Abstract
The utility model provides a reciprocating pump cross head with good greasy property, including the cross head body, the cross head body is cylindrical, and these cross head body lateral wall both ends all are provided with the oil bath that is used for storied oil liquid, be provided with in the oil bath and connect inside with the outside oilhole of cross head body, be connected with four helix oil grooves on the oil bath, four the helix oil groove is connected respectively in oil bath four corners position, type of being X -shaped, and structural down symmetry, four helix oil grooves of type X -shaped have increased oil groove length under the condition that does not change the oil groove width, and the oil mass that makes once reciprocal in -process provide increases, secondly the utility model discloses the oil groove that sets up all has the oil duct on the same radial section of cross head body, the arbitrary cross section of messenger's cross head body goes up the homoenergetic and obtains fine lubrication, has greatly reduced the stress concentration in the motion process simultaneously, reduces the danger of metal veneer, has increased economic benefits when having improved product quality.
Description
Technical field
The utility model belongs to reciprocating pump technical field, especially relates to a kind of reciprocating pump crosshead with favorable lubricating property.
Background technique
At present, the use of reciprocating pump is more and more extensive, wherein becomes the key that reciprocating pump uses the working life of fluid end assembly and power end assembly.And the crosshead in power end assembly becomes the key in key, crosshead is the part connecting piston and connecting rod in reciprocating pump, move reciprocatingly in casing skidway hole, there is leading role, but cross head design of the prior art is with ring oil groove, and between twice annulus, add straight line oil groove (as shown in Figure 2), in movement process crosshead twice circular oil groove in lubricant oil for once back and forth providing lubrication, whether visible lubrication is fully particularly important, once lubricate insufficient phenomenon such as dry friction, heating that will occur to aggravate the damage of crosshead.
Summary of the invention
Problem to be solved in the utility model is to provide that a kind of structure is simple, high lubricating effect, fall stress concentration, reduce that metal glues together, the reciprocating pump crosshead with favorable lubricating property of economic benefit of improving the quality of products, increase.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of reciprocating pump crosshead with favorable lubricating property, comprise crosshead block, described crosshead block is cylindrical, these crosshead block sidewall two ends are provided with the oil sump for storing fluid, be provided with in described oil sump and connect the inner and outside oilhole of crosshead block, described oil sump is connected with four helix oil grooves, article four, described helix oil groove is connected to oil sump corner location, in class X-shaped, structure is symmetrical up and down.
Described oil sump is oval.
Described oilhole is circular.
Described oilhole is positioned at oil sump one end.
Owing to adopting technique scheme, four helix oil grooves of class X-shaped, add oil groove length when not changing oil groove width, make once the oil mass provided in reciprocal process increase; Secondly the oil groove that the present invention is arranged all has oil duct on the same radial section of crosshead block, make the arbitrary section of crosshead block all can well be lubricated, the stress simultaneously significantly reduced in movement process is concentrated, reduce the danger of metal gummed, while improve quality of product, add economic benefit.
The beneficial effects of the utility model are: have that structure is simple, high lubricating effect, fall stress concentration, reduce that metal glues together, the advantage of economic benefit of improving the quality of products, increase.
Accompanying drawing explanation
Below by with reference to accompanying drawing describe the utility model particularly in conjunction with example, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explanation explanation of the present utility model, and do not form restriction of going up in all senses of the present utility model, in the accompanying drawings:
Fig. 1 is structural representation of the present utility model
Fig. 2 is the structural representation of crosshead in prior art
In figure:
1, crosshead block 2, oil sump 3, oilhole
4, oil groove
Embodiment
As shown in Figure 1, a kind of reciprocating pump crosshead with favorable lubricating property of the utility model, comprise crosshead block 1, described crosshead block 1 is cylindrical, and these crosshead block 1 sidewall two ends are provided with the oil sump 2 for storing fluid, is provided with and connects the inner and outside oilhole 3 of crosshead block 1 in described oil sump 2, described oil sump 2 is connected with four helix oil grooves 4, article four, described helix oil groove 4 is connected to oil sump 2 corner location, and in class X-shaped, structure is symmetrical up and down; Described oil sump 2 is oval; Described oilhole 3 is circular; Described oilhole 3 is positioned at oil sump 2 one end.
Four helix oil grooves 4 of class X-shaped, add oil groove 4 length when not changing oil groove 4 width, make once the oil mass provided in reciprocal process increase; Secondly the oil groove 4 that the present invention is arranged all has oil duct on the same radial section of crosshead block 1, make the arbitrary section of crosshead block 1 all can well be lubricated, the stress simultaneously significantly reduced in movement process is concentrated, reduce the danger of metal gummed, while improve quality of product, add economic benefit.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
