The high-pressure chamber of the festo air gripper DHWS-25-A is connected to the gas cylinder, while the low-pressure chamber is for gas output and leads to the usage system. The high-pressure gauge indicates the pressure of the stored gas in the cylinder. The outlet pressure of the low-pressure gauge can be controlled by the adjusting screw. When using the electric cylinder, first open the cylinder, then turn the low-pressure gauge pressure adjusting screw clockwise, compressing the main spring and transmitting the diaphragm, spring washer, and plunger to open the valve. In this way, the imported high-pressure gas enters the low-pressure chamber through the high-pressure chamber after throttling and decompression, and then goes to the working system through the outlet. By turning the adjusting screw, the height of the valve opening is changed, thereby adjusting the amount of high-pressure gas passing through to achieve the required pressure value. The pressure reducing valve is equipped with a safety valve. It is a device that protects the pressure reducing valve and makes it safe to use, and it is also a signal device for the failure of the pressure reducing valve. The medium valve introduces the composition structure of the German cylinder; this keeps the piston moving between the air cushions (even if the load changes, it can improve the action characteristics). The speed of the forward and return stroke can be adjusted. The air flow is the same in both directions. Single-acting cylinder, with one-way throttle valve Single-acting cylinder, with throttle valve Exhaust and intake flow control Throttle valve, bidirectional flow control The speed of the forward and return stroke can be adjusted. The flow in both directions can be set to different values. By controlling the flow in both directions to adjust the speed, this is usually applied to single-acting cylinders and small cylinders. The advantage is that it is very simple. Standard throttle valve, with QS Adjusted by the groove screw, can be rotated 360° after installation Standard throttle valve, with Q quick connector GRLA--QS--D metal Low flow– Quick connector Q GRLZ--QS--D metal Low flow, adjusted by the knurled screw, can be rotated 360° after installation GRLA-…-QS-…-RS-D metal Low flow, adjusted by the groove screw, can be rotated 360° after installation Rotary joint can rotate 360°GRXA-…-QS-…-D metal Low flow Q metal Low flow Adjusted by the knurled screw Electromagnetic valves to prevent electrochemical corrosion, when transporting and installing stainless steel and aluminum equipment and accessories, surface scratches should be avoided, construction should minimize contact with other metals, if necessary, plastic cloth can be wrapped around. For the equipment and accessories of the electromagnetic valve, soft pads should be added at the binding places to prevent damage to the equipment. Lifting should be carried out in order to prevent rework. When installing accessories, handle them lightly, and choose a reasonable lifting position for heavy objects. High-pressure jetting method This method does not require cutting off the pipe, and uses some auxiliary equipment of the pipe itself for descaling. The diameter of the nozzle used is very small, and the descaling effect of the water jet is the best close to the nozzle. Suitable for cleaning medium and small diameter pipes. Analysis of the high-pressure water jet principle and a series of experimental studies show that the jet angle between 35°~45°, the aperture between 1.4~1.6mm, the number of holes between 8~10 will produce greater impact force and thrust. In urban construction, water supply, heating projects, pipes with smaller nominal diameter can choose welded stop valves, balanced valves or plunger valves, such as smaller nominal diameter

1. Cylinders: Used to convert the energy of compressed air into mechanical energy to produce linear motion.
2. Pneumatic valves: Used to control the direction, speed, and pressure of airflow, regulating the operation of pneumatic systems.
3. Pneumatic motors: Devices that convert compressed air into rotary motion.
4. Air tubes and connectors: Used to connect various components in pneumatic systems and transmit air.
Yes, CKD pneumatic components require regular maintenance to ensure normal operation and extend service life. Key maintenance points include:
- Regularly check and replace seals and gaskets to prevent air leakage.
- Inspect and clean filters to ensure clean air quality.
- Lubricate moving parts to reduce wear and improve efficiency.
- Check air tubes and connectors to ensure secure and undamaged connections.
When selecting the appropriate CKD pneumatic components, consider the following factors:
Application requirements: Understand the specific working environment and tasks, such as load, speed, and stroke.
Air source conditions: Ensure that the pressure and flow of the air source meet the component’s requirements.
Installation space: Confirm available space and choose components of suitable size.
Environmental factors: Consider the temperature, humidity, and potential corrosiveness of the working environment to select suitable materials and designs.
Common pneumatic system faults include:
Air leakage: Causes efficiency decline; check seals, connections, and tubes, find leak points, and repair or replace.
Stuck cylinder piston: Possibly caused by dirt or insufficient lubrication; clean the piston and add lubricant.
Valve failure: Check electrical control signals, ensure smooth airflow, and verify if the valve itself is damaged.
Insufficient pressure: Inspect air source pressure, filters, and piping to ensure no blockage or leakage.
