Abstract
The utility model discloses an L-shaped hydraulic end of reciprocating pump, which comprises an outlet hydraulic cylinder, an inhaling hydraulic cylinder and an outlet pipeline, wherein the outlet pipeline is arranged in front of the outlet hydraulic cylinder and above the inhaling hydraulic cylinder crucially, thereby overcoming the defect of the prior L-shaped hydraulic end, and ensuring the easy disassembly and installation and reliable seal of the outlet hydraulic cylinder.
Description
The utility model relates to a kind of " L shaped " fluid end of reciprocating pump.
" L shaped " fluid end of reciprocating pump has following two kinds both at home and abroad at present:
The one, to discharge between the fluid cylinder and overlap perforation with weak point, discharge conduit is installed in the side of discharging fluid cylinder.Have the characteristics of compact structure, but facts have proved, discharge the dismounting difficulty of fluid cylinder.
The 2nd, discharge conduit is installed in the back side (frame front top) of discharging fluid cylinder.This scheme has and mounts and dismounts advantage easily.This scheme is connected with bolt between frame but be not easy to discharge fluid cylinder, if just can't be adopted when needing with the connecting bolt that will be provided with fluid cylinder in frame front wallboard top.
The purpose of this utility model is the defective that overcomes above " L shaped " fluid end structure, and novel " L shaped " fluid end that a kind of dismounting fluid cylinder is convenient, sealing is reliable, discharge conduit is arranged on the front (sucking the top of fluid cylinder) of discharging fluid cylinder is provided.
The purpose of this utility model is achieved like this, and the discharge fluid cylinder (1) of this " L shaped " fluid end links by bolt, nut and packing ring (5) frame with pump; Suck fluid cylinder (2) and discharge fluid cylinder (1), and be connected as one by bolt, nut (6) with seam (A) location; Discharge conduit (3) connects by bolt, nut (4) with discharge fluid cylinder (1).Its special way is: discharge conduit (3) is arranged on the front (B) of discharging fluid cylinder (1), the top that sucks fluid cylinder (2).
The valve gap of discharging fluid cylinder (1) and sucking on the fluid cylinder (2) has a style of one's own with box thread and fluid cylinder itself.Also can and suck on the fluid cylinder (2) and be provided with bonnet flange (12) respectively, and connect by bolt, nut (13) at discharge fluid cylinder (1).
Outstanding advantage of the present utility model is under the Bolt Connection intensity and convenience condition that guarantee to discharge between fluid cylinder (1) and frame, and the installation and removal of discharging fluid cylinder (1) are convenient, and sealing is reliable.
Description of drawings:
Fig. 1 is structure sectional view of the present utility model (valve gap and a fluid cylinder one).
Fig. 2 is a structure sectional view of the present utility model (having bonnet flange).
Below in conjunction with drawings and Examples the utility model is described in further detail.
Embodiment 1: the structure sectional view as shown in Figure 1, a kind of " L shaped " fluid end of reciprocating pump, form by the bolt and nut (4,5,6,9) of discharging fluid cylinder 1, suction fluid cylinder 2, discharge conduit 3, wear-resisting dish 7, cylinder sleeve flange 8, cylinder sleeve gland 10, cylinder sleeve 11 and connection usefulness, discharge conduit 3 is arranged on the front of discharging fluid cylinder 1, sucks the top of fluid cylinder 2.Discharge fluid cylinder 1 and suck between the fluid cylinder 2 and locate with seam (A).In addition, be provided with wear-resisting dish 7 between cylinder sleeve 11 and discharge fluid cylinder 1, wear-resisting dish 7 and cylinder sleeve flange 8 connect by bolt, nut 9, and cylinder sleeve 11 is fastening by gland (10).The setting of wear-resisting dish can be protected the discharge fluid cylinder, prevents that the thorn of cylinder liner packing ring from losing and damage discharge fluid cylinder.The setting of cylinder sleeve flange 8 and gland 10 can make things convenient for the installation and removal of cylinder sleeve, and has the lightweight advantage of part such as lifting cylinder sleeve etc.The valve gap of discharging fluid cylinder 1 and sucking on the fluid cylinder 2 has a style of one's own with box thread and fluid cylinder itself.Characteristics with compact structure.
Embodiment 2: the structure sectional view is provided with bonnet flange 12 respectively as shown in Figure 2 on discharge fluid cylinder 1 and suction fluid cylinder 2 in embodiment's 1 structure, and connect by bolt, nut 13.Have and discharge fluid cylinder 1 and suck the advantage that fluid cylinder 2 is easy to process.
Claims (5)
