Abstract
The utility model discloses an overall plastic horizontal centrifugal pump with high performance and corrosion resistance, which is characterized in that a pump casing, a pump cover, a mechanical seal seat and a mechanical seal gland are all made from polyvinylidene fluoride plastic and are formed at one shot by molds; the steel frame of an impeller is coated with polyvinylidene fluoride plastic, the general thickness of which is no less than 20mm; a rotating seat at the mechanical seal seat and the impeller are integrated into one piece; the plastic pump casing is surrounded by a nodular cast iron housing. The utility model is advantageous in that the corrosion resistance is good; strength is enhanced; leakage points of the mechanical seal are reduced; the service life of the plastic centrifugal pump is greatly increased; the centrifugal pump can be applied in various bad environments.
Description
Technical field
The utility model relates to a kind of centrifugal pump, particularly relates to a kind of high performance corrosion-proof all-plastic horizontal centrifugal pump.
Background technique
The occasion that adds conveying severe corrosive fluids such as acid in iron and steel, oil, chemical industry, papermaking, environmental protection, non-ferrous metal, municipal sewage treatment, mine, pickling, the metal centrifugal pump is because can be corroded, obviously can't use for a long time, the steel lining plastic centrifugal pump is often because reasons such as impurity cause working life very short, therefore in this class occasion, need to consider the corrosion resistance of centrifugal pump usually.
The model utility content
The purpose of this utility model is to solve the deficiency of existing centrifugal pump, and a kind of all-plastic centrifugal pump that is suitable for various rugged environment, corrosion resistance height, longer service life is provided.
The technological scheme that the utility model solution prior art deficiency is taked is: a kind of all-plastic horizontal centrifugal pump, comprise pump case, pump cover, impeller, mechanical sealing base, mechanical seal cover, it is characterized in that: pump case, pump cover, mechanical sealing base, mechanical seal cover all adopts polyvinylidene fluoride plastics mould disposal pressed moulding, impeller includes the steel skeleton, the appearance profile of this skeleton is less than the impeller appearance profile, disposable mold pressing coats the polyvinylidene fluoride plastics outside the steel skeleton, and the average thickness of plastics is no less than 20mm, definitely can satisfy under all kinds of bad working environments and use; Adopt the special construction mechanical seal of independent development, the rotating seat at mechanical sealing base place and impeller are integral structures, by the disposable compression molding of mould, have increased intensity, reduced the leakage point of mechanical seal, made increase greatly the service life of plastic centrifugal pump.
Further, the spheroidal graphite cast iron shell is arranged, guarantee that in a single day pump is subjected to accidental shock, can effectively protect and be unlikely and damage pure plastics pump case, cause danger in the outsourcing of polyvinylidene fluoride plastics pump case.
The beneficial effects of the utility model are: centrifugal pump of the present utility model had both had excellent corrosion resisting performance, can overcome simultaneously the defective of common steel lining plastic centrifugal pump again, increased intensity, reduced the leakage point of mechanical seal, made increase greatly the service life of plastic centrifugal pump.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the mechanical seal place enlarged view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
A kind of all-plastic horizontal centrifugal pump of the utility model as shown in Figure 1, pump case 3 are the disposable compression moldings of mould of whole polyvinylidene fluoride (PVDF) fluoroplastic, and average thickness is no less than 20mm; Pump cover 4 is the disposable compression moldings of mould of whole polyvinylidene fluoride (PVDF) fluoroplastic, and average thickness is no less than 20mm; Impeller 1 includes the steel skeleton, and the appearance profile of this skeleton is less than the impeller appearance profile, and disposable mold pressing polyvinylidene fluoride (PVDF) fluoroplastic outside Steel Skeleton wrap polyvinylidene fluoride (PVDF) fluoroplastic outward entirely with Steel Skeleton, and average thickness is no less than 20mm; Mechanical seal cover 5 is the disposable compression moldings of mould of whole polyvinylidene fluoride (PVDF) fluoroplastic, and average thickness is no less than 20mm.Centrifugal pump has good anti-corrosion.
At pure plastics pump case outsourcing spheroidal graphite cast iron metal shell 2, guarantee that in a single day pump is subjected to accidental shock, can effectively protect and be unlikely and damage pure plastics pump case, cause danger.
The enlarged view at mechanical seal 6 places as shown in Figure 2, the special construction at I place among the figure is that rotating seat and impeller are made of one, and by the disposable compression molding of mould, has increased intensity, has reduced the leakage point of mechanical seal 6, increase service life greatly.
Claims (2)
1. all-plastic horizontal centrifugal pump, comprise pump case, pump cover, impeller, mechanical sealing base, mechanical seal cover, it is characterized in that: pump case, pump cover, mechanical sealing base, mechanical seal cover all adopts polyvinylidene fluoride plastics mould disposal pressed moulding, impeller includes the steel skeleton, the appearance profile of this skeleton is less than the impeller appearance profile, disposable mold pressing coats the polyvinylidene fluoride plastics outside the steel skeleton, and the average thickness of plastics is no less than 20mm, the rotating seat at mechanical sealing base place and impeller are integral structures, by the disposable compression molding of mould.
