It is the support rod, the principle: in a sealed space, add high-density liquid material, and then pumped off the air inside, add a piston-like thing outside, so that high-density liquid material in compression to produce energy.
Specifically as follows:
The gas and liquid as the working medium of an elastic element, by the pressure tube, piston, piston rod and a number of couplings, which is filled with high-pressure nitrogen, due to the piston is equipped with a hole in the interior of the piston, the piston at both ends of the gas pressure is equal to the piston cross-section of both sides of the different, one end of the connection with the rod and the other end does not have, the pressure of gas pressure to the small side of the cross-section of the pressure, the pressure to the Under the action of gas pressure, the pressure to the side with small cross-sectional area is generated, that is, the elasticity of the support rod, and the size of the elasticity can be set by setting different nitrogen pressures or different diameters of the piston rod.
Unlike mechanical springs, struts have a nearly linear elasticity curve. The coefficient of elasticity X of the standard struts is between 1.2 and 1.4, while other parameters can be defined flexibly according to the requirements and working conditions.
Reasons for the use of hydraulic:
1, hydraulic transmission of various components, according to the need for convenient and flexible to the arrangement.
2, light weight, small size, small motion inertia, fast response speed.
3, easy to manipulate and control, can realize a wide range of stepless speed regulation (speed range up to 2000:1).
4, can automatically realize the overload protection.
5, generally using mineral oil as a working medium, relative movement surface can be self-lubrication, long service life.
6, it is easy to realize linear motion.
7, it is easy to realize the automation of the machine, when the electro-hydraulic joint control, not only can realize a higher degree of automatic control process, but also can realize remote control.
Extended Information:
1, the support rod piston rod must be installed down position, not installed upside down, so as to reduce friction and ensure the best quality of damping and cushioning function.
2. For high-pressure products, it is strictly prohibited to dissect, fire baking, smashing touch, and shall not be used as a handrail. 3. Use of ambient temperature: -35 ℃ - +70 ℃. (Specific manufacturing 80 ℃)
4. In the work should not be tilted force or lateral force.
5. Decide the pivot point installation position is. Can accurately carry out the work of the guarantee, pneumatic rod (gas spring) piston rod must be installed downward position, not installed upside down, so as to reduce friction and ensure the best quality of damping and cushioning function. It must be installed in an accurate way, i.e. when closed, let it move over the central line of the structure, otherwise, it often automatically pushes the door open. First installed in the desired position after spraying and painting.
