The testing stand of researching rotation characteristics of part of components in a fluid system includes the following components: a rotation stand rack (1), bearings (3), a rotating shaft (4), a shaft sleeve (5), a variable frequency motor (9) and a fixed foot rest (12); the rotation stand rack (1), the bearing (3), the rotating shaft (4), the shaft sleeve (5), the variable frequency motor (9) and the fixed foot rest (12) are used for mounting research object apparatus; the surface of the rotation stand rack (1) is provided with a screwed hole (11) for mounting research components; the rotating shaft (4) and the rotation stand rack (1) are connected through a flange, and are fixed by means of a plurality of bolts (2); a standstill locking hole (6) and a plurality of connection holes (7) are formed in the shaft sleeve (5); and a plurality of fluid channels (10) are formed in the rotation stand rack (1) and the rotating shaft (4). The testing stand of researching rotation characteristics of part of components in a fluid system can be used for researching the operating characteristics of the fluid in the part of components in the system in different overload environment, and has the advantages of being simple in structure, being simple to operate, and being efficient in operating.

Description

technical field [0001] The invention relates to a test bench and method for studying the rotational characteristics of some parts of a fluid system, belonging to the technical field of aerospace. Background technique [0002] With the development of the aerospace industry, the overload characteristics of the fluid system inside the aircraft have attracted much attention, such as the air cycle refrigeration system, the evaporative cycle refrigeration system in the environmental control system, and the cooling system of the aircraft equipment. These systems all involve the working characteristics of the fluid under different overloads. [0003] For example, when a fighter jet is doing ordinary high-speed maneuvering flight, the overload on the fuselage can reach 6-9g in value. During the high-speed flight of modern top fighter jets, the overload may rise to 12g within one second. Various systems and components on the aircraft, including the onboard evaporative cycle refrigera...

Problems solved by technology

[0005] However, the current domestic rotary test benches are too large in size, and the purpose is to place the entire fluid system on the rotary bench to study the flow characteristics of the fluid in a certain component

Therefore, the construction and arrangement of the system on the turntable is particularly complicated, and a lot of manpower and material resources will be wasted
