Problems solved by technology

For industrial wastewater, its pressure can reach several MPa or even dozens of MPa, but it is not realistic to simply increase the liquid level of the imported liquid in order to obtain high-pressure liquid in the experiment, so a high-pressure pump is needed to pressurize the liquid
In addition, the ordinary test bench does not have automatic control function, and its parameters such as pressure and flow are poorly adjustable, and it is not convenient to record the external characteristic parameters of the hydraulic turbine under different working conditions

Abstract

The invention discloses a high-pressure waste energy recovery hydraulic turbine test stand and control method thereof, which belongs to the field of measuring equipment. The relevant experiment platform and the control method thereof are provided for a high-pressure waste energy recovery hydraulic turbine. The test stand mainly comprises the hydraulic turbine, a generator, an inverter motor, a high-pressure piston pump, a relief valve, an electric control valve, a heating device, a turbine flow meter, a temperature sensor, a pressure transmitter, a pressure gauge, a pool and a torque tachometer. Compared with an ordinary test stand, the high-pressure waste energy recovery hydraulic turbine test stand has the advantages that automatic relevant component control and automatic information collection are realized; pressure, flow and other parameters are adjustable in a turbine running process; the working condition of the turbine can be efficiently recorded and the working characteristics are analyzed; and the research and the development of the novel high-pressure waste energy recovery hydraulic turbine are convenient.

Description

technical field [0001] The invention belongs to the field of measuring equipment, in particular to a test platform for performance testing of a high-pressure residual energy recovery hydraulic turbine and a control method thereof. Background technique [0002] Today, when the world's energy is becoming increasingly tense, hydraulic turbines, as an energy recovery device, are gradually used in industrial production and have achieved good results, effectively saving energy and alleviating the current situation of energy shortage. However, the development of hydraulic turbines for energy recovery in high-pressure medium is still in an immature stage, and the research on the performance of high-pressure residual energy recovery hydraulic turbines needs to be based on a large number of experiments. [0003] Different from ordinary pump test benches and ordinary turbine test benches, the imported working fluid of high-pressure residual energy recovery hydraulic turbines is high-pr...
