Abstract
The utility model discloses a one-operation-and-one-standby vacuum pump set, and relates to the technical field of low-temperature refrigeration. The one-operation-and-one-standby vacuum pump set comprises a vacuum chamber, a first vacuum pump set, a first vacuum valve, a second vacuum pump set and a second vacuum valve. The first vacuum pump set is connected with the first vacuum valve, the second vacuum pump set is connected with the second vacuum valve, and the first vacuum valve is connected with the second vacuum valve in parallel to be then connected with the vacuum chamber. By means of the one-operation-and-one-standby vacuum pump set, one set of devices are standby while the other set of devices work, and the long-time continuous working requirement of a Stirling refrigerator is met.
Description
Technical field
The utility model relates to low-temperature refrigeration technology field, relates in particular to a kind of vacuum pump group.
Background technique
Sterlin refrigerator reliability testing platform is sterlin refrigerator to be carried out to a kind of special device of reliability testing, because the continuous duration of the reliability testing of sterlin refrigerator will be more than 30000 hours, and supporting vacuum pump group system stream time cannot meet this requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of longevity of service, can meet the vacuum pump group of sterlin refrigerator work requirements.
In order to solve existing problem in background technique, the utility model 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, after vacuum valve one is in parallel with vacuum valve two, is connected with vacuum chamber.
The utility model adopts one group of work, and one group standby, has met the requirement of sterlin refrigerator long time continuous working.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of one opens one for vacuum pump group, 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, after vacuum valve 1 is in parallel with vacuum valve 25, is connected with vacuum chamber 1.
After device start, first by vacuum pump group one and vacuum valve one work, vacuumize, during continuous operation, when any parts of vacuum pump group one break down due to long-play, equipment provides fault message automatically, when closing vacuum pump group one, provide switching signal, equipment automatically switches to standby vacuum pump group two, thereby has guaranteed the normal operation of equipment, then vacuum pump group one is carried out to fault treatment, so that standby.The utility model has adopted double pump group system, has solved the requirement that conventional vacuum pump group system stream time cannot meet sterlin refrigerator reliability testing platform.
Claims (1)
