Instalace a údržba čtyřsloupového hydraulického lisu
1. Installation of four-column hydraulic press machine
Strongest hydraulic press, Before the hydraulic machine is installed, the installation foundation should be prepared in advance. Generally, a concrete foundation is used. The hydraulic machine body is fixed by bolts, so bolt holes should be reserved when making concrete foundations, and poured and fixed after the hydraulic machine is installed. For the installation of other components of the hydraulic press, refer to the assembly drawing of the component, and install according to the cooperation requirements given in the drawing.
2. Commissioning of four-column hydraulic press machine
Strongest hydraulic press, After all, the installation work of the hydraulic press is completed, it must be commissioned on site. Press the start button to see if the hydraulic press can complete the actions of each working order in the sequence. During the debugging process, see whether the hydraulic press hardware or control system works normally by watching, listening, etc. In addition, verify that all control buttons and pressure gauges are working properly. After a period of commissioning, if the operation is normal, the hydraulic press can be officially delivered.
3. Maintenance of four-column hydraulic press machine
(1) It’s important to choose the right hydraulic fluid
Strongest hydraulic press, Hydraulic oil plays the role of transmitting pressure, lubricating, and cooling in the whole system. If the hydraulic oil is not selected properly, the hydraulic system will malfunction and degrade. In general, refer to the random instruction manual and select the specified type of hydraulic oil. In special cases, you can choose a substitute oil with the same nature as the specified type. Different grades of hydraulic oil cannot be mixed to avoid chemical reactions. Dark brown, milky white, and offensive oil with bad smell cannot be used.
(2) Regular maintenance
Strongest hydraulic press, Remove the dirt on the filter regularly and replace it if the filter is damaged. After working for a period of time, the equipment should clean the filter and hydraulic oil tank, and replace the hydraulic oil in time. When it is under high-temperature conditions for a long time, the cleaning and replacement cycle should be shortened. When the hydraulic press is working for 10,000 hours, professionals must be tested for the equipment, adjusted, and repaired to prevent fatal damage to the hydraulic system and equipment due to prolonged disrepair.
(3) To prevent solid impurities from entering the system
Strongest hydraulic press, When adding or replacing hydraulic oil, the oil should be filtered to prevent solid impurities from invading the system from blocking the oil path, especially precision parts, which are easy to block. When cleaning the fuel tank, the disassembled parts should be wrapped up to avoid contamination by debris. The cleaning fluid of the fuel tank should be hydraulic oil of the same brand and repeatedly cleaned about three times.
(4) To prevent air from entering the system
Hydraulic press machines are high-pressure equipment. A large amount of air intrusion will aggravate the phenomenon of “cavitation”. In addition, the system will cause increased operating noise, unstable transmission, reduced efficiency, easy oxidation, and deterioration of the oil, and sometimes a “crawling” phenomenon in the hydraulic system.
(5) To prevent the hydraulic oil temperature from working too high
The working temperature of hydraulic oil should generally be controlled between 30 ° C and 80 ° C. Excessive oil temperature will cause the viscosity of the hydraulic oil to decrease, which will easily cause leakage, reduce efficiency, reduce the strength of the lubricant film, accelerate the wear of the machinery, and generate carbonization. Materials and sludge, the oil oxidation accelerates, and the oil quality deteriorates; when the oil temperature is too low, its viscosity is large, the fluidity is poor, the resistance is large, and the work efficiency is low.
