Abstract
The utility model relates to the improvement of a corrosion resistant and abrasion resistant centrifugal pump, particularly to the improvement of the abrasion resistant end surfaces of a front pump cover and a back pump cover of the centrifugal pump. The utility model is characterized in that a pump body is composed of the front pump cover, an entire whorl shell with a flow path and the back pump cover which are axially assembled. The inner sides of the front pump cover and the back pump cover are provided with entire abrasion resistant baffles combined with the pump covers in separation. The service life of the corrosion resistant centrifugal pump delivering a medium containing granules is prolonged. When the abrasion resistant baffles are abraded, the abrasion resistant baffles can be directly changed by loosening the front pump cover and the back pump cover, and the entire front pump cover and the back pump cover are not needed to be changed. The maintenance cost is greatly saved, and the disassembly is simple.
Description
Technical field
Model utility is about the improvement to the anticorrosive anti-wear centrifugal pump, relates in particular to the improvement of the wear-resisting end face of the forward and backward pump cover of centrifugal pump.
Background technique
When the corrosion-proof type centrifugal pump contains the particle erosion medium in conveying, because of the impeller high speed rotating drives the rotation of pump chamber inner fluid, pump cover inner side end before and after the high speed rotating of solid-phase material washes away, thereby more easy to wear than other positions, therefore the wear resistance of forward and backward pump cover has a strong impact on working life of centrifugal pump.And known corrosion-proof type centrifugal pump only is at overcurrent position lining one deck anticorrosive coat plastics or by the overall plastic pump housing of making for example, and this plastic layer had both been made anticorrosive coat and used, simultaneously double as wearing layer again.Because manufacture difficulty factor (pump housing is a shaped body), plastic layer is generally not really wear-resisting, therefore very easily wearing and tearing.For improving the wear resistance of centrifugal pump cover, Chinese patent 01237509 discloses a kind of in the front pump cover inboard and the centrifugal pump front pump cover of choma position combined tessera wear insert, increases the service life with this.Yet because this inlaying with pump cover is combined into one, in case after the wear insert concentrated wear, still need to change whole front pump cover, maintenance cost is relatively still bigger, secondly, the rear pump cover inboard of pump also is a position more easy to wear, does not add wearing layer, still influences the raising in working life of whole centrifugal pump.Therefore still having is worth improved place.
Summary of the invention
The purpose of model utility is to overcome the deficiency of prior art, provide a kind of not only can significantly improve to carry contain the working life of granule medium centrifugal pump, and have more low-dimensional and accomplish this and the good anticorrosive anti-wear centrifugal pump of versatility.
The model utility purpose realizes, the main improvement is by the forward and backward pump cover inner side end at the corrosion-proof type centrifugal pump, the one wear-resisting baffle plate of being made by high-abrasive material that can separate with pump cover dismounting is set, even wear-resisting like this baffle plate in use meets wearing and tearing, also only need this wear-resisting baffle plate of pump dismounting and change, and do not need to change whole pump cover, maintenance cost is reduced greatly, because wear-resisting baffle plate and pump cover are can deciliter structure, therefore can prepare the wear-resisting baffle plate that different high-abrasive materials are arranged, matched according to conveying material, enlarged the pump application area.Specifically, model utility anticorrosive anti-wear centrifugal pump is characterized in that the said pump housing is axially combined by front pump cover, the whole volute of band runner and rear pump cover, and there is the whole wear-resisting baffle plate with pump cover split combination said forward and backward pump cover inboard.
The wear-resisting baffle plate of model utility according to Environmental Conditions, can be selected various different high-abrasive materials for use, as making such as abrasion resistance alloy, abrasive rubber, wear-resistant plastic, wear-resistant ceramic, sytulles.Model utility corrosion-proof type centrifugal pump, a kind of better mode helps improving the bulk strength and the static seal performance of pump for adopting steel body lining structure.
Model utility is owing to axially be divided into front pump cover, the whole volute of band runner, rear pump cover three assemblying structures with plastic-lining centrifugal pump, and install split additional in front pump cover and rear pump cover inboard and make up removable wear-resisting baffle plate assembly, not only improved the working life of corrosion-proof type centrifugal pump when conveying contains granule medium greatly, and after wear-resisting baffle plate wearing and tearing, only need unclamp forward and backward pump cover and directly change wear-resisting baffle plate, and need not change whole forward and backward pump cover, dismantle also simple.Forward and backward pump cover is provided with the wear-resisting baffle plate of composite structure, not only significantly improved corrosion-proof type centrifugal pump whole service life, and saved maintenance expenses greatly, and can change corresponding wear-resisting baffle plate at any time according to the fed sheet of a media needs, a pump is adapted to carry multiple medium purposes.Therefore because wear-resisting baffle arrangement is simple, help moulding in addition, makes also easyly, can adapt to multiple high-abrasive material making.
Description below in conjunction with two indefiniteness embodiments further specifies model utility.
Description of drawings
Fig. 1 adopts the unshrouded impeller structural representation for model utility first embodiment.
Fig. 2 adopts the double shrouded wheel structural representation for model utility second embodiment.
Embodiment
Embodiment 1: referring to Fig. 1, the anticorrosive anti-wear centrifugal pump is combined by front pump cover 1, the whole volute 5 of band runner and rear pump cover 9, and pump overcurrent part lining has corrosion resistant plastic layer 6.Whole volute both side ends has the positioning step of bending, forward and backward pump cover inboard has high-abrasive material to make respectively, wear-resisting baffle plate 2 of umbrella shape funnel structure that coincide with unshrouded impeller 7 conical surfaces and the wear-resisting baffle plate 8 of ring-type that coincide with the impeller rear end, wear-resisting baffle plate longitudinal end have cooperate with the volute positioning step turn up positioning step 4, make wear-resisting baffle plate location.For improving the sealability of junction plane, between each adjacent bond face packing ring 3 is arranged.Forward and backward pump cover compresses by fastening screw trip bolt and the combination of whole volute.After the wear-resisting baffle plate wearing and tearing, fastening screw trip bolt before and after only need unclamping, the wearing plate that just can take out in it is changed.
Embodiment 2: referring to Fig. 2, as embodiment 1, centrifugal pump adopts double shrouded wheel, and the wear-resisting baffle plate 2 of front pump cover inboard can be made into the funnel-shaped structure of end face almost plane.
The said corrosion-proof type centrifugal pump of model utility is meant that pump housing overcurrent position is made of high molecule plastic or fiber glass resin, comprises overall plastic or all-glass fibre reinforced plastic centrifugal pump casing and mould, serve as a contrast rubber or lining glass steel shell at overcurrent position lining.
