Abstract
The utility model relates to a vacuum pump rotor which comprises a rotating shaft and a body. Blades are arranged on the body, the part, connected with the rotating shaft, of the body is the bottom of the body, the part, away from the rotating shaft, of the body is the top of the body, a middle part is arranged between the top and the bottom, the first blade is arranged on the bottom, the second blade is arranged on the top, the third blade is arranged on the middle part of the body, the second blade is longer than the first blade, and the third blade is longer than the second blade. According to the vacuum pump rotor, a vacuum pump can be protected during high-speed operation, the rotation of the vacuum pump cannot be influenced due to flying-in debris, normal work of the vacuum pump is guaranteed, and energy consumption of the vacuum pump during operation can be reduced.
Description
Technical field
The utility model relates to a kind of vacuum pump rotor.
Background technique
Vacuum pump is applied to manufacturing the environment of vacuum, its mode of action is at a suction port, air to be inputted, and utilize inner helical rotor the low-pressure gas of this suction port to be compressed to the relief opening of high voltage terminal, to produce the state of vacuum, therefore quality and the rotor of vacuum manufacturing effect have close relationship, therefore rotor is also referred to as the heart of vacuum pump, except affecting the usefulness of vacuum pump, also can affect its working life and cost.But in the process running up at vacuum pump; often there will be product gas leakage or product breakage to make vacuum pump be subject to powerful gas shock; if having product chip to enter vacuum pump can cause damage to blade; simultaneously countershaft and rotor subject be connected and rotating shaft affected with being connected of power system; make vacuum pump unstable in running up; shorten the working life of vacuum pump, improved cost.
Summary of the invention
The purpose of this utility model is to provide a kind of and protects vacuum pump normally to use and the vacuum pump rotor reducing costs that increases the service life.
To achieve these goals, the utility model adopts following technological scheme: a kind of vacuum pump rotor, comprise rotating shaft and main body, in described main body, be provided with blade, the part that described main body is connected with rotating shaft is its bottom, be its top away from the part of rotating shaft, it between top and bottom, is its middle part, on described bottom, be provided with the first blade, on described top, be provided with the second blade, main body is provided with the 3rd blade on middle part, and the second length of blade is longer than the length of the first blade, and the 3rd length of blade is longer than the length of the second blade.
Further, the middle part of described main body is provided with cavity, and described cavity is coaxial with rotating shaft.
Further, the radius of the radius ratio rear end of described cavity front end is little.
Further, described rotor subject and blade are one-body molded.
Further, described blade is set to eleventh floor.
Further, the joint of three layers of blade of described front end and rotor subject is respectively equipped with bulge loop.
The utility model compared with prior art, there is following beneficial effect: 1, the length of blade of bottom part body is shorter than the length of blade at top, when vacuum pump is in the time running up, not only can reduce energy consumption, and be conducive to bottom protection and the blade at middle part, can be because of product not leaking air or be subject to the shock of chip, the working life of protection vacuum pump when damaged; 2, at main body middle part, cavity is set, can plays the effect of further protection blade, the chip forming while making gas leakage or breakage enters cavity, and can not go impact blades; 3, rotor subject and blade are one-body molded, improve the quality of rotor, ensure working life.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model vacuum pump rotor.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of vacuum pump rotor of the utility model, comprise rotating shaft 1 and main body 2, in described main body 2, be provided with eleventh floor blade 3, the part that described main body 2 is connected with rotating shaft 1 is its bottom, be its top away from the part of rotating shaft 1, it between top and bottom, is its middle part, on described bottom, be provided with two-layer the first blade 31, on described top, be provided with two-layer the second blade 32, main body is provided with seven layer of the 3rd blade 33 on middle part, the length of second blade 32 Length Ratio the first blades 31 is long, the length of the 3rd blade 33 Length Ratio the second blades 32 is long, described main body 2 is one-body molded with blade 3, three layers of blade 3 of described main body 2 front ends are respectively equipped with bulge loop 4 with the joint of main body 1.
The middle part of described main body 2 is provided with cavity 5, and described cavity 5 is coaxial with rotating shaft 1, and the radius of the radius ratio rear end of described cavity 5 front ends is little.
By the blade 3 of different length being set and at main body 2 middle parts, cavity 5 being set; can form protective action to the blade of the vacuum pump in running up 3; in the working life that not only can extend vacuum pump, reduce costs, and its volume can reduce the vacuum pump energy consumption in when running.
