When performing a fracture analysis of a small release spring in a hydraulic pump, there are several steps that can be followed to determine the cause and determine the appropriate course of action. The following is an overview of the fracture analysis process: 1. Visual inspection: first visually inspect the broken spring to gather initial information. Look for any visible signs of fracture such as crack growth, irregularities or deformation. Note fracture surface characteristics, such as the appearance of the fracture zone, including regions of ductile, brittle, or mixed fracture characteristics. 2. Documentation: Document the condition of the broken spring through photos or sketches, making sure to capture different angles and close-up views. These records will be valuable for further analysis and reference. 3. Root Cause Analysis: Perform a root cause analysis to identify the underlying factors causing the break. This involves considering various potential causes such as material defects, design flaws, improper installation, overloading, fatigue, corrosion or excessive stress concentrations. 4. Material analysis: If possible, perform material analysis on the broken spring. This may involve laboratory testing, such as metallographic examination, to assess the microstructure and identify any material anomalies or defects. Chemical composition analysis can also be performed to ensure the spring material meets the required specifications. 90-R-075-KP-1-BC-80-R-4-S1-E-03-GBA-17-17-24 90R075KP1BC80R4S1E03GBA171724 90-R-075-KP-1-BC-80-S-3-S1-D-03-GBA-32-32-24 90R075KP1BC80S3S1D03GBA323224 90-R-075-KP-1-BC-80-S-3-S1-D-03-GBA-42-42-24 90R075KP1BC80S3S1D03GBA424224 90-R-075-KP-1-BC-80-S-3-S1-D-04-GBA-35-35-24 90R075KP1BC80S3S1D04GBA353524 90-R-075-KP-1-BC-80-S-4-C6-E-03-GBA-20-20-24 90R075KP1BC80S4C6E03GBA202024 90-R-075-KP-1-BC-80-S-4-C6-E-03-GBA-23-23-24 90R075KP1BC80S4C6E03GBA232324 90-R-075-KP-1-BC-80-S-4-C7-E-03-GBA-23-23-24 90R075KP1BC80S4C7E03GBA232324 90-R-075-KP-1-BC-80-S-4-S1-D-02-GBA-35-35-24 90R075KP1BC80S4S1D02GBA353524 90-R-075-KP-1-BC-80-S-4-S1-D-02-GBA-40-40-24 90R075KP1BC80S4S1D02GBA404024 90-R-075-KP-1-BC-80-S-4-S1-D-03-GBA-42-42-24 90R075KP1BC80S4S1D03GBA424224 90-R-075-KP-1-BC-81-S-3-S1-E-03-GBA-32-32-24 90R075KP1BC81S3S1E03GBA323224 90-R-075-KP-1-CD-60-L-3-S1-E-02-GBA-32-32-24 90R075KP1CD60L3S1E02GBA323224 90-R-075-KP-1-CD-60-L-3-S1-E-03-GBA-32-32-24 90R075KP1CD60L3S1E03GBA323224 90-R-075-KP-1-CD-60-P-3-C7-D-02-GBA-40-40-24 90R075KP1CD60P3C7D02GBA404024 90-R-075-KP-1-CD-60-P-3-C7-D-03-EBC-42-42-24 90R075KP1CD60P3C7D03EBC424224 90-R-075-KP-1-CD-60-P-3-C7-D-03-GBA-40-40-24 90R075KP1CD60P3C7D03GBA404024 90-R-075-KP-1-CD-60-P-4-C7-D-04-GBA-32-32-24 90R075KP1CD60P4C7D04GBA323224 90-R-075-KP-1-CD-60-R-3-S1-D-00-GBA-42-42-32 90R075KP1CD60R3S1D00GBA424232 90-R-075-KP-1-CD-60-R-3-S1-E-03-GBA-38-38-24 90R075KP1CD60R3S1E03GBA383824 90-R-075-KP-1-CD-60-R-4-C7-D-03-GBA-38-38-24-F060 90R075KP1CD60R4C7D03GBA383824F060 5.
