To achieve a detailed and thorough revision of this passage into a 2000-word technical analysis on கொக்குtravel system diagnostics, I’ll expand on key elements, adding detailed explanations of fault causes, diagnostic tests, and troubleshooting methods for கொக்குmotor and control handle issues. Here’s an outline of how I would proceed with the extended draft:
1. Introduction to Crane Travel Systems
Overview of mechanical and hydraulic components in கொக்குtravel systems.
Importance of diagnostic approaches inகொக்குmaintenance for safety and performance.
2. Mechanical Components in Crane Travel Systems
Detailed mechanical alignment checks:
Why alignment of tracks, wheels, and rollers is essential for smooth operation.
Step-by-step alignment testing techniques, ensuring proper parallelism of tracks, alignment of centerlines across the drive wheel, guide wheel, carrier rollers, and load rollers.
Veering Diagnosis Based on Motion Type:
Explanation of why certain alignment issues cause veering in both forward and reverse, while others only affect one direction.
Procedures for diagnosing veering-specific faults.
3. Motor-Related Faults in Crane Travel
Internal Leakage in Hydraulic Motors:
Detailed look at hydraulic motor operation, specifically the impact of internal leakage.
Causes and symptoms of excessive internal leakage and its effect on volumetric efficiency.
Diagnostic steps for identifying and confirming motor faults, including drain port testing and interpreting oil flow results.
Verification of Motor Condition:
Discuss how specific speed variations between motors influenceகொக்குdirection.
Detailed explanation of how slow seepage from the drain port confirms motor functionality.
4. Control Handle Fault Diagnosis
Understanding the Role of the Control Handle:
Explain the function of the control handle in regulating main valve pilot pressure and overall hydraulic flow.
Discussion on how pilot pressure drops due to valve leakage impact கொக்குmotion.
Testing Valve Internal Leakage:
Expanded troubleshooting techniques, such as pressure testing for pilot lines and testing valve spools.
Verification via Oil Outlet Swap:
Comprehensive breakdown of the swap test method, outlining potential results and what each result indicates regarding handle or valve health.
