Detailed introduction of pneumatic components and what components are included

Overview of pneumatic components
Pneumatic components are components that perform work through the force generated by the pressure or expansion of gases, that is, components that convert the elastic energy of compressed air into kinetic energy. Such as cylinders, pneumatic motors, steam engines, etc. Pneumatic components are a form of power transmission and an energy conversion device that use gas pressure to transmit energy.

Technical characteristics of pneumatic components
advantage:
1. The pneumatic device has a simple structure, is lightweight, and is easy to install and maintain. The pressure level is low, so it is safe to use.
2. The working medium is inexhaustible air, and the air itself costs nothing.
3. It is very easy to adjust the output force and working speed.
4. High reliability and long service life.
5. Utilize the compressibility of air to store energy and achieve centralized air supply.
6. Full pneumatic control has the ability to be fireproof, explosion-proof and moisture-resistant.
7. Due to the small air flow loss, compressed air can be supplied centrally and transported over long distances.

shortcoming:
1. Due to the compressibility of air, the operating speed of the cylinder is easily affected by changes in load.
2. When the cylinder moves at low speed, the stability of the cylinder is not as good as that of the hydraulic cylinder because friction accounts for a larger proportion of thrust.

3. The output force of the cylinder is smaller than that of the hydraulic cylinder.




Composition of pneumatic components
Air source equipment: air compressor, aftercooler, air tank;
Air source treatment components: filter, dryer;
Pneumatic control components: pressure, direction, speed control valves;
Pneumatic actuators: cylinder, air motor, air claw;
Pneumatic auxiliary components: oil mist, silencer, pipe joints.






What do pneumatic components include?
1. Composition of triple parts
It consists of three parts: filter, pressure reducing valve and lubricator.
effect:
Filter: Filter harmful substances in compressed air to obtain a clean power source.
Pressure reducing valve: obtain stable pressure.
Oil mist: generates lubricating oil mist, reduces friction and increases service life.

1. Pressure reducing valve: adjusts the higher input pressure to the specified output pressure, and can keep the output pressure stable and is not affected by changes in air flow and fluctuations in air source pressure. Principle: If the handle is rotated clockwise, the pressure regulating spring is compressed, pushing the diaphragm and valve stem downward, the valve opens, and air pressure is output at the output port;at the same time, the output air pressure acts on the diaphragm through the feedback hole to generate upward thrust until When the thrust force is balanced with the spring force, the valve will have stable pressure output. If the output pressure exceeds the set value, the original balance is broken, and the diaphragm leaves the equilibrium position and deforms upward, causing the overflow valve to open and excess air to be discharged through the overflow port until the force on the diaphragm is balanced again.




Use the pressure reducing valve to turn the handle clockwise to adjust pressure and counterclockwise to relieve pressure. Note: The pressure reducing valve can be installed in any position. The direction of air flow is in the direction of the arrow and cannot be installed backwards. When using, lift the blue handle and rotate it;after adjusting the pressure, press the blue handle to lock it.



2. Filter: Filter out impurities, oil, moisture, etc. in the compressed air and store them in the filter to achieve the purpose of drying and cleaning the compressed air. Working principle: Compressed air flows in from the air inlet. The gas and the condensed water, oil and solid particles it carries are introduced into the filter cup through the cyclone blades. The cyclone blades cause the airflow to rotate in the tangential direction. Under the action of centrifugal force, the condensed water, oil and The solid particles are thrown to the wall of the filter cup and flow into the bottom to be deposited;then the compressed air enters the filter element and is further filtered, and the clean air is output from the air outlet.


Notice:


1) It should be installed vertically with the water cup facing downwards.
2) Manual drainage requires regular drainage;if it is difficult to observe the water level in the filter cup manually, automatic drainage can be selected.
3) If the filter element is found to be yellow or black, the filter element must be replaced in time.
4) The filter cannot filter gaseous water vapor.

3. Lubricator: There are many relatively sliding parts inside the pneumatic components that are sealed by sealing rings. In order to ensure good lubrication, a lubricator needs to be installed.
1) Reduce the friction between relatively moving parts.
2) Reduce the wear of sealing materials to prevent leakage.
3) Prevent corrosion of pipelines and metal parts and extend the service life of components.
Notice:
1) You can remove the oil cup and refuel directly or unscrew the oil filling plug (can be under pressure) to refuel;the adjusting screw (on the sight glass) can control the amount of oil to avoid excessive oil mist affecting the use of components.
2) When the lubricator is lower than the lowest oil line, pay attention to refueling, but be careful not to exceed the highest oil line.
