What are the leaks in the Komatsu 220-6 hydraulic system?
This article mainly tells about the leakage of the hydraulic system of the small pine excavator, what influence the leakage of the hydraulic system of the excavator will have and how to prevent the leakage of the 220-6 hydraulic system of the Komatsu.
What kinds of hydraulic system leakage can be classified into Komatsu excavator?
Leakage: the hydraulic fluid of the hydraulic system crosses the boundary for some reason and flows to the other cavity or outside of the system that it should not go into.
Type: leakage from the high pressure chamber of the component to the low pressure cavity becomes internal leakage.
Leakage from components or piping to external leakage becomes leakage.
According to the leakage mechanism, they are divided into: leakage of gaps, leakage of pores, adhesion leakage and dynamic leakage.
Leakage and leakage of leakage in hydraulic system
Leakage: joints, valve mounting surfaces, pipes, etc. are visible and visible leaks.
Internal leakage: cylinder piston seal ring, pump plunger, spool and so on.
What are the effects of the leakage of the hydraulic system:
1 the leakage of the 220-6 hydraulic system of the Komatsu, the relative motion pair of the movement, the connection of the pipeline, the leakage of the leakage of the hydraulic components, which causes the pollution of the oil to the environment, the waste of the oil and the decrease of the mechanical efficiency, which will also cause the instability of the system work and the damage of the system.
2 leakage will cause insufficient pressure, the excavator will not work up to the workpiece, or machinery will be dangerous.
How to prevent the leakage of the Komatsu 220-6 hydraulic system:
The 1 interface is less.
2 the quality of products is good, and the chance of leakage is small.
3 operation: pay attention to maintenance, especially cleaning - oil circuit.
4 now there is a non welding connection is not bad, flaring flange connection, card sleeve connection, etc., can be better than welding, no stress artificial welding damage.
