Problems solved by technology

[0003] At present, the existing small-scale compressor closed cycle system often chooses the gas supply bottle as the working medium gas supply device. If the pressure of the gas supply bottle is lower than the inlet pressure of the experimental system, the gas cylinder needs to be replaced, and the cost is high; the control of the gas supply bottle The precision requirement is high, if there is an untimely or insufficient air supply, it is easy to cause the compressor to surge and cause a safety accident; special working fluids may be harmful to the environment, and there is a certain degree of safety if the air supply bottle is used for recycling Hidden danger

Embodiment 1

[0047] Such as figure 2 As shown, under general working conditions, during the experiment of the compressor closed-circuit experimental system, the air supply cut-off valve 16, the air supply cut-off valve 18, the main flow regulating valve 19 and the auxiliary flow regulating valve 20 are first opened, and the air discharge stop valve is closed. 8. The main air release valve 9 and the auxiliary air release valve 10, when the pressure of the working medium in the compressed gas pipeline of the compressor closed experimental system reaches the required value of the experimental inlet pressure of the tested compressor 25, close the main flow adjustment Valve 19 and auxiliary flow regulating valve 20. Afterwards, when the pressure of the working medium in the gas supply tank 17 reaches the required value of the gas supply pressure (the required value of the gas supply pressure is obtained according to the leakage of the measured compressor 25 and the test time), the gas supply c...

Embodiment 2

[0055] see image 3 , the difference between this embodiment and Embodiment 1 is that in this embodiment, since the test pressure of the compressor 25 under test is relatively high, the closed experimental system of the compressor is in a high-pressure working condition, and the pressure stabilizing unit of the gas source device is not connected during the test. Do not run, now the pressure of the working medium in the buffer tank 7 and the surge tank 2 is relatively low, and the pressure in the gas storage tank 17 is relatively high (guaranteeing the gas replenishment capacity of the compressor 25 under test and the requirements of the test time), and the solenoid valve 14 maintains In the closed state, the solenoid valves 12 and 13 remain open, and the working medium flows into the buffer tank 7 and the surge tank 2 through the deflation unit for storage.

[0056] To sum up, the gas source device used in the compressor closed experimental system proposed by the present inven...

Abstract

The invention discloses an air source device for a compressor closed type experiment system and a control method of the air source device. The air source device comprises an air supplementing unit, anair discharging unit and a pressure stabilizing unit. According to the air source device, the self-circulation of a working medium can be completed through the pressure stabilizing unit (including apressure stabilizing tank, a compressor and other components), the recycling function of the working medium can be achieved, and the testing capacity of the compressor closed type experiment system iseffectively expanded. According to the air source device, the air supplementing unit and the air discharging unit are arranged such that the air supplementing and discharging of the compressor closedtype experiment system can be achieved, the rapid surge relief of a tested compressor can be realized by dynamically monitoring the outlet pressure fluctuation of the tested compressor and operatinga main vent valve. The air source device disclosed by the invention belongs to the related technical field of centrifugal or axial flow compressor testing, is suitable for stable working media such asair, carbon dioxide, nitrogen and the like, and is also suitable for inflammable, explosive and corrosive working media such as hydrogen gas, ammonia gas and the like.

Description

technical field [0001] The invention belongs to the technical field of compressed air energy storage, relates to the related technical field of centrifugal or axial flow compressor testing, and in particular relates to an air source device and a control method thereof for a closed experimental system of a compressor. Background technique [0002] Combined with the characteristics of the compressed air energy storage system, the compressors used are usually centrifugal or axial flow. Carrying out relevant experiments and tests on the compressors can realize the performance appraisal of new compressor products and provide performance curves and quality for the designed prototypes. testing method. According to the different types of experiments, the compressor experimental system can be divided into two types: open type and closed type. Among them, the open type experimental system can only realize the performance experiment of the compressor with air as the medium or other med...
