The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. provides a detailed explanation of common faults and preventive measures for coal mine tunnel repair machines.

Faced with the harsh underground working environment, even the sturdy and durable Haoyun Heavy Industry coal mine tunnel repair machine inevitably encounters some challenges. Understanding these common technical challenges and their root causes can help us take more effective preventive and emergency measures to ensure the smooth operation of equipment. Here is an overview of several typical problems and solutions:

1. Power system malfunction

Performance: The engine has difficulty starting, runs unstably, and suddenly stalls.

Solution strategy:

Regularly check the fuel system to ensure unobstructed oil flow.

Clean or replace the air filter to maintain good air circulation.

Maintain the ignition system, such as spark plugs, high-voltage coils, etc.

2. Hydraulic system abnormality

Performance: Leakage, insufficient pressure.

Solution strategy:

Pay close attention to the quality of hydraulic oil and replace it regularly.

Find and repair the leakage point, replace worn seals.

Regularly clean the filter to avoid the accumulation of impurities.

3. Control system disorder

Performance: instruction lag, automatic shutdown.

Solution strategy:

Upgrade software to ensure the latest version.

Check the wiring to ensure good contact of the circuit board.

Clean the control panel to prevent dust and water damage.

4. Decreased cutting and excavation efficiency

Performance: tool passivation, gearbox wear.

Solution strategy:

Regularly inspect the cutting edge and replace or polish it in a timely manner.

Strengthen the lubrication of the reducer and regularly check the gear clearance.

5. Mechanical structural damage

Performance: Loose chain and broken support frame.

Solution strategy:

Adjust the tension of the chain to maintain suitability.

Regularly inspect the framework structure and promptly weld and repair any cracks found.
