The temperature is gradually dropping. Today, I will share with you the maintenance guide for hydraulic presses that can be often used in autumn and winter, to face the cold weather with sufficient professional knowledge.
Careful maintenance and strict implementation of safe operation procedures are necessary conditions to prolong the service life of equipment and ensure safe production. In addition to being familiar with the structure and performance of the machine, the operator should also pay attention to equipment maintenance.
1. The debugging and maintenance of the hydraulic station requires professionals. When the hydraulic components are disassembled, the parts should be placed in a clean place, and the sealed surface should not be scratched.
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 press clean. The oil used in the hydraulic system must be strictly filtered, and an oil filter should be configured in the hydraulic system.
3. Under the condition of ensuring the normal operation of the system, the pressure of the hydraulic pump should be adjusted as low as possible, and the pressure of the back pressure valve should be adjusted as low as possible to reduce energy loss and heat generation.
4. In order to prevent dust and water from falling into the oil, the surroundings of the oil tank should be kept clean and regular maintenance should be carried out.
5. 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 parts 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.
6. Try to prevent the pressure everywhere in the system from being lower than the atmospheric pressure. At the same time, a good sealing device should be used. When the seal fails, it should be replaced in time. All stress screws should be tightened regularly to prevent loosening and prevent air from entering the hydraulic system and leaking. Oil.
7. For systems with water coolers, sufficient cooling water should be maintained and the pipelines should be unblocked.
8. For systems with air coolers, ventilation should be kept smooth to prevent the oil temperature from being too high.
9. For a system with a filter, the filter element should be cleaned or replaced regularly (about 30 days) to prevent the filter from being blocked and the oil temperature rising too fast, which will cause the hydraulic components or oil pump to rupture in severe cases.
10. 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 should not exceed its original design rated pressure, otherwise it may cause hydraulic pump damage, hydraulic valve stuck or motor burnout.
11. In order to ensure the reliable operation of the hydraulic press, it is recommended that the user must replace some components of the press after reaching the service life cycle.
12. Hydraulic press operation, safety first! Routine maintenance is carried out under the condition of power failure, and the main problems that have been solved and unresolved in the maintenance are recorded in the file, as the data basis for the next maintenance or maintenance plan.
