Takeaways

• 😀 Regular maintenance of pneumatic equipment is essential for optimal performance and longevity.
• 😀 Always ensure safety equipment is worn according to the Standard Operating Procedures (SOP) when performing maintenance.
• 😀 Pneumatic equipment should be operated following the manual’s instructions, including proper handling of air compressors and pressure systems.
• 😀 Air compressors must be turned off and depressurized before maintenance to ensure safety during service.
• 😀 Periodic checks for water deposits and corrosion in air compressors should be performed by opening the drainage valve.
• 😀 Pneumatic pressure should be maintained between 4-6 bar in the service unit for proper function.
• 😀 Electrical supply must be verified, including AC power at 220v and DC power at 24v.
• 😀 Multimeter probes should be used to check for proper operation of electrical contacts, including ensuring that the buzzer sounds correctly in response to button presses.
• 😀 Solenoid valves should be tested by applying 24v DC to ensure proper airflow through the system.
• 😀 Double-acting cylinders should function correctly by directing pressurized air to either side to move the piston forward or backward.
• 😀 Pneumatic and electro-pneumatic circuits should be tested according to the wiring diagrams to ensure correct assembly and functioning of the system.

Q & A

What is the main focus of this lesson?

The lesson focuses on maintaining pneumatic equipment, with specific reference to maintenance procedures, safety precautions, and troubleshooting in industrial automation.

What are the key objectives for students after completing the lesson?

Students should understand how to maintain, service, and repair pneumatic systems in industrial automation, as well as follow the related work procedures and safety regulations.

What equipment and documents are needed for pneumatic equipment maintenance?

Students need to prepare an operation and service manual, maintenance and repair history documents, fault report cards, a multimeter, safety gear, and other necessary tools.

Why is it important to wear personal protective equipment (PPE) during maintenance?

PPE is crucial for ensuring the safety of workers by protecting them from potential hazards such as pressure, electrical faults, or injuries during maintenance activities.

What is the first step in the pneumatic equipment maintenance process?

The first step is to ensure the compressor is turned off and to release any pressurized air from the system.

What should be done with water and corrosion deposits in the compressor?

Water and corrosion deposits should be drained from the compressor by opening the drainage valve to ensure proper functioning of the system.

What is the correct air pressure range for the air service unit during maintenance?

The air pressure should be set between 4-6 bar, and the pressure should be locked to maintain this range during maintenance.

How is the solenoid valve tested during maintenance?

The solenoid valve is tested by applying 24V DC to check the airflow from the inlet to the outlet. If the valve is functioning correctly, air should flow when voltage is applied and stop when removed.

What role does the multimeter play in pneumatic equipment maintenance?

The multimeter is used to check electrical contacts such as those on limit switches, verifying whether they function correctly by measuring the continuity when buttons are pressed or released.

What should be done after completing the maintenance procedures?

After completing the maintenance, the work area should be cleaned, all tools should be returned according to procedures, and the maintenance activities should be documented in a written report.
