Troubleshooting Electrical Problems in the Fintec 1107 Jaw Crusher

[MikePhua]

Jaw crushers, such as the Fintec 1107, play a vital role in the mining and construction industries, where they are used for crushing large rocks into smaller, manageable pieces. These crushers are known for their robust design and high productivity, but like any heavy machinery, they are not immune to electrical issues. Addressing electrical problems promptly ensures the continued functionality and longevity of the equipment.
In this article, we will explore common electrical issues faced by Fintec 1107 Jaw Crusher users, how to diagnose them, and the best approaches to fix them.
Understanding the Fintec 1107 Jaw Crusher
The Fintec 1107 Jaw Crusher is a mobile unit designed for crushing hard materials such as rock, limestone, and concrete. It operates through a powerful electric motor that drives the jaw mechanism, feeding material into the crushing chamber where it is broken down by hydraulic pressure. The machine uses a conveyor system to transport crushed material out of the chamber.
The electrical system of the Fintec 1107 powers several critical components:

• Electric Motor: Provides the necessary power to the jaw mechanism and other machinery parts.
  
• Control Panel: Allows the operator to monitor and control the crusher's operations.
  
• Sensors and Switches: Ensure safety, efficiency, and proper machine performance.
  
• Hydraulic Systems: Controlled by the electrical system for the operation of various hydraulic components.
  

When any part of this electrical system fails, it can halt production, cause safety risks, or lead to costly repairs.
Common Electrical Problems in the Fintec 1107 Jaw Crusher
1. Power Supply Issues
One of the most frequent electrical issues in the Fintec 1107 Jaw Crusher involves interruptions or failures in the power supply. Without consistent and adequate electrical power, the machine cannot function as intended.
Possible Causes:

• Faulty Power Cable: Wear and tear on the power cable, especially when subjected to harsh working conditions, can cause short circuits or complete loss of power.
  
• Blown Fuses: Fuses protect the electrical system from damage due to overloads. A blown fuse can interrupt power to the motor or other components.
  
• Tripped Circuit Breakers: If the electrical circuit experiences an overload or short, the breaker may trip to prevent damage, cutting off power to the system.
  

Solution:

• Inspect the power cables for any visible signs of wear or damage and replace if necessary.
  
• Check and replace any blown fuses.
  
• Reset any tripped circuit breakers and ensure that the system is not overloaded.
  

2. Motor Malfunctions
The electric motor in the Fintec 1107 is responsible for driving the crusher's jaw mechanism. If the motor is not functioning properly, the entire crushing process can come to a halt.
Possible Causes:

• Burnt Motor Windings: Overheating or overloading the motor can cause the windings to burn out, leading to motor failure.
  
• Worn Bearings: The motor’s bearings allow the rotor to spin freely. Worn or damaged bearings can cause the motor to seize or operate inefficiently.
  
• Electrical Connection Failures: Loose or corroded connections can prevent the motor from receiving the required voltage.
  

Solution:

• Check the motor’s thermal protection system to ensure it has not overheated. If the motor is damaged, replacement may be necessary.
  
• Inspect the motor bearings for wear and replace them if needed.
  
• Clean and tighten any loose electrical connections to ensure proper power supply.
  

3. Control Panel Errors
The control panel allows operators to monitor and manage the crusher’s performance. Electrical malfunctions in the control panel can make it difficult to operate the machine properly.
Possible Causes:

• Faulty Sensors: Sensors in the control panel monitor various machine parameters such as pressure, temperature, and motor speed. If any of these sensors fail, the operator may receive inaccurate readings.
  
• Damaged Wiring or Connectors: Corroded or broken wiring can cause communication issues between the control panel and the machine’s components.
  
• Software Glitches: In some cases, software issues can cause the control panel to display error messages or fail to respond to commands.
  

Solution:

• Inspect the sensors for damage or wear and replace them if necessary.
  
• Check the wiring and connectors for any visible damage or corrosion. Clean or replace any affected parts.
  
• Reboot the control panel and update its software to ensure it is operating correctly.
  

4. Hydraulic System Electrical Problems
The hydraulic system in the Fintec 1107 is controlled by the electrical system, which powers various pumps, valves, and actuators. If the hydraulic system is not functioning properly, it can affect the crusher's performance.
Possible Causes:

• Faulty Solenoid Valves: These valves are electrically operated and control the flow of hydraulic fluid. If they fail, the hydraulic system may not work as intended.
  
• Damaged Hydraulic Pumps: If the hydraulic pump fails, the system may lose pressure, leading to poor performance of the crusher’s jaw mechanism.
  
• Electrical Power Loss to Hydraulic Components: Any interruption in the power supply to the hydraulic components can stop them from operating.
  

Solution:

• Check the solenoid valves and replace them if they are not functioning.
  
• Inspect the hydraulic pump for leaks or damage, and replace if necessary.
  
• Ensure that the hydraulic system is receiving consistent power from the electrical system.
  

5. Overheating and Electrical Shortages
Overheating is a common issue for heavy machinery like the Fintec 1107 Jaw Crusher, especially when running continuously or in extreme conditions. Overheating can lead to electrical failures, such as short circuits, which may damage sensitive components.
Possible Causes:

• Poor Ventilation: The crusher’s electrical components need proper airflow to dissipate heat. Blocked vents or dirty components can cause overheating.
  
• Excessive Load on the Electrical System: If the machine is overworked, the electrical system may become overloaded, leading to overheating and potential short-circuiting.
  

Solution:

• Clean and inspect ventilation openings to ensure proper airflow around electrical components.
  
• Monitor the load placed on the crusher and reduce it if necessary to prevent overloading.
  

Preventive Maintenance Tips for the Fintec 1107
Maintaining the electrical system in the Fintec 1107 Jaw Crusher is crucial to preventing breakdowns. Regular inspections and timely repairs can extend the lifespan of the equipment and ensure smooth operations. Here are a few maintenance tips:

• Regularly Check Electrical Connections: Inspect wires and connectors for signs of wear or corrosion. Clean and replace them as needed.
  
• Clean and Maintain the Control Panel: Ensure that the control panel is free of dust, dirt, and debris. Periodically recalibrate sensors to ensure accurate readings.
  
• Monitor Hydraulic Systems: Check the hydraulic fluid levels and condition regularly. Ensure the solenoid valves and hydraulic pumps are functioning properly.
  
• Test the Motor and Power Supply: Routinely check the electric motor, power cables, and fuses for any faults. Maintain the electrical system to avoid short circuits or power interruptions.
  
• Temperature Management: Ensure that the machine is operated within the recommended temperature range. Keep cooling systems clean and functional.
  

Conclusion
The Fintec 1107 Jaw Crusher is a powerful and reliable machine, but like any piece of heavy machinery, it can encounter electrical issues that hinder its performance. Understanding the common electrical problems, from power supply failures to motor malfunctions, is key to diagnosing and solving these issues efficiently. Regular maintenance and prompt troubleshooting can ensure that your Fintec 1107 operates at its full potential, minimizing downtime and maximizing productivity.
