- One of the key benefits of using oil seals is their ability to enhance the efficiency and longevity of machinery. By preventing oil leaks, seals help reduce energy consumption and maintenance costs. They also play a crucial role in preventing contaminants from entering the machinery, which can cause wear and tear on components and reduce the overall efficiency of the equipment.
MECHANICAL SEAL
Aluminum alloys and resin (materials with a large difference between the linear expansion coefficients) demand sufficient consideration (as there is a risk of failure due to the increased clearance with the oil seal at high temperatures).
Excellent heat resistance and oil
An oil seal has two tasks: Keeping the lubricant in and keeping dirt and contaminants out of rotating components. This separation must be accomplished between surfaces in relative motion, usually a shaft or bearing inner ring and a housing. With correct installation, oil seals can also prevent seal leakage and maintain the lubricity of a bearing to ensure that the rotary shaft and its bearings remain fully functional.
Make sure the fuel-pipe connections are clean. Unplug them and reconnect to the pump.
