Embodiment Construction
[0019] Such as figure 1 , Figure 4 and Figure 6 As shown, the present invention is a high-efficiency vacuum pump, which has a high-efficiency multi-outlet electromagnetic locking vacuum machine, and is equipped with an electrical control box matching the equipment. It includes gas nozzle 1 , valve 2 , vacuum gauge 3 , main valve 4 , motor 5 , electromagnetic valve 6 and vacuum pump 7 , which is a technical transformation based on the vacuum pump in the prior art. After the transformation, a new A main air valve 4, three air distribution valves 2 and corresponding three air nozzles 1, and a control box with a solenoid valve and a vacuum gauge 3 are also added to realize the functions of high efficiency, separate control, and automatic locking. The total air valve 4 is arranged on the body of the vacuum pump 7 and is connected in series with the solenoid valve; the three air distribution valves 2 are arranged on the front end of the pump body of the vacuum pump 7 and connec...

The invention relates to a portable vacuumizing pump, and in particular relates to a high-efficiency vacuumizing pump, which is directly applied for maintenance and installation of composite apparatuses on power transformation construction field. The high-efficiency vacuumizing pump comprises air cocks, valves, a vacuum meter, a motor and a vacuum pump. A total air valve is arranged on a vacuum pump body and is connected with an electromagnetic valve; three air distribution valves are arranged on the vacuum pump body and are connected with a pump body air chamber; the three air cocks are connected at positions corresponding to the three air distribution valves; the three air cocks are all connected with the air chamber; the vacuum meter is arranged on the pump body and communicated with the air chamber; and a control cabinet is arranged on the pump body and is connected with the air chamber. The high-efficiency vacuumizing pump solves the problem that the valves are fast switched off due to sudden power cut, can be well controlled in a sealing manner, shorten power cut time, and reduce the economic loss caused due to long repair time. Not only is the vacuumizing efficiency improved, but also the air chamber is conveniently controlled to isolate, and the high-efficiency vacuumizing pump is less in investment, operation personnel is reduced, the labor intensity is reduced, and the hidden safety hazards are lowered, thus the portable vacuumizing pump has wide development prospects and application values.
Description
technical field [0001] The invention relates to a portable vacuum pump, in particular to a high-efficiency vacuum pump. It is directly applied to the maintenance and installation of combined electrical appliances at the substation construction site. It is a high-efficiency vacuum pump that can quickly evacuate the combined electrical appliance maintenance site and at the same time quickly isolate the air chamber. Background technique [0002] At present, the ordinary vacuum pump in the prior art only has a separate air nozzle for vacuuming, and it takes a relatively long time to vacuumize, and the maintenance work efficiency for the combined electrical appliance is low, and the isolation of the air nozzle is not strict, such as figure 2 , image 3 and Figure 5 shown. The structure of the vacuum pump in the prior art only has one valve to control one air nozzle, and the motor is only controlled by a power switch. After the standard, close the valve, and then lock the pow...
