Abstract
The invention discloses a novel double-screw vacuum pump which comprises a handle, a pump body and a bottom plate. The pump body is arranged on the bottom plate and is internally provided with a cooling water jacket and a pump cavity. The periphery of the pump cavity is wrapped by the cooling water jacket. A water inlet is formed in the lower end of the left side of the cooling water jacket. A water outlet is formed in the upper end of the right side of the cooling water jacket. An opening water groove is formed in the top of the cooling water jacket. The water outlet is connected with the left end of the water groove through a pipeline, and the water inlet is connected with the right end of the water groove through a pipeline. An air suction port is formed in the left side of the pump cavity, an exhaust port is formed in the right side of the pump cavity, and the air suction port and the exhaust port penetrate the cooling water jacket to be connected with the atmosphere. Two different double-end claw type screw rotors which are opposite in rotating direction are arranged in the pump cavity. A permanent magnet shield motor is arranged at the top of the pump cavity. The rotors are connected with the permanent magnet shield motor in a connecting sleeve expanding manner, feeding and discharging of water are achieved by means of the elevation difference, energy consumption is reduced, and heat dissipation is enhanced.
