1. Prevent hydraulic oil leakage
Engineering hoses are used to transmit working pressure. When the pressure in the hydraulic oil circuit drops to the normal working pressure, gas will leak out of the oil again. When hydraulic oil leaks into the air, it can cause an explosion. Therefore, the oil pipe must have good sealing and corrosion resistance to prevent oil pollution. When the excavator is working, ensure that the hydraulic oil does not leak, so that the excavator can work normally. This is one of the very important links for excavators. Having a hydraulic hose is equivalent to having a safety line of defense!
2. Ensure the stable output of excavator digging force
Since the hydraulic system is composed of many components, each component will be affected by various factors during work. Among them, the hose plays an irreplaceable role in this process. For example, when an excavator is working, some excavators have a lot of soil and sand in the bucket. At this time, hoses are needed to limit the digging of soil and sand by the excavator, and prevent the soil from splashing on the hose and causing the machine to Injuried. If the excavator encounters unexpected movements when it is working, it will cause the excavator to deform, which will cause the excavation force to be unbalanced. When working, it is easy to have problems such as the excavator cannot move or cannot be pushed, and the hydraulic hose needs to be replaced. For example, when the excavator can't dig, the excavator starts to malfunction. At this time, if we still use the hose, we can prevent the excavator from having an unbalanced digging force, and it can also ensure that the excavator can normally complete the excavation task under any conditions or the normal movement of the bucket rod can work normally. The damage to the excavator is reduced, and the work efficiency of the excavator is also improved.
3. Reduce excavator vibration and noise
Since the hydraulic hose is made of rubber material. When the excavator uses hydraulic hoses, the vibration and noise of the excavator are greatly reduced, the work efficiency is improved, and the noise of the excavator itself is reduced. The main reason is that the hydraulic hose can greatly reduce the vibration of the excavator when it is working. Secondly, because the excavator will make a certain noise when it is working, but the hydraulic hose will not make noise.
4. Reduce the working pressure of the excavator
The joint part of the hose, usually a rubber hose, is used to fix and limit the pressure when the excavator is working. If the pressure is too high, it will generate heat and burst; if the pressure is too low, the excavator will not work properly. The material of the hose is usually made of high-strength and high-elasticity materials, and its function is to prevent deformation and impact and ensure the safety of mechanical parts. In addition, it can also play an anti-slip effect. Another function is to prevent the operator or driver from causing unnecessary damage to the cab when driving. Therefore, when operating the excavator, we must pay attention to whether the hydraulic pipes and hoses are in good condition or whether the quality is qualified and whether they are replaced in time. If it is found to be aging or broken, it must be replaced in time. The following is about the use and maintenance methods and precautions of excavator hydraulic pipes. When the excavator is working, the pressure and temperature changes will cause the oil temperature to rise and leak, which will affect the hydraulic system. And it will generate heat and cause damage to mechanical parts, which is why it takes a long time to use hoses and cannot be replaced. So timely replacement and maintenance is very necessary.
5. Protect the hydraulic system
When the hose is too long, the pipeline distance can be shortened to prevent leakage. Filter the oil. When the lumen is blocked, the oil can be discharged from the tube through the hose. Prevent oil from seeping into hydraulic lines or hydraulic pumps. Reduce the vibration of the hydraulic oil pump and protect the hydraulic system. Extended service life.
