Wiper oil seals, commonly referred to as lip seals or simply oil seals, are mechanical seals used to keep lubricants in and contaminants out of machinery. They are typically made from durable materials such as rubber or elastomers, designed to withstand high pressures and temperatures. The primary function of these seals is to maintain a barrier that prevents the escape of oil, while also preventing dirt, dust, and other contaminants from infiltrating the system.
By preventing lubricant loss, oil seals also contribute to energy efficiency. Leakage can lead to reduced lubrication, which increases friction and energy consumption, ultimately impacting the performance of the machine. Additionally, the ingress of contaminants can cause significant damage to internal components, leading to costly repairs and downtime.
When selecting the appropriate hydraulic piston oil seal, several factors should be considered to ensure optimal performance
4. Shaft seals These seals prevent fluid from leaking along the shaft of the pump. They play a vital role in protecting the pump from contamination and maintaining the hydraulic fluid’s integrity.
2. Back-up Rings These are used in conjunction with seals to provide additional support and prevent extrusion of the seals under high pressure. Back-up rings help extend the life of the seals by preventing wear and tear.
2. Quality of Materials High-quality seal kits made from durable materials, such as polyurethane or fluorocarbon, offer better performance and longevity compared to cheaper alternatives.
3. Application Conditions Consider the operating temperature, pressure, and the potential for exposure to contaminants. Selecting the right seal kit can significantly extend the lifespan of hydraulic cylinders.
