Working principle:
the first step: through the setting of collecting strip device 3, after the medium in body pipe 101 inner chamber permeates to collecting pipe 201 inside, through the existence of screw rod 104, can drive inner tube device 5 and rotate, thereby can take place the contact with collecting strip device 3 when inner tube device 5 rotates owing to the special form of inner tube cover 502, when inner tube cover 502 rotates like this, inner tube cover 502 can promote the embedded post 304, thereby make collecting strip 301 take place the upset, make the indent end of collecting strip 301 contact with the outside surface of inner tube cover 502, the medium that the indent end can collect collecting pipe 201 inboard and inner tube cover 502 outside leakage like this, collect in the inner chamber of collecting pipe 201 is pressed into to the medium that will reveal in the rotatory in-process of inner tube device 5, guarantee the timely clearance of revealing the medium.
And a second step of: the collecting sponge of adaptation is put into the inside of collecting pipe 201 from the last port of placing the mouth 210 along the right side of placing ring 401 before the use, through the shape design of placing ring 401 lower extreme, thereby make collecting sponge place along placing ring 401 and collecting pipe 201's inner chamber lateral wall laminating, and through the shape design of placing ring 401, make the collecting sponge of end can be natural wear out from placing ring 401 upper end right side, through the design of placing ring 401, will collect the sponge and impress on collecting pipe 201 inner chamber lateral wall, moreover can be very convenient will collect the sponge and take, the operation is very simple and convenient.
And a third step of: through putting into the collection sponge in the inner chamber of collecting pipe 201 and carrying out the collection of medium, can be convenient for in the inner chamber of collecting pipe 201 clear up the medium like this, protected the inner chamber lateral wall of collecting pipe 201 simultaneously, effectually avoided the injury of medium to the lateral wall of collecting pipe 201 inner chamber, great improvement collecting pipe 201's life.
Fourth step: through the design of interior pipe box 502 for the leakage path of medium in the body pipe 101 changes to the center mouth of front bezel 212 along the outside edge backward infiltration of interior pipe box 502, through the petal wave-like design of interior pipe box 502, makes the leakage path of medium become rugged and the journey becomes long, makes the leakage of medium can be more difficult, thereby effectually avoided the position that the medium got into gear 603 of rear side place, reduced the risk that causes the emulsion of lubricating liquid.
Fifth step: through timely change collection sponge, medium that can be timely to collection pipe 201 inside is collected is cleared up, and the clearance in-process need not dismantle the screw vacuum pump to guarantee can not stagnate because the saturation problem of collection pipe 201 cavity at the operation in-process of screw vacuum pump, guaranteed the normal operating of device clearance.
Sixth step: through the rotation of interior pipe box 502 to make collection strip device 3 reverse and reset under the effect of spring 303, when collection strip 301 overturns, the indent end of collection strip 301 can be automatic collect the medium that will reveal to collect in the pipe 201, in the inner chamber that transports to collect pipe 201, through the extrusion of interior pipe box 502 and collection strip device 3, thereby accomplish the automatic collection of medium, great increase the automatic performance of device.
Seventh step: through the gomphosis of interior pipe box 502 special shape and the special shape of embedded post 304, in the whole in-process of interior pipe box 502 pivoted, in-process of the contact of interior pipe box 502 and embedded post 304, accomplish the collection to leaking the medium, accomplish the dynamic closure to collecting pipe 201 in the position that interior pipe box 502 and embedded post 304 stagger in addition to guarantee the compactness that body pipe 101 and main part device 6 are connected.
Eighth step: through the design of collection tube assembly 2, in the design of front plate 212, inner shroud 502 and collection tube cap 205 surface, the leakage path of medium has been greatly prolonged, and collection tube cap 205 surface design's shrouding 207 has effectually plugged the path that inner shroud 502 surface reached collection tube cap 205 rear side, guarantees that the medium can not enter into the rear side of main body plate 601 to guarantee the anticorrosive of device.
Ninth step: by the design of the rear groove 203, the main body bearing 204 is placed inside the rear groove 203, and by such 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, thereby effectively protecting the main body bearing 204.
Tenth step: through installing the anticorrosive coating on the inside wall of go-between 209 for the problem that leads to the fact the dislocation owing to frequent twisting can not appear in the both sides of anticorrosive coating, thereby avoided anticorrosive coating by the problem of tearing when the operation when guaranteeing the normal work of screw vacuum pump and guaranteeing the anticorrosive effect, prolonged the anticorrosive effective period of device.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
