Embodiment Construction

[0007] see figure 1 , a vacuum pump group with one opening and one preparation, which includes a vacuum chamber 1, a vacuum pump group one 2, a vacuum valve one 3, a vacuum pump group two 4, and a vacuum valve two 5, the vacuum pump group one 2 is connected with the vacuum valve one 3, and the vacuum pump Group 2 4 is connected with vacuum valve 2 5, and vacuum valve 1 3 is connected with vacuum chamber 1 after being connected in parallel with vacuum valve 2 5.

[0008] After the equipment is started, the vacuum pump group 1 and the vacuum valve 1 work first to pump the vacuum. During continuous operation, when any part of the vacuum pump group 1 fails due to long-term operation, the equipment will automatically give a fault message, and then close the vacuum pump group. When a switching signal is given at the same time, the equipment automatically switches to the standby vacuum pump group 2, thus ensuring the normal operation of the equipment, and then the vacuum pump group 1...

Abstract

The invention discloses a one-open and one-standby vacuum pump set, and relates to the technical field of low-temperature refrigeration. The one-open and one-standby vacuum pump set comprises a vacuum cavity, a vacuum pump set I, a vacuum valve I, a vacuum pump set II and a vacuum valve II; 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 is connected with the vacuum cavity after being connected with the vacuum valve II in parallel. The one-open and one-standby vacuum pump set satisfies long-time continuous working requirement of a stirling cryocooler by adopting one set to work and one set to standby use.

Description

technical field [0001] The invention relates to the technical field of low-temperature refrigeration, in particular to a vacuum pump group. Background technique [0002] The Stirling refrigerator reliability test bench is a special equipment for reliability testing of Stirling refrigerators. Since the reliability test of Stirling refrigerators lasts for more than 30,000 hours, the supporting vacuum pump set The continuous working time of the system cannot meet this requirement. Contents of the invention [0003] The purpose of the present invention is to provide a vacuum pump group with a long working time, which can meet the working requirements of the Stirling refrigerator. [0004] In order to solve the existing problems in the background technology, the present invention adopts the following technical solutions: it includes a vacuum chamber, a vacuum pump group 1, a vacuum valve 1, a vacuum pump group 2, and a vacuum valve 2, and the vacuum pump group 1 is connected t...
