Product Details Hydraulic Filters: Operation, Types and Importance Hydraulic systems are important engineering systems used to control fluid pressures and transmit energy. In these systems, hydraulic fluids are controlled by a series of valves and motors. However, contaminants in the fluid can negatively affect the proper operation of the systems. This is where the importance of hydraulic filters comes into play. How Hydraulic Filters Work Hydraulic filters are devices designed to separate contaminants from fluids used in hydraulic systems. They capture solid particles and other contaminants as they pass through the fluid. The basic working principle is that the fluid is passed through a filter and the cleaned fluid continues. Types of Hydraulic Filters Strainer Filters : These types of filters retain solid particles using a mesh or perforated surface. Different mesh sizes have the capacity to trap contaminants of different sizes. Spin-On Filters : These types of filters usually come in replaceable cartridges. It is more practical to replace the entire cartridge in case of contamination. Semi-Automatic Filters : These filters allow the liquid to be forced through the filter under pressure. This allows the filtration process to be automated. Pressure Line Filters: Cleans the oil leaving the pump and entering the system. Return Line Filters: Cleans the oil returning from the hydraulic motor. Tank Filters: Cleans the oil in the hydraulic tank. Bypass Filters: Filters that are activated in case of excessive pressure and protect the system. Intake Filters: Cleans the air and contaminants entering the hydraulic tank. Importance of Hydraulic Filters Regular maintenance and replacement of hydraulic filters ensures the longevity of a hydraulic system. Failure to control contaminants can compromise the function of valves and other hydraulic components, or even lead to damage. Maintenance and Replacement of Hydraulic Filters It is important to check and replace filters at regular intervals. It is recommended that each type of filter be replaced at a specific time or cycle interval. This is key to maintaining the effectiveness of the filters and the health of your hydraulic system. Conclusion Hydraulic filters are a fundamental part of hydraulic systems and are critical to ensuring proper system operation. Choosing the right type of filter, along with regular maintenance and replacement, will ensure the longevity of a hydraulic system.
Hydraulic filters are mostly used in industrial and construction machinery areas, they have a wide range of products. Hydraulic filters are divided into different classes. Atomic type filter: This application is tightened by turning and attaching to the opposite mechanism with the help of a screw thread. Only the mouth of the atomic type filters is open and the oil circulation enters the system from the mouth and goes out from the mouth again after the filtration function is completed. Its outer surface is designed to handle the pressure in the system. Element type filter: These filters are placed inside the hydraulic system chamber, the lower surface contacts the system base, and the upper part is compressed with the cover thanks to the gasket it has and prevents oil leakage. Element type hydraulic filters are also divided into groups according to their types. Paper filter , wire filter , microglass, wire paper element filters serve the same function as atom type filters in the system, the difference between them is that since the chamber of the element type is fixed, the internal element is constantly changed, the chamber remains fixed. Since atom types have a chamber logic, there is no need for a chamber in the area where it is installed. One of the important reasons for the problems that occur in hydraulic systems is the wear and damage caused by dirty particles in the hydraulic fluid and lubrication oil. Hydraulic oil enters the gaps and performs the lubrication and sealing function. Dirty particles enter the gaps and cause wear, so the hydraulic system elements cannot perform their functions and the problem occurs. Liquids, solid particles and gases contaminate hydraulic oil. LIQUID PARTICLES: Liquids consisting of a mixture of water and different oils. SOLID PARTICLES: Sand-paint-rust-sawdust-gasket waste. Features that a quality hydraulic filter should have: Being resistant to pressure differences that may occur Filtering power for all cleaning degree classes Sufficient holding volume Long life
