What Is The Reason For The Discoloration Of The Hydraulic Cylinder Of The Mucking Machine?
When the master of the small mucking machine was replacing the hydraulic oil, he found that the oil cylinder of the mucking machine showed discoloration. The idea in his mind was that the quality of the hydraulic cylinder was not good, whether he bought a product of poor quality, or whether the hydraulic cylinder appeared. In fact, this judgment is a bit decisive. There are many reasons for the discoloration of the oil tank. Don't blame the oil tank. So let's see why.
1. Pay Attention To The Heat Dissipation Of The Tunnel Mucking Machine
The masters of the tunnel mucking machine should know that the color change of the crawler mucking loader cylinder is staged, and the color gradually deepens from the light color. Under normal conditions, the slag skimmer cylinder will first turn blue, then darken, turn purple, and finally black.
The phenomenon that the crawler mucking loader cylinder turns into different colors is actually a color film on the surface of the cylinder, not the problem of the cylinder itself. When this phenomenon occurs, it is likely that there is a high temperature phenomenon in the hydraulic system. During the operation of the oil cylinder, the piston rod is frequently in contact with the low temperature environment under high temperature (especially in the cold season) (caused by the sudden drop in temperature). It is generally caused by the high temperature of the hydraulic oil, and this phenomenon mostly occurs in the first half of the bucket cylinders that are used more, or the big and small arm cylinders. It is recommended that the dust in the radiator part of the crawler mucking loader be cleaned frequently to ensure the heat dissipation effect.
2. Note That The Tunnel Mucking Machine Should Not Be Mixed With Hydraulic Oil
In addition, regarding the selection of hydraulic oil for small tunnel mucking machines, it is necessary to use special hydraulic oil instead of mixing several oils.
The discoloration of the oil cylinder is a relatively common phenomenon. Don't be nervous. In fact, the product quality of the tunnel mucking machine itself is generally no problem. Let's consider whether the temperature control during the working process exceeds the corresponding requirements of the mucking machine itself, or the selection of hydraulic oil is not appropriate.
