Hebei Hankai hydraulic oil seal manufacturers




The hub axle seal's primary function is to keep the axle lubricated. The lubricant, often a type of grease or oil, is crucial for reducing friction between moving parts. Without proper lubrication, the components can suffer from overheating and excessive wear, potentially leading to significant damage and costly repairs. Additionally, the seal prevents water and dirt from entering the axle assembly, which can cause rust and corrosion, further jeopardizing the integrity of the axle.
Protective relays are devices that monitor electrical parameters and detect abnormalities, such as overcurrent or overvoltage conditions. When a fault is detected, relays send signals to circuit breakers to trip and isolate the affected section. This quick response helps protect vital equipment and minimizes disruptions to the power supply.
