Description
Technical field
The utility model relates to a kind of drilling mud pump, and especially a kind of lightweight high power four cylinder slurry pump, is mainly used in oil-drilling field.
Background technique
Petroleum drilling technology is developed the nineties, due to the exploitation of ocean deepwater oil gas field and the needs of a large amount of horizontal well drilling, not only make the power increase of rig, lifting capacity is strengthened, and makes drilling mud pump power also be increased to 1470 ~ 1618kW (2000 ~ 2200hp).Pump pressure then mentions 52.7MPa by 35MPa.The slurry pump of this new argument, at semi-submersible type, floating drill ship, the jack-up unit of transformation adopts in a large number.Along with the maturation of directed-drilling technique, more high-power, more high output pressure are proposed to slurry pump and the requirement of delivery pressure more stably.
Summary of the invention
The purpose of this utility model is to provide a kind of lightweight high power four cylinder slurry pump, this four cylinder pump design be on the basis of existing F pump, increase the requirement that a set of fluid cylinder, connecting rod etc. achieve four cylinders, the large portion of its easily damaged parts and F pump general.Its operation is identical with F pump, for replacing three cylinder F pumps, entering and dominate the market and lay a good foundation as early as possible.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of lightweight high power four cylinder slurry pump, comprise pump case, pinion shaft, Large Gear Shaft During, gear ring, connecting rod, mud guard, fluid end, described pump case, pinion shaft, Large Gear Shaft During, gear ring, connecting rod, mud guard, the pump case of fluid end and lightweight high power F1000 drilling mud pump, pinion shaft, Large Gear Shaft During, gear ring, connecting rod, mud guard, fluid end structure is measure-alike, the overall Brinell hardness of described Large Gear Shaft During is HB235-265, the Rockwell hardness of the flank of tooth is HRC50-55, described lightweight high power four cylinder slurry pump also comprises left bent axle and right bent axle, described left bent axle is connected with left positioning work piece, right bent axle is connected with besthomer, arrange between left positioning work piece and besthomer and carve block, described left bent axle, right bent axle is by carving block and positioning work piece compact siro spinning technology.
Further, described left bent axle and right bent axle arrange two crank throws and a gear ring respectively, and described gear ring is helical teeth.
The beneficial effects of the utility model are as follows: four cylinder slurry pump provided by the utility model adopt unique project organization, eliminate the impact of axial force on bearing.The power of four cylinder slurry pump of the present utility model is 1800 horsepowers (1343KW), delivery pressure is 7500PSI (52MPa); Change the herringbone tooth of bull gear into helical teeth, decrease manufacture difficulty; Adopt two bent axles, every root bent axle is arranged two and turn and a gear ring, two bent axles just constitute 4 and turn bent axle, and can meet more high-power, more high output pressure and the requirement of delivery pressure more stably, volume is little, lightweight, convenient transport and installing.
Accompanying drawing explanation
Fig. 1 is left bent axle and right bent axle connection diagram;
Fig. 2 arranges the schematic diagram that block is carved in location between left bent axle and right bent axle;
Fig. 3 is bent axle, high speed shaft, pump case connection diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described.
A kind of lightweight high power four cylinder slurry pump, as shown in Figure 1, comprise pump case, pinion shaft, Large Gear Shaft During, gear ring, connecting rod, mud guard, fluid end, described pump case, pinion shaft, Large Gear Shaft During, gear ring, connecting rod, mud guard, the pump case of fluid end and lightweight high power F1000 drilling mud pump, pinion shaft, Large Gear Shaft During, gear ring, connecting rod, mud guard, fluid end structure is measure-alike, the overall Brinell hardness of described Large Gear Shaft During is HB235-265, the Rockwell hardness of the flank of tooth is HRC50-55, described lightweight high power four cylinder slurry pump also comprises left bent axle 1 and right bent axle 2, described left bent axle is connected with left positioning work piece 3, right bent axle is connected with besthomer 4, arrange between left positioning work piece and besthomer and carve block 5, described left bent axle, right bent axle is by carving block and positioning work piece compact siro spinning technology, as shown in Figure 2.Described left bent axle and right bent axle arrange two crank throws and a gear ring respectively, and described gear ring is helical teeth.
The utility model adopts left, right two bent axles, every root bent axle is arranged two crank throws and a gear ring, two bent axles just constitute 4 and turn bent axle, as shown in Figure 2, left bent axle is subject to the axial force to the right that gear produces, right bent axle is subject to the axial force left that gear produces, its equal and opposite in direction direction is contrary, left bent axle is subject to the axial force to the right that gear produces, also be subject to the axial force left of right crankshaft gear generation by carving block combination simultaneously, its equal and opposite in direction direction is contrary, so, left bent axle be subject to axial force and be zero, equally, right bent axle be subject to axial force and be also zero, like this, bearing have impact on just not by axial force, Here it is carves the effect of block, not only located but also can eliminate the reason of axial force.How many regardless of the distance between left bent axle and right bent axle, carving block finally can contact, and in Fig. 2,6 for carving the final surface of contact of block and positioning work piece, and this contact applies axial forces can not to two bent axles, can not affect the axial clearance of bearing.
Four cylinder slurry pump provided by the utility model adopt unique project organization, eliminate the impact of axial force on bearing.The power of tradition three cylinder F pumps is 1600 horsepowers, and the power of four cylinder slurry pump of the present utility model is 1800 horsepowers (1343KW), delivery pressure is 7500PSI (52MPa); The utility model changes the herringbone tooth of bull gear into helical teeth, decreases manufacture difficulty; Adopt two bent axles, every root bent axle is arranged two crank throws and a gear ring, two bent axles just constitute 4 and turn bent axle, and can meet more high-power, more high output pressure and the requirement of delivery pressure more stably, traditional F 1600 triplex pump volume is 4883*1850*2839mm, the volume of the utility model four cylinder pump is 4270*2218*2655mm, these great about 26.5 tons of four cylinder pumps, great about 28 tons of F1600 triplex pump, therefore the utility model volume is little, lightweight, more convenient transport and installing.
It should be noted that; above-mentioned specific embodiment is only exemplary; under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improve or distortion all drops in protection domain of the present utility model.It will be understood by those skilled in the art that specific descriptions are above to explain the purpose of this utility model, not for limiting the utility model.
