Abstract
The utility model provides a water-feed pump tube body which resists scouring and corrosion, which is used to solve the shortcoming of the existing water-feed pump tube bodies. The water-feed pump tube body comprises a tube body, which is characterized in that the sealing combining face of the tube body is provided with a rustless steel welding layer. The water-feed pump tube body of the utility model satisfies the intensity requirement of the tube body after the tube body adopts alloyed steel and internal pile-up welding protection, which also satisfies the requirement of scour resistance and corrosion resistance of the tube body, prolongs the service span of pumps, and perfects the security and reliability design of pumps.
Description
Technical field
The utility model relates to the feed water pump technical field, specifically, relates to a kind of feed water pump cylindrical shell.
Background technique
The feed water pump cylindrical shell is the vitals of feed water pump, the water of high temperature, high pressure and high flow rate is for a long time flowing in its inside, interior because under the effect of high temperature, high pressure and high flow rate, sealing surface in the cylindrical shell and pump being imported and exported place such as pipe washes away and corrodes quite serious, washing away entail dangers to pump group for a long time normally moves, have a strong impact on the working life of pump group, also influence the normal power generation of power plant, increase the operating cost and the maintenance load of power plant widely.
The model utility content
The purpose of this utility model provides a kind of antiscour, corrosion resistant feed water pump cylindrical shell, to solve the deficiency of existing feed water pump cylindrical shell.
The technical problem that the utility model solved can realize by the following technical solutions:
A kind of feed water pump cylindrical shell comprises cylindrical shell, it is characterized in that: the sealed faying face in the described cylindrical shell is provided with the stainless steel layer.
In the utility model, in order further to strengthen the scour resistance of cylindrical shell, built-up welding stainless steel lining in the import of described cylindrical shell, outlet and tap are taken over.
In order to improve stainless working life, described stainless steel adopts Austenitic Stainless Steel.
Feed water pump cylindrical shell of the present utility model after cylindrical shell adopts alloyed steel to add inner built-up welding protection, has satisfied the requirement of strength of cylindrical shell, has satisfied the antiscour and the corrosion requirement of cylindrical shell again, the working life of having improved pump, the perfect Security and the reliability design of pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of feed water pump cylindrical shell, comprise cylindrical shell 1, sealed faying face heap in the cylindrical shell 1 has Austenitic Stainless Steel layer 2, built-up welding stainless steel lining 3 and 4 in the import 11 of cylindrical shell 1, outlet 12 and tap 13 are taken over, by special welding technique and welding procedure, guarantee that built-up welding and the bushing pipe in the cylindrical shell do not washed away, corrodes and do not flake.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
