Many people will ask, what is a tcv oil seal?

The installation of hydraulic oil seal TCV high pressure oil seal on excavator, the characteristics of TCV oil
In fact, tcv oil seal is a mechanical part used to seal oil. It belongs to the inner skeleton and outer rubber type oil seal. It is a standard seal used for rotating shafts. It is vulcanized and connected by a metal skeleton and an elastic layer in the mold. It is mainly used in Low pressure, high speed rotation occasions. Such as the sealing of engines, vehicle transmission systems, gearboxes, motors, and gearboxes.

TCV type oil seal is a pressure-resistant oil seal that maintains rigidity while reducing the pressure area of ​​the lip, and is suitable for use in small diameter and medium pressure conditions. Its pressure resistance is below 0.5Mpa, and it is also a high-pressure skeleton oil seal and hydraulic oil seal. Pressure: ≤ 0.5Mpa, speed: ≤ 12 m/s.

FKM NBR is a double-lip skeleton oil seal with a spring. The upper part of the lip is made into a slanted wedge shape, and the upper part presses the shaft surface to seal the fluid. The auxiliary lip that is not connected to the spring is called a dust lip to prevent dust from entering.

The metal frame is used to maintain the fitting force when the oil seal is fixed in the cavity. The sealing lip is flexible and elastic, and is designed to remain stable under the influence of mechanical vibration and pressure fluctuations of the sealing fluid. It has a sealing effect and can maintain a stable contact state between the lip and the shaft surface.

The spring can greatly increase the pressing force of the sealing lip to the shaft and maintain the pressing force. The skeleton is like the steel bars in the concrete member, which acts as reinforcement and keeps the oil seal in shape and tension to the greatest possible extent.
Medium: engine oil, transmission oil, hydraulic oil, grease, emulsion
