How to ensure that pneumatic cylinders are not damaged during use

Pneumatic Cylinder is a commonly used transmission system in pneumatic control valves, with relatively simple daily maintenance and installation. However, if not careful during use, it can damage the cylinder, and even damage the cylinder. So what should be paid attention to when using it?

 

Before installing the bronchial tube and cylinder, be sure to check for debris in the pipeline and clean it thoroughly to prevent debris from entering the cylinder tube and causing damage or injury to the cylinder.

2. In the case of ultra-low temperature, measures should be taken to prevent moisture locking in the system software. Under high temperature standards, heat-resistant aluminum profile cylinder pipes that match should be selected and installed.

If the load changes during operation, a cylinder with sufficient output force should be selected.

4. Try to avoid side loading during operation, otherwise it may endanger the normal use of the cylinder.

If the cylinder is removed and not used for a long time, anti fouling covers can be added to the intake and exhaust pipes to prevent surface rust treatment.

Before use, the gas cylinder should be fully loaded during testing. Before starting work, adjust the buffer less and gradually increase it. The speed adjustment during the entire process should not be too fast to prevent damage to the cylinder kit and cylinder due to excessive impact.

 

What if you don't pay attention to these things while using and there are problems with the operation of automated equipment.

1. Fault diagnosis

Observation: Observe whether the cylinder moves slowly and at a uniform speed. Check the paired cylinders for consistent operation.

Test: First, remove the cylinder to drive the air pipe, trigger the corresponding action, and check if there is compressed air blowing out of the air pipe. If there is air, there is a problem with the cylinder; if there is no air, there is a problem with the solenoid valve.

2. Maintenance

After determining that the cylinder has a malfunction, it needs to be repaired. The commonly used maintenance tools include fine sandpaper of 1500 # or above, snap pliers, white oil (white solid grease for cylinders), and corresponding sealing rings.

After disassembling the cylinder, first determine the location of the fault and pull the cylinder rod by hand to feel if there is any jamming; If there is no blockage, block one side of the air hole with your hand and then pull the cylinder rod. If it cannot be moved back to its original position, it indicates a gas seal leak.

If the cylinder rod gets stuck, it is usually caused by a lack of lubrication or the accumulation of a large amount of sludge inside the cylinder. Remove the cylinder, clean it with oil or water, and wipe it with a cloth. If cleaning with water, be sure to dry and observe the cylinder rod. Are there scratches on the cylinder and wear on the sealing ring. If there are scratches, they need to be polished with fine sandpaper and the sealing ring needs to be replaced. Then add white oil as an internal lubricant and reassemble. After installation, first pull the cylinder back and forth several times with your hand to evenly distribute the white oil in the cylinder. Then, ventilate the two air nozzles separately to quickly move the cylinder several times and squeeze out excess grease from the other air nozzle.
