Preventing Oil Leakage in the Hydraulic Oil Pipes of the Forming Hydraulic Press: Insights from Hydraulic Press Manufacturers
1. Proper Tightening of Fastening Nuts: All types of fastening nuts on the forming hydraulic press must be tightened according to the specified torque. Overly loose nuts can cause leaks, as the gasket may not be compressed tightly. Conversely, over-tightening can result in metal protrusions around the screw holes or cause the threads to slip, leading to oil leakage. Additionally, if the drain plug on the oil sump is not tightened or becomes loose, it can lead to oil loss and, subsequently, bearing seizing incidents.
2. Timely Replacement of Failed Oil Seals: Many dynamic positions on the hydraulic press may experience oil splashing due to improper installation, misalignment between the shaft neck and the oil seal edge, or eccentricity. Some oil seals may lose elasticity due to aging after prolonged use.
3. Importance of Gasket Function: Gaskets between static components of the hydraulic press play a role in preventing leakage and providing sealing. If the materials, manufacturing quality, and installation do not meet technical specifications, they may fail to achieve effective sealing, leading to accidents.
4. Avoiding Hub Oil Splashing: Hub bearing and excessive lubricating grease inside the cavity, improper assembly of oil seals, poor quality, aging, frequent braking leading to high hub temperatures, and loose hydraulic press shaft nuts can all contribute to hub oil splashing.
5. Properly Addressing Various Oil Pipe Joint Seals: Frequently dismantling and assembling union nuts on the hydraulic press can lead to thread slippage or detachment, causing oil seepage. Replacing union nuts and using a grinding method to address the conical surface seal ensures proper tightening and effective sealing.
6. Preventing Clogging of Check Valves and Vent Valves: Clogging of these valves can lead to an increase in temperature inside the housing, filling the space with oil and gas that cannot be released. This can result in elevated pressure inside the housing, increased lubricant consumption, and a shortened replacement cycle. A blocked engine venting system increases piston movement resistance, leading to increased fuel consumption. The pressure difference between the inside and outside of the housing often causes oil leakage at weak sealing points. Therefore, regular inspection, clearing, and cleaning of the hydraulic press are necessary.
