Abstract
The utility model provides an impeller wear ring of a petroleum chemical process pump. The impeller wear ring is fixedly sleeved on an impeller of the petroleum chemical process pump. A spiral groove is formed in the impeller wear ring along the outer circumference of the same. By improving the impeller wear ring on the basis of an existing technology and arranging the spiral groove in the impeller wear ring, interstage leakage of the petroleum chemical process pump is greatly reduced, and efficiency of the petroleum chemical process pump is improved at the same time.
Description
Technical field
The utility model belongs to the petrochemical process pump field, is specifically related to a kind of impeller port ring of petrochemical process pump.
Background technique
Along with the rapid growth in domestic construction, oil, petrochemical industry, environmental protection market, Chinese pump has already welcome powerful life, we can say that the market space of Chinese sustainable growth already brings spring for Chinese pump.With regard to only at regard to the petroleum chemical industry, in the working ability of the oil refinery list covering device of China before 2003 generally about 5,000,000 tons/year, but along with China's petrochemical industry develops rapidly, it is main petroleum refining device that the oil refining apparatus of China has developed into 1,000 ten thousand tons of/year scales, even 2,000 ten thousand tons/year oversized device.In addition China just will build a collection of large-scale oil refining more than 1,000 ten thousand tons/year during " 12 " successively, large-scale ethene more than 1,000,000 tons/year, mega project such as large-scale PTA more than 1,000,000 tons/year, the construction of these mega projects, will drive the maximization of the device of downstream project, and the maximization of device, the maximization of its corresponding corollary equipment of inevitable requirement.With regard to pump, just need bigger flow, higher lift, bigger air horsepower, multistage radially subdivision petrochemical process pump (WD type pump) is exactly to succeed in developing under this demand.Impeller port ring is a critical component of petrochemical process pump, impeller port ring also is wear ring, and it is embedded on impeller and the pump case, and main effect is sealing medium (prevents from exporting medium and get back to entrance), also can increase simultaneously the wear resistance of impeller and housing, the Economy that increased pump.But impeller port ring of the prior art generally all adopts simple seal ring to realize, sealing effect is not very desirable.
The model utility content
The utility model provides a kind of impeller port ring that reduces the petrochemical process pump of inter-stage leakage at above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of impeller port ring of petrochemical process pump, described impeller port ring are fixedly set on the impeller of petrochemical process pump; It is characterized in that described impeller port ring is provided with spiral chute.
Further setting of the present utility model is that described spiral chute is along the excircle setting of impeller port ring.
Further setting of the present utility model is that described impeller port ring is connected by bolt with impeller.
The impeller port ring of petrochemical process pump described in the utility model improves on the basis of existing technology, by at impeller port ring spiral chute being set, makes the inter-stage leakage of pump significantly reduce, and has improved the efficient of pump simultaneously.
Description of drawings
Fig. 1 is that the impeller port ring of petrochemical process pump described in the utility model is at the structural drawing of the state of use.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As described in Figure 1, the utility model provides a kind of impeller port ring 1 of petrochemical process pump, and described impeller port ring 1 is fixedly set on the impeller 2 of petrochemical process pump; Be provided with spiral chute 3 along its excircle on the impeller port ring 1.Impeller port ring 1 is connected by bolt 4 with impeller 2, and its face that is provided with spiral chute 3 cooperates with pump housing choma 5, so can reduce inter-stage and leak.
The above is preferred embodiment of the present utility model, and all equivalent variations of doing according to the utility model claim all should belong to protection domain of the present utility model.
Claims (3)
1. the impeller port ring of a petrochemical process pump, described impeller port ring is fixedly set on the impeller of petrochemical process pump; It is characterized in that described impeller port ring is provided with spiral chute.
2. the impeller port ring of petrochemical process pump according to claim 1 is characterized in that, described spiral chute is along the excircle setting of impeller port ring.
