How the cylinder works, let's find out today through a 3-d animation of its interior:
And today we're learning about the core of the aerodynamic technology -- the aerodynamic element: the cylinder。
Basic construction of the cylinder
So-called, aerodynamic components are elements that use compressed air as a power, driving the agency to move straight, swing and rotate。
And the implementation part of the above figure is a little bit colorful, so let's take the most common basic cylinder, see what's inside. Sir, please look
So the question is, if you look at the chart, can you see whether it's a single cylinder or a double cylinder
If there is a fog on the side of a small partner, we're going to do some gas tank classification before we go into detail。
Classification of cylinders
Single-acting cylinder:
Pistols only side of the gas supply, pressure boosters the piston to generate thrusts, springs or self-help returns。
It's like, even if you're a single dog, you can go to the pool. Because it'll bounce back to you。
Double-acting cylinder:
There's air pressure on both sides of the cylinder piston to achieve movement forward or backward。
So, another one becomes -- you're lucky to find your goddess, and now you can play badminton with her。
Buffering of the cylinder
But there's also a problem with the cylinder, if it doesn't use a buffer, when the piston moves to the terminal, especially with long- and fast-paced cylinders, the piston hits the lid with a great deal of kinetic energy, easily damaging parts and reducing the life of the cylinder。
Moreover, the noise caused by the shock is quite deadly. If a cylinder without a buffer is 70 db, then the whole plant will be up to 140 db, like a long-term jet runway。
This has reached the limit of human insufferability and suffering, and in the long run, your iq will be "unsufferable"...
How can they be addressed
Our designers designed a buffer for the cylinder. In the words of spring night's selling car: the pig hit the tree, you hit the pig。
Our product designer, in order to prevent the piston from hitting the tree, would rather let the piston hit the pig。
Hydraulic buffer
The first and simplest way to buffer the cylinder: to put a soft “pig” in front of the piston that is about to hit the tree (to install hydraulic buffers at the front end of the cylinder)。
It's a joke, and we're gonna say something serious
We take the example of the rbq series of hydraulic buffers, which use mineral oil as a medium to smooth the transition from high-speed light to low-speed heavy loads through unique anti-nico design。
Characteristics: the broad range of energy from small to large is not regulated to achieve optimal energy absorption。
Rubber buffer
And in order to be more compact at the plant, the designers came up with a way to put the pig in the cylinder。
That's the second way: rubber buffer. (piston poles set buffers on both ends)
Note:
1) the buffer capacity is static and small, mostly for small cylinders to prevent noise。
2) attention needs to be paid to the ageing of rubber leading to deformation and deformation。
Air buffer
And finally, the designers stopped designing the pig that produced the elephant, and they did it in a more subtle way, creating an invisible but still soft pig in the cylinder。
That's the third way: air buffer. (buffering is achieved by creating a closed gas chamber/buffer cavity on one side by co-activating buffers and seals during pistons movement
The gas in the buffer cavity can be discharged only through the buffer valve. When the buffer valve is open for hours, the inner cavity pressure rises rapidly, and the pressure is counterproductive to the piston, thus slowing it down until it stops。
Note:
1) by regulating the opening of the buffer valve, the buffer capacity is adjustable. The smaller the opening, the greater the buffer。
2) a buffer is achieved by using the back pressure at the time of the act of the cylinder. The gas tank's back is low. The buffer capacity will also be reduced. When used, care shall be taken to control the load rate and gas tank speed。
Magnetic switch
Speaking of which, we know how the cylinder moves. But there are rules for everything, and so is the gas tank movement. Are they all in position? Did you cross the border? Who's gonna supervise this
So now we're going to introduce you to the magnetic switch. It is the feedback signal that determines whether the cylinder is running, controls the corresponding electromagnetic valve to complete the switch。
Principle: the magnetic ring that moves with the piston approaches or leaves the switch, the springs in the switch are attracted or disconnected by magnetization and send a telecommunications signal。
Characteristics: as there is no need to set up control valves and frames at both ends of the cylinder process, and no need to set bumps at the end of the piston, user-friendliness, tight structure, high reliability, long life, low cost, high frequency of switch reaction time have gained extensive application。
Air tank lubrication
Also, let's say, lubrication, the purpose of which is to reduce the damage to the cylinder itself, to extend its useful life。
For oil lubricants:
Use of oil aerosols to mix lubricant into compressed air for transport to gas cylinders。
Non-oil lubricants:
Use only internal lubricant and no more use of aerosols for oil supply; avoid contamination of food, packaging of medicines by oil during transport, effects on the nature of certain industrial chemical paints, or effects on the accuracy of detection instruments。
Note:
Once oil lubricants have been used, their continued use is required. Once disabled, life expectancy drops sharply。
