The hydraulic pipe is a relatively delicate part on the excavator, and a set of original hydraulic pipes is expensive.
To prolong the service life of hydraulic pipes, the main thing is that the driver should act softly when working, and do not do high-intensity and high-risk actions. In addition, proper maintenance methods also greatly affect the life of hydraulic pipes.
1. Be sure to use a protective ring
Gear pumps and plunger pumps have oil pulsation when they work, and this pulsation will cause high-frequency vibration in the hydraulic pipe, which cannot be completely eliminated. Therefore, the hydraulic pipe has a special protective ring on the outside, the pipe (plastic sleeve) at the root of the boom and the pipe (wire sleeve) at the head of the forearm. This kind of protective sleeve is very effective.
2. Don't rub
The hydraulic pipes of some excavators are self-provided later, and the length is not suitable, and it is easy to interfere with the big and small arms or cause bending. Interference and friction will wear the outer wall of the hydraulic pipe and cause the outer wall to become thinner locally. Under the action of high pressure, it is easy to burst the pipe. The bending of the hydraulic pipe will cause the local pressure to increase and the local temperature to rise, which will easily cause the hydraulic pipe to explode.
3. Do not touch diesel gasoline
Try not to let the hydraulic pipe come into contact with diesel and gasoline, although the hydraulic pipe is resistant to oil. However, diesel and gasoline are still corrosive to a certain extent. Generally, rubber will swell and fluff when soaked in gasoline and diesel for a long time.
4. Grease the interface
The bottom of the center oil separator and the travel motor cover must be regularly cleaned and then coated with calcium-based butter to form a protective layer, and the buckle pipe should also be coated to avoid corrosion in these places. Especially the coastal areas are often exposed to sea breeze and sea water, and the buckle pipe is prone to corrosion.
5. The installation should be in place
When installing the pipe on the excavator, be sure to confirm whether it is tightened. If it is not tightened, it is a trivial matter to vibrate and leak oil. If it vibrates and wears the interface plane, it will be troublesome.
6. No. 46 hydraulic oil is easy to use for new cars
It is recommended that the new car should use No. 46 hydraulic oil. Generally, No. 46 hydraulic oil can be used to ensure the working strength of the excavator after working for more than 10,000 hours.
