Abstract
The invention relates to gas conveying equipment. The gas conveying equipment comprises a machine shell, a motor and machine vanes. The motor is arranged at the rear end of the machine shell, and the machine vanes are arranged in the machine shell and connected with a transmission shaft of the motor. The machine vanes comprise a front cover, a rear cover and machine vane bodies. The multiple machine vane bodies are annularly arrayed between the front cover and the rear cover. The machine vane bodies are vertically arranged between the front cover and the rear cover. The machine vane bodies are each in an arc shape. Extension lines connecting the outer centers and the inner centers of the machine vane bodies pass through the circle centers of the front cover and the rear cover. According to the gas conveying equipment, losses of conveyed gas are small, the abrasion and breakage conditions of the machine vanes are fewer, and the gas conveying equipment is durable and high in efficiency.
Description
Technical field
The present invention relates to a kind of machinery, particularly relate to a kind of gas transportation facilities.
Background technique
Gas transportation facilities is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, 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, thus reaches the object of dispatch gas.The machine leaf of machine leaf was arranged between protecgulum and bonnet in the past, certain deviation is had relative to the center of circle of front/rear cover between its machine leaf, can make like this in the process of gas transportation facilities dispatch gas, except producing except the airflow direction of dispatch as requested, also can produce the air-flow of bias direction, cause gas transportation facilities dispatch loss; Although the deviation flow produced is less simultaneously; but be that it improves the probability that resultant turbulence or eddy current situation can be caused to occur when being subject to external disturbance; 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 time serious; add the time of gas transportation facilities shutdown maintenance, and then reduce the efficiency of supply of gas transportation facilities.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and carry that air-loss is little, machine leaf wear and rupture situation the is few durable in use and gas transportation facilities that efficiency is high.
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 shows multi-disc machine leaf, and described machine leaf is vertically arranged between protecgulum and bonnet; Described machine leaf is arc; The elongation line that the outer side center of described machine leaf is connected with medial center is by the center of circle of protecgulum and bonnet.Described machine leaf and protecgulum, bonnet are welded to connect; Motor carrier is provided with below described motor.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention is vertically arranged between protecgulum and bonnet due to machine leaf, machine leaf is curved, the elongation line that the outer side center of machine leaf is connected with medial center is by the center of circle of protecgulum and bonnet, in the process of gas transportation facilities dispatch gas, the air-flow of bias direction can not be produced, avoid gas transportation facilities dispatch loss, also reduce the probability causing resultant turbulence or eddy current situation to occur when being subject to external disturbance simultaneously, the machine leaf of machine leaf is avoided to occur fatigue crack, or there is the resonance phenomenon of machine leaf, more avoid the phenomenon of the machine leaf fracture of machine leaf, reduce the time of gas transportation facilities shutdown maintenance, and then add the efficiency of supply of gas transportation facilities.
Accompanying drawing explanation
Figure l 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: l, 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 figure l to Fig. 2, a kind of gas transportation facilities, comprise casing l, motor 2 and machine leaf, described casing l rear end is provided with motor 2, is provided with motor carrier 3 below described motor 2, and described machine leaf is arranged in casing l, 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 shows 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 medial center is by the center of circle of protecgulum 5 and bonnet 6.
During use, the transmission shaft 4 of motor 2 is with motivation leaf to rotate, thus reaches the object of dispatch gas.In the process of dispatch gas; the air-flow of bias direction can not be produced; avoid gas transportation facilities dispatch loss; also reduce the probability causing resultant turbulence or eddy current situation to occur when being 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, the phenomenon that the machine leaf 7 more avoiding machine leaf ruptures; reduce the time of gas transportation facilities shutdown maintenance, and then add the efficiency of supply of gas transportation facilities.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in right of the present invention the change of the above embodiment, modification.
