Problems solved by technology

[0004] After setting the speed increaser, the rotation speed of the screw can be increased, but it still has the following problems: the male screw and the female screw are located in the closed pump body, and the heat generated by the two is high when they work, and the closed pump body causes the heat to be insufficient. If it is released in time, the vacuum pump will not run smoothly, the reliability will be reduced, and the service life will be short.

Abstract

The invention provides a heat dissipation system of a dry screw vacuum pump, belongs to the technical field of vacuum pumps and solves the problems that the heat generated when screws in the existingdry screw vacuum pump rotate cannot be dissipated and the heat dissipation of the pump body is poor. The heat dissipation system of the dry screw vacuum pump comprises an oil tank, an oil pump and anoil pipe I used for connecting the oil tank with the oil pump, wherein a shaft hole I is formed in a screw I; a shaft hole II is formed in a screw II; an oil pipe component used for transporting oil liquid to the shaft hole I and the shaft II is arranged in the outlet of the oil pump; an oil returning component I is arranged on the screw I; an oil returning component II is arranged on the screw II. The heat dissipation system of the dry screw vacuum pump has the advantages of reasonable structure design and good heat dissipation effect.

Description

technical field [0001] The invention belongs to the technical field of vacuum pumps, and relates to a heat dissipation system of a dry screw vacuum pump. Background technique [0002] The dry screw vacuum pump is a pumping device that uses a pair of screws to perform synchronous high-speed reverse rotation in the pump casing to generate suction and exhaust. The screws are supported by bearings and installed in the pump casing. Between the screws There is a certain gap. When the pump is working, there is no friction between them, the operation is stable, the noise is low, and the working chamber does not need lubricating oil. Therefore, the dry screw pump can pump out the gas containing a large amount of water vapor and a small amount of dust, the ultimate vacuum is higher, the power consumption is lower, and it has the advantages of energy saving and maintenance-free. [0003] For example, a Chinese patent discloses a dry-type screw vacuum pump [the authorized announcement ...
