          The hydraulic return oil filter is a device used to filter the circulating return oil of the hydraulic system. This device can effectively prevent pollutants in the system from harming the hydraulic system. Dongfeng Filter Company will introduce some knowledge about the production of hydraulic return oil filters.
          The production process of hydraulic return oil filter mainly includes five steps: material selection, processing, assembly, testing, and packaging.
1. Material selection
         The screen material of the hydraulic return oil filter is usually stainless steel. When selecting materials, it is necessary to consider the filtering effect of the screen on the system and the durability of the screen. Therefore, when selecting materials, it is necessary to choose stainless steel with good manufacturing quality, high temperature resistance, and low wear resistance.
2. Processing
         Screen processing is an important process in the production of hydraulic return oil filters. During the processing, it is necessary to process the raw materials into the required shape and size according to the design requirements, and the processed screen mesh needs to undergo surface treatment. The purpose of doing so is to improve the surface quality of the screen, enhance its rust resistance, and also increase its high-temperature resistance.
3. Assembly
         The hydraulic return oil filter mainly consists of three parts: a shell, a screen, and a sealing gasket. The assembly process includes installing the screen into the casing, assembling sealing gaskets, etc. During assembly, it is necessary to follow the design requirements to ensure the quality of the assembly.
4. Testing
         Testing during the production process is very important. The testing of hydraulic return oil filters mainly includes two aspects: appearance and sealing testing, and flow testing. Through appearance and sealing tests, it is possible to check for any abnormalities in the housing and screen of the hydraulic return oil filter. The flow test mainly checks whether the flow rate of the hydraulic return oil filter meets the design requirements.
5. Packaging
        The packaging of the hydraulic return oil filter is mainly to ensure the transportation and storage of the product, and to prevent damage or contamination during transportation and storage. The packaging material should be moisture-proof, shockproof, and anti-static to avoid damage to the filter or static electricity during the packaging process. At the same time, it is also necessary to indicate the product model, specifications, production date, and manufacturer information on the packaging based on the product specifications.
        In short, the quality of hydraulic return oil filter production is related to the safety and stability of the hydraulic system. Whether in the process of material selection, processing, assembly, testing, or packaging, Dongfeng Filter strictly controls the quality of the product.
