Abstract
The invention discloses a vertical multi-cylinder double-action reciprocating pump fluid end. All pump valves are arranged on one side of inner space of the reciprocating pump fluid end and are arranged on one side of a piston, maintenance space is reserved in the side with the pump valves, maintenance within short distances is facilitated, operation is convenient, and therefore maintenance time is shortened, maintenance working strength is reduced, and time and labor are saved.
Description
Technical field
The present invention relates to pump valve, especially a kind of vertical Multi-cylinder dual reciprocating pump hydraulic-end.
Background technique
Current vertical Multi-cylinder dual reciprocating pump hydraulic-end for same piston assembly two groups of pump valves (suction valve 1, expulsion valve 2) be arranged in piston 3 both sides, piston rod 4 passes reciprocating pump hydraulic-end; As depicted in figs. 1 and 2.Restriction due to installing space, can only leave pump valve service clearance in a side of pump, like this, not keep in repair when staying service clearance one side pump valve and just have a lot of difficulties, pump valve is away from the position at people station, and there is an interval of the parts such as piston rod, eyes are difficult for seeing, cause operation very inconvenient, bad exerting oneself, service cycle is long, and labor intensity is large.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of and leave detection space in a side, the vertical Multi-cylinder dual reciprocating pump hydraulic-end of pump valve easy-maintaining.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of vertical Multi-cylinder dual reciprocating pump hydraulic-end, comprise pump valve body, described pump valve body interior is provided with intake chamber and discharges chamber, it is characterized in that, described intake chamber and discharge chamber are positioned at the same side of described pump valve body interior, an other side of described pump valve body interior is provided with piston cylinder, in this piston cylinder, piston is installed, this piston is connected with the piston rod that passes described pump valve body, between described intake chamber and discharge chamber, be provided with bottom flow channels and top flow channels, described bottom flow channels is lower than top flow channels, upper with described piston cylinder respectively of this bottom flow channels and top flow channels, lower chambers is communicated with,
Between described intake chamber and described bottom flow channels, be provided with suction valve, between described discharge chamber and described bottom flow channels, be provided with expulsion valve;
Between described intake chamber and described top flow channels, be also provided with suction valve, between described discharge chamber and described top flow channels, be also provided with expulsion valve.
The number of described top flow channels and bottom flow channels is all two, and the number of described piston cylinder is two or more, and top flow channels and bottom flow channels are communicated with the upper and lower chamber of a corresponding piston cylinder respectively.
Good effect of the present invention is:
Vertical Multi-cylinder dual reciprocating pump hydraulic-end of the present invention, only the side in this reciprocating pump hydraulic-end inner space arranges pump valve (being suction valve and expulsion valve), pump valve is all placed in a side of piston, one side of pump valve is stayed space for maintenance in realization, facilitate in-plant repair and maintenance, easy to operate, thus shorten engineering time and reduce the labor intensity keeping in repair, time and labour saving.

Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail to (this patent take double cylinder double acting introduce as example).
As shown in Figures 3 to 5, a kind of vertical Multi-cylinder dual reciprocating pump hydraulic-end, comprises pump valve body, and this pump valve body interior is provided with two intake chambers and two discharge chambers, and this intake chamber and discharge chamber are positioned at the same side of pump valve body interior.An other side in pump valve body interior is provided with two piston cylinders, in these two piston cylinders, piston 3 is all installed, and this piston 3 is connected with the piston rod 4 that passes pump valve body.
As shown in Figure 4, an intake chamber and a discharge chamber in pump valve body interior left side, in the intake chamber in left side with discharge between chamber and be provided with bottom flow channels and top flow channels, bottom flow channels is lower than top flow channels, and this bottom flow channels and top flow channels are all communicated with a piston cylinder at its rear portion; Between intake chamber and bottom flow channels, be provided with the first suction valve 11, discharge between chamber and bottom flow channels and be provided with the first expulsion valve 21; Between intake chamber and top flow channels, be also provided with the second suction valve 12, discharge between chamber and top flow channels and be also provided with the second expulsion valve 22.
An intake chamber and a discharge chamber on pump valve body interior right side, in the intake chamber on right side with discharge between chamber and be provided with bottom flow channels and top flow channels, bottom flow channels is lower than top flow channels, and this bottom flow channels and top flow channels are all communicated with the another one piston cylinder at its rear portion; Between intake chamber and bottom flow channels, be provided with the 3rd suction valve 13, discharge between chamber and bottom flow channels and be provided with the 3rd expulsion valve 23; Between intake chamber and top flow channels, be also provided with the 4th suction valve 14, discharge between chamber and top flow channels and be also provided with the 4th expulsion valve 24.
Vertical Multi-cylinder dual reciprocating pump hydraulic-end of the present invention, only the side in this reciprocating pump hydraulic-end inner space arranges pump valve (i.e. four suction valves and four expulsion valves), pump valve is all placed in a side of piston 3, one side of pump valve is stayed space for maintenance in realization, facilitate in-plant repair and maintenance, easy to operate, thus shorten engineering time and reduce the labor intensity keeping in repair, time and labour saving.
Working principle:
3 to Fig. 5 by reference to the accompanying drawings, illustrates.In Fig. 4, two piston routing motions.The piston in left side rises, the piston on right side declines, piston cylinder, piston bottom volume increases, upper volume compression, the first suction valve 11 is opened, the first expulsion valve 21 cuts out, and the second suction valve 12 cuts out, and the second expulsion valve 22 is opened, the water of realizing in intake chamber enters piston bottom, and the hydraulic pressure people on piston top discharges chamber; The 3rd suction valve 13 cuts out simultaneously, and the 3rd expulsion valve 23 is opened, and the water of the piston bottom on right side enters discharge chamber, and the 4th suction valve 14 is opened simultaneously, and the 4th expulsion valve 24 cuts out, and the water in intake chamber enters the piston upper space on right side.Two piston movement opposite directions like this, constantly enter to discharge chamber by the hydraulic pressure in intake chamber, discharge chamber and are provided with outlet pipe, and the indoor high pressure water of discharge side is discharged by outlet pipe.
The above embodiment of the present invention is to be only explanation example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make on the basis of the above description other multi-form variation and changes.Here cannot give all mode of executions exhaustive.Every still row in protection scope of the present invention of apparent variation that technological scheme of the present invention amplifies out or change that belong to.
