Longmen hydraulic press is widely used, and the hydraulic system will be contaminated after prolonged use. In order to extend its service life, ensure safe operation, and regularly clean the hydraulic system.

Cleaning is to eliminate/remove pollution, and it is also an effective method to keep hydraulic oil, hydraulic components, and oil pipelines clean. Hydraulic components are fine parts of gantry hydraulic presses, and hydraulic oil should be used for cleaning. Kerosene, gasoline, or alcohol should not be used to avoid corrosion of hydraulic components, pipelines, seals, etc. When cleaning pipelines, non-metallic hammers and rods can be used to gently tap the oil pipes to effectively remove dirt and debris from the inner walls, but force should not be used.

During the process of cleaning the hydraulic system, the hydraulic pump element should rotate and the heating cleaning medium should be carried out simultaneously. The temperature of the cleaning oil should be controlled at 50-80 ℃, at which point rubber residue is easily removed; Clean the pipeline oil circuit, home filter or mesh, filter out impurities, achieve a new cleaning effect, clean the hydraulic pump of the hydraulic press, increase the intermittent operation of the hydraulic pump, otherwise it cannot be cleaned completely. Ensure that all hydraulic oil in the circuit is drained before cleaning the oil pipe.

Everyone knows the principle of oxidation. Apples will turn yellow after being cut open for a while. The frame hydraulic press is big, but if it is not cleaned and reacts with external air and moisture, it can also cause rust. Therefore, we remind everyone to let the hydraulic pump run continuously after cleaning to reach normal temperature.

In the production and manufacturing process, the quality of the castings of the gantry hydraulic press should be controlled and inspected. The first step is to follow the process rules and technical conditions for controlling and inspecting each specific product from raw materials and auxiliary materials. Each process needs to be controlled and inspected, and the quality of the finished castings should be inspected. Professional inspection personnel should be reasonably equipped.
