Information
The emergence of gas springs further enhances the advantages of human labor-saving. The use of the spring is also wider. In the eyes of engineering and construction personnel, the gas spring is a good labor-saving tool. The types and styles of gas springs are different, but their application principles are the same, so let's learn about the reasonable use and installation precautions of gas springs!
1. What is the function of the gas spring?
Gas springs are industrial parts that play the functions of support, buffering, braking, height adjustment and angle adjustment. In construction machinery, they are mainly used in cylinder heads, car doors and other parts.
It is composed of cylinder, piston rod, piston, sealing guide sleeve, packing (inert gas or oil-air mixture), control elements in the cylinder and control elements outside the cylinder), joints, etc.
2. What is the structure of the gas spring? The working principle of the gas spring is to fill the airtight cylinder with inert gas or oil and gas mixture, so that the pressure in the cavity is increased to several times or dozens of times the atmospheric pressure, and the cross-sectional area of the piston rod is smaller than the cross-sectional area of the piston. The resulting pressure difference enables the movement of the piston rod.
3. What should be paid attention to when using gas springs?
1. The use environment of construction machinery is harsh, and the gas spring is required to be sealed, and dust and other debris must not enter the gas spring during use. In addition, do not damage or damage the surface of the gas spring piston rod with sharp tools, and do not apply paint or corrosive chemicals to the piston rod.
2. Add a certain margin (about 10mm) to the working stroke of the gas spring. There is an error in the installation process, which does not affect the life and performance of the gas spring.
3. Gas springs configured by construction machinery generally have a short service life due to the outdoor use environment, which needs to be considered in the design.
4. The ambient temperature range for gas springs is generally -35 to 60.
5. Gas springs cannot withstand lateral and oblique forces during work. The phenomenon of partial wear and the early failure of the gas spring should also be considered in the design.
6. Lightweight door structure without buckle device, after the door is closed, the connecting line between the fixed support point and the movable support point of the gas spring is designed to pass through the rotation center, and the elastic force of the gas spring closes the door firmly. Otherwise, the gas spring tends to push the door open; on the weighted door structure (machine cover), a locking device is provided.
7. When the gas spring is closed and working, there shall be no relative movement. Its continuous expansion and contraction should be controlled within the required range.
8. The door structure of construction machinery (such as machine cover) is generally heavy. When using gas springs, in order to avoid potential safety hazards caused by gas spring failures, please consider using gas springs with safety devices.
9. Do not use the gas spring as a limit device. Additional stopper is required. Stopping is usually done with a rubber head.
Gas springs are called support rods, gas rods, gas supports, etc. in our industry. From the current point of view, the use of support rods is very wide, from the furniture industry, automobile and motorcycle industry, machinery industry, electronics industry to transportation, fitness sports, medical equipment, but many factory staff are not unfamiliar with his installation method. One of the advantages of gas springs is the simplicity of installation.
1. The gas spring piston rod needs to be installed downwards and must not be turned over.
2. Determining the installation position of the fulcrum is the guarantee that the gas spring can work normally. Gas springs must be installed in the correct way.
3. The gas spring should not be subjected to tilting force or lateral force during the action. Cannot be used as a handrail.
4. In order to ensure the reliability of the seal, do not damage the surface of the piston rod. It is strictly forbidden to apply paints and chemicals, etc. to the piston rod. It is also not allowed to install the gas spring in the desired position before spraying or spraying.
5. The gas spring is a high-pressure product, and it is strictly forbidden to arbitrarily analyze, burn, and collide.
6. The piston rod of the gas spring is strictly prohibited to rotate. When it is necessary to adjust the direction of the joint, it can only be rotated to the right.
7. Use ambient temperature: -35-70. (Specific manufacture 80).
8. Install the connection point, the rotation is flexible, and there is no jamming phenomenon.
9. The size is reasonable, the strength is suitable, and the stroke size of the piston rod should have a margin of 8 mm.
The gas spring is an airtight product, so the quality of the gas spring must be seen from the appearance. The gas spring reported problems after 3 months of use. Such as air leakage and oil leakage and relatively serious rupture phenomena, selection force and production conditions, and recommended development and production experience. People who export and buy in bulk should pay more attention. Strengthen your own testing and choose product quality problems that are wrongly mass-produced.
The above introduces the reasonable use and installation precautions of gas springs. If you want to know more, please feel free to contact us!
