Abstract
The utility model relates to a full lining split-flow type double-layer shell oil slurry pump, and belongs to the field of centrifugal pumps. The full lining split-flow type double-layer shell oil slurry pump comprises an inner shell component arranged in an outer shell, wherein the inner shell component is composed of a pump body, an impeller, a pump cover and other components which are matched, the technical key points are that a lining matched with the pump body is arranged in the pump body, a lining matched with the pump cover is arranged in the pump cover, the pump cover lining is fixed into a whole with the pump cover through a screw, the pump lining is pressed between the pump body and the pump cover. After the utility model improves the existing technique, since a double shell structure is adopted, the lining is additionally arranged in the pump body and the pump cover, simultaneously, the pump adopts the impeller of full-open type partial split-flow structure, thereby the full lining split-flow type double-layer shell oil slurry pump has the advantages of simple structure, stable and reliable operation and strong anti-abrasion ability.
Description
Technical field
The utility model belongs to the centrifugal pump field, specifically is a kind of Full lining part flow pattern double Shell oil mud pump.
Background technique
Catalytic cracking unit is the pillar of current petroleum refining industry, its processing technology that adopts be with the heavy in the oil partly by the effect of catalyzer, under uniform temperature, pressure condition, produce light-end products through series of chemical.The conveying that oil mud pump is exclusively used in high temperature in the oil refinery fluid catalystic cracking flow process and contains the catalyst solid granule medium designs.Oil mud pump mainly is classified as three classes at present: the first kind is the technological process pump that does not add protective measure, generally adopts stainless steel structure; Second class is through improved technological process pump, the internals of pump have adopted hard coat, mainly comprise the coating of diffusion coating, tungsten carbide coating and nickel, chromium, cobalt, boron all cpds etc., reach and significantly improve wetted surfaces intensity and hardness, improve the purpose of mechanical property; The 3rd class is the double shrouded wheel oil mud pump of Full lining, adopts removable casting hard metal lining.The internals of pump (spiral case lining and impeller) all adopt cast structure, and with the erosion resistant high-chromium alloy part of bolton.Owing to participate in the wearing and tearing that catalyst for reaction easily causes oily equipment, therefore how to improve the antiwear property of equipment, especially how to prolong that be the matter of utmost importance that present petroleum refining industry needs to be resolved hurrily the working life of oil mud pump in the slurry service, bivalve body oil mud pump can address the above problem preferably, but be subjected to the influence of existing structure, still had the deficiency of abrasion resistance properties difference.
The model utility content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and prior art is improved, the Full lining part flow pattern double Shell oil mud pump that provide a kind of simple in structure, stable, abrasive resistance is strong.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is a kind of Full lining part flow pattern double Shell oil mud pump, comprise the inner housing assembly that is arranged in the frame, the inner housing assembly is made of the pump housing, impeller, pump cover and other assembly that matches, the present technique main points are to be provided with in the described pump housing lining that mates with the pump housing, lining with the pump cover coupling is set in the pump cover, the pump cover lining fastens as one by screw and pump cover, and pump housing lining is fitted between the pump housing and the pump cover.
Like this; the pump housing, pump housing lining, pump cover and the pump cover lining that constitutes the inner housing assembly all can be separately or a complete set of replacing; also can according to wear extent adjust the impeller axial position or again the reconditioning inner housing solved difficult problems such as prior art mono-hull oil mud pump life-span weak point, poor reliability, maintenance and idleness expense height to prolong its working life.
More firm for the pump housing and pump housing lining are installed, pump housing lining also fastens as one by the screw and the pump housing.
Described impeller adopts full-open type part flow structure, reduced from waterpower and to have contained of the wearing and tearing of catalysed particulate medium blade, the impeller inlet diameter is bigger, has good anti-cavitation performance, blade length is alternate, and the vane channel spaciousness can be avoided solid obstructions such as coking, except rotor axial power in a basic balance, also can reduce the pressure of leakage rate and reduction machine sealing chamber.Pump is behind long-play, and when gap between the dynamic and static component of impeller increased, performance that also can kept stable had improved the reliability of pump.
In sum, after the utility model improves prior art, owing to adopted double-shell structure, and all installed lining in the pump housing and pump cover additional, simultaneously, this pump adopts the impeller of full-open type part flow structure, therefore have simple in structure, stable and reliable operation, the advantage that abrasion-resistance is strong.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model structural representation.
Fig. 2: the blade wheel structure schematic representation of full-open type part flow structure.
Embodiment
As shown in Figure 1, this Full lining part flow pattern double Shell oil mud pump, comprise the inner housing assembly that is arranged in the frame, the inner housing assembly is made of the pump housing 1, impeller 3, pump cover 4 and other assembly that matches 6, the present technique main points are to be provided with in the described pump housing 1 lining 2 that mates with the pump housing 1, the lining 5 that mates with pump cover is set in the pump cover 4, and pump cover lining 5 fastens as one by screw and pump cover 5, and pump housing lining 2 is fitted between the pump housing 1 and the pump cover 4.
Like this; the pump housing 1, pump housing lining 2, pump cover 4 and the pump cover lining 5 that constitutes the inner housing assembly all can be separately or a complete set of replacing; also can according to wear extent adjust the impeller axial position or again the reconditioning inner housing solved difficult problems such as prior art mono-hull oil mud pump life-span weak point, poor reliability, maintenance and idleness expense height to prolong its working life.
More firm for the pump housing 1 and pump housing lining 2 are installed, pump housing lining 2 fastens as one by the screw and the pump housing 1.
The full-open type part flow structure that described impeller 3 adopts as shown in Figure 2, reduced from waterpower and to have contained of the wearing and tearing of catalysed particulate medium blade, the impeller inlet diameter is bigger, has good anti-cavitation performance, blade length is alternate, the vane channel spaciousness, can avoid solid obstructions such as coking, except rotor axial power in a basic balance, also can reduce the pressure of leakage rate and reduction machine sealing chamber, behind long-play, when the gap increases between the impeller sound component, performance that also can kept stable has improved the reliability of pump.
In sum, after the utility model improves prior art, owing to adopted double-shell structure, and all installed lining in the pump housing and pump cover additional, simultaneously, this pump adopts the impeller of full-open type part flow structure, therefore have simple in structure, stable and reliable operation, the advantage that abrasion-resistance is strong.
