Abstract
The utility model relates to a welded wall static pressure testing device for a thin-walled workpiece. The device is characterized by comprising a test bench main body, a sealed rubber layer and a lead tube, wherein the test bench main body is provided with a test hole in a vertical direction and a lead hole in a horizontal direction, which are communicated with each other, the test bench main body is adhered to the thin-walled workpiece through the sealed rubber layer, and the lead tube is inserted into the hole in a horizontal direction of the test bench main body. The device provided by the utility model has the advantage of being capable of testing the wall static pressure of a thin-walled workpiece with temporary measure demands or a thin-walled workpiece with the limited normal space of the wall. The device is simple in structure, convenient to process and high in measuring precision, has a low requirement on space, and is suitable for testing on the wall static pressure of the thin-walled workpiece with the limited normal space of the wall. The device further can replace a structural form combining a wall test bench and a threaded connected testing mouthpiece, so that the workload for preserving or further processing a wall test bench of the thin-walled workpiece is alleviated, and the weight of the workpiece is reduced.
Description
Technical field
The utility model relates to the structural design field that wall static pressure is measured, particularly a kind of welded type thin-wall part wall static pressure proving installation.
Background technology
Wall static pressure measurement is a kind of more common fluid property parameter collection means, widespread use in the research in each field, test.Common metering system is wall perforate pressure, surveys near the static pressure of wall and replaces measuring the mobile static pressure on wall.In reseach of engine process, also often need to collect the wall static pressure of fluid, for performance evaluation, checking provide foundation.
At present, the wall static pressure of engine runner face in the following several ways: one, complete machine part or isobaric subscale test part.At the reserved test bench of thin-walled surface or repair welding test bench, be processed into threaded hole and connect mouth with screw connected test and is connected, employing sealing gasket seals.Two, non-isobaric subscale test part.This testpieces need not be considered weight issue, and wall thickness is enough, can directly process instrument connection and threaded hole, is threaded with lead-in wire, also can thread mill drilling connects mouth with screw connected test and is connected.Both of these case requires fluid wall to have certain radial space between lead-in wire connects.And the first situation has increased body weight, and manufacturability is poor.
Utility model content
The purpose of this utility model is to have the thin-wall part of interim measurement demand or the thin-wall part wall static pressure of wall normal direction limited space system measurement problem in order to solve, and spy provides a kind of welded type thin-wall part wall static pressure proving installation.
The utility model provides a kind of welded type thin-wall part wall static pressure proving installation, it is characterized in that: described welded type thin-wall part wall static pressure proving installation, comprises test bench main body 1, sealant layer 3, fairlead 4;
Wherein: test bench main body 1 is with the instrument connection of vertical direction and the fairlead of horizontal direction, two holes connect, between test bench main body 1 and thin-wall part 2, bonding by sealant layer 3, and fairlead 4 is inserted in the hole of horizontal direction of test bench main body 1.
Described test bench main body 1 and thin-wall part 2 junctions, with annular groove.Annular groove, for filling with sealant, guarantees the Fluid Sealing at this place.
Described test bench main body 1 is one-piece construction, centered by top with porose disk-like structure.
Advantage of the present utility model:
Solved and there is the thin-wall part of interim measurement demand or the thin-wall part wall static pressure of wall normal direction limited space system measurement problem.Simple in structure, easy to process, little to space requirement, measuring accuracy is high, the wall static pressure that is applicable to the limited thin-wall part of engine wall space of planes is measured, thin-wall part for other situations, also can replace wall test bench to connect with screw connected test the version that mouth is combined, reduce work wall test bench was reserved, added to thin-wall part workload, weight.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is welded type thin-wall part wall static pressure proving installation cut-open view;
Fig. 2 is welded type thin-wall part wall static pressure proving installation upward view.
