The working principle is as follows:
the first step is as follows: through the setting of collecting strip device 3, the medium infiltration in body pipe 101 inner chamber receives the inside back of header 201, through the existence of screw rod 104, can drive inner tube device 5 and rotate, thereby because the special form of inner tube cover 502 can take place the contact with collecting strip device 3 when inner tube device 5 rotates, pipe cover 502 rotates including like this, inner tube cover 502 can promote the embedded column 304, thereby make collection strip 301 take place the upset, make the indent end of collecting strip 301 and the outside surface contact of inner tube cover 502, the indent end can be collected the medium of revealing in the collecting pipe 201 inboard and the inner tube cover 502 outside like this, the medium that will reveal in the rotatory in-process of inner tube device 5 is impressed and is collected in the inner chamber of header 201, guarantee the timely clearance of revealing the medium.
The second step is that: put into the inside of collecting pipe 201 along the upper port of placing mouth 210 on the right side of placing ring 401 with the collection sponge of adaptation before using, shape design through placing ring 401 lower extreme, thereby make the collection sponge place along the laminating of the inner chamber lateral wall of placing ring 401 and collecting pipe 201, and through the shape design of placing ring 401, make the collection sponge of end wear out from placing ring 401 upper end right side naturally, through the design of placing ring 401, the collection sponge is impressed on the lateral wall of collecting pipe 201 inner chamber, and can be very convenient will collect the sponge and take, the operation is very simple and convenient.
The third step: put into the collection sponge through the inner chamber at collecting pipe 201 and carry out the collection of medium, can be convenient for clear up the medium in collecting pipe 201's inner chamber like this, protected collecting pipe 201's inner chamber lateral wall simultaneously, the effectual injury of avoiding the medium to collecting pipe 201 inner chamber's lateral wall, great improvement collecting pipe 201's life.
The fourth step: through the design of the inner sleeve 502, the leakage path of the medium in the body tube 101 is changed to permeate backwards from the central opening of the front plate 212 along the outer edge of the inner sleeve 502, and through the petal wave-shaped design of the inner sleeve 502, the leakage path of the medium is rugged, the path is lengthened, the leakage of the medium is more difficult, the medium is effectively prevented from entering the position of the gear 603 on the rear side, and the risk of emulsifying the lubricating liquid is reduced.
The fifth step: collect the sponge through timely change, can be timely clear up the inside medium of collecting pipe 201, and the clearance in-process need not dismantle the screw vacuum pump to guarantee can not be because the saturation problem of collecting pipe 201 cavity and the stagnation in the operation of screw vacuum pump, guaranteed the normal operating of device clearance.
And a sixth step: through the rotation of inner pipe sleeve 502 to make collection strip device 3 under the effect of spring 303, reverse and reset, when collection strip 301 overturns, the indent end of collection strip 301 can be automatic will reveal to collect the medium in collection pipe 201, in the inner chamber of transporting collection pipe 201, through inner pipe sleeve 502 and collection strip device 3's extrusion, thereby accomplish the automatic collection of medium, great increase the automatic performance of device.
The seventh step: by the embedding of the special shape of the inner pipe sleeve 502 and the special shape of the embedded column 304, the collection of the leakage medium is completed in the whole process of the rotation of the inner pipe sleeve 502 and the contact process of the inner pipe sleeve 502 and the embedded column 304, and in addition, the dynamic sealing of the collection pipe 201 is completed at the staggered position of the inner pipe sleeve 502 and the embedded column 304, so that the connection tightness of the body pipe 101 and the main body device 6 is ensured.
Eighth step: through the design of collecting pipe device 2, in the design on front plate 212, inner tube cover 502 and collection tube cover 205 surface, the great extension of the leakage route of medium, and the shrouding 207 of the surface design of collection tube cover 205 has effectually blocked the route that inner tube cover 502 surface reachd the collection tube cover 205 rear side, guarantees that the medium can not enter into the rear side of main part board 601 to the anticorrosive of device has been guaranteed.
The ninth step: through the design of the rear groove 203, the main body bearing 204 is placed inside the rear groove 203, and through the design, the main body bearing 204 is not directly contacted with the collecting pipe 201, so that the main body bearing 204 is not exposed in the space of the medium, and the main body bearing 204 is effectively protected.
The tenth step: through installing the anticorrosive coating on the inside wall of go-between 209 for the problem because frequent wrench movement causes the dislocation can not appear in the both sides of anticorrosive coating, thereby avoided the anticorrosive coating by torn problem when the function when guaranteeing screw vacuum pump normal work and guaranteeing anticorrosive effect, prolonged the anticorrosive deadline of device.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
