1. The hydraulic system is filled with poor quality hydraulic oil, which leads to thinning of the medium and suspension of impurities, thus causing fever.
2. Pay attention to the oil level height and temperature rise at any time during work. Generally, the working temperature of the oil is more reasonable at 30-60 ℃. When the temperature rises abnormally, stop the machine to check and add hydraulic pressure before use;
3, often keep the hydraulic oil clean, add oil to filter, do not mix with other liquids, the new equipment should be replaced after three months of use, the new hydraulic oil should be replaced every six months or a year. If you work continuously in high temperature, high humidity and high dust, you need to shorten the oil change cycle.
4、630 ton hydraulic pressAssembly and disassembly of the parts, must be kept clean, no debris into the valve block pollution. The components of the system must be carefully inspected and cleaned to ensure that the oil tank, lubricating oil filling tank and pipeline are clean, corrosion-free and pollution-free.
5. The hydraulic pressure should be adjusted according to the rated working pressure within the actual needs of 25MPa. The working pressure is not too high to extend the service life of the pump and valve, save energy, and reduce the thermal system.

6. The temperature of the fuel tank in the working process should be between 55 ℃. If the oil temperature is high, stop working and wait for the oil temperature to cool down to avoid damage to the pump and seal. When the temperature is lower than 20 ℃,N32# anti-wear hydraulic oil is the working medium; when the room temperature is higher than 30 ℃,# N46 anti-wear hydraulic oil should be selected as the working medium. Oil temperature should be controlled in the range of 15~50 ℃.
7. If the equipment is not used for a long time, all adjusting knobs should be relaxed to prevent the spring from producing permanent deformation and affecting the performance of the components.
8、four-column hydraulic pressThe oil must be kept clean and replaced every six months. The second use time should not exceed 2 months. If the oil is not bad, the filter can continue to be used. The oil filter should be cleaned regularly. Any time filled with oil, must undergo strict filtration, oil spills are not allowed directly into the tank, and the liquid fuel tank is not below the oil line.
9. The equipment cannot be overloaded for a long time. The pressure of the machine is 3 tons. The pressure on the oil gauge cannot exceed
10. Check the circuit of the machine before starting up, whether there is any leakage in the oil circuit, and deal with it when shutting down630 ton hydraulic pressOil lubrication and scrub clean machine tool.
