Introduction
In fluid power systems, power and control is passed through a closed-loop pressurized liquid inside. Design elements that must be met
These changes in working conditions requirements. Detecting element meet the performance requirements carried out, to determine whether the design elements and practical test whether the element symbol
Combined requirements provided.
Test methods for hydraulic fittings
Warning. Some of the tests in this standard are dangerous and therefore must be strictly take all appropriate safety precautions during the test
Measures. For burst, fine spray (may penetrate the skin) hazardous energy release and expansion of the gas, etc. should be noted. In order to reduce energy
Dangerous release of pressure before the test specimen shall discharge the air inside. Test by trained and qualified personnel to operate and complete.
1 Scope
This standard specifies the types of metal fittings used in the hydraulic transmission, and port match the stud end, testing and performance of flanged pipe joints
Unified Approach evaluation. This standard does not apply to hydraulic GB/T 5861 covered by the quick-change test pipe joint.
The standard of the test is independent of each other, it is to follow the test file. Specific pilot project to be carried out and meet performance standards
Corresponding standard components.
Eligible for pipe joint determination, minimum number of specimens shall be specified in this standard test, but otherwise the relevant standard gauge fittings
Except in the case of a given user or manufacturer otherwise agreed.
