Vacuum bellows refers to the axisymmetric tubular shell, its bus is corrugated shape, has a certain flexibility, so it is also called flexible tube or flexible tube. Due to the characteristics of its geometric shape, the bellows can change the length of the bellows in the axial direction under the action of pressure, axial force, transverse force and bending moment. The length of bellows extends under the action of tensile force; The bellows become shorter under compression force. The bellows length or bendability is determined by the value and direction of the applied force, the performance parameters of the bellows and other factors. It and light tube (plate tube) in addition to a certain strength and stiffness, but also has a large compliance and high fatigue resistance, these properties make the bellows have a very wide range of applications.
Single wall vacuum bellows can be widely used in golf courses, sports fields and other light load conditions such as drainage, permeability; Interior decoration wire casing; Automobile wire casing; Prestressed cable casing; Air conditioner drain pipe, etc.
Double-wall bellows can be widely used in highway, slope, golf course and other heavy load conditions of drainage, pervious; Municipal sewage discharge; Communication, power supply cable bushing and other occasions.
Working temperature: -40ºC~+125ºC, short time up to +205ºC;
Structure: wavy inside and outside;
Color: black, other colors can be customized (according to the need to open);
Characteristics of vacuum bellows: good flexibility, anti-distortion, good bending performance, can withstand heavy loads; Acid resistance, lubricating oil, coolant, etc., shiny surface, friction resistance;
Bearing capacity: can bear the weight of foot, no breakage, no variation, can be quickly restored, and itself without any damage;
Application: Machinery manufacturing, electrical insulation protection, lighting equipment, automobile manufacturing, aviation equipment, subway, train, automation control and other industries;
