The invention discloses a refrigeration expansion machine performance testing device with zero nitrogen consumption. The device comprises a liquid nitrogen storage tank, a liquid nitrogen pump, a first gasifier, a second gasifier, an electric heater, a buffer tank, a filter, a multi-channel heat exchanger, a main compressor, a first power recovery compressor, a second power recovery compressor, a first refrigeration expansion machine, a second refrigeration expansion machine, a first circulating water cooler, a second circulating water cooler, a third circulating water cooler, an economizer, and a throttle valve, wherein the first circulating water cooler, the second circulating water cooler and the third circulating water cooler are provided with circulating cooling water; the first power recovery compressor is driven by the first refrigeration expansion machine; and the second power recovery compressor is driven by the second refrigeration expansion machine. The device can provide nitrogen with proper temperature and pressure for the refrigeration expansion machine to be tested to enable the refrigeration expansion machine to continuously work, so that the performance of the refrigeration expansion machine can be tested; and the device can cyclically utilize the nitrogen for testing, so that zero consumption of the nitrogen, energy conservation and emission reduction can be realized.
Description
technical field [0001] The invention relates to the field of testing equipment, in particular to a performance testing device for a refrigeration expander with zero nitrogen consumption. Background technique [0002] The current hydrogen liquefaction process generally uses a nitrogen refrigeration cycle to precool hydrogen and a high-pressure hydrogen isentropic expansion refrigeration cycle to liquefy hydrogen, and the key equipment is a nitrogen refrigeration expander and a hydrogen refrigeration expander. At present, there is no performance test device for testing the performance of hydrogen refrigeration expanders and nitrogen refrigeration expanders, because the working temperature of hydrogen refrigeration expanders and nitrogen refrigeration expanders is relatively low, and general performance testing devices cannot be used. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a performance test device for a re...
