The enforcement the beneficial effects of the utility model are: vacuum pump comprises inert gas tube, and inert gas tube extend into below the pasta of vacuum oil; Pass into inert gas in inert gas tube, inert gas enters along inert gas tube in the cavity of vacuum pump, increases the air pressure in the cavity, makes the poisonous and harmful in the cavity, corrosive gas in time discharge vacuum pump; Thereby reduce the time of contact of poisonous and harmful, corrosive gas and vacuum oil, avoid residual in cavity of poisonous and harmful, corrosive gas, prolonged greatly the working life of vacuum pump and vacuum oil, reduced operating cost, reduced environmental pollution.
Description of drawings
Fig. 1 is the structural representation of a kind of vacuum pump with protective gear of the utility model.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1; vacuum pump with protective gear comprises vacuum pump main body 1, blow-down pipe 3 and suction tude 4; described vacuum pump main body 1 comprises cavity 11; be provided with vacuum oil 111 in the described cavity 11; described vacuum pump also comprises inert gas tube 2, and an end of described inert gas tube 2 extend into below the pasta of described vacuum oil 111.
Need to prove, blow-down pipe 3 all communicates with cavity 11 with suction tude 4, simultaneously all be fixed by welding in cavity 11 on cover, be conducive to like this guarantee the sealing of vacuum pump; The device that suction tude 4 outer termination need vacuumize, blow-down pipe 3 outer termination exhaust gas processing devices, a large amount of poisonous and harmfuls, the corrosive gas that contain in the gas that can avoid like this being drawn out of directly enter in the air, cause the pollution to environment; Inert gas tube 2 is hard tube, be fixed by welding in cavity 11 on cover, thereby guarantee the sealing of vacuum pump; The external section of inert gas tube 2 connects inert gas source (not marking among Fig. 1).
Vacuum pump when work, open simultaneously inert gas tube 2, inert gas is entered in the cavity 11 along inert gas tube 2, increase the air pressure in the cavity 11, thereby make the gas that is drawn into the cavity 11 from suction tude 4 in time discharge cavitys 11 from blow-down pipe 3.
More preferably, described inert gas tube 2 is provided with gas valve 21.
Need to prove, gas valve 21 is conducive to control the switching of inert gas tube 2 and the flow of control inert gas.
More preferably, described inert gas tube 2 is provided with flowmeter 22.
Need to prove, flowmeter 22 is conducive in time grasp the uninterrupted of inert gas, so that in time adjust when needing.
More preferably, described inert gas tube 2 comprises external and built-in section, and described external section connects inert gas source, and described built-in section is located in the cavity 11; Described built-in section is " L " type, and described built-in section comprises vertical component effect 23 and horizontal part 24, and described horizontal part 24 is located at below the pasta of described vacuum oil 111.
