The role of hydraulic oil filter on oil mainly includes filtering impurities, extending the life of equipment, maintaining the system clean and so on. The quality of hydraulic oil directly affects the normal operation of the hydraulic system and the service life of the components, so the hydraulic oil filter plays a vital role in the system. Its specific functions are as follows:
1. Filter impurities
In the process of use and storage, hydraulic oil will inevitably be mixed with various impurities, such as mechanical impurities (including rust, casting sand, welding slag, iron filings, etc.), dust and seal fragments generated during the working process, metal powder, etc. If these impurities are not filtered effectively, they will circulate in the system and cause many problems. Through the filtration of the hydraulic oil filter, these solid particles and some soft pollutants are directly blocked and adsorbed, so as to keep the oil clean.
2. Extend the service life of the device
The components in the hydraulic system, especially some precision components such as hydraulic pumps, valves and cylinders, have high requirements for oil cleanliness. Contaminants can cause wear, blockage and even damage to these components, leading to system failure. Through effective filtration, the service life of these components can be significantly extended and failures due to contamination can be reduced. According to statistics, more than 75% of the failures in the hydraulic system are caused by hydraulic oil pollution.
3. Keep the system clean
Hydraulic oil is easy to oxidize and deteriorate under high temperature and pressure working environment, resulting in organic pollutants such as gum, asphaltene and carbon slag, which will affect the chemical stability and performance of the oil. By removing these harmful substances, the filter maintains the chemical stability of the oil and avoids system failures caused by oil deterioration.
4. Improve system efficiency
When the oil contains a large number of solid particles and dirt, it will increase the internal friction and pressure loss of the hydraulic system, resulting in increased heating and energy consumption of the system. By removing these contaminants, the filter reduces internal friction and improves the efficiency and response of the system.
