Abstract
The utility model relates to an inverted L-shaped fluid end for a high-pressure reciprocating pump, which mainly comprises a suction valve, a fluid cylinder, a drainage pipe, an outlet valve and a suction pipe, wherein, the suction valve and the suction pipe are abutted against one side of a piston cylinder liner; the outlet valve is positioned on the outermost side of the fluid cylinder and close to the drainage pipe, and the outlet valve and the suction valve are mounted in the same pump head so that a fluid pathway in the fluid cylinder is inverted L-shaped. Therefore, the effect of the structure of the inverted L-shaped fluid end is obviously superior to the background art. The utility model has the advantages that the weight of the inverted L-shaped fluid end is over 30 percent lower than that of the L-shaped fluid end, the suction performance thereof is equivalent to that of an upright-type I-shaped fluid cylinder, and sealing components, coupling bolts and coupling nuts are reduced; therefore, the assembly is simple, and the operation is more reliable.
Description
Technical field
The utility model belongs to the petroleum gas operation and uses the reciprocating pump field.
Background technique
" L " type fluid end (see figure 1)s of the whole employings of high pressure drilling pump at present.There is following shortcoming in " L " type fluid end that uses on the high pressure drilling pump:
1. suction valve is away from piston-cylinder, and the suction runner is long, causes suction performance poor.
2. fluid cylinder is for dividing a body structure, and fluid cylinder overall weight, volume are bigger.
3. connect dismounting trouble, time and effort consuming between two fluid cylinders with bolt.
Summary of the invention
The utility model purpose provides a kind of reciprocating pump with anti-" L " type fluid end, is fit to various reciprocating pumps, especially on high pressure reciprocating pump, reaches suction efficiency height, simple and compact for structure, in light weight.
Technical solutions of the utility model: a kind of high pressure reciprocating pump mainly is made up of suction valve, fluid cylinder, discharge tube, expulsion valve, suction pipe with anti-" L " type fluid end; Suction valve, suction pipe are near piston-cylinder one side; Expulsion valve is positioned at fluid cylinder outermost and close with discharge tube, and expulsion valve and suction valve are installed in and make the fluid cylinder fluid passage be anti-" L " type in the same pump head.
Fluid cylinder is the monolithic overall structure, does not have coupling and a Sealing between the fluid cylinder, assembling easily, reliable operation.
The utility model advantage is to compare with background technique, and the weight saving of weight ratio " L " shape fluid end is more than 30%.Suction performance and vertical type " I " fluid cylinder is suitable.Sealing and attachment bolt, nut reduce, and assembling is easy, and it is more reliable to work.
Description of drawings:
Fig. 1 is the background technique structural representation.
Fig. 2 is the utility model structural representation.
Embodiment
A kind of anti-" L " type fluid end that is used on the reciprocating pump of the utility model, its structure diagram is seen Fig. 2, it is that it mainly is made up of suction valve 1, whole fluid cylinder 2, discharge tube 3, expulsion valve 4, suction pipe 5 etc.Suction valve 1, suction pipe 5 suck runner weak point and straight near piston-cylinder one side, and suction efficiency and vertical type fluid cylinder (" I ") structure is suitable; Expulsion valve 4 is positioned at the fluid cylinder outermost, and is close with discharge tube 3, discharges the runner weak point, and it is few to turn round, and hydraulic loss and impact reduce; Fluid cylinder 2 is the monolithic overall structure, does not have coupling and a Sealing between the fluid cylinder, assembling easily, reliable operation.Expulsion valve 4 is installed in the same pump head with suction valve 1.The fluid cylinder inner flow passage is anti-" L " type.
Claims (2)
1. a high pressure reciprocating pump mainly is made up of suction valve (1), fluid cylinder (2), discharge tube (3), expulsion valve (4), suction people's pipe (5) with anti-" L " type fluid end; It is characterized in that suction valve (1), suction pipe (5) are near piston-cylinder one side; Expulsion valve (4) is positioned at fluid cylinder (2) outermost and close with discharge tube (3), and expulsion valve (4) is installed in suction valve (1) and makes fluid cylinder (2) fluid passage be anti-" L " type in the same pump head.
