Description
Technical field:
the invention relates to a sealing and cooling structure of an overspeed table.
The background technology is as follows:
the existing overspeed table adopts a structure with a zigzag sealing structure of a shaft peak, the sealing effect is not good, the offline sealing effect cannot be achieved, and the cooling measure of the overspeed table is that a cooling fan 400 is installed on a core shaft at the lower end of a rotor, a vent hole 500 is formed in the outer wall of a motor casing, the cooling fan 400 and the vent hole 500 form convection, and the cooling effect is general while working.
The invention comprises the following steps:
the present invention is directed to solving the problems of the prior art described above and providing a sealing and cooling structure for an overspeed table.
The invention adopts the technical scheme that: the utility model provides a sealing and cooling structure of overspeed table, includes protection casing, lid, motor casing, upper wiring cover, lower wiring cover, pipeline, valve and air-blower, the lid fixed connection is on the protection casing, and the protection casing is fixed connection with the upper port of motor casing, and the lower port of motor casing is fixed connection with the upper port of upper wiring cover, and the lower port of upper wiring cover is fixed connection with the upper port of lower wiring cover, and the one end of pipeline is sealed connection with the lower port of lower wiring cover, and the other end is sealed connection with the air outlet of air-blower, and the valve is connected on the pipeline;
sealing rings are adopted for sealing between the protective cover and the cover body, between the protective cover and the motor shell, between the motor shell and the upper wiring cover and between the upper wiring cover and the lower wiring cover.
Further, the upper port of the lower wire housing extends outwardly and forms a plateau-like connecting edge to which a sealing socket is connected.
The invention has the following beneficial effects:
1) The invention replaces the partial seal of the sawtooth-shaped peak at the upper end part of the original rotor with the integral seal of the main machine, and has simpler sealing mode and better sealing effect;
2) The invention can adopt the scheme of intermittent working and intermittent cooling, because the time of each overspeed test is shorter, namely the overspeed table belongs to an intermittent working mechanism, the overspeed temperature of one time is known through experiments that the stator and the rotor cannot overheat, the air blower is externally connected, the valve is closed when the host machine works, and the whole host machine is in a sealing state, so that the working requirement is met; after the test is finished, the valve and the small blower are opened to cool the whole host.
Description of the drawings:
FIG. 1 is a prior art seal and cooling configuration for an overspeed governor.
FIG. 2 is an enlarged partial view of a sealing structure of an overspeed table in the prior art.
Fig. 3 is a structural diagram of the present invention.
The specific embodiment is as follows:
the invention is further described below with reference to the accompanying drawings.
As shown in fig. 3, the invention discloses a sealing and cooling structure of an overspeed table, which comprises a protection cover 11, a cover body 12, a motor shell 13, an upper wiring cover 14, a lower wiring cover 15, a pipeline 16, a valve 17 and a blower 18, wherein the cover body 12 is fixedly connected to the protection cover 11, the protection cover 11 is fixedly connected with an upper port of the motor shell 13, a lower port of the motor shell 13 is fixedly connected with an upper port of the upper wiring cover 14, a lower port of the upper wiring cover 14 is fixedly connected with an upper port of the lower wiring cover 15, one end of the pipeline 16 is in sealing connection with a lower port of the lower wiring cover 15, the other end of the pipeline 16 is in sealing connection with an air outlet of the blower 18, and the valve 17 is connected to the pipeline 16.
Sealing rings are adopted to seal the space between the protective cover 11 and the cover body 12, the space between the protective cover 11 and the motor casing 13, the space between the motor casing 13 and the upper wiring cover 14 and the space between the upper wiring cover 14 and the lower wiring cover 15.
The upper port of the lower terminal cover 15 in the present invention extends outwardly and forms a flat connection side 151, and a sealing socket 152 is connected to the connection side 151.
According to the invention, the whole host of the overspeed table is sealed by adopting an O-shaped ring structure, and the motor wire and the sensor are correspondingly sealed by the sealing socket 152, so that the sealing effect of the host is improved.
When an overspeed test is performed, the cover body 12 is connected to the protective cover 11 in a sealing manner, so that the whole host is sealed. Because the time of each overspeed test is shorter, namely the overspeed table belongs to an intermittent working mechanism, the overspeed temperature of one time is known through experiments, the stator and the rotor cannot overheat, and an intermittent working and intermittent cooling scheme can be adopted. And an external blower 18 is connected, and the blower 18 is connected with the lower wiring cover 15 by a valve. When the host machine works, the valve is closed, and the whole host machine is in a sealing state, so that the working requirements are met. After the overspeed test is completed, the cover 12 is opened. And opening a valve and a small blower to cool the whole host.
The foregoing is merely a preferred embodiment of the invention, and it should be noted that modifications could be made by those skilled in the art without departing from the principles of the invention, which modifications would also be considered to be within the scope of the invention.
