A performance testing system for a scroll expander

Abstract

The present invention relates to a scroll expander performance test system. The scroll expander performance test system comprises an air compressor module, a gas adjusting module, a temperature control module, a dynamometer module, an upper computer and a backpressure adjusting module. The air compressor module, the gas adjusting module and the temperature control module are connected orderly, and the temperature control module is connected with a scroll expander (20) via a reversing valve (14). The dynamometer module and the backpressure adjusting module are both connected with the scroll expander (20), and the data acquired by the dynamometer module is uploaded to the upper computer via an MCGS software. Compared with the prior art, the scroll expander performance test system of the present invention has the advantages of being simple in structure, being convenient to maintain, etc.

Description

technical field [0001] The invention belongs to the technical field of waste heat recovery, and in particular relates to a performance testing system of a scroll expander. Background technique [0002] At present, in terms of energy utilization in my country, there are mainly a series of problems such as low utilization efficiency, poor economic benefits, a large waste of waste heat, and high pressure on the ecological environment, and these problems are concentrated in the industrial field with the largest energy consumption. According to the relevant data given by the National Statistical Yearbook, in 2014, industry accounted for 69.8% of the energy consumption of various industries in my country. However, due to reasons such as backward production technology and unreasonable industrial structure, less than 50% of the nearly 70% of the industrial energy is actually used for production, and the remaining more than 50% of the energy is directly or indirectly in the form of w...

Problems solved by technology

However, due to reasons such as backward production technology and unreasonable industrial structure, less than 50% of the nearly 70% of the industrial energy is actually used for production, and the remaining more than 50% of the energy is directly or indirectly in the form of waste heat. emitted into the surrounding atmosphere

[0005] The technical solution disclosed in the above patent is mainly aimed at the performance test of the screw expander, and the working medium used has a state change, which is not suitable for the scroll expander; in addition, the structure of the closed-loop system is complicated, and installation and maintenance are inconvenient; the output of the expander As far as the collection of parameters is concerned, only the output power can be obtained, and the speed, torque, etc. cannot be obtained directly, and the reverse performance experiment cannot be carried out, that is, the performance experiment of the influence of the load change of the expander on its speed cannot be carried out.
