Abstract
The invention discloses one-working one-standby vacuum pump sets for a dust remover, and relates to the technical field of low-temperature refrigeration. The vacuum pump sets comprise a vacuum chamber, a vacuum pump set I, a vacuum valve I, a vacuum pump set II and a vacuum valve II, wherein the vacuum pump set I is connected with the vacuum valve I, the vacuum pump set II is connected with the vacuum valve II, and the vacuum valve I and the vacuum valve II are connected in parallel and then are connected with the vacuum chamber. According to the two vacuum pump sets disclosed by the invention, the two vacuum pump sets are respectively working and standby, so that the requirements of long-time continuous operation of a Stirling refrigerator are satisfied.
Description
Technical field
The present invention relates to low-temperature refrigeration technology field, particularly relate to a kind of deduster and open one for vacuum pump group with one.
Background technique
Sterlin refrigerator reliability testing platform is a kind of special device sterlin refrigerator being carried out to reliability testing, because the continuous duration of the reliability testing of sterlin refrigerator will more than 30000 hours, and supporting vacuum pump group system stream time cannot meet this requirement.
Summary of the invention
The object of this invention is to provide a kind of longevity of service, the vacuum pump group of sterlin refrigerator work requirements can be met.
In order to solve problem existing in background technique, the present invention is by the following technical solutions: it comprises vacuum chamber, vacuum pump group one, vacuum valve one, vacuum pump group two, vacuum valve two, described vacuum pump group one is connected with vacuum valve one, vacuum pump group two is connected with vacuum valve two, is connected after vacuum valve one is in parallel with vacuum valve two with vacuum chamber.
The present invention adopts one group of work, and one group for subsequent use, meets the requirement of sterlin refrigerator long time continuous working.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
See Fig. 1, a kind of deduster opens one for vacuum pump group with one, it comprises vacuum chamber 1, vacuum pump group 1, vacuum valve 1, vacuum pump group 24, vacuum valve 25, described vacuum pump group 1 is connected with vacuum valve 1, vacuum pump group 24 is connected with vacuum valve 25, is connected after vacuum valve 1 is in parallel with vacuum valve 25 with vacuum chamber 1.
After device start, first worked by vacuum pump group one and vacuum valve one, vacuumize, during continuous operation, when any parts of vacuum pump group one break down due to long-play, equipment provides fault message automatically, while closedown vacuum pump group one, provide switching signal, equipment automatically switches to vacuum pump group two for subsequent use, thus ensure that the normal operation of equipment, then fault treatment is carried out, so that for subsequent use to vacuum pump group one.Present invention employs double pump group system, solve the requirement that conventional vacuum pump group system stream time cannot meet sterlin refrigerator reliability testing platform.
Claims (1)
