the telescopic column 202 is started through the first motor, the telescopic column 202 contracts at the moment, the telescopic column 202 contracts to expose the pump body 107, the second motor is started by a worker at the moment, the telescopic rod 105 is started by the second motor, the telescopic rod 105 contracts at the moment, because one end of the telescopic rod 105 is fixedly connected with the limiting block 106, a through hole matched with the pump body 107 in size 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 the telescopic rod is meshed with the annular block 103, the pump body 107 starts to rotate at the moment, because the annular block 103 is internally provided with a wedge matched with the outer surface of the pump body 107 in size, when the pump body 107 starts to rotate, the wedge inside the annular block 103 can rub against the surface of the pump body 107, and therefore substances which are not easy to clean the surface of the pump body 107 are cleaned.
The external condition of the screw vacuum pump is sensed through the sensor 301, when the screw vacuum pump is sealed to fail, the sensor 301 sends a signal to start the alarm 302, and therefore people are informed of the failure of the screw vacuum pump.
In summary, in the automatic sealing failure alarm device of the screw vacuum pump, the telescopic column 202 is started by the first motor, the telescopic column 202 contracts at this time, the telescopic column 202 contracts to expose the pump body 107, and the screw rod in the rotating member 203 starts to ascend along with the retracting position of the telescopic column 202 at this time, 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 ascending of the screw rod, because the gear contained 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 can make the filter disc 206 rotate out of the original position by taking the driven block 205 as a rotation center, and the filter disc 206 is rotated out from the liquid inlet 207, so that the filter disc 206 can be cleaned, and the purposes of filtering impurities with a large external volume and cleaning the filter elements are achieved.
This screw vacuum pump's sealed failure autoalarm, the post 202 that will stretch out and draw back through first motor starts, the post 202 that stretches out and draws back this moment, the post 202 that stretches out and draws back contracts makes the pump body 107 expose, the staff starts the second motor this moment, the second motor can start telescopic link 105, telescopic link 105 can contract this moment, because telescopic link 105 one end and limiting block 106 fixed connection, limiting block 106 is inside to be seted up the through-hole of size and pump body 107 assorted, can make the pump body 107 be close to the direction of ring block 103 along with the motion of telescopic link 105, until with the meshing of ring block 103, make the pump body 107 begin to rotate this moment, because inside being provided with size and the pump body 107 surface assorted voussoir of ring block 103, so when the pump body 107 begins to rotate, the voussoir of ring block 103 inboard can rub with the surface of the pump body 107, thereby clear up the material that the pump body 107 surface is difficult for the clearance, reach the purpose of the impurity of the inside difficult clearance of clearance vacuum pump.
