Abstract

The invention discloses a refrigeration expansion machine performance testing device which comprises a liquid nitrogen storage tank, a liquid nitrogen pump, a first gasifier, a second gasifier, an electric heater, a buffer tank, a filter and an emptying pipeline, the liquid nitrogen storage tank is connected with the liquid nitrogen pump through a pipeline, and an outlet of the liquid nitrogen pump is connected with inlets of the first gasifier and the second gasifier through pipelines. Outlets of the first gasifier and the second gasifier are respectively connected with an inlet of the electric heater through pipelines, an outlet of the electric heater is connected with an inlet of the buffer tank through a pipeline, an outlet of the buffer tank is connected with an inlet of the filter through a pipeline, and an outlet of the filter is connected with an inlet of the refrigeration expansion machine through a pipeline. An outlet of the hydrogen refrigeration expansion machine is connected with one end of an emptying pipeline, and the other end of the emptying pipeline is connected with the atmosphere. The performance testing device for the refrigeration expansion machine can provide nitrogen with proper temperature and pressure for the refrigeration expansion machine to enable the refrigeration expansion machine to work continuously, so that the performance of the refrigeration expansion machine is tested.

Description

technical field [0001] The invention relates to the field of testing equipment, in particular to a performance testing device for a refrigeration expander. 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 refrigeration expander performance testing device capable of te...
