D-312 automatic oil filter is a commonly used hydraulic product under Weiliang. After years of development, this filter meets the usage needs of customers. There are three specifications available for selection: 60 mesh, 100 mesh and 150 mesh. Most customers often choose the 60 mesh one. The selection should be made based on the actual needs of customers. Of course, there are other models to choose from. If you have requirements for model selection, you can contact us, and we will wholeheartedly provide you with thoughtful services.
The core feature of the D-312 automatic oil filter is to separate impurities and purify the medium, and prevent unwanted substances through specific structures or materials to ensure that the target fluid or gas reaches the expected purity.
1. Core functional features
Selective filtration: It can selectively block impurities of specific particle sizes, shapes or properties, such as solid particles, microorganisms, colloids, etc., while allowing the target medium to pass through.
Medium adaptability: It can adapt to different types of filtration objects, including liquids (water, oil, chemical solutions), gases (air, industrial waste gas) and solid mixtures (powder classification).
Efficiency controllability: The filtration efficiency can be adjusted by selecting filter materials with different precision (such as micron level, nanometer level) to meet different needs from coarse filtration to fine filtration.
2. Structural and performance features
Modular design: Most filters adopt replaceable filter element and filter bag structures, and there is no need to disassemble the entire equipment during replacement and maintenance, which is easy to operate.
Strong weather resistance: Filter materials and shells can be made of corrosion-resistant, high-temperature-resistant or high-pressure-resistant materials (such as stainless steel, polytetrafluoroethylene) to adapt to complex working conditions.
Pressure loss balance: High-quality filters will optimize the flow channel design, reduce the pressure loss during medium flow while ensuring the filtration effect, and reduce the system energy consumption.
3. Application scenario features
Wide versatility: It covers multiple fields such as industry (chemical industry, electronics, automobile manufacturing), people's livelihood (tap water purification, air purifiers), medical treatment (liquid medicine filtration, sterile air preparation).
High degree of customization: The filtration accuracy, flow rate, size and installation method can be adjusted according to specific scene needs, such as special filters designed for high-viscosity liquids.
The working principle of the filter is to use physical or chemical means to adsorb impurities while allowing the target medium to pass through, so as to realize medium purification.
D-312 automatic oil filterThe working process mainly revolves around the two key actions of "blocking impurities" and "allowing the medium to pass through", which can be divided into the following three core mechanisms:
1. Physical blocking mechanism (the most common)
This is the core principle of most filters, which blocks impurities through the physical structure of the filter material.
Surface filtration: There are tiny pores on the surface of the filter material, and the pore size is smaller than the impurity particle size. Impurities are blocked on the surface of the filter material, and the target medium (such as water, air) passes through the pores. It is commonly found in filter screens, filter bags, etc., such as the pre-filter of household water purifiers.
Deep filtration: The filter material has a complex three-dimensional porous structure inside (such as the gaps between sponges and activated carbon particles). Impurities will be intercepted layer by layer in the pores inside the filter material, which not only depends on the pore size, but also realizes interception through the collision and entanglement between impurities and the filter material.
2. Adsorption and separation mechanism
Some filters combine chemical or physical adsorption to enhance the removal of specific impurities.
Physical adsorption: Using the porous structure and surface tension of filter materials (such as activated carbon, zeolite) to adsorb impurities (such as odor molecules, pigments, heavy metal ions) on their own surface, so as to separate them from the medium.
Chemical adsorption: The filter material reacts chemically with impurities to convert soluble impurities into insoluble precipitates or harmless substances, and then intercept them through subsequent filtration. For example, the softening resin in some water purifiers will undergo ion exchange with calcium and magnesium ions in water to reduce the hardness of water.
3. Power drive and auxiliary mechanism
D-312 automatic oil filterrequires external power to promote the flow of the medium, and optimize the filtration efficiency through structural design.
Pressure difference drive: A pressure difference is formed on both sides of the filter (such as water pump pressurization, fan air extraction), forcing the target medium (liquid or gas) to overcome the resistance of the filter material and flow from the high-pressure side to the low-pressure side, and complete impurity separation during the process.
Gravity drive: Using the gravity of the medium itself to flow naturally, such as some simple precipitation filtration devices. Impurities settle because their density is greater than that of the medium, and the clear liquid overflows from the upper part.
