Five main points of hydraulic press maintenance


Hydraulic presses are widely used in the machinery industry, but hydraulic presses need to be maintained in daily life. Many people do not understand the maintenance methods of hydraulic presses. Below, Shanghai WORLD Press Machine will share five major maintenance points for hydraulic presses.



1. The liquid level of the fuel tank should always be kept at a sufficient height, so that the oil in the system has sufficient circulating cooling conditions, and pay attention to keep the fuel tank, oil pipes and other equipment clean to facilitate heat dissipation. Generally, the oil temperature of 30℃-55℃ is the most suitable temperature for safe use, with the highest performance and longest life.



2. Hydraulic oil is the energy transmission medium when the hydraulic station works. The quality, cleanliness and viscosity of the hydraulic oil play a dominant role in the life of the hydraulic pump, hydraulic valve and hydraulic cylinder. Therefore, great attention should be paid to the hydraulic oil when using the hydraulic station. quality and keep the hydraulic oil clean. The oil used in the hydraulic system must be strictly filtered, and an oil filter should be configured in the hydraulic system.



3. The hydraulic oil needs to be replaced once a year, and the first replacement time should not exceed three months; in order to ensure the reliable operation of the press, it is recommended that the user must replace some components of the press after reaching the service life cycle.



4. The slider should always be filled with lubricating oil, the exposed surface of the column should be kept clean, and the oil should be sprayed before each work. In order to prevent dust and water from falling into the oil, the surrounding area of ​​the oil tank should be kept clean and maintenance should be carried out regularly.



5. The working pressure of the system is to adjust the output pressure of the hydraulic pump through the pressure regulating valve. In general, the set pressure cannot exceed its original design rated pressure, otherwise it may cause damage to the hydraulic pump, hydraulic valve stuck or motor burnout and so on. The maximum allowable eccentricity of concentrated load is 40mm under the nominal pressure of 500T. If the eccentricity is too large, it is easy to strain the column or cause other undesirable phenomena.



The above are the five key points of hydraulic press maintenance. If you understand these points, you can do better when you maintain them.
