How can the controllable gas spring prevent deformation?

How can the controllable gas spring prevent deformation?

As a commonly used gas spring, controllable gas spring is often used in car seats, sofa beds and other products. Its working temperature is 40-70 ℃ below zero, and its span is relatively large. Sometimes the controllable gas spring may be deformed due to some reasons, so the deformation of the controllable gas spring should be avoided. How to operate is described in detail below. During heat treatment, the shape of controllable gas spring will change. When heated, the temperature of each part of the gas spring is different, and the gas spring will deform when the force is uniform; When the temperature is constant, the gas spring will deform when heated evenly. Controllable gas spring During the heating process, we can change the placement measures of the controllable gas spring, so that the controllable gas spring can be vertically placed, or hung there, or vertically placed in the structure of the furnace, so that the controllable gas spring can be horizontally placed inside or in some devices; The deformation of gas spring is related to many convenient conditions. If the stability of quenching medium is changed, the deformation of controllable gas spring can be controlled. If the controllable gas spring is deformed, it will definitely have a great impact on the stability of the product. Therefore, preventive measures should be taken to prevent the appearance of controllable gas spring from changing, which can be operated from the above points. Precautions for the use of controllable gas spring: the equipment in use is strictly prohibited from baking and knocking, and the high-pressure gas of the copper door factory is sealed inside. It is forbidden to disassemble without the guidance of professional personnel to prevent accidents. Due to the sliding seal, it is forbidden to bump or attach paint, glue and other substances on the piston rod surface during the equipment or operation, otherwise the service life of the product will be affected.

How does the gas spring work?

How does the gas spring work?

Gas spring manufacturer: gas spring is an elastic element with gas and liquid as working medium. It is composed of a pressure pipe, a piston, a piston rod and several connecting pieces, and is filled with high-pressure nitrogen. Because there is a through hole on the piston, the gas pressure at both ends of the piston is equal, but the cross sectional areas on both sides of the piston are different. One end is connected with the piston rod, and the other end is not connected. Under the effect of gas pressure, the pressure to the side with small cross-sectional area, that is, the spring force of gas spring, can be set by different nitrogen pressure or different diameter. Unlike mechanical springs, gas springs have nearly linear elastic curves. The elastic coefficient x of the standard gas spring is between 1.2 and 1.4. Other parameters can be flexibly defined according to requirements and working conditions. Gas spring manufacturer: gas spring has light structure and large working stroke; Smooth movement, can play the role of shock absorption and cushioning; It has stable and almost constant characteristic line; Simple operation, safe and reliable. But the processing cost is high. Gas spring manufacturer Air spring manufacturer: according to the principle of sleeve air spring, we can know that the force of air spring at any stroke S is: F=pVA/v-As P-initial pressure in the cylinder; V - initial volume in the cylinder; A - Cross sectional area of piston rod. Gas spring manufacturer: from the surface, it is very simple to install gas spring on the bus door. In fact, the problem to be solved by the installation design is far from as simple as imagined. Installation information only needs door body (geometry, quality, material, etc.), hinge and opening α， However, there are up to 6 unknown installation information. According to the mathematical theory, in order to solve the six unknowns, it is necessary to solve the equations composed of six equations composed of the six unknowns. It can be seen that it is almost impossible for designers to solve the installation of gas springs in pure theoretical form. Therefore, from the engineering point of view, it is the key to solve the problem of gas spring installation and design to dig deeply into the installation information and simplify the complexity.

Working principle and precautions of gas spring

Working principle and precautions of gas spring

1. The gas spring is installed from bottom to top, which can reduce the inner wall friction, ensure good damping coefficient and maintain the buffering capacity. 2. The installation position of the support rod moves over the center line of the structure to avoid automatic door opening. 3. In order to prevent the gas inside the spring from overflowing, sealing is important, so the surface of the piston rod must not be damaged. It is forbidden to apply paint and chemicals on the piston rod. 4. The gas spring shall not be affected by tilt force or lateral force when working, and shall not be used as handrail. When the temperature of the gas spring is too high, the inferior gas spring may explode. 5. The air pressure inside the gas spring is high, belonging to high-pressure industrial products. The temperature should not be too high, nor should it collide. 6. The ambient temperature is 34~71. Some special gas springs can be used in an environment of 80. Too high temperature may cause damage or explosion. 7. The size should be reasonable, the strength should be appropriate, and the stroke size of the piston rod should have an allowance of 8mm.

Classification and characteristics of gas springs

Classification and characteristics of gas springs

Gas spring manufacturer: classification and characteristics of gas spring 1、 Free gas spring is a widely used gas spring, which mainly plays a supporting role and cannot stop automatically during the travel. The gas spring manufacturer tells you that free gas springs are widely used in automobile, textile machinery, printing equipment, office equipment, construction machinery and other industries. Free gas springs are widely used in automobile, construction machinery, printing machinery, textile equipment and other industries because of their light weight, stable operation, convenient operation and favorable price, or in alpine environment, acidic or alkaline environment. 2、 Self-locking gas spring is widely used in medical/therapeutic instruments. The gas spring can be stopped at any position in the travel with the help of some release mechanisms, and has a great locking force (up to 10000 N) after stopping. 3、 The damper widely used in automobiles and medical/therapeutic equipment is characterized by its resistance changing with the running speed. The gas spring manufacturer tells you that it can obviously buffer the speed of the connecting mechanism. The damper is mainly used for buffering. Its characteristic is that the force of the gas spring changes with the running speed. When the acting point of the force guiding the gas spring moves faster, the resistance of the spring will obviously increase, while when the acting point moves slower, Resistance is almost non-existent, and dampers are mainly used in washing machines, refrigerators and other industries.

Installation position and precautions of stainless steel gas spring

Installation position and precautions of stainless steel gas spring

1. The piston rod of the stainless steel gas spring must be installed downward and cannot be inverted to reduce friction and ensure good shock absorption quality and cushioning performance. 2. Determining the installation position of the fulcrum is the guarantee for the normal operation of the stainless steel gas spring. The gas spring must be installed in the correct way, that is, when it is closed, let it move on the center line of the structure, otherwise the gas spring will normally reset automatically. After selecting the installation position of the stainless steel gas spring, we will discuss the installation of the stainless steel gas spring. The following are relevant installation precautions. 1. If the joint direction needs to be adjusted, turn the cylinder block or piston rod clockwise. 2. Reasonable size and proper stress. When the bin door is closed, the remaining stroke of the piston rod is generally about 10mm. 3. Ambient temperature: - 30 ℃ -+80 ℃.
