Description
Technical field
The invention belongs to the reciprocating pump of delivery pressure medium, is specifically a kind of vertical hydraulic borehole pump.
Background technique
The output hydraulic pressure pump of the various liquid mediums that the enterprises such as current oil, physical prospecting use, generally be mechanical power pump, namely with motor or diesel engine as power machine tool, becoming rotary motion by reducing gear, connecting rod etc. is horizontal reciprocating straight line motion, and complexity is paid in transmission, energy loss is large, total efficiency is low.Particularly high-power, huge discharge, high pressure pump, in order to connecting rod has enough large strength and stiffness, its accessory is very heavy and short, hydraulic cylinder generally can only within three (will be more complicated more than three cylinders), the motion momentum of movement parts is very large, not only start momentum large, energy loss is large, total efficiency is low, particularly ram and liquid medium suction mechanism are generally vertical setting mutually, and the sealing of the kinematic pair of horizontal setting and guiding element, under accessory Action of Gravity Field, sinking eccentric wear, cause cylinder body, sealing heel and toe wear is serious, lost efficacy very soon, the hydraulic cylinder sealing element of the drilling mud pump used as oil-well rig sometimes dozens of hour with regard to seal failure, hydraulic cylinder is also often changed.In order to improve this situation, designer of the present invention has done and has studied in earnest, proposes goal of the invention of the present invention.
Summary of the invention
Goal of the invention of the present invention puts forward to overcome current horizontal borer well pump above shortcomings.Design a kind of vertical, with power fluid force feed for power, drive oil hydraulic cylinder to drive the work of fluid power cylinder pressure, output liquid working medium.Namely a kind of vertical hydraulic borehole pump is provided.
Technical solution of the present invention realizes like this, this kind of vertical hydraulic borehole pump, have and suck menifold and discharge menifold and pump head, suck the bottom that menifold and discharge menifold and pump head are fixed on vertical frame, hydraulic cylinder is communicated with pump head, oil hydraulic cylinder (2) is fixed in frame (1), hydraulic cylinder (4) connection frame (1) and pump head (5), oil hydraulic cylinder (2) is coaxially connected by connecting rod (3) with hydraulic cylinder (4), and axes normal is installed in ground; The axes normal of the inhalation valve assembly (11) that pump head (5) is inner and expulsion valve core assembly (12) is installed in ground.Useful technique effect of the present utility model is: adopt vertical structure, oil hydraulic cylinder and hydraulic cylinder are fixed in the frame perpendicular to ground, make axes normal that oil hydraulic cylinder, hydraulic cylinder connect in ground, workpiece all works 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 large-size horizontal pump due to component weight sinking eccentric wears such as hydraulic cylinders, cause the problem that cylinder body, sealing heel and toe wear working life are short.By drilling pump from current reciprocating machine formula driving structure, innovation reform is the structure of the hydraulic reciprocating type driving that efficiency is higher, is suitable for the drilling pump of various different displacements and pressure, water injection pump, cement pump, is also suitable for the reciprocating pump under various ambient condition.
Accompanying drawing explanation
Accompanying drawing 1 is the front schematic view of vertical hydraulic borehole pump of the present invention, and accompanying drawing 2 is left surface generalized sections of accompanying drawing 1.Sequence number in accompanying drawing is illustrated as: 1, frame, and 2, oil hydraulic cylinder, 3, connecting rod, 4, hydraulic cylinder, 5, pump head, 6, suck menifold, 7, discharge menifold, 8, hydraulic cylinder sealing, 9, lubrication hydraulic fluid port, 10, seal ring group, 11, inhalation valve assembly, 12, expulsion valve core assembly, 13, one-way valve.
Embodiment
Below in conjunction with the embodiment provided in accompanying drawing, structure of the present invention and use are described in detail.With reference to accompanying drawing, this kind of vertical hydraulic borehole pump, there is 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), hydraulic cylinder (4) is communicated with pump head, oil hydraulic cylinder (2) is fixed in frame (1), hydraulic cylinder (4) connection frame (1) and pump head (5), oil hydraulic cylinder (2) is coaxially connected by connecting rod (3) with hydraulic cylinder (4), axes normal is installed in ground, the axes normal of the inhalation valve assembly (11) that pump head (5) is inner and expulsion valve core assembly (12) is installed in ground.
In order to the convenience of installing and keeping in repair, devise the structure of optimization, hydraulic cylinder (4) is connected with oil hydraulic cylinder (2) by connecting rod (3).Like this oil hydraulic cylinder power section and hydraulic cylinder do-part are isolated by connecting rod, facilitate installation, maintenance and debugging.
According to the high pressure characteristics of hydraulic cylinder, the hydraulic cylinder sealing case sealing of the upper design of hydraulic cylinder (4), sealed by hydraulic cylinder sealing case (8) and the seal ring group (10) in it, have lubrication hydraulic fluid port (9) in the upper design of hydraulic cylinder sealing case sealing (8), the inside of this lubrication hydraulic fluid port (9) is communicated with the through hole of seal ring group (10).The hydraulic oil that have adjusted pressure injects in sealing case through lubrication hydraulic fluid port, seal ring group and hydraulic cylinder guide sleeve is had to the pressure lubrication of pressure.The Lubricants force feed that have adjusted pressure is controlled by one-way valve (13), stop high-pressure working medium backflow, make to be full of lubricant film between the kinematic pair of hydraulic cylinder plunger and seal ring group and guide sleeve, thus improve lubricating efficiency, decrease the wearing and tearing of hydraulic cylinder sealing and guide element, improve its working life.
Vertical structural design of the present invention, makes oil hydraulic cylinder and hydraulic cylinder and pump head arrangement flexibly.Oil hydraulic cylinder (2) and hydraulic cylinder (4) and pump head (5) can as shown in Figure 1, and single arrangement is installed.
