In summary, in the automatic sealing failure alarm device for the screw vacuum pump, the telescopic column 202 is started by the first motor, at this time, the telescopic column 202 contracts to expose the pump body 107, and along with the retraction of the telescopic column 202, the screw rod in the rotating member 203 starts to ascend along with the retraction position of the telescopic column 202, because the gear in the rotating member 203 is internally provided with a threaded hole with a size matched with that of the screw rod, the gear starts to rotate along with the ascent of the screw rod, because the gear included in the rotating member 203 is meshed with the rack 204, the rotation of the gear drives the rack 204 to start moving, the corresponding driven block 205 meshed with the rack 204 starts to rotate, and because the driven block 205 is fixedly connected with the filter disc 206, the rotation of the driven block 205 causes the filter disc 206 to rotate out of the original position by taking the driven block 205 as the rotation center, so as to rotate the filter disc 206 out of the liquid inlet 207, thereby cleaning the filter disc 206 and achieving the purposes of filtering impurities with larger external volume and cleaning the filter elements.
The automatic alarm device for the sealing failure of the screw vacuum pump starts the telescopic column 202 through the first motor, at the moment, the telescopic column 202 contracts to expose the pump body 107, at the moment, a worker starts the second motor, the second motor starts the telescopic rod 105, at the moment, the telescopic rod 105 contracts, as one end of the telescopic rod 105 is fixedly connected with the limiting block 106, a through hole with the size matched with that of the pump body 107 is formed in the limiting block 106, the pump body 107 can be close to the direction of the annular block 103 along with the movement of the telescopic rod 105 until being meshed with the annular block 103, at the moment, the pump body 107 starts to rotate, as the wedge block with the size matched with the outer surface of the pump body 107 is arranged in the annular block 103, when the pump body 107 starts to rotate, the wedge block on the inner side of the annular block 103 can rub against the surface of the pump body 107, so as to clean the substances which are not easy to clean the surface of the pump body 107, the purpose of cleaning impurities which are not easy to clean in the vacuum pump is achieved.
