axial gaps. Nonrubbing seals, which range from simple gaptype seals to multistage labyrinths ( fig) are practically without friction and do not wear. They are, therefore, particularly suitable for highspeed and hightemperature operation. Bellows and membranes are used to seal components which have limited movement relative to each other.
Mechanical shaft seal types and sealing systems 28 Type G Rubber bellows seal with reduced seal face Rubber bellows seal like type B but with a narrow seal face. Due to the narrow seal face, the seal performs well in highviscosity and antifreeze liquids. Type G Type D Balanced Oring seal with spring on the atmospheric side Due to the balancing,
liquid film seal by injecting oil between stationary bushings at a pressure higher than the process pressure. A thermoplastic rubtolerant labyrinth seal and a gold babbitt coating on the breakdown bushings provide improved resistance to harsh sulfides and chlorides in process gases. The ISOSLEEVE cartridge seal offers: ROTOR SLEEVE
floating labyrinth seals of highquality fiberrein forced synthetic material which are floating in the seal carrier (Type 20) are used with Ebearings. This type of seal has various advantages to offer: – it is insensitive to radial displacement of the shaft, resulting for exam ple, from shaft bending or from lifting the rotor when taking out the shell.
May 27, 2004· A labyrinth seal is a noncontacting circumferential seal utilizing a tortured path for flow between the stationary and rotating parts. The design utilizes a series of pressure drops to reduce the leakage. The problem with these types of seals is that they do not seal in a "flooded" application.
There are a large variety of dry gas seal configurations, including single seals, tandem seals, and tandem seals with an intermediate labyrinth seal. Tandem seals with an intermediate labyrinth are generally used in natural gas applications due to the minimal leakage to atmosphere.
Oil seals – often called grease, fluid or dirt seals – close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. They also stop harmful contaminants from entering machinery, particularly in severe environments.
Sep 08, 2017· Seal Types: There are two different types of seal sections: 1. Labyrinth type protector: Labyrinth type seal uses the difference in specific gravity of the well fluid and the motor oil to keep them apart even though they are in direct contact. Labyrinthstyle protector creates a tortuous path of protection from well ﬂuids.
Product > Cassette Oil Seal > B Labyrinth Type Cassette Oil Seal for Wheel Hub 145*175*/ 1 Cassette oil seal / kassette oil seal is usually made of NBR The temperature is 80 C, the speed is 7m/s, and the pressure is
Isolator Labyrinth Oil Seal Roller Bearing Oil Seal Labyrinth seals for maximum bearing protection. Labyrinth seals are used by customer request in all its pumps to isolate the bearings from harmful contaminants while keeping bearing lubricated. Quality Policy Focusing on technology,persuing high quality,and implementing brand strategies.
The original Simmerring® is a premium quality radial shaft seal conforming to DIN 3760 and ISO 61941 with an elastomeric outer diameter. The Simmerring® can be used in numerous original equipment applications across a broad spectrum of market segments (, gearboxes, transmissions, axles, engines, and pumps).
Labyrinth metal seal. Metallic materials of GMN seal components series L/M guarantee highest resistance against coarse and fine contamination. Metallic materials are suitable for temperatures up to 200 °C. The L design is particularly suited for use with normal spray load for rotating shafts and hubs.
The oil seals consist of a stationary part, which is fitted in the housing, and a labyrinth ring that rotates with the shaft. The labyrinth ring is held in place by two hollow silicone rubber cords, which also help to prevent oil leakage .
A type of air and/or oil seal used around the mainshaft bearing in a gas turbine engine. The seal consists of a series of rotating blades that almost contact the seal land (the base of the seal). A small amount of air flows between the seal and the land and prevents oil from flowing past the seal.
Labyrinth Seals. The contactless design of labyrinth seals, which minimizes friction and shaft wear, makes them ideal for highperformance applications in the prevention of equipment contamination and to maintain optimal lubrication.
