stay Design of hydraulic station The application of hydraulic cylinder has many advantages. After the surface of metal products is cold rolled, the ultimate strength, compressive strength and yield limit of the surface layer will be improved. The characteristics, fatigue relieving characteristics and wear resistance of the hydraulic cylinder products will be greatly improved. The strength and wear resistance of the workpiece after cold rolling can be increased by 15-30% and 15% respectively.
The rolling process of hydraulic cylinder can improve the surface roughness from ra6.3 to ra2.4 to Ra0.2, and the production efficiency is high. Some parts can be completed in a few minutes or seconds in use, which solves the key problems that are difficult to realize in some process methods.
The hydraulic cylinder is used to avoid cavitation. Although there are many reasons for cavitation, it can be prevented if necessary measures are taken to prevent it. It is necessary to strictly control the selection of hydraulic oil and strictly select the hydraulic oil according to the oil specification. Selecting the hydraulic oil with high cost performance ratio can reasonably avoid the occurrence of vapor bubbles in the hydraulic transmission system.
When selecting oil, the hydraulic cylinder should be selected according to the low temperature in different areas Hydraulic system At the same time of cleaning, the hydraulic oil should be added according to the oil quantity standard, and the oil quality, oil level and oil color of the hydraulic oil should be regularly checked. If the hydraulic oil foam, foam or oil turns milky white, the source of air in the oil should be carefully found and eliminated in time.
in use Hydraulic station In the use of hydraulic impact can reduce the heat dissipation coefficient of the reasonable design, effectively prevent the oil temperature is too high, is the key to maintain the normal hydraulic oil temperature.
