The periphery of the rotor body (1) is provided with a plurality of blades. The blades are characterized in that: each blade is provided with a through hole (3) or a sealed empty chamber (4). The rotor of the double rotor pump has characteristics of light weight, raw material saving, small frictional coefficient, avoidances of pump body scoring, pump cover scoring and rotor scoring, and is easy to be cleaned thoroughly.
Description
Technical field:
The present invention relates to cammingly birotor pump technical field, specifically is a kind of rotor of cammingly birotor pump.
Background technique:
The cammingly birotor pump is a kind of high-performance transfer pump, is main material transfer equipment in the chemical-process technology.Its main feature is to be fit to carry the higher and mordant medium of stickiness, or does not allow the medium of pollution.As shampoo, shower cream, paper pulp, machine oil, lubricant oil, syrup, medicine emulsion or the like.It mainly is made up of the pump housing that has import and export, pump cover, main shaft, countershaft, cam follower and transmission part and mechanical seal parts.Working principle: main shaft and countershaft drive two rotations that cam follower is reverse each other respectively, and fed sheet of a media enters from the import of the pump housing, and the cam follower of process rotation takes the outlet of the pump housing to and exports from this outlet.
The rotor of the cammingly birotor pump of prior art comprises rotor body that is provided with central shaft hole and the multi-disc blade that is located on the rotor body periphery, present big multiple-blade is solid, just there is following shortcoming in this: 1, Heavy Weight, thus make the power of supporting motor bigger, not energy-conservation; 2, the raw material of rotor needs is many, the cost height; 3, the surface of contact of the bi-side of rotor and the pump housing is big, makes friction factor bigger like this, makes damping big; 4, in course of conveying, the impurity in the fed sheet of a media may scratch the pump housing, pump cover or rotor etc. as hard thing such as iron filings, rubble, glass slag.
Also have at present on the bi-side of the rotor of birotor pump and set up cavity, also be appreciated that and establish a dividing plate in the centre of through hole, though this structure is in light weight, conservation, friction factor are little, avoid scratching the pump housing, pump cover or rotor, but when the cammingly birotor pump uses at food, pharmaceutical industry, the groove of rotor cleans inconvenience like this, and cleaning is unclean, and residual like this medium can go bad, directly influence is used, and also is to use scope little.
Summary of the invention:
The technical problem to be solved in the present invention, provide a kind of in light weight, conservation, friction factor little, avoid scratching the pump housing, pump cover or rotor and clean convenient, the rotor of birotor pump completely.
Technical solution of the present invention is, the rotor of the cammingly birotor pump of following structure is provided, and comprises the rotor body that is provided with central shaft hole, and the periphery of described rotor body is provided with the multi-disc blade, and each blade is provided with through hole or the sealed cavity that parallels to the axis.
Each blade is provided with axial hole, the axis of described through hole and the parallel axes of central shaft hole.
Each blade is provided with the axial seal cavity, the axis of described sealed cavity and the parallel axes of central shaft hole.
Described sealed cavity is meant that described each blade is provided with through hole, and described through hole two ends all are fixed with the cover plate of sealing through hole.
A wherein end of described through hole is provided with cover plate.
The outerplanar of every cover plate flushes with the side of blade.
The ratio of the cross section of described through hole or sealed cavity and the cross-section area of blade is 0.55～0.7: 1.
The ratio of the cross section of described through hole or sealed cavity and the cross-section area of blade was at 0.6: 1.
Adopt after the above structure compared with prior art, the present invention has the following advantages: 1, in light weight, thus reduce the power of supporting motor, energy-conservation; 2, reduce the raw material that casting needs, cost is low; 3, reduce the bi-side of rotor and the surface of contact of the pump housing, make friction factor little like this, make damping little; 4, in course of conveying, if use in industries such as chemical industry, promptly fed sheet of a media undergoes no deterioration, and can establish through hole like this on rotor, and hard thing impurity such as iron filings, rubble, glass slag can enter in the through hole like this, avoids scratching the pump housing, pump cover or rotor etc.; If use in industries such as food, pharmacy, promptly fed sheet of a media can go bad, and is provided with sealed cavity like this on rotor, avoids fed sheet of a media to enter in the cavity, and it is convenient and thorough to clean simultaneously, guarantees that birotor pump normally uses, and using scope is wide like this.
As improvement, each blade is provided with axial hole, and the axis of described through hole and the parallel axes of central shaft hole are used in the not perishable industry of fed sheet of a media like this, and in light weight, conservation, friction factor be little, avoid scratching the pump housing, pump cover or rotor.
As improvement, each blade is provided with the axial seal cavity, and the axis of described sealed cavity and the parallel axes of central shaft hole are used in the perishable industry of fed sheet of a media like this, and it is convenient to clean.
As improvement, described sealed cavity is meant that described each blade is provided with through hole, and described through hole two ends all are fixed with the cover plate of sealing through hole, convenient like this processing through hole, and can prevent that fed sheet of a media from entering in the through hole after the sealing.
As improvement, the ratio of the cross section of described through hole or sealed cavity and the cross-section area of blade is 0.55～0.7: 1, and make rotor not only in light weight but also enough intensity arranged like this.
