End face expansion pneumatic sealing ring

The pneumatic flange, also known as the pneumatic flange by-nut / inflated by-nut, is a large-diameter, low-pressure, quick-installation and quick-disassembly pipe sealing connection component. It achieves sealing and connection by using an inflated rubber air tire to grip the steel pipe. Its main features include large misalignment compensation and tool-free disassembly and assembly.

The pneumatic clutch (also known as air bag/air expansion clutch) is a dry friction clutch that uses compressed air as power and relies on the expansion of rubber air tires to push the friction blocks to tightly grip the driven drum to transmit large torque. It also has the function of an elastic coupling. Industrial rubber clutch airbags, brake airbags, and brake tires are highly resilient, resistant to impact, and fatigue-resistant, and are used in industrial clutches, brakes, and pneumatic braking systems of transmission equipment.

The suction cup sealing strip of the shield machine is a ring-shaped or I-shaped foamed rubber strip installed on the vacuum suction cup surface of the assembly machine. Its function is to closely adhere to the inner arc of the pipe segment, form a sealed cavity, evacuate air to create negative pressure, and firmly hold concrete pipe segments weighing several tons to tens of tons, completing the grasping, transportation and assembly processes.

Dust Cover: The dust cover is also known as an extensible protective sleeve or a corrugated dust cover. It is a rubber protective plastic accessory, mainly made of high-quality rubber raw materials through vulcanization. It comes in various styles such as corrugated folding type, integrated cylindrical type, and closed type. The overall flexibility of the product is excellent, with good expansion and rebound effects, and it is resistant to pulling without cracking. Its main functions are dust prevention, waterproofing, oil and dirt prevention, sand prevention, rust prevention and corrosion prevention. It can isolate external dust and debris, rainwater impurities, avoiding long-term exposure of mechanical components to wear, rust, aging and jamming. The dust cover has excellent resistance to high and low temperatures, aging and friction. It has a large expansion stroke, flexible compression and folding, easy installation, and excellent sealing performance. It can freely expand and swing with the mechanical movement without affecting the normal operation of the equipment. It is widely used in engineering machinery, automotive parts, hydraulic piston rods, connecting rods, transmission shafts, shock absorbers, mechanical equipment connection parts, precision instruments, etc. It effectively reduces part wear, lowers equipment maintenance frequency, and extends the overall service life of mechanical components.

Fluorine rubber sealing ring: The fluorine rubber sealing ring is simply called the fluorine rubber sealing ring. It is currently the most advanced sealing product with extremely strong comprehensive performance in industrial sealing. It is made by high-temperature vulcanization of fluorine rubber material. The product has excellent high-temperature resistance, low-temperature resistance, acid and alkali resistance, oil resistance, solvent resistance, corrosion resistance, and its antioxidant and anti-aging ability far exceeds that of ordinary rubber materials. The fluorine rubber material can withstand a high temperature of up to 230℃, and can withstand a short-term maximum temperature of 300℃. It has good low-temperature toughness and is not prone to hardening or cracking. At the same time, it can resist the erosion of engine oil, hydraulic oil, chemical corrosive liquids, ozone and ultraviolet rays, and is not prone to deformation, swelling, aging or deterioration during long-term use. The sealing density is high, the rebound performance is excellent, the compression permanent deformation is small, it is wear-resistant and pressure-resistant, the sealing effect is stable, and the service life is more durable. Advantages: We have multiple molds that can meet most of the specifications and models in the market. Generally, there is no need for additional mold opening costs.
