Abstract
The utility model provides a technology is produced, wastes time and energy that compressor housing, the problem that solve is current compressor housing use the whole cast to the waste has been caused to the material, the utility model provides an at the inside stainless steel runner that is provided with of casing, the stainless steel runner is including the import runner and export the runner, and the runner mouth is the toper layer with the connecting portion of casing, the toper layer is that the austenite stainless steel welding is packed. The utility model has the advantages that through at the inside sheet metal that adopts partial stainless steel of casing, avoided needing whole schemes that adopt the stainless steel casing because of medium corruptions, great reduction manufacturing cost.
Description
Technical field
The utility model belongs to Compressor Technology field, particularly a kind of corrosion resistant centrifugal compressor casing.
Background technology
Centrifugal compressor is at ethylene unit, and in the numerous industries of oil refining, the petrochemical industries etc. such as Butyl Rubber, natural gas liquefaction, as its " core " equipment, the long-term operation of centrifugal compressor is " heart " that ensures whole device long-term operation. And casing is as most important part in all parts of compressor, the problem of most important thing when its safety and stability, corrosion-resistant, reliable intensity in compressor design. Once compressor case is corroded, dielectric leakage, unit is unstable, causes compressor parking, whole process units to stop production, and brings huge economic loss to enterprise.
The situation that cannot carry out surface spraying that existing compressor housing causes due to stainless sensitive temperature problem and special construction thereof, the situation that has caused housing to need monoblock cast etc. to waste time and energy.
Summary of the invention
The purpose of this utility model is to provide a kind of corrosion resistant centrifugal compressor casing.
The purpose of this utility model is achieved in that it comprises: housing, is characterized in that: enclosure interior is provided with stainless steel runner; Described stainless steel runner comprises inlet channel and outlet flow, and the connecting portion of runner mouth and housing is taper layer, and described taper layer is austenitic stainless steel weld filler.
Between stainless steel runner and housing base, be also provided with taper layer.
The utility model has the advantages that: by the inner stainless thin plate of part that adopts of casing, avoided needing all to adopt because of dielectric corrosion the scheme of stainless steel casing, reduced greatly manufacturing cost.
The utility model, by adopting various material welding casing, has avoided adopting the scheme of monoblock cast stainless steel casing, has reduced greatly the duration, in advance for user provides qualified product, so that user goes into operation as early as possible, has obtained significant economic benefit.
Brief description of the drawings
Fig. 1 is structural representation sketch of the present utility model.
The utility model is described in further detail by example below in conjunction with accompanying drawing; but following example is only the utility model example wherein; do not represent the right protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claims.
Detailed description of the invention
Example 1
Referring to Fig. 1, enclosure interior is provided with stainless steel runner 1; Described stainless steel runner comprises inlet channel 2 and outlet flow 3, and the connecting portion of runner mouth and housing is taper layer 4, and described taper layer is austenitic stainless steel weld filler.
Between stainless steel runner and housing base, be also provided with taper layer. Above-mentioned stainless steel runner is to be fixed with stainless steel substrates on the inwall of inlet channel and outlet flow, and it is carried out to the integral solder of connecting portion.
Adopt the design of stainless steel and steel alloy combination. By the method for the long heat treatment of low temperature and vibration stress-removal, avoid stainless sensitive temperature, so part runner has adopted the material of austenitic stainless steel, not only save the expensive of spraying, more solved many because reasons in structure cannot realize the problem of spraying.
Claims (2)
1. a compressor housing, it comprises: housing, is characterized in that: enclosure interior is provided with stainless steel runner; Described stainless steel runner comprises inlet channel and outlet flow, and the connecting portion of two runner mouths and housing is taper layer, and described taper layer is austenitic stainless steel weld filler.
2. a kind of compressor housing according to claim 1, is characterized in that: between stainless steel runner and housing base, be also provided with taper layer.
