Germany Schnake-Hydraulik seals Schnake-Hydraulik model Schnake-Hydraulik price

Schnake-Hydraulik seals are the customary term for general seals; simply put, they are seals for lubricating oil. They are mechanical components used to seal grease (oil is the most common liquid substance in transmission systems, and also refers to general liquid substances), isolating the parts requiring lubrication in the transmission components from the output parts to prevent lubricating oil leakage. Seals used for static sealing and dynamic sealing (generally reciprocating motion) are called oil seals. The representative form of oil seals is the TC oil seal, which is a double-lip oil seal with a self-tightening spring fully covered by rubber. The oil seals commonly referred to are usually this type of tc skeleton oil seal.

Schnake-Hydraulik seal principle

Due to the oil film controlled by the oil seal lip between the oil seal and the shaft, this oil film has fluid lubrication characteristics. Under the action of liquid surface tension, the stiffness of the oil film causes the end of the oil film in contact with air to form a meniscus, preventing the leakage of the working medium and thereby achieving the sealing of the rotating shaft. The sealing capability of the oil seal depends on the thickness of the oil film on the sealing surface; if the thickness is too great, the oil seal will leak; if the thickness is too small, dry friction may occur, causing wear on the oil seal and the shaft; if there is no oil film between the sealing lip and the shaft, it is easy to cause heating and wear. Therefore, during installation, some oil must be applied to the sealing ring, and it must be ensured that the skeleton oil seal is perpendicular to the shaft centerline. If not perpendicular, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also lead to excessive wear of the sealing lip. During operation, it is ideal for a slight amount of lubricant in the housing to seep out to achieve the state of forming an oil film at the sealing surface.

Schnake-Hydraulik seal applications

Skeleton oil seals are widely used in industries such as aviation, automotive, motorcycles, railways, vehicles, ships, home appliances, and construction machinery. They are suitable for sealing rotary and reciprocating motions. They are installed in various heavy-duty engines, gearboxes, axles, ships, cylinders, and other parts. Their main function is to prevent the penetration of the sealed medium (gas, liquid) and the entry of external foreign matter into the body. Precautions: The pressure-bearing range of ordinary oil seals is very limited, generally 0.03 MPa. This pressure is generally formed by the height difference of the lubricating oil itself. If higher pressure needs to be sealed, high-pressure oil seals should be selected (generally capable of withstanding up to 1 MPa pressure) or other sealing forms should be chosen.

Schnake-Hydraulik seal failure causes

Failures of mechanical seals are generally only discovered after phenomena such as abnormal leakage, abnormal wear, and abnormal torque appear. The causes of failures can be roughly divided into the following four aspects: 1) Incorrect design and selection of the mechanical seal; 2) Poor quality of the mechanical seal; 3) The precision of the machine using or installing the mechanical seal does not meet the requirements; 4) Incorrect machine operation.
