Abstract
An exhaust casing assembly used for a test piece of a gas compressor comprises an outlet casing assembly, a front exhaust outer ring section, a front exhaust inner ring section, a test lead, an exhaust casing connecting ring, a rear exhaust outer ring section, a rear exhaust inner ring section and a balancing disc sealing ring. The whole casing assembly is formed through assembly of the exhaust casing connecting ring. The front end of the outlet casing assembly is connected with an outlet of the gas compressor. The rear end of the rear exhaust outer ring section is connected with a rear exhaust section of the test piece of the gas compressor. The outlet casing assembly and the rear exhaust outer ring section are connected with a front component and a rear component in an overlapped mode. The outlet casing assembly, the front exhaust inner ring section, the rear exhaust outer ring section and the rear exhaust inner ring section are of cantilever structures.

Wherein: form a complete casing assembly parts by the assembling of exit casing coupling ring, front end exit casing assembly parts 1 connects with blower outlet, rear end exhaust outer shroud back segment 7 connects with Compressor test part final vacuum section, outlet casing assembly parts 1 and exhaust outer shroud back segment 7 overlap with front and back parts and are connected simultaneously, knockdown export casing assembly parts 1, exhaust inner ring leading portion 3, exhaust outer shroud back segment 7 and exhaust inner ring back segment 8 are cantilever structures, and this structure ensure that the assembling of whole exit casing assembly parts there will not be the situation of Planar Mechanisms.The exit casing assembly parts proposed by the present invention, effectively reliably can ensure the integrity of Compressor test part, meet the requirement of testpieces balance dish simultaneously, by the switching of exit casing assembly parts, the test of Compressor test part also can be realized, functional requirement that stand bleed, testpieces lead to air etc.
The inner and outer rings casing of testpieces is divided into 4 sections by described exit casing coupling ring 5, sees Fig. 1.
After testpieces rotor, design a Balance disc, see Fig. 1, carry out the axial force of blance test part, the safe operation of proof test part.
The present invention proposes a kind of exit casing assembly parts, see Fig. 1, except testpieces final vacuum section support plate, turn increase the load position of casing inside and outside a place, i.e. exit casing coupling ring.By the supporting of exit casing coupling ring, achieve connecting of compressor casing and exhaust section, and ensure that the assembling of gas compressor Balance disc.
Realize the smooth transfer of blower outlet stream and exhaust section, ensure the smooth discharge of air-flow, simultaneously because testpieces needs to adopt balancing disc structure, rear inner ring casing is equipped with coating ring of obturaging and carrys out the use of complex equilibrium dish.
The inner and outer rings casing of testpieces is divided into 4 sections by exit casing coupling ring simultaneously, ensure that the realization that testpieces back segment assembles.
As from the foregoing, the use of exit casing assembly parts, ensure that the realization of the integrity of testpieces casing, Balance disc function, site-assembled feasible.
Advantage of the present invention:
The exit casing assembly parts that can be used for Compressor test part of the present invention, be applied on the Compressor test part of high pressure ratio, large discharge, while meeting the requirements such as Compressor test part balancing axial thrust, grate flow channel switching, also can the related needs such as testability, assembling, reliability, maintainability of proof test part, be a kind of optimal case of Compressor test part Universal Exhaust Gas section.
