Abstract
The utility model relates to a cylindrical cam plunger pump which comprises a pump body, a cylindrical cam shaft and a driving device. The cylindrical cam shaft is arranged in the pump body, the driving device is used for driving the cylindrical cam shaft to rotate, cam grooves arranged in a curve mode are annularly arranged along the circumference of the cylindrical cam shaft, a plurality of pairs of symmetrically arranged piston cylinders and a plurality of T-shaped piston rods are arranged outside the pump body in the axial direction, every pair of symmetric piston cylinders is connected through two ends of horizontal rods of the T-shaped piston rods, and the ends of vertical rods of the T-shaped piston rods are movably connected to the cam grooves through fixed bearing wheels. The cylindrical cam plunger pump can achieve the multi-cylinder multi-stroke effect on the conditions of low costs so as to achieve the requirements of large displacement output and high pump efficiency.
Description
Technical field
The utility model relates to a kind of pump repeatedly that liquid is carried that is applied to, and is specifically related to a kind of cylindrical cam plunger pump.
Background technique
Pump is widely used in the middle of the productions such as brick well, acid fracturing, water filling at oilfield repeatedly.Along with petroleum industry is more and more higher to the requirement of pump repeatedly, pump is high towards delivery pressure repeatedly, flow large, manufacture and easy to maintenance, the future development such as Pulse of flow and pressure is little, volume is little and quality is light.
At present, the pump repeatedly of middle extensive use is mostly common plunger pump at the scene, its structural type mostly is when acting on pump repeatedly, relative displacement is less, pump efficiency is low, unit is difficult to meet the high request of present brick well, acid fracturing, water filling etc., needs multimachine also with improving discharge capacity, but so just cause place floor space large in order to reach requirement, total energy consumption is high, finally causes cost greatly to improve.
Model utility content
In order to overcome the deficiencies in the prior art part, the utility model provides a kind of cylindrical cam plunger pump with the many strokes of multi-cylinder, has solved existing plunger pump and mostly has been single cylinder single-stroke pump repeatedly, the deficiency that relative displacement is little, pump efficiency is low.
Adopt following technological scheme in order to solve the existing problem the utility model of background technique: a kind of cylindrical cam plunger pump, comprise the pump housing, cylindrical cam axle, drive unit, described cylindrical cam axle is arranged in the pump housing, described drive unit is used for driving cylindrical cam axle to rotate, described cylindrical cam axle is equipped with the cam path of arrangement of curves along the whole body, the described pump housing is provided with some to the piston cylinder being arranged symmetrically with and some T-shaped piston rods outward vertically, and in every pair of symmetrical piston cylinder cylinder, all the horizon bar two ends by T-shaped piston rod connect, vertical bar one end of described T-shaped piston rod is movably connected in described cam path by being fixed with bearing wheel.
By this setting, when cylindrical cam axle in drive unit drives the pump housing rotates, this cylindrical cam axle just can drive the some T-shaped piston rod motion repeatedly simultaneously outside the pump housing, and each T-shaped piston rod can compress again two piston cylinders simultaneously, thereby this cylindrical cam plunger pump just can reach the effect of the many strokes of multi-cylinder in situation cheaply, to reach large discharge capacity output, requirement that pump efficiency is high.
Further setting of the present utility model: offer vertically the T-shaped piston rod of some confessions on the described pump housing and be connected in the guiding groove in cam path, and the radial length of described guiding groove is greater than the radial length of cam path.
By this setting, be conducive to the motion repeatedly of T-shaped piston rod more light accurately, can avoid T-shaped piston rod repeatedly producing friction with the two ends of guiding groove in movement process simultaneously.
Further setting of the present utility model: all there are discharge opeing safety check and inlet check valve in described piston cylinder outer end by pipeline connection.
By this setting, be conducive to better realize when T-shaped piston rod repeatedly moves in piston cylinder the process of discharge opeing and imbibition.
Further setting of the present utility model: described drive unit is straight stroke electric formula drive unit.
By this setting, this drive unit can better be controlled the rotation of cylindrical cam axle, is conducive to further improve pump efficiency.
The beneficial effects of the utility model are: the utility model drives the motion repeatedly simultaneously of the multiple T-shaped piston rods of pump by a cylindrical cam axle, and each T-shaped piston rod can compress again two piston cylinders simultaneously, thereby in situation cheaply, just can reach the effect of the many strokes of multi-cylinder, to reach large discharge capacity output, requirement that pump efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment's cylindrical cam plunger pump.
