[0011] Using the above technical solution, the first motor is fixed to the upper end of the support base by the support seat. The first motor drives the first pulley to rotate, and the first pulley, together with the first transmission belt, drives the second pulley to rotate, providing power for the operation of the pump body. The design of pulleys with different diameters can reduce the load on the motor during operation and prevent the motor from burning out.

[0012] Preferably, the protective housing has an air intake grille installed at the front and rear ends on the left side, and the air intake guide pipe is connected to the outside through the air intake grille. The impeller is rotatably connected to the air intake guide pipe.

[0013] By adopting the above technical solution, through the cooperation of the impeller and the air intake guide pipe, external air can be continuously drawn into the protective shell through the air intake grille. After flowing inside the protective shell, it flows out through the air outlet grille, carrying away the heat inside the protective shell and preventing the pump body and the first motor from overheating.

[0014] Preferably, two sets of air intake guide pipes are symmetrically arranged, and the air intake guide pipes are symmetrically installed at the two left corners of the protective housing.

Furthermore, by utilizing the cooperation of the drive pulley and the second drive belt, rotational power can be provided to both sets of wind turbines simultaneously.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the air-cooled vertical oil-free vacuum pump;

[0019] 1. By setting up an air intake structure, it can continuously draw outside air into the protective housing and let it flow inside the protective housing, and dissipate the heat inside the protective housing. This not only dissipates heat from the pump body, but also prevents the pump body from generating high temperatures during long-term operation of the first motor, thus ensuring the stable operation of the vacuum pump.

[0020] 2. The vacuum pump is protected by a protective housing to prevent it from being bumped or knocked during use. This is to prevent damage to the internal components caused by the high-speed movement of the internal components during operation. Attached Figure Description
