Description
Technical field
The utility model provides a kind of assembly, is specifically related to a kind of suction line fluid end assembly.
Background technique
The appropriate design of the suction line in petroleum drilling and mining equipment is particularly important.But due to the restriction of traditional concept, project planner's convection current send the configuration of system pipeline to pay little attention to, usually in order to effectively reduce floor space, special appropriate design flow pattern not being done to suction line, having a strong impact on the normal use of pump.Can lift of pump be reduced when liquid stream prewhirls turn to identical with impeller, lift of pump and power can be increased when liquid stream is prewhirled with during impeller counterturn, cause driving machine to transship and stop or damage.
The more important thing is that improper air or the water vapour of will causing of suction line design is carried secretly to enter in pump and caused cavitation, produce and vibrate, and make pump depart from equilibrium position.Cavitation can cause impeller heavy wear, and departs from equilibrium position and can produce the slight eccentric rotary of axle, the bearing of Final wear point pump and sealing, causes stopping.Therefore, the appropriate design particular importance of suction line.
Summary of the invention
The utility model provides a kind of suction line fluid end assembly, utilize suction line fluid end assembly of the present invention designing requirement to manufacture suction line fluid end assembly, the degree of rational design pump intake straightway and diameter, pump is made to be in normal working, improve working efficiency, extend the working life of pump.
Technical solution of the present utility model is: this suction line fluid end assembly comprises blank flange, flange, flange I, base plate, flange III, short circuit, steel pipe, gusset, gusset, short circuit, short circuit, O RunddichtringO, bolt, nut, installs blank flange at the two ends of steel pipe.
In the utility model suction line fluid end assembly, the length of straightway is 7 times of ingress diameter.
In the utility model suction line fluid end assembly, be 1/4 of diameter of steel tube with the center of the perpendicular eccentric ingress of short circuit.
The utility model beneficial effect is: structure is simple, reasonable in design, without cavitation, friction, safe and reliable, long service life.
Accompanying drawing explanation
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the utility model structural representation.
In Fig. 1, Fig. 2, Fig. 3, Fig. 4: 1, blank flange 2, flange 3, flange I 4, base plate 5, flange III 6, short circuit 7, steel pipe 8, gusset 9, gusset 10, short circuit 11, short circuit 12, O RunddichtringO 13, bolt 14, nut
Embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, this suction line fluid end assembly comprises blank flange 1, flange 2, flange I3, base plate 4, flange III5, short circuit 6, steel pipe 7, gusset 8, gusset 9, short circuit 10, short circuit 11, O RunddichtringO 12, bolt 13, nut 14, installs blank flange 1 at the two ends of steel pipe 7.
In the utility model suction line fluid end assembly, the length of straightway is 7 times of ingress diameter.
In the utility model suction line fluid end assembly, be 1/4 of diameter of steel tube with the center of the perpendicular eccentric ingress of short circuit 6.
The utility model beneficial effect is: structure is simple, reasonable in design, without cavitation, friction, safe and reliable, long service life.
