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

Example Embodiment

[0031] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0032] Such as figure 1 As shown, a performance test system for a scroll expander. When in use, the outlet end of the air compressor 1 is connected to the first stop valve 2, the gas tank 5, the second stop valve 6, the dryer 7, the filter 8, and the The pressure reducing valve 9, the regulating valve 10, and the heater 11 are connected, and the outlet end of the heater 11 is connected to the inlet end of the reversing valve 14. After passing through the reversing valve 14, it is divided into two outlets, one outlet is directly connected to the atmosphere The other outlet is connected to the scroll expander 20 and the needle valve 24 in turn. The output shaft of the scroll expander 20 is connected to the dynamometer 19 for real-time monitoring of the output power, torque, speed, etc. of the scroll expander 20 In addition, the dynamometer controller 17 is used...

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...
