A rotary vacuum pump using vacuum oil is provided. A cooling water jacket is formed in parts of a pump module to make a cooling water circulation structure herein, thereby preventing an increase in the temperature of the pump module by directly cooling heat generated from the pump module. And, oil is cooled in a vacuum oil contact surface coming in contact with the cooling water jacket of the pump module, and the oil transferred by an oil pump flows to an oil path exposed to the cooling water jacket to cool the oil by the cooling water stored in the cooling water jacket, thereby preventing an increase in the temperature of the pump module. Therefore, the present invention provides stable pump environment through a structure of cooling oil threefold. Moreover, the present invention reduces the number of parts by making a pump body and a single-stage cylinder in a single part, thereby reducing production costs.
Description
technical field [0001] The present invention relates to a vacuum pump, and more particularly, to a rotary vacuum pump that uses vacuum oil to ensure the vacuum of a pump device. Background technique [0002] Generally speaking, a vacuum device is a device for eliminating gas molecules in a sealed container, which is configured to suck and compress at a low pressure below atmospheric pressure, and discharge the compressed gas into the air, thereby increasing the degree of vacuum in the container. Such vacuum pumps can be divided into mechanical vacuum pumps and diffusion pumps, which are designed as dry and wet, respectively. A diffusion pump is a wet type that uses oil to secure a high vacuum, and a mechanical vacuum pump is a dry type that does not use oil and can secure a relatively low vacuum, but a mechanical vacuum pump has a simple structure and high durability, And it has a stable vacuum degree, so the mechanical vacuum pump is widely used in various industrial field...
