinder 7, carried out the end of right oil hydraulic cylinder up to piston actuated shaft driver 17, contact picked up signal with signal generation part (near switch), signal generation part sends to the signal receiving element with signal, makes the work of control valve group realize the automatic reverse of the mobile direction of hydraulic oil.Hydraulic oil after the commutation enters left hydraulic cylinder, pushes piston 15 and will carry the mineral fluid in the cylinder to be transported to next operation by last one-way valve 4 to left movement, finishes a suction, send the mineral fluid process.Because left and right oil hydraulic cylinder is constantly alternately to finish separately suction, send action, finishes the operation of pumping mineral fluid.Because hydraulic oil and fed sheet of a media (mineral fluid) separate fully, when changing piston 15 it is withdrawn into scrubbing-cooling chamber 8, in scrubbing-cooling chamber 8, change piston 15, isolate fully, realize that the phenomenon of polluting does not mutually appear in fed sheet of a media (mineral fluid) and hydraulic oil with oil hydraulic cylinder 9.During work, fills with water in the scrubbing-cooling chamber 7, the effect of play cooling, lubricating.
