How to Choose Filter Element in Hydraulic Industry?
Introduction to Choosing Filter Elements in the Hydraulic Industry
Have you ever wondered what keeps a hydraulic system running smoothly? The answer lies largely within the hydraulic filter. Its core component, the filter element, plays a crucial role in maintaining the cleanliness and efficiency of the system. This article aims to guide you through the process of choosing the right filter element for your hydraulic machinery.
1. Understanding Hydraulic Filters
Hydraulic filters are designed to remove contaminants from hydraulic fluid, ensuring the system runs efficiently and the lifespan of the components is maximized. The filter element is the heart of the hydraulic filter. It is responsible for trapping and removing the contaminants from the fluid.
2. Filter Element is an indispensable Consumption in Hydraulic System.
Solid particle pollutant does great harm to hydraulic lubrication system. Each hydraulic and lubrication system has its own minimum requirements for the amount of contaminants in the oil-system target cleanliness. When the content of solid particles is lower than that of the system, the system can work well; When the content of solid particles is higher than the systematic target, the performance, reliability and service life of the system will be affected.
Because internal production hydraulic system will inevitably add a lot of solid particle pollution during operation, and because of outside invasion, hydraulic system must constantly remove solid particle contaminants so as to ensure the realization of target cleanliness.
The filter element is made of porous material. The solid particles in the system medium are trapped by surface interception and the adsorption of curved holes so as to achieve the purpose of purifying the medium. At the same time, the trapped solid particles may block the media channel of the filter element and make the pressure increase. When pressure reaches to extremity, the filter element cannot continue to work and needs to be replaced. Thus, the filter element is a consumable part of the system.
3. Steps to Select Alternative Filter Elements
1.) Check the current situation of medium cleanliness
The target cleanliness of the hydraulic and lubricating systems is given by the manufacturer of the equipment., users can know it from raw technical data of the equipment. When using the original filter element to maintain the cleanliness of the system, users can check whether original filter element can meet the system target cleanliness requirements by detection of contamination of system media. If the system cleanliness is qualified, the reasons need to be analyzed.
2.) Provide detailed information of the original filter element
To use a satisfactory alternative filter element, users must provide details of the original filter element and new or old original filter elements. In this way, it can help the manufacturer of alternative filter element to fully understand and master the performance parameters and dimension parameters of the original filter element, so as to obtain a satisfactory alternative filter element.
The quality, size, and structure can be easily judged by observation and trial assembly, but filtration accuracy, absorption capacity, initial pressure and other performance parameters can only be known after passing the corresponding inspection standards. Thus the users must ask the manufacturer of the replacement filter element to show the corresponding experimental results. Qualified users can also test the performance of the filter element by themselves or through a third party. Of course, users can also check the cleanliness of the system after the use of the alternative filter element to judge the quality of the alternative filter element.
A. Collecting data
Samples, original production drawing, Name of manufacturer (company), original product model, working principle for whole system, etc.
B. Know about the filter element
Installation, connection, sealing of product;
Where the product is used in the system;
Technical parameters(flow rate, working pressure, working temperature, working medium).
C. On-site mapping (differential pressure, filtration rate, etc.)
Types of Hydraulic Filters
There are several types of hydraulic filters, including suction filters, pressure filters, and return filters.
Each type has its own specific function and appropriate use within a hydraulic system.
What to Consider When Choosing a Hydraulic Filter Element
There are several factors you should consider when choosing a filter element.
1. Size and Filtration Rating
The size of the filter element should match the filter housing. The filtration rating refers to the smallest particle size the filter element can trap.
2. Material
The material of the filter element should be suitable for the type of hydraulic fluid used in your system.
3. Efficiency
The efficiency of the filter element refers to how well it can remove contaminants from the hydraulic fluid.
Detailed Guide to Choosing Hydraulic Filter Elements
With the basics out of the way, let's dive into how to choose the best hydraulic filter element for your system.
A. Consider the Type of Hydraulic System
Different hydraulic systems have different requirements.
For example, a high-pressure system may require a different filter element compared to a low-pressure system.
B. Understand the Operating Environment
The operating environment can greatly affect the choice of filter element.
1. Temperature (H3)
Extreme temperatures can affect the performance of your filter element. It's essential to choose an element that can withstand the operating temperature of your system.
2. Contamination Level (H3)
Areas with high contamination levels might require a filter element with a higher filtration rating.
C. Understand the Fluid Compatibility
The filter element material should be compatible with the hydraulic fluid used in your system. Incompatibility can lead to breakdown of the filter element, leading to system contamination.
D. Consider the Filter's Flow Rate and Pressure Drop
The filter's flow rate should match your system's requirements.
Additionally, consider the pressure drop across the filter; a significant pressure drop may indicate a clogged filter.
The Importance of Regular Maintenance and Replacement
Maintenance is key to the longevity and efficiency of your hydraulic system.
A. When to Replace a Hydraulic Filter Element
A filter element should be replaced when its efficiency decreases, usually signaled by an increase in pressure drop. A scheduled maintenance plan can help you stay on top of replacements.
B. Signs of a Damaged or Inefficient Filter
Signs that your filter may be damaged or inefficient include increased system noise, reduced system performance, and increased component wear.
Basic principles: try to bring samples (new or old) back to the company and make maps
Necessary basic factors: A. See basic structure clearly and make a general layout structure; B. Carefully measure and indicate dimensions including overall length, outside diameter, thread connection dimensions, sealing element dimensions, key surface roughness and fitting requirements)
Filter material: properties, accuracy, thickness of stressed skeleton, etc.
Mesh filter: material, pore size, flow direction of the filter medium, etc.
Proofread (A. If there is a lover at the surveying and mapping site, proofread each other; B. Proofread key points: assembly size, external connection, sealing, thread, key materials, structural form, product model)
FAQs
1. How often should I replace my hydraulic filter element?
This depends on your system's usage and the contamination level of the operating environment. However, it's generally recommended to check the filter regularly and replace it if necessary.
2. How can I tell if my filter element is damaged or inefficient?
Signs may include increased system noise, decreased performance, or increased component wear.
3. Is it necessary to match the filter element material with the hydraulic fluid?
Yes, it's essential. An incompatible material can degrade, leading to system contamination.
4. What's the impact of temperature on the filter element?
Extreme temperatures can affect the performance of your filter element. Therefore, choose a filter that can withstand your system's operating temperature.
5. Can a clogged filter damage my hydraulic system?
Yes, a clogged filter can increase the system's pressure, potentially leading to component damage and system failure.
Conclusion
Choosing the right filter element in the hydraulic industry is a vital process, one that requires understanding the basics of hydraulic filters, recognizing your system’s needs, and considering the operating environment.
