Cleaning of hydraulic valve parts of four-column hydraulic press

Now, as usual, manufacturers pay more attention to the cleaning of the valve body, the cleaning of the spool valve and other parts is not very good, but in actual production, the cleanliness of the spool valve is not up to standard, which leads to the decline of the quality of the spool valve. The equipment has a high qualification rate, and the two-beam four-column hydraulic press is reliable. Symptoms of low sexual intercourse also occur from time to time. As for the cleaning of parts, there are many types and a lot of work. The cleaning of the parts includes the cleaning of burrs and dirt, and the chrome-plated parts also include the cleaning of residual chromic acid in the inner holes. The cleaning of the parts of the two-beam four-column hydraulic press can be cleaned with ultrasonic waves, and then rinsed with air and water. The finish of the inner bore before cleaning is relatively tight and usable. Use drills, reamers and brushes of the same diameter to remove dust from the inner holes, and the small holes should be cleaned one by one. The cleaning structure and method of the parts are similar to those of the valve body, but should be flushed with high pressure and small flow of air-water hydration. No need for high pressure cleaning with diesel or aqueous solutions with rust inhibitors. The subsidized processing of hydraulic valves is a huge system engineering. It involves a very common category. It not only needs to provide protection against configuration, but also practice, summarize and improve skills. It must also be handled and managed carefully. Only in this way can we subsidize the machining of hydraulic valves.
