Bellows rubber seal ring, bellows is originally used to isolate parts, usually can adapt to the shaft and radial movement of the seal.Xiamen better silicone sealing ring tells you that it can be used as a protective cover specially designed to isolate dust and dust from the machine;Used as auxiliary sealing ring in mechanical end face sealing;In the mixer, pump, compressor, mixer and other machinery and equipment to replace the stuffing box used as the main sealing ring.In the latter type, it is a simple form of mechanical end seal., bellows is originally used to isolate parts, usually can adapt to the shaft and radial movement of the seal.Xiamen beiteng sealing ring tells you that it can be used as a protective cover specially designed to isolate dust and dust from the machine;Used as auxiliary sealing ring in mechanical end face sealing;In the mixer, pump, compressor, mixer and other machinery and equipment to replace the stuffing box used as the main sealing ring.In the latter type, it is a simple form of mechanical end seal.
Rubber bellows is a special purpose pipe fittings, also known as telescopic hose.According to the usage of the rubber bellows can be divided into: aspiration with a rubber bellows, exhaust with a rubber bellows, protection to use rubber bellows, flame retardant rubber bellows, convulsions with a rubber bellows, etc., can also be made into steam hose, water hose pipe and other special purpose, at the time of selection to choose according to the actual requirements, if you don't know which need to use rubber bellows, can be used by your description or ask us to help you choose the suitable rubber bellows.
And the material of rubber bellows sealing ring (shown in figure 1 is the structure diagram of mechanical corrugated sealing ring), can be rubber sealing ring material or nylon material, or metal as sealing material.Rubber bellows for push-ring (end face) seals, usually with one or more metal springs to compensate for fatigue.Metal bellows are spring action, and, can be formed by rolling or welding.The welded bellows rubber sealing ring is a kind of expensive, to its structure is more solid, can give more accurate control of the working characteristics, and can be used in high temperature working environment.Multi-layer welding structure is adopted instead of single welding structure, which can further provide the performance of sealing effect, so as to better adapt to the high-pressure working environment.
Rubber bellows advantages: excellent flexibility, than the general rubber hose has a smaller bending radius, the inner rubber layer using high-quality heat-resistant and corrosion resistant rubber, dedicated to chemical gas, hot gas, dust and smoke exhaust operations, but also can be used for the media containing solid particles;Rubber bellows in general polyester, thermoplastic or special PVC duct has better aging resistance, wear resistance.Rubber bellows can also do fire retardant treatment, so that it is more safe and reliable in conveying high temperature media, spiral steel wire frame rubber hose is the ideal choice of modern industrial chemical gas, hot gas, dust and smoke exhaust operation.
Product structure: composed of wear-resisting and aging resistant inner rubber layer, fabric reinforcement layer, middle spiral steel wire skeleton layer and aging resistant outer rubber layer.
Use of rubber bellows:
Product usage: it is often used in the steeling furnace, coal mine, tunnel, subway project, underground part of the glass factory to carry on the pressure type guiding ventilation, as well as the purification equipment suction dust, waste gas, ash debris and so on.But it's not like you can't make a carbon nine hose.
Rubber bellows working pressure: generally, the working condition is not higher than 4bar in the low pressure environment, special circumstances will need to bear a certain negative pressure, that is, vacuum.
Product specification: dn32-dn2000
Product wall thickness :3-8mm
Service temperature: -45 degrees -220 degrees
Joint connection: flanged, fast joint, high pressure by ren, can also use special joint made of high temperature steam hose.
