Portable and Fixed Off-line Filtration Units

Portable and Fixed Off-line Filtration Units


Hydraulic filtration units are an important component used in hydraulic systems. These filter contaminants and particles in the hydraulic fluid, allowing the system to operate more efficiently and reliably. Functionally, the cleanliness and quality of the oil used in hydraulic systems is very important. Dirty oil can cause wear and damage to valves, cylinders and other parts in the system.

Hydraulic filtration units typically come in different sizes and capacities. These are designed to purify the oil in the hydraulic system from particles of a certain micron size. Some filtration units can filter out even very small particles, thus helping to prevent wear and malfunctions in the system.

This type of filtration improves the performance of hydraulic systems, reduces maintenance requirements and extends component life. Additionally, it can reduce friction in the system and increase energy efficiency by maintaining the quality of hydraulic oil. As a result, hydraulic filtration units play a critical role in ensuring the reliability and longevity of hydraulic systems.

The Importance of Filtration in Hydraulic System

Filtration is of great importance in hydraulic systems because hydraulic systems are complex systems where the oil must flow correctly and the parts must constantly come into contact with the oil. Here are some main points explaining the importance of filtration in hydraulic systems:

1. **Parts Protection**: Parts in hydraulic systems often operate under very high pressure. Dirty oil can cause wear and erosion on the surfaces of these parts. By capturing particles and contaminants in the oil, filters extend the life of parts and prevent system malfunctions.

2. **Performance and Efficiency**: Clean oil enables hydraulic systems to operate more efficiently. Dirty oil can prevent valves, cylinders and other hydraulic components from functioning properly. Regular replacement or cleaning of filters improves system performance and ensures energy efficiency.

3. **Reliability**: Clean oil increases the reliability of hydraulic systems. Dirty oil can cause system malfunctions and unexpected shutdowns. Filters increase system reliability and prevent operating interruptions by removing contaminants from the system.

4. **Maintenance Costs**: Filters can reduce maintenance costs of hydraulic systems. Clean oil extends the life of parts of hydraulic systems and reduces maintenance requirements by reducing system malfunctions.

5. **Oil Life**: The mixing of contaminants and particles into the oil can shorten the life of the oil. Filters extend the life of the oil and extend oil change intervals by removing contaminants and particles in the oil.

For these reasons, it is important to ensure proper filtration and regular maintenance in hydraulic systems. This ensures long life of the systems and increases operating efficiency.

Portable and Fixed Off-line Filtration Units

Portable and fixed external (off-line) filtration units are two common filtration systems used to clean hydraulic oil and maintain its quality.

1. **Portable Filtration Units**: Mobile filtration units are portable and usually mounted on a vehicle or mounted on a wheeled chassis. These units are used to clean oil during maintenance and repair of hydraulic systems or during the operation of existing systems. They usually include a pump, one or more filters and, when necessary, a heat exchanger. Mobile units are particularly suitable for field maintenance or maintenance of portable equipment.

2. **Fixed External (Off-line) Filtration Units**: Fixed external filtration units are filtration systems that are installed permanently next to hydraulic systems or in connection with the system. These units are often located in fixed locations such as warehouses or workshops alongside hydraulic systems. Fixed external units can ensure continuous cleaning of hydraulic oil, reducing wear on parts in the system and improving system performance.

Both types of filtration units ensure regular cleaning of hydraulic oil, reducing wear on parts in the system, increasing system reliability and reducing maintenance costs. Which type is preferred may vary depending on factors such as intended use, system requirements and maintenance strategy.

Off-line filtration units are required in hydraulic and lubrication systems, in addition to the filters working in the system, as well as oil change and filling. It is not correct to transfer unused oil directly to the system without filtering, since it contains many particles. Oil of NAS 10, which is the cleaning class of the fresh oil barrels in general, must be filtered and transferred to the system.

Filtration units keep the cleanliness of the fluid working in the system at the highest level with filter elements produced with high technology. Thus, premature wear and tear of the system elements is prevented with the lowest level of contamination provided. In addition, the durability and life of the fluid used in the system is increased.

Thanks to a filter element with a sensitivity suitable for the system to be used in the filtration units, the negative effects of the settled particles in the fresh oil in the new barrel to be filled into the system are prevented. Since filtering with filtration units operates on a line separate from the main system, the filter element of the unit can be selected independently of the system. The fluid that is filtered off-line in this way can be filtered again, regardless of the operating time of the system, until it reaches the desired cleaning class.

The best results are obtained with filter elements produced in high technology. These filter elements, which are tested many times in test and analysis stands and have a flow rate of ß: 400 at 600 lt / min, have 99.97% particle retention. This value shows that the filter elements are absolute. When the filter elements, which are made of fiberglass, are examined under the microscope, it can be easily seen that they have a homogeneous structure and are produced from 7 separate layers with different features in the filter cross section. Fiberglass elements that provide absolute filtration up to 1, 3, 6, 10, 16, 25 µm can be used in filtration units. This change can be made very easily without the need for other equipment and without the need to stop the system to which it is connected.

Thanks to the filter elements (with water traps) that can be used in the filtration units that offer the best service, the free water in the fluid in the system can also be retained.

Water causes early wear, oxidation or sludge accumulation in the oil tank feeding the system over time. The filter element can keep the water ratio in the oil by pulling it down to the bottom values.
