[0039] In order to increase the compression strength of the base 2 and the compactness of the overall unit, the following embodiments are adopted:

[0040] In this embodiment, the part of the vacuum pump air outlet pipe 4 between the two ports is located inside the base 2, forming an integrated out-gas structure. On the one hand, the vacuum pump air outlet pipe 4 inside the base 2 can fill the base 2 to some extent, which is equivalent to adding multiple reinforcing ribs inside the base 2 to increase the compression strength of the base 2. On the other hand, arranging the vacuum pump air outlet pipe 4 inside the base 2 can reduce the floor area of the overall unit, making it more suitable for a wider range of applications and less limited.

[0041] In order to facilitate the pry-mounted transportation of the overall unit, the following embodiments are adopted:

[0042] In this embodiment, the base 2 is provided with a pry hole 201. When prying, the support arm of the forklift is inserted into the pry hole 201, and the overall pry-mounted transportation of the unit can be realized.

[0043] The protective cover 1 is respectively provided with an air inlet grille 106 and an exhaust fan 107. Through the air inlet grille 106 and the exhaust fan 107, air flow can be formed inside and outside the protective cover 1, the temperature inside the protective cover 1 can be continuously reduced, and the long-term stable operation of the vacuum pump can be ensured.

[0044] In order to further increase the integrated layout of the overall unit, the following embodiment is adopted:

[0053] In this embodiment, Figure 7It can be seen that the vacuum pump exhaust pipe 4 forms a coiled distribution inside the base 2, and the vacuum pump exhaust pipe 4 covers most of the area inside the base 2. On the one hand, it can increase the overall compression strength of the base 2 and enhance the stability of the overall structure of the base 2. On the other hand, the gas transmitted to this position can be compressed again under the action of the curved shape of the vacuum pump exhaust pipe 4, thereby improving the compression efficiency. On the other hand, it can effectively buffer the gas flowing through, further reducing the operating noise.

[0054] The front guard plate 101 is provided with a control panel 108 located near the upper end. The control panel 108 can control the normal start, stop and emergency stop of the motor 6, and is convenient and fast to operate.

[0059] The inside of the protective cover 1 is provided with a reinforcing support plate 9. One end of the reinforcing support plate 9 is fixedly connected with the soundproof cover 8, and the other end of the reinforcing support plate 9 is fixedly connected with the left guard plate 103.

[0060] In this embodiment, the reinforcing support plate 9 is arranged to stably support the soundproof cover 8, thereby avoiding the self-shaking of the soundproof cover 8 and increasing the stability of the connection between the soundproof cover 8 and the Roots vacuum pump 7.

[0061] The bottom of the base 2 is provided with a support block 3. The number of the support block 3 is multiple. The multiple support blocks 3 can form a gap with a certain height at the bottom of the base 2, thereby avoiding the accumulation of foreign matters and rainwater soaking at the bottom of the base 2, and preventing damage to the base 2.

[0062] The left guard plate 103 and the right guard plate 104 are respectively provided with through holes 11 for passing through power lines and related signal lines. The through holes 11 arranged on the left guard plate 103 and the right guard plate 104 can meet the needs of different installation directions, and have a wider application range.
