Problems solved by technology
At present, the rotary vane vacuum pumps on the market generally adopt an oil-sealed mechanical structure. When the vacuum pump is running, the continuous contact and friction between the rotary vane and the inner cavity of the pump head will generate a lot of heat. If the temperature of the pump head is too high, the vacuum degree of the vacuum pump will easily decrease. Among them The purity of the sucked air at the inlet will affect the service life of the vacuum pump

The invention provides an oil seal type mechanical vacuum pump head and belongs to the technical field of mechanical vacuum equipment. The oil seal type mechanical vacuum pump head solves the problemthat the heat dissipation effect of an existing vacuum pump is poor. The oil seal type mechanical vacuum pump head comprises a shell, a rotor, rotating pieces and an air inlet device. A vacuum pump stator inner cavity of an integrated structure is arranged in the shell, and multiple sliding grooves are evenly formed in the rotor in the circumferential direction. Each sliding groove is internally provided with the corresponding rotating piece in a sliding manner. A limiting groove is formed in each rotating piece. Multiple first heat dissipation teeth transversely arranged and multiple second heat dissipation teeth longitudinally arranged are arranged on the outer side of the shell. The air inlet device is installed on the top of the shell through a hexagon nut and communicates with an inner cavity of the shell. A shock absorption rubber pad is installed at the bottom of the shell through a screw rod. The oil seal type mechanical vacuum pump head has the beneficial effects that the heatdissipation effect is good, and the service life is longer.
Description
technical field [0001] The invention belongs to the technical field of mechanical vacuum equipment, and relates to a vacuum pump, in particular to an oil-sealed mechanical vacuum pump pump head. Background technique [0002] A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to pump air into a pumped container to obtain a vacuum. Generally speaking, a vacuum pump uses various methods to improve, generate and maintain a vacuum in a closed space. Vacuum device. The function of the vacuum pump is to extract gas molecules from the vacuum chamber, reduce the gas pressure in the vacuum chamber, and make it reach the required vacuum degree. At present, the rotary vane vacuum pumps on the market generally adopt an oil-sealed mechanical structure. When the vacuum pump is running, the continuous contact and friction between the rotary vane and the inner cavity of the pump head will generate a lot of heat. If the temperature ...
