Abstract
The invention discloses a vertical hydraulic borehole pump which is provided with a suction manifold, a discharge manifold and a pump head which are fixed at the lower part of a vertical rack. A fluid power cylinder is communicated with the pump head; the fluid power cylinder is coaxially connected with the axis of a hydraulic cylinder fixed at the upper part of the rack; and the axis of the fluid power cylinder and the axes of suction and discharge valve core assemblies in the pump head are vertical to the ground. The vertical hydraulic borehole pump has the advantages that a vertical structure is adopted, the hydraulic cylinder and the fluid power cylinder are fixed on the rack vertical to the ground, so that the connecting axis of the hydraulic cylinder and the fluid power cylinder and the axes of the suction and discharge valve core assemblies in the pump head are vertical to the ground, and all working parts work in a vertical state. The vertical hydraulic borehole pump has simple and reasonable structure, and the sealing piece and the guide part of the dynamic hydraulic cylinder have long service lives. The existing reciprocating mechanical driving structure of the borehole pump is innovatively changed into the hydraulic reciprocating driving structure with higher efficiency. The invention is suitable for borehole pumps, water injection pumps and cement pumps with different displacements and pressures and is also suitable for reciprocating pumps under various medium conditions.
Description
Technical field
The invention belongs to the reciprocating pump of delivery pressure medium, definite saying is a kind of vertical hydraulic drilling pump.
Background technique
The output oil hydraulic pump of the various liquid mediums that enterprises such as present oil, physical prospecting use, generally be the mechanical power pump, promptly with motor or diesel engine as the power machine tool, moving by the transhipment of mutarotations such as reducing gear, connecting rod is horizontal linear reciprocating motion, and complexity is paid in transmission, energy loss is big, total efficiency is low.Particularly high-power, big discharge capacity, high pressure pump, for connecting rod has enough hard intensities and rigidity, its accessory weighs and lacks very much, the fluid power cylinder generally can only be within three (surpassing three cylinders will be complicated more), the motion momentum of movement parts is very big, it is big not only to start momentum, energy loss is big, total efficiency is low, particularly ram is generally vertical setting mutually with liquid medium suction mechanism, and the sealing of the kinematic pair of horizontal setting and guiding element, eccentric wear sinks under the accessory action of gravity, cause cylinder body, the sealing heel and toe wear is serious, very fast inefficacy, dozens of is hour with regard to seal failure sometimes for the hydraulic cylinder sealing element of the drilling mud pump that uses as oil-well rig, and hydraulic cylinder is also often changed.In order to improve this situation, designer of the present invention has done research in earnest, has proposed goal of the invention of the present invention.
Summary of the invention
Goal of the invention of the present invention puts forward in order to overcome present horizontal borer well pump above shortcomings.Designing a kind of vertically, is power with dynamicliquid pressure oil, drives oil hydraulic cylinder and drives fluid power cylinder working, output liquid working medium.A kind of vertical hydraulic drilling pump promptly is provided.
Technical solution of the present invention is to realize like this, this kind vertical hydraulic drilling pump, have the menifold of suction and discharge menifold and pump head, suction menifold and discharge menifold and pump head are fixed on the bottom of vertical frame, the fluid power cylinder is communicated with pump head, said fluid power cylinder be connected with the axis coaxle of the oil hydraulic cylinder that is fixed on upper rack and with the suction of said pump head inside and the axis normal of discharging spool in floor mounted.
Beneficial technical effects of the present invention is: adopt vertical structure, oil hydraulic cylinder and fluid power cylinder are fixed on the frame perpendicular to ground, the axis coaxle that makes oil hydraulic cylinder, fluid power cylinder connect connect and with the suction of said pump head inside and the axis normal of discharging spool in floor mounted, workpiece is all worked under plumbness, do not produce frictional force in the horizontal direction, therefore simple and reasonable, the particularly Sealing of power hydraulic cylinder and guiding element high life.Like this, overcome the large-size horizontal pump because component weight sinking eccentric wears such as fluid power cylinder cause cylinder body, sealing heel and toe wear, the problem that working life is short.From present reciprocating machine formula driving structure, innovation reform is the structure that the higher hydraulic reciprocating type of efficient drives with drilling pump, is suitable for drilling pump, water injection pump, the cement pump of various different displacements and pressure, also is suitable for the reciprocating pump under the various ambient conditions.
Description of drawings
Accompanying drawing 1 is the front schematic view of vertical hydraulic drilling pump of the present invention, and accompanying drawing 2 is left surface generalized sections of accompanying drawing 1.Sequence number in the accompanying drawing is illustrated as: 1, frame, 2, oil hydraulic cylinder, 3, connecting rod, 4, the fluid power cylinder, 5, pump head, 6, suck menifold, 7, discharge menifold, 8, fluid power cylinder sealing case, 9, lubricated hydraulic fluid port, 10, the seal ring group, 11, suction valve core assembly 12, expulsion valve core assembly, 13, one-way valve.
Embodiment
Below in conjunction with the embodiment who provides in the accompanying drawing, structure of the present invention and use are elaborated.With reference to accompanying drawing, this kind vertical hydraulic drilling pump, have suction menifold (6) and discharge menifold (7) and pump head (5), it is characterized in that said suction menifold (6) and discharge menifold (7) and pump head (5) are fixed on the bottom of vertical frame (1), fluid power cylinder (4) is communicated with pump head, said fluid power cylinder (4) be connected with the axis coaxle of the oil hydraulic cylinder (2) that is fixed on frame (1) top and with the inner suction of said pump head (5) and the axis normal of discharging spool in floor mounted.
During the convenience of installing and keeping in repair, designed the structure of optimizing, said fluid power cylinder (4) is connected with oil hydraulic cylinder (2) by connecting rod (3).Like this oil hydraulic cylinder power section and fluid power cylinder do-part are isolated by connecting rod, made things convenient for installation, maintenance and debugging.
High pressure characteristics according to the fluid power cylinder, in the upper design of said fluid power cylinder (4) sealing of fluid power cylinder sealing case, by fluid power cylinder sealing case (8) and the sealing of the seal ring group (10) in it, go up design at fluid power cylinder sealing case (8) and have lubricated hydraulic fluid port (9), the inside of this lubricated hydraulic fluid port (9) is communicated with the through hole of seal ring group (10).The hydraulic oil of having adjusted pressure injects in the sealing case through lubricated hydraulic fluid port, seal ring group and fluid power cylinder guide sleeve is had the pressure lubrication of pressure.Having adjusted the lubricated hydraulic oil of pressure is controlled by one-way valve (13), stop high-pressure working medium to reflux, make between the kinematic pair of fluid power cylinder plug and seal ring group and guide sleeve and be full of lubricant film, thereby improved lubricating efficiency, reduce the wearing and tearing of sealing of fluid power cylinder and guide element, improved its working life.
Vertical structural design of the present invention makes oil hydraulic cylinder and fluid power cylinder and pump head arrange flexibly.Oil hydraulic cylinder (2) and fluid power cylinder (4) and pump head (5) can be as shown in accompanying drawings 1, the single installation that is arranged in parallel.
