Abstract
The invention discloses an oil drilling mud pump. The oil drilling mud pump is characterized in that the mud pump adopts a conversion mechanism composed of a power shaft and an inclined disc, wherein the power shaft is connected with the inclined disc through two symmetric flat keys, and the inclined disc is supported by utilizing the center of a central sphere as a fulcrum. The conversion mechanism can drive at least two cylinders, one end of each piston rod is connected with the inclined disc, and the other end is connected with one piston. An L-shaped sealing ring is arranged at the bottom of each piston. The oil drilling mud pump can reciprocate and is small in size, light and high in efficiency.
Description
Technical field
The present invention relates to a kind of mud pump for petroleum drilling.
Background technique
In petroleum industry, drilling well plays very important effect, and the key equipment of drilling well is slurry pump.At present, the machinery conversion mechanism of Conventional mud pump by crank block structure, rotary motion is become to-and-fro motion to realize piston acting, can not meet the requirement of modern drilling new process, it is large to there is impact force in conventional conversion mechanism, inertia is large, friction power loss is large, and tightness is low, and the technology that running speed is low lacks limit.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the mud pump for petroleum drilling providing a kind of practicality, and realize the to-and-fro motion of stock pump, volume is little, lightweight, and efficiency is high.
For reaching above-described object, a kind of mud pump for petroleum drilling of the present invention takes following technological scheme:
A kind of mud pump for petroleum drilling, is characterized in that, described slurry pump adopts the switching mechanism consisted of the swash plate that two symmetrical flat keys connections of installing are fulcrum support by center sphere centre line shaft.
Described slurry pump switching mechanism can drive at least two cylinder bodies, and one, piston rod connects swash plate, and other end connects piston.
Described piston base arranges L shape seal ring.
Adopt the present invention of as above technological scheme, there is following beneficial effect:
Adopt novel switching mechanism, realize improving power, reduce the object of volume, and tightness improves greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is seal ring partial enlarged drawing of the present invention.
Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, a kind of mud pump for petroleum drilling of the present invention, 1 is slurry pump line shaft, line shaft 1 both sides symmetry installs flat key 2, at center sphere 4 center be fulcrum support swash plate 3 on composition switching mechanism on drive two cylinder bodies 5,8 one, piston rod connects swash plate 3, and other end connects piston 6, arranges L shape seal ring bottom piston 6.This device slurry pump, structure is simple, and volume is little, and tightness is strong.
