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吨液压机装配和拆卸的部件，必须保持清洁，无杂物进入阀块污染。系统的组件必须仔细检查和清洗油箱，润滑油灌装箱和管道，确保清洁、无腐蚀、无污染。
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、四柱液压机油必须保持清洁，每半年更换一次，次使用时间不应超过2个月，如果油不坏，滤波可以继续使用，滤油网要定期清洗水箱。任何时间充油，必须经过严格的过滤，石油泄漏是不允许直接进入油箱，和液体燃料罐不低于油线。
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、开机前应检查机的电路，油路是否有渗漏现象，关机时应对630吨液压机加油润滑及擦洗清洁机床。
