During the use of the crusher, maintenance operations are indispensable, which can greatly extend the service life of the crusher and ensure their working efficiency; one of the key items is the maintenance of the hydraulic system. The following explains why you should It is maintained, how to maintain the answer.
There are three basic “pathogenic” factors in hydraulic systems: pollution, overheating, and ingress of air. Practice has proved that 75% of the failures of the hydraulic system are caused by these three.
So how to keep the hydraulic system away from these three “pathogenic” factors and keep healthy? The secret lies in scientific and effective maintenance operations. Please follow the editor to experience the “maintenance gymnastics” of this hydraulic system:
Part 1: Regularly replace the filter element
When the hydraulic system is working, the fuel tank will exchange air with the outside atmosphere, and the friction between the moving parts in the system will produce small solid pollutants. Therefore, when the hydraulic system is running, the filter is always working; once the dirt holding capacity of the filter element reaches the limit and we do not replace it in time, these dangerous pollutants will produce destructive power and make your hydraulic system “sick” .
Part 2: Regularly check whether the heat exchange unit is working properly
The hydraulic system is like a “long-distance runner” when it runs. If there is a problem with its heat exchange system, it cannot “sweat” to lose heat and maintain temperature balance, then its “running” must stop.
Regardless of whether the heat exchange unit is water-cooled or air-cooled, a clean and matched heat exchange medium must be used, otherwise the heat exchange unit itself cannot work stably for a long time. Of course, the hydraulic system it serves has to stop to calm down.
Part 3: Regular exhaust
Many people seriously underestimate the harmfulness of air in hydraulic systems. If the proportion of air in the oil is too high, “cavitation” and “cavitation” will occur when passing through the hydraulic pump, which will damage the hydraulic pump and produce metal particles. A large number of metal particles are catastrophic to the hydraulic system. It may directly make the hydraulic system “end of life”.
For the hydraulic system exhaust, you may not know how to operate it. Conscience editor’s friendship sharing: The air dissolved in the oil in the fuel tank can be heated to 60°C and let it stand overnight; during this process, you will find that a large number of bubbles slowly emerge from the liquid surface and dissipate. . The pressure measuring joint at the height of the hydraulic system can also be used as an exhaust point, but this type of operation must be performed by professionals, and safety is the first priority.
Part 4: Regular pipe tightening and surface cleaning
This type of maintenance operation is actually common to mechanical parts, which helps prevent oil leakage and early detection of problems.
