The high temperature of hydraulic oil can not be ignored, because it will bring serious consequences. The excavator will also have the following symptoms:

　　1. The viscosity of the oil decreases, the leakage increases, and the system heats up, forming a vicious circle;

　　2. Accelerate the oxidation of oil, form colloidal substances, block the small holes of components, make the hydraulic components failure or stuck, unable to work;

　　3. Aging of rubber seals and hoses;

　　4. The wear of oil pump and hydraulic valve is aggravated, even scrapped.

　　Many people change the hydraulic oil without quality problems, but later there are still a variety of small problems, but I do not know how much oil will also have a huge impact on the excavator itself!

　　If it's true, you'll know after watching it!

　　The disadvantages of adding more:

　　1. If the hydraulic oil is filled too much, the resistance of the hydraulic system will increase, and the working space will become smaller. If the hydraulic oil is filled too much, the ventilation filter (vent valve) on the hydraulic oil tank may be damaged.

　　2. Too much hydraulic oil will cause too much pressure of hydraulic oil, which will lead to damage of 0-ring of hydraulic oil pipe and seals of hydraulic components.

　　3. Excessive hydraulic oil will increase the temperature of the excavator, resulting in high temperature of the hydraulic system. Some friends hydraulic system high temperature always can not find the reason, may be the hydraulic oil more!

　　So a friend said that more harm is so much, can I add less? Of course not, there are also many harm. Look down!

　　The disadvantages of less

　　1. After the lack of hydraulic oil, the hydraulic pump will absorb oil and empty, which will lead to high system temperature and abnormal noise of the hydraulic pump, which will aggravate the wear of the hydraulic pump components, and in serious cases, the hydraulic pump will be damaged.

　　2. After the lack of hydraulic oil, all the action actuators of the excavator will be unable to work and unstable, which seriously affects the work of the excavator.

　　3. After the lack of pressure oil, there will be bubbles in the pipeline of the hydraulic system, which will lead to insufficient digging force of the excavator, and easily lead to serious consequences such as the wear of the distribution valve stem and oil cylinder.
