Abstract

The invention belongs to the Stirling solar power generation technology, and relates to a test bench for the performance of a sealing device on a Stirling engine piston assembly. The test bench is characterized by comprising an electrical cabinet (15), an electric motor (16), a first coupling (17), a torque sensor (18), a second coupling (17a), a first leak detector (19), a first solenoid valve (20), a second leak detector (19a), a second solenoid valve (20a), a manual pressure regulating valve (21), a gas cylinder (22), an air cylinder unit (23), a flywheel (24), a crankcase (25) and a base (26). The test bench solves the testing problem of the performance data of the sealing device on the Stirling engine, and provides a data support for material selection and design and service long prolongation of the sealing device.

Description

technical field [0001] The invention belongs to the Stirling solar power generation technology, and relates to a test bench for testing the sealing performance of the engine piston assembly of a Stirling solar power generation device. Background technique [0002] The sealing device on the engine piston assembly is one of the key components affecting the performance of the Stirling engine. The quality of the sealing performance will directly affect the power and efficiency of the Stirling engine. Improving the service life of the sealing device can increase the continuous working time of the engine. Extend the engine overhaul cycle and reduce maintenance costs. The structure of the sealing device on the present a kind of engine piston assembly sees figure 2 , which consists of piston 1, piston upper sealing ring 2, piston lower sealing ring 3, piston rod upper sealing ring 4, sealing seat upper sealing ring 5, sealing seat 6, sealing seat lower sealing ring 7, cylinder shel...
