The lift table gas spring is a component that can support, cushion, brake, adjust height and angle. The gas spring of the lifting table is mainly composed of piston rod, piston, sealing guide sleeve, packing, pressure cylinder and joint. The pressure cylinder is a closed chamber filled with inert gas or oil and gas mixture. The pressure in the chamber is several times or dozens of times of atmospheric pressure. When the air spring acts, the pressure difference on both sides of the piston is used to realize the movement of the piston rod. Gas springs have different structures and types to meet different requirements.
What are the characteristics of the lift table gas spring?
The lifting table gas spring is a kind of labor-saving lifting spring, which can be divided into self-locking gas spring and non-self-locking gas spring (such as the lifting support of car trunk and closet door). The structure of the gas spring is mainly composed of sleeve, piston and piston rod, etc. The sleeve is filled with high-pressure air or high-pressure nitrogen gas, and the pressure difference is generated due to the different areas at both ends of the piston, which drives the piston and piston rod to move and support people or heavy objects.
How to select the lift table gas spring?
There are four types of joints of compressed gas spring: single piece, single lug, double lug and universal ball joint, which are in turn single piece, single lug, double lug and universal ball joint. During the design, the matching joint type shall be selected according to the specific conditions of the installation site and the specifications of the gas spring. Universal ball head type is recommended. This kind of gas spring can automatically adjust the connection angle during the working process, thus eliminating the lateral force of the gas spring, and is especially suitable for occasions with high installation accuracy requirements. If the installation space is limited, an ear type can be used. This kind of gas spring has simple structure and small installation space, but it can not eliminate the lateral force generated by different shafts in the working process. Therefore, it is necessary to design another gas spring pin to connect it. In short, no matter what joint type is selected, it is necessary to ensure that the door (cover) can be opened and closed smoothly without interference and jamming after the gas spring is installed.
What is the principle and structure of the gas spring of the lifting table?
The working principle of the lift table gas spring is to use inert gas as the elastic medium (such as oil, transformer oil, turbine oil 50%) for sealing lubrication and pressure transmission of elastic elements, which is called gas spring. In fact, it is a variant of sleeve air spring. The characteristics and development of elastic sleeve air spring need to be further improved. It also has the general characteristics of air spring structure. The spring is composed of air cylinder, piston (rod), seal and external connector. High-pressure nitrogen or inert gas can form a cycle with the oil cylinder. The damping chamber and rodless chamber on the piston rod have two pressures, and the pressure area of the two chambers and the compressibility of the gas generate elastic force.
