Abstract
The automatic diameter regulating piston for petroleum drilling slurry pump consists of piston rod, pressing nut, steel core, leather cup, pressing plate, disc spring, blocking nut and other parts. Therefore, the service life of the piston and the cylinder sleeve can be greatly prolonged, the drilling cost is reduced, and the labor intensity of workers is reduced.
Description
The utility model relates to a kind of various oil drilling single-acting slurry pump that can be used for, when work, can regulate the piston of diameter automatically.
Slurry pump is one of capital equipment of drilling well in Process of Oil Well Drilling, its main effect is to be pressed into to circulate in the well with the mud suction and by drilling rod to take landwaste out of, piston is the critical piece and the easily damaged parts of slurry pump, suction and pressure injection mud are all axially moved by piston and realize, because piston is to work under high pressure and mud medium condition, very easily wear and tear.The problem of pot type piston existence at present is that the gap that forms after the external diameter of piston rubber cup is worn can not in time compensate and be bad by the high-pressure liquid thorn; If the cylinder sleeve internal diameter that cooperates with piston on the other hand has mill greatly promptly can not use slightly and scraps.At present for main rubber material and steel by selecting high wear resistance for use in working life of improving both, and this approach has arrived the limit.Because can not further improve the working life of piston and cylinder sleeve, also just can not further reduce drilling cost, alleviates working strength of workers.
The purpose of this utility model is for the piston of a kind of diameter of regulating piston leather cup automatically that provides is provided, and it will make prolong greatly the working life of piston and cylinder sleeve, thereby can reduce drilling cost, alleviate working strength of workers.
The automatic path transfer piston of the utility model slurry pump is made of parts such as piston rod, promotion nut, piston steel core, piston cup, dish spring and pressing plates.Piston rod is mainly used in passing shaft to power and cooling water, is equipped with one on the piston rod and promotes nut, is mainly used in promotion piston steel core and moves forward compressing dish spring deposit elastic force; The piston steel core is mainly used in the high-pressure slurry pressure when bearing work; Leather cup is that rubber elastomer is mainly used in high pressure sealing, and it produces radial deformation under the compressing of dish spring, keeps good sealing state with cylinder sleeve and steel core all the time; The elastic force of dish spring is oppressed the leather cup distortion uniformly by pressing plate makes it remain good working order.
By above-mentioned structural design as can be seen, the automatic path transfer piston of the utility model slurry pump, promote nut and promote the piston steel core and oppress the dish spring forward owing to adopted on piston rod to install, make dish spring deposit elastic force, realize oppressing automatically leather cup reaches path transfer to radially being out of shape purpose, because its external diameter of distortion of leather cup keeps good sealing state with cylinder sleeve all the time, this has just prolonged the working life of piston and cylinder sleeve greatly.Because prolong and will significantly reduce drilling cost the working life of these two kinds of main easily damaged partss, alleviates working strength of workers.
Below further specify structure of the present utility model by an embodiment shown in the drawings, but scope of the present utility model is not limited to following embodiment.
Accompanying drawing is a main structure schematic representation of the present utility model:
The automatic path transfer piston of the mud pump for petroleum drilling of this example is made of parts such as piston rod 1, gland nut 2, set screw 3, steel core 10, leather cup 5, pressing plate 6, dish spring 7 and resistance shelves nuts 8, its technical characteristics is that piston rod 1 is for cylindrical, design is useful on the outer-hexagonal pulled, is used to connect the outside thread of gland nut and the thin axle of assembling steel core on piston rod, and the axle head screw thread is used for connecting and stops nut; Gland nut 2 is annular shape, and interior circle design has screw thread, and the cylindrical design has keyway and positioning screw hole, packs into from the thin axle of piston rod one end and uses scyewed joint between back and the piston rod; Steel core 10 is a circular cylindrical, and cylindrical is designed to the different cylinder of size diameter and is used to install leather cup, and interior circular hole and piston rod closely cooperate to guarantee sealing; Leather cup 5 is the elastomer of endless belt lip, and cylindrical contacts with cylinder sleeve (not shown) is moving, and interior circle and steel core closely cooperate; Pressing plate 6 is designed to annular dish shape, and outside diameter should be less than leather cup, interior circle and steel core Spielpassung; Dish spring 7 is designed to annular dish shape, and cylindrical should be less than the pressing plate diameter, and interior circle cooperates with stopping nut; Stop that nut 8 is designed to ring-type, inner hole thread connects with the piston rod screw thread, and the cylindrical step is used to install the dish spring; Set screw 3 and cotter pin 9 all are used to prevent thread looseness.As can be seen because the effect leather cup external diameter of dish spring force increases, the wear extent during its work can constantly be compensated, thereby can prolong the working life of piston greatly by above design.Use proof through the scene, it is above to double working life than pot type piston the working life of path transfer piston automatically, can significantly reduce drilling cost, alleviates working strength of workers.
