Embodiment Construction

[0007] See figure 1 , A vacuum pump set with one open and one standby for dust collector, which includes vacuum chamber 1, vacuum pump set one 2, vacuum valve one 3, vacuum pump set two 4, vacuum valve two 5, said vacuum pump set one 2 is connected with vacuum valve one 3. , Vacuum pump group two 4 is connected with vacuum valve two 5, vacuum valve one 3 is connected in parallel with vacuum valve two 5 and then connected to vacuum chamber 1.

[0008] After the equipment is started, the vacuum pump group 1 and the vacuum valve 1 work to vacuum. During continuous operation, when any part of the vacuum pump group 1 fails due to long-term operation, the equipment automatically gives fault information, and the vacuum pump group is closed. A switching signal is given at the same time, and the equipment is automatically switched to the second vacuum pump group to ensure the normal operation of the equipment, and then the vacuum pump group one is fault-handled for backup. The invention ...

Abstract

The utility model relates to a vacuum pump set for a dust collector, which relates to the technical field of low-temperature refrigeration. It includes a vacuum chamber, a vacuum pump group 1, a vacuum valve 1, a vacuum pump group 2, and a vacuum valve 2. The vacuum pump group 1 is connected to the vacuum valve 1, and the vacuum pump group 2 is connected to the vacuum valve 2. Connect to the vacuum chamber. The invention adopts one group of working and one group of standby, which meets the requirement of long-term continuous operation of the Stirling refrigerator.

Description

Technical field [0001] The invention relates to the technical field of low-temperature refrigeration, and in particular to a vacuum pump set for a dust collector with one opening and one backup. 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 matching vacuum pump set The continuous working time of the system cannot meet this requirement. Summary of the invention [0003] The purpose of the present invention is to provide a vacuum pump unit that has a long working time and can meet the working requirements of a Stirling refrigerator. [0004] In order to solve the problems in the background art, the present invention adopts the following technical solutions: it includes a vacuum chamber, a vacuum pump set 1, a vacuum valve 1, a vacuum pump set two, and a vacuum valve 2. The vacuum pump set ...
