Description
Technical field
The present invention relates to a kind of pump, more particularly, to a kind of wear-resistant sand suction pump.
Background technology
Sand suction pump is made up of pump case, pump cover, impeller, pump shaft and bearing assembly etc., and pump cover connects before being generally divided into and connect with two, its
In positioned at the pump cover of sand inlet side connection sand inlet tube be referred to as before connect, the pump cover of opposite side connection bearing block is referred to as two and connect；Also have
Some sand suction pumps will preceding connect and are integrally formed with pump case, and pump cover now just only connects comprising one two.For the ease of processing,
Connect, two connect before of the prior art, impeller is all made of using being easy to machining but the poor grey iron of wearability, it is impossible to be long
The impact of long resistance mortar, is prone to wear out, is broken so that the service life of existing sand suction pump is very short.
The content of the invention
Technical problem：In view of the deficienciess of the prior art, a kind of wear-resistant, impact resistance is provided, the suction of service life length
Husky pump.
Technical scheme：Wear-resistant sand suction pump provided by the invention, including pump case, two connect, impeller and pump shaft, impeller include impeller
Main body and it is located therein the core wheel for installing pump shaft, two connect and connect main body and the water tight compartment being located therein including two；Two
The edge for connecing main body is provided with some pump case connecting screw holes, described pump case main body rear port be provided with position, quantity with it is described
Two connect the position of pump case connecting screw hole in main body, quantity corresponding nut or bolt, described two connect and are set on the outside of main body
There is bearing block connecting elements；Its innovation is that described two connect main body is cast using antifriction cast iron, and water tight compartment uses other
It can be manufactured with the ferroalloy of machining and be cast into two and connect in main body.Other described can be able to be with the ferroalloy of machining
Common grey iron, or steel, common spheroidal graphite cast-iron etc..It is described be cast into be it is pre-buried be cast into, can directly use machine-shaping
Water tight compartment be cast into two and connect in main body, can also be connect being first cast into two for unformed core iron in main body, then carry out further
Processing.Sand suction pump of the prior art, in order to facilitate the processing of water tight compartment, to including two connect main body including whole two connect and all adopt
Manufactured with the grey iron for being easy to machining so that two wearabilities connect are poor.The present invention breaches the constraint of conventional art,
The different parts connect to two are manufactured using different materials, impact larger two and connect main body using antifriction cast iron to bearing mortar
Casting, it is pointed to two and connects the ferroalloy manufacture that middle part is easy to machining by the less water tight compartment of mortar impact using other,
Solve the processing problems of water tight compartment while the wearability that raising two connects.
The present disclosure applies equally to preceding connect the sand suction pump with pump case main body split settings, now, the present invention includes pump case master
Body and before connect, some pump case connecting screw holes also are provided with the edge for preceding connecing main body, are provided with the front port of described pump case main body
Position, quantity with it is described before nut or bolt that to connect the position of pump case connecting screw hole in main body, quantity corresponding；Before described
The outside for connecing main body is provided with sand inlet tube connecting elements.
In order to further improve the overall wear resistence of sand suction pump, all easily frayed parts of handle of the present invention are all using anti-
Cast iron manufacture is ground, i.e.,：Described impeller bodies, pump case main body and before connect main body and cast using antifriction cast iron, the pump case master
The nut or bolt of the forward and backward two-port of body are cast into pump case main body, and described core wheel uses other can be with the ferroalloy of machining
Manufacture and be cast into impeller bodies, described sand inlet tube connecting elements be sand inlet tube adpting flange or it is some be cast into before connect main body
Nut or bolt, described bearing block connecting elements be bearing block adpting flange or it is some be cast into two nuts for connecing main body or
Bolt.Because being difficult to machining on antifriction cast iron, so, pump case main body is cast into, preceding main body connect, two connects main body
Nut, the female nut of tool can be used to be cast into, can also first be cast into by the use of bloom as core iron, then be bored again on core iron
Hole, tapping are into nut；Equally, be cast into pump case main body, it is preceding connect main body, two connect the bolt of main body, can be directly using having screw thread
Bolt be cast into, first can also be cast into the core iron of non-threaded, then again mantle fiber into bolt.Used bearing block adpting flange
Or sand inlet tube adpting flange, the one-shot forming in casting, without machining.
In order to reduce the cost of the wear-resistant sand suction pump of the present invention, described antifriction cast iron can select white iron, described other
Grey iron or spheroidal graphite cast-iron can be selected with the ferroalloy of machining.
Further, in order to improve the toughness of impeller, prevent from being broken when impeller from being impacted by stone, it is described
Impeller bodies preferably use high chromium white antifriction cast iron.
Beneficial effect：Firstly, since the two of sand suction pump of the present invention connect main body and antifriction cast iron is respectively adopted and can in water tight compartment
Manufactured with the ferroalloy of machining, solve caused by the contradiction of wearability and machinability two and connect not wear-resisting difficulty
Topic；Secondly, the method that core wheel is cast into high chromium white antifriction cast iron impeller bodies used on impeller, impeller is greatly improved
Toughness, solve the problems, such as to be easy to brittle failure when impeller is impacted by stone, improve the service life of sand suction pump.In addition, in pump
Shell main body, it is preceding connect with the two cast-in bolts or nut for connecting use, and connect two, the preceding adpting flange for connecting design,
While improving sand suction pump wear resistence, being reliably connected for sand suction pump is realized with simple structure, simplifies production process.
