Two-stage air-suspending centrifugal air compressor comprehensive performance test-bed

Abstract

The invention discloses a two-stage air-suspending centrifugal air compressor comprehensive performance test-bed which comprises a primary air inlet end pipeline, a secondary discharge end pipeline, acooling air discharge pipeline and a cooling water circulation pipeline. The two-stage air-suspending centrifugal air compressor comprehensive performance test-bed provided by the invention has the beneficial effects that the performance test-bed is scientific and reasonable in structure design, and high in automation degree; and through a series of sensors arranged on the device, multiple data can be measured, and the measured data is comprehensive, so that the demand on the dependence test of performances of an air compressor can be met, the two-stage air-suspending centrifugal air compressor comprehensive performance test-bed is applicable to air supply performance tests, water cooling performance tests and air cooling performance tests of air compressors and air supply systems in multiple models and under multiple working conditions, the working efficiency and the accuracy are greatly improved, an ergonomic design is favorable, and the test and working environment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a comprehensive performance test bench for a two-stage air suspension centrifugal air compressor. Background technique [0002] The performance parameters of the air compressor, such as displacement, exhaust pressure, etc., refer to the data under the design working conditions, but in the actual use of the compressor, due to the deviation between the inlet pressure and the inlet temperature and the design working conditions, Its performance parameters will also change accordingly, so the performance parameters of the air compressor are not only related to product parameters, but also directly affected by factors such as intake pressure and ambient temperature. In view of the difference between the design working conditions and the actual use process, it is necessary to monitor the performance of the air compressor. At present, there are three main types of air compressor...

AI Technical Summary

Problems solved by technology

[0003] Manual interception detection, using this detection method, nozzles of different specifications must be replaced for different working conditions, the test is cumbersome, the operation is complicated, and the applicability is limited; moreover, all the detection process is done manually, and the test results are greatly affected by human factors , high labor cost and low efficiency

[0004] The control and monitoring system is mainly to detect the working status of the air compressor to judge whether the air compressor is working well. The equipment is complex, the requirements are strict, and the cost is high. It is only suitable for monitoring the working status of high-end precision equipment, and the scope of use is narrow.

[0005] The air compressor efficiency detection system only detects the working status of the air compressor under specific working conditions, and cannot monitor the working status or performance test of different working conditions and types of air compressors; The function of the machine to adjust the air compressor
