Vacuum pump for vacuum beam welding machine

Abstract

The invention discloses a vacuum pump for a vacuum beam welding machine, and relates to the technical field of vacuum welding. The vacuum pump is used for solving the problems that a large amount of noise is frequently generated during the use period of a vacuum pump for an existing vacuum beam welding machine, the vacuum pump works in the environment for a long time, the health of the body of theuser is harmed, and the filtering effect of the vacuum pump during air suction is further enhanced. A control handle is arranged on the outer wall of a vacuum pump body, a motor is arranged on one side of the vacuum pump body, one end of the motor is provided with a coupler, one side of the control handle is provided with a demister, an exhaust pipe is arranged above the demister, a gas ballast valve is arranged on one side of the exhaust pipe, an oil filling screw plug is arranged on one side of the gas ballast valve, an oil mark is arranged on one side of the oil filling screw plug, a mooring screw plug is arranged below the oil mark, an air suction opening is formed in the vacuum pump body, an air suction valve is arranged below the air suction opening, and a rotor is arranged below the air suction valve.

Description

technical field [0001] The invention relates to the technical field of vacuum welding, in particular to a vacuum pump for a vacuum beam welding machine. Background technique [0002] Electron beam welding machine is a relatively sophisticated welding equipment that uses the principle of high-speed moving electron beam bombardment of the workpiece for welding processing. It basically represents the highest performance welding level at present. Vacuum electron beam welding uses a directional high-speed moving electron beam to hit the workpiece during the welding process to convert kinetic energy into heat energy to melt the workpiece and form a weld. The energy density of the electron beam is as high as 108 W / cm2, which can rapidly heat the weldment metal to a very high temperature, so it can melt any refractory metal and alloy. It does not require filling materials, and is generally welded in a vacuum. The weld seam is pure, smooth, and free of oxidation defects. In the pro...
