Abstract
The invention discloses gas transportation equipment. The gas transportation equipment comprises a case, a motor and a blade, wherein the motor is arranged at the back end of the case; the blade is arranged in the case and connected with a transmission shaft of the motor, the blade comprises a front cover, a back cover and a plurality of arc-shaped blade bodies, the plurality of blade bodies are annularly arrayed and vertically arranged between the front cover and the back cover; and an extension line connecting an inner side center with an inner side center of each blade body passes through centers of the front and back covers. According to the gas transportation equipment, the loss of transported gases is small, wear and breakage conditions of the blades are less, and the gas transportation equipment is durable in use and high in efficiency.
Description
Technical field
The present invention relates to a kind of machinery, relate in particular to a kind of gas transportation facilities.
Background technique
Gas transportation facilities is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Gas transportation facilities generally comprises casing, motor and machine leaf, and casing rear end is provided with motor, and machine leaf is arranged in casing, is connected with the transmission shaft of motor, and during running, the transmission shaft band motivation leaf of motor rotates, thereby reaches the object of dispatch gas.The machine leaf of machine leaf was arranged between protecgulum and bonnet in the past, the center of circle with respect to front/rear cover between its machine leaf has certain deviation, can make like this in the process of gas transportation facilities dispatch gas, except producing as requested the airflow direction of dispatch, also can produce the air-flow of bias direction, cause gas transportation facilities dispatch loss; Although the deviation flow producing less simultaneously; but having improved in the situation that is subject to external disturbance, it can cause the probability that gas disorder or eddy current situation occur; easily there is fatigue crack in the machine leaf of equipment; or there is the resonance phenomenon of machine leaf; the phenomenon of meeting generator leaf fracture when serious; increase the time of gas transportation facilities shutdown maintenance, and then reduced the efficiency of supply of gas transportation facilities.
Summary of the invention
Technical problem to be solved by this invention is: a kind of carry that air-loss is little, machine leaf wear and rupture situation is few durable in use and gas transportation facilities that efficiency is high are provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of gas transportation facilities comprises casing, motor and machine leaf, described casing rear end is provided with motor, described machine leaf is arranged in casing, be connected with the transmission shaft of motor, described machine leaf comprises protecgulum, bonnet and machine leaf, between described protecgulum and bonnet, circular array is shown multi-disc machine leaf, and described machine leaf is vertically arranged between protecgulum and bonnet; Described machine leaf is curved; The elongation line that the outer side center of described machine leaf is connected with center, inner side is by the center of circle of protecgulum and bonnet.
Described machine leaf and protecgulum, bonnet are welded to connect.
Described motor below is provided with motor carrier.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention is because machine leaf is vertically arranged between protecgulum and bonnet, machine leaf is curved, the elongation line that the outer side center of machine leaf is connected with center, inner side is by the center of circle of protecgulum and bonnet, in the process of gas transportation facilities dispatch gas, can not produce the air-flow of bias direction, avoided gas transportation facilities dispatch loss, also reduced the probability that causes gas disorder or the generation of eddy current situation in the situation that is subject to external disturbance simultaneously, avoid the machine leaf of machine leaf to occur fatigue crack, or the resonance phenomenon that occurs machine leaf, more avoided the phenomenon of the machine leaf fracture of machine leaf, reduced the time of gas transportation facilities shutdown maintenance, and then increased the efficiency of supply of gas transportation facilities.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of a kind of gas transportation facilities of the present invention;
Fig. 2 is the sectional view of a kind of gas transportation facilities of the present invention;
In figure, be labeled as: 1, casing; 2, motor; 3, motor carrier; 4, transmission shaft; 5, protecgulum; 6, bonnet; 7, machine leaf.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Refer to Fig. 1 to Fig. 2, a kind of gas transportation facilities, comprise casing 1, motor 2 and machine leaf, described casing 1 rear end is provided with motor 2, and described motor 2 belows are provided with motor carrier 3, and described machine leaf is arranged in casing 1, be connected with the transmission shaft 4 of motor 2, described machine leaf comprises protecgulum 5, bonnet 6 and machine leaf 7, and between described protecgulum 5 and bonnet 6, circular array is shown multi-disc machine leaf 7, and described machine leaf 7 is vertically arranged between protecgulum 5 and bonnet 6; Described machine leaf 7 is welded to connect with protecgulum 5, bonnet 6; Described machine leaf 7 is curved; The elongation line that the outer side center of described machine leaf 7 is connected with center, inner side is by the center of circle of protecgulum 5 and bonnet 6.
During use, the transmission shaft 4 band motivation leaves of motor 2 rotate, thereby reach the object of dispatch gas.In the process of dispatch gas; can not produce the air-flow of bias direction; avoided gas transportation facilities dispatch loss; also reduced the probability that causes gas disorder or the generation of eddy current situation in the situation that is subject to external disturbance simultaneously; avoid the machine leaf 7 of machine leaf to occur fatigue crack, or occur the resonance phenomenon of machine leaf 7, more avoided the phenomenon of machine leaf 7 fractures of machine leaf; reduce the time of gas transportation facilities shutdown maintenance, and then increased the efficiency of supply of gas transportation facilities.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the above embodiment's variation, modification, all will drop within the scope of claim of the present invention.
