In the processing of stainless steel sintered filter elements, the filtration accuracy should be accurate

The selection of stainless steel sintered filter element is also more important, and the filter material of the sintered mesh filter element is required to have sufficient corrosive properties in use. At the same time, if the stainless steel sintered filter element is made of metal, it is easy to rust, so additives need to be used. In the manufacturing industry, because the concept of pollution control and active preventive maintenance of equipment has not been widely promoted, the filtration technology of sintered mesh filter element has not been widely used. Some imported equipment that has arrived in my country does not pay enough attention to the filtration accuracy requirements of the equipment when selecting filter devices and filter elements, resulting in the cleanliness of oil products exceeding the standard soon after being put into operation, and the accident rate of equipment operation is high.

The filtration technology of stainless steel sintered filter element is aimed at the blood and oil products (including hydraulic oil, lubricating oil, cutting fluid, etc.) of machinery and equipment. Based on the requirements of system operation reliability, the concept and strategy of active preventive maintenance are adopted to fully understand the operation status of equipment. and element dynamic clearance, reasonably select the filtration accuracy and filtration area of the filter and stainless steel filter element, filter out the gap size particles, block the chain reaction of wear, and cooperate with regular monitoring to ensure the cleanliness of the oil and system, so as to achieve The purpose of reducing wear and tear, avoiding maintenance, extending the service life of components and equipment, and improving comprehensive economic benefits.

The filter element is not properly selected, it is not suitable for the current working environment when the filter element is selected, the filter element precision is too high, or the pressure exceeds the allowable high working pressure. It will also cause the filter element to be flattened. There are many customers who think that the selection of stainless steel sintered mesh filter elements and sintered felt filter elements will avoid this situation, but this is not the case. Although these two types of stainless steel sintered filter elements have their own pressure resistance, they exceed their own pressure resistance. There will also be a phenomenon of flattening. We should make appropriate adjustments according to the working pressure, such as adding a skeleton, so that the effect will be better.

Improper installation, the installation of the filter element should be accurate and stable, and the filtration work has already started before the filter element is fixed, so that the filter element is damaged.

I believe that through the above, everyone will pay more attention in the future to prevent the sintered mesh filter from being sucked flat. At the same time, the strength of the stainless steel sintered filter element should also meet the standard. The strength is related to the pressure bearing capacity of the sintered mesh filter element. The pressure in the hydraulic system is not constant. The mesh filter element must not only withstand high pressure, but also have the fatigue resistance characteristic of maintaining its own structural strength and not easily lost in the changing pressure.

How to maintain it well In the stainless steel sintered filter element, its processing quality will directly determine its service life. To prolong its service life, daily maintenance is also indispensable.

In the processing of stainless steel sintered filter element, it should have high oil passing capacity under the condition that the filtration accuracy meets the needs. The sintered mesh filter element has strong oil passing capacity to ensure smooth circulation of the system, and its pressure will also be in a relatively If the pressure difference is too large, it will not only easily damage the structure of the sintered mesh filter element, but also affect the oil absorption of the pump and the working efficiency of the transmission parts.
