Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0022] An external plug-in test sensing part installation structure for a three-layer casing, such as figure 2 As shown, it includes an outer casing 1 , an inner casing 2 , an outer casing 3 , an inner casing 4 and a test sensing part 5 . Outer casing outer casing 1, outer casing inner casing 2, inner outer casing 3, and inner inner casing 4 are all ring-shaped casings and each casing is coaxially arranged, and outer casing outer casing 1 and outer casing inner Outer flow passages are formed between the casings 2, and inner flow passages are formed between the inner outer casing 3 and the inner casing 4.

[0023] The outer culvert outer casing 1 and the outer culvert inner casing 2 are provided with corres...

Abstract

The invention belongs to the field of sensing part installation design, and relates to an external insertion type test sensing part installation structure for a three-layer casing, which comprises an outer culvert outer casing, an outer culvert inner casing, an inner culvert inner casing and a test sensing part, and when the test sensing part is assembled, the installation structure does not need to be arranged between the outer culvert inner casing and the inner culvert outer casing, so that the test sensing part can be conveniently assembled. The measurement section can be inserted between the outer culvert inner casing and the outer culvert inner casing only through the outer culvert outer casing and the outer culvert inner casing, the installation process is simple and easy to operate, the assembly of the multi-layer casing is not influenced, the assembly in the test piece assembly process is not needed, and the assembly can be carried out on a rack; during installation, the test sensing part is directly inserted inwards from the outer side of the casing, the measurement section can be sent to a designated position, and then the test sensing part and the outer casing of the outer culvert are fixed on the outer side of the casing. And when the test sensing part is damaged, the detachably and fixedly connected mounting structures are separated, so that the test sensing part can be directly pulled out, and the use is convenient.

Description

technical field [0001] The application belongs to the field of installation and design of a sensing part, and in particular relates to an installation structure of an external plug-in test sensing part for a three-layer casing. Background technique [0002] The outlet of the fan performance test piece or the double-duct compressor performance test piece is composed of two ducts, the inner and outer ducts, such as figure 1 As shown, wherein the outer casing of the whole ring and the outer casing of the whole ring form the outer casing, and the inner casing of the whole ring and the inner casing of the whole ring form the inner casing. In order to measure the pressure or temperature parameters inside the outlet of the fan / compressor, the test sensing part is usually fixed on the inner outer casing with screws, and the test leads on the test sensing part are formed in the outer casing inner casing and the inner outer casing. The cavity is drawn backward, and passes through the...
