Hydraulic oil seals are sealing elements used to seal rotating shafts in mechanical equipment

My company specializes in providing four-column hydraulic seals and other products, our products are of reliable quality, high credibility, reasonable prices and widespread customer trust. The following introduces the seal mechanism principle of the four-column oil seal.

1. Overview: Hydraulic oil seals are sealing elements used to seal rotating shafts in mechanical equipment, and the cavity is essentially stationary.

2. Oil seal of the oil seal: static seal between the outer edge of the oil seal and the cavity, and at the same time ensure the reliable positioning of the outer edge of the oil seal between the cavities. The seal state between the seal lip and the shaft is dynamic when the shaft rotates. Sealed, static seal when shaft is at rest.

3. Hydraulic seal principle: In order to achieve the sealing effect, a layer of oil film must be formed between the shaft and the lip gap of the oil seal. Under the action of the liquid surface tension and the seal lip of the oil seal, a layer of oil film is formed to prevent leakage of the working medium. In order to realize the sealing of the rotating shaft, the oil film thickness is too large, and the oil seal leaks; if the thickness is too small, dry friction may occur, causing oil seal and shaft wear; if there is no oil film between the seal lip and shaft, heat and wear may occur easily. There are many influencing factors. For example: the smoothness of the sliding surface, the pressure distribution at the contact part, etc.
