Hydraulic Oil Filter Element
Most industrial equipment runs with the help of hydraulic oil and contamination free oil is a must for their optimum performance. Dust in the system can cause breakdown and failure, which can cause a lot of damage to equipment and also reduce product quality. Filter elements are needed in such conditions to capture those unwanted dust particles and remove them before they enter the system. They are most important to capture dirt from contaminated fluid and eliminate it through which only clean oil can pass into the system. It is always best to use filter assembly in all hydraulic systems to protect them from unwanted breakdown.
Functioning of Hydraulic Filter
The prime working principle of any hydraulic element is to provide safety by removing unwanted dirt in the system. Their placement in the system is dependent on the type of fluid used, type of dust present, working pressure, and temperature.
Types Of Hydraulic Filters Mostly Used in the Industries
- Suction Strainer
Fluid comes through a reservoir or tank containing large amounts of dust particles, which can cause damage to the pump and equipment if passed without any filtration. To capture those particles before they enter the system or pass through the pump suction line strainer is used. These elements are used at the starting point to capture higher dust particles. They can remove impurities up to 100 microns. They consist of stainless steel wire mesh for multiple-time cleaning and reusability.
- Pressure Line Filter
Filtered fluid comes through the suction element and enters the pump. Pump pressure makes fluid flow at higher pressure in the pipeline. To clean such high pressurized fluid pressure line filter is used in the hydraulic system. They help to purify oil at higher working pressure and clean it further before it enters the system. They are suitable enough to capture and eliminate dust up to 1 micron with the help of fiberglass media.
- Return Line Filter
Pressurized fluid passes into the system and gets back into the oil tank or reservoir. Before it dumps back into the tank it requires further cleaning for safety purposes. Return line filters are used just before the oil gets back into the tank for further cleaning. They help to purify dirty oil and make them filters before they get dumped back in the tank. Because they are placed before the tank when the oil returns back into it they are called return line filters.
Types of Filter Media Used
- Paper Media
As the name suggests, they are made of synthetic paper also known as cellulose.
Paper media are commonly used for oil flushing as they have a high dirt holding capacity.
One of the main key factors to use is because they are cheaper.
- Glass Fiber Media
For Absolute filtration, glass fiber is the first choice for any industry.
They help to remove small sized dust up to 1 micron.
- Wire Mesh Filter Media
They are made of stainless steel wires, which makes them resilient to work in harsh conditions.
The main advantage of these elements is their cleanability and reusability.
