Inject soul into the crusher – control system

September 24, 2023    Hawk

Equipment is just like humans. Without a “soul”, it is like a walking zombie. So what is a soul? Of course, it is thought! Of course, machines cannot have thoughts like humans, but it is still good to implant a system into it to control it at this time.

The control system of the crusher is usually a PLC (programmable logic controller) control system. The PLC control system is a digital electronic device that can automatically control various production processes.

So let’s take a look at what advantages make PLC (Programmable Logic Controller) control systems popular in industrial automation. Advantages:

  • Highly reliable: PLCs are designed to operate in industrial environments, so they have good immunity to interference and high fault tolerance.
  • Flexibility: PLC can be programmed as needed to meet various complex control needs.
  • Easy maintenance: PLC system fault diagnosis is convenient, and faults can be quickly located and repaired.
  • Efficient: PLC can handle a large number of input/output signals, thereby improving production efficiency.
  • Scalability: The functionality of the PLC can be expanded by adding modules.

However, everything cannot escape the law of two sides, and the PLC control system also has some shortcomings:

  • High initial costs: PLC hardware and software can be relatively expensive to purchase, install, and program.
  • Professional knowledge required: Programming and maintenance of PLC requires professional electrical and computer knowledge.
  • Updates can be difficult: If the PLC program needs to be updated or changed, downtime may be required, which may impact production.
  • Compatibility issues: PLCs from different manufacturers may have compatibility issues, which may limit the scalability and flexibility of the system.

Overall, the advantages of PLC control systems usually outweigh their disadvantages, which is why they are so popular in industrial automation.

PLC (Programmable Logic Controller) control systems are found in many different types of industrial equipment and processes, including but not limited to:

  1. Manufacturing equipment: such as assembly lines, machine tools, packaging machines, injection molding machines, etc.
  2. Process control: such as chemical industry, petroleum, food processing, pharmaceuticals, water treatment, etc.
  3. Building automation: such as elevator controls, HVAC (heating, ventilation, and air conditioning) systems, lighting controls, etc.
  4. Energy systems: such as electricity generation, transmission and distribution, renewable energy systems, etc.
  5. Transportation system: such as rail traffic control, traffic signal control, parking lot management, etc.
  6. Warehousing and logistics: such as automated warehouses, conveyor belt systems, loading and unloading equipment, etc.

The flexibility and reliability of PLC control systems make them ideal for these applications.

Failure of the crusher’s control system may cause the equipment to fail to work properly or degrade performance. Therefore, being able to detect and troubleshoot problems in a timely manner is a vital and necessary skill in the use of equipment. The following are some common fault diagnosis methods and repair steps:

How to diagnose fault?

If the crusher suddenly stops working, there may be a power issue. Check the power cord and power switch to make sure they are not damaged or disconnected.

If the crusher operates erratically or its performance decreases, it may be a problem with the parameter settings of the control system. Check the parameter settings of the PLC control system to ensure they are correct.

If some functions of the crusher do not work properly, it may be a module failure in the PLC control system. Use the diagnostic function of the PLC to check the status of each module.

How to repair it?

If it’s a power issue, you may need to replace the power cord or repair the power switch.

If it is a parameter setting problem, you can reset the parameters or restore them to factory settings.

If it is a module failure, the failed module may need to be replaced. If it is a software problem, the PLC’s software may need to be updated or reprogrammed.

Please note that repairing PLC control systems requires professional electrical and computer knowledge. If you’re not sure how to proceed, it’s best to call in a professional repairman to take care of it.
