Embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with the accompanying drawing in embodiment, to reality
The technical scheme applied in example is clearly and completely described, it is clear that described embodiment is only that the application part is implemented
Example, rather than whole embodiments.Based on the embodiment provided, those of ordinary skill in the art are not before creative work is made
The every other embodiment obtained is put, belongs to the scope of the application protection.
In the description of the present application, term " first ", " second " etc. be only used for describe purpose, and it is not intended that instruction or
Imply relative importance or the implicit quantity for indicating indicated technical characteristic.
A kind of parallel pumped vacuum systems, including vaccum-pumping equipment 2 and first, second condense cooling device 3,4, described to take out
Vacuum equipment 2 and first, second condenses the composition of cooling device 3,4 at least one-level vacuum extractor, parallel vacuumize
Include discharge 5 in system, be the first vacuum operated equipment 1a separate, in parallel, the second vacuum before the discharge 5
Operation equipment 1b, the 3rd vacuum operated equipment 1c pass through each self-corresponding first motor-driven valve 6a, the second motor-driven valve 6b, the 3rd electronic
Valve 6c and pipeline are connected with the discharge 5, are the vacuum extractor after the discharge 5；Parallel vacuumize be
System also includes automatic control system, the first motor-driven valve 6a, the second motor-driven valve 6b, the 3rd motor-driven valve 6c and the first vaccum-pumping equipment
2a, the second vaccum-pumping equipment 2b, controlled by automatic control system.
Preferably, first check-valve 7a, are additionally provided with the pipeline that each vacuum operated equipment connects with discharge
Two check-valves 7b, the 3rd check-valves 7c, because the connecting line of vacuum operated equipment and discharge cooling can produce it is a certain amount of
Condensate liquid pass back into vacuum operated equipment and prevent magnetic valve open after the higher vacuum behaviour of other pressure in parallel pipeline
