Test tool for multi-plunger type pipeline assembly

Abstract

The invention provides a test tool for a multi-plunger type pipeline assembly. The test tool comprises a positioning base provided with a positing platform, a positioning cylinder, connecting bosses and jacks. The positioning platform is connected with an inlet flange through a fastener and is provided with connecting holes corresponding to fixing holes in the inlet flange. The cylinder wall of the positioning cylinder is in contact with a pipeline to reduce the pipeline deformation. The connecting bosses are arranged on the positioning base in a protruding manner and are provided with outer threads; the connecting bosses are used for threaded connection with connecting nuts to fix the end portion of the pipeline to the positioning base. The jacks are formed in the connecting bosses and the positioning base and are used for plunger insertion of a multi-plunger type pipeline assembly in threaded connection of the connecting nuts with the connecting bosses; and blocking materials for blocking a liquid outlet of the plunger are arranged at the bottoms of the jacks. The test tool has the following beneficial effects: the two ends of the pipeline assembly are fixed and the middle pipeline is limited by the positioning cylinder, so that the test operation becomes convenient; and the deformation of the pipeline assembly is reduced and the shape correcting procedure can be omitted after a test is finished, so that the cost is saved.

Description

technical field [0001] The invention relates to a test fixture of a multi-plunger pipeline assembly. Background technique [0002] The multi-plunger pipeline assembly is the mechanical connection part of the oil collection and injection system, and is widely used in large hydraulic equipment such as aviation, aerospace engines, and gas turbines. A multi-plunger pipeline assembly in the prior art such as figure 1 As shown, the multi-plunger pipeline assembly 1 includes an inlet flange 11 and a plurality of pipelines 15 fixed on the inlet flange 11. The lengths of each pipeline 15 are different and curved. The ends are all welded and fixed with a plunger 14 , and each pipeline 15 is also sleeved with a connecting nut 13 . When in use, the multi-plunger pipeline assembly 1 is fixed on the hydraulic equipment through the fixing hole 12 provided on the inlet flange 11, and each pipeline 15 is fixedly connected to the interface on the oil supply position by using the connecting ...

AI Technical Summary

Problems solved by technology

However, there is no suitable test tooling at present, which is inconvenient for the test operation, and the pipeline is easily deformed after being fed with a certain pressure medium. After the test, it is necessary to increase the shape correction process. Difficulty ensuring component dimensional consistency and assembly interchangeability
