Embodiment Construction

[0007] see figure 1 , a kind of dust remover with one opening and one preparation vacuum pump group, it comprises vacuum chamber 1, vacuum pump group one 2, vacuum valve one 3, vacuum pump group two 4, vacuum valve two 5, described vacuum pump group one 2 is connected with vacuum valve one 3 , the vacuum pump group two 4 is connected with the vacuum valve two 5, and the vacuum valve one 3 is connected with the vacuum chamber 1 after being connected in parallel with the vacuum valve two 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 ...

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 [0001] The invention relates to the field of low-temperature refrigeration technology, in particular to a vacuum pump set for a dust collector. 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 gr...
