| description | The utility model relates to the technical field of vacuum pumps, in particular to a high-stability variable-frequency screw vacuum pump. A high-stability variable-frequency screw vacuum pump comprises a protective shell, a screw vacuum all-in-one machine is arranged in the protective shell, a supporting frame is installed below the screw vacuum all-in-one machine, a shock pad is fixed to the lower portion of the supporting frame, an air inlet valve is arranged on the screw vacuum all-in-one machine, and an oil spraying hole is formed in the screw vacuum all-in-one machine. The screw vacuum all-in-one machine is provided with an electromagnetic valve and connected with a one-way valve. The electromagnetic valve on the screw vacuum all-in-one machine is used for accurately controlling the valve of the flow dividing block and the valve of the vacuum air inlet valve, and the electromagnetic valve controls the air inlet amount of the screw vacuum all-in-one machine in the operation process, so that the stop valve |
