Abstract
The utility model discloses a kind of anticorrosion dry screw vacuum pump rotor, it comprises the rotating shaft and helical blade of being made up of stainless steel, titanium alloy or Hastelloy, and described helical blade to be wrapped in rotating shaft and to be integral type structure with rotating shaft; Described helical blade is provided with equalizing orifice.Advantage is: the utility model adopts stainless steel, titanium alloy or Hastelloy material to make, and it can allow rotating shaft and helical blade have preferably anti-corrosive properties, effectively improves the rigid of rotating shaft and helical blade, extends its working life.
Description
Technical field
The utility model belongs to the rotor technology field on screw rod vacuum pump, especially relates to a kind of anticorrosion dry screw vacuum pump rotor.
Background technique
At present, screw vacuum pump rotor on market all adopts cast iron or general Cast Steel to manufacture, its antiseptic property of rotor that this employing cast iron or cast steel are made is poor, is in use easily subject to extraneous corrosion and affects the rigid of rotor, making the working life of rotor not high; Therefore be necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, and provide a kind of anticorrosion dry screw vacuum pump rotor, it has the advantages that antiseptic property is good, rigid is high and can increase the service life.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of anticorrosion dry screw vacuum pump rotor, it comprises the rotating shaft and helical blade of being made up of stainless steel, titanium alloy or Hastelloy, and described helical blade to be wrapped in rotating shaft and to be integral type structure with rotating shaft; Described helical blade is provided with equalizing orifice.
Further, the stainless steel making described rotating shaft and helical blade is the one in 304 stainless steels or 316L stainless steel or two phase stainless steel.
Further, the titanium alloy material making described rotating shaft and helical blade is the one in TA titanium alloy or TB titanium alloy or TC titanium alloy.
Further, the Hastelloy material making described rotating shaft and helical blade is the one in B2 Hastelloy or B3 Hastelloy or C-276 Hastelloy.
After adopting said structure, the utility model is compared to the prior art advantageously: the utility model adopts stainless steel, titanium alloy or Hastelloy material to make, it can allow rotating shaft and helical blade have preferably anti-corrosive properties, the rigid of effective raising rotating shaft and helical blade, extends its working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment 1, as shown in Figure 1: a kind of anticorrosion dry screw vacuum pump rotor, comprises the rotating shaft 10 and helical blade 20 of being made up of stainless steel, and stainless steel selects the one in 304 stainless steels or 316L stainless steel or two phase stainless steel; Helical blade 20 to be wrapped in rotating shaft 10 and to be integral type structure with rotating shaft, its canoe can be selected according to the actual needs to be left-handed or dextrorotation in use; Helical blade 20 is provided with equalizing orifice 21.Adopt stainless steel material mass-energy to allow rotating shaft and helical blade have preferably anti-corrosive properties, effectively improve the rigid of rotating shaft and helical blade, extend its working life.
Embodiment 2, and the structure of embodiment 2 is roughly the same with embodiment 1, and its difference is: the material making rotating shaft 10 and helical blade 20 adopts titanium alloy, and described titanium alloy can select the one in TA titanium alloy or TB titanium alloy or TC titanium alloy; It can reach the effect in embodiment 1 equally.
Embodiment 3, the structure of embodiment 3 is roughly the same with embodiment 1, its difference is: the material making rotating shaft 10 and helical blade 20 adopts Hastelloy, and described Hastelloy can select the one in B2 Hastelloy or B3 Hastelloy or C-276 Hastelloy; It can reach the effect in embodiment 1 equally.
