Oil leakage of bucket cylinders, motors, hydraulic pumps and other components is a common problem in the construction process of excavators. How to quickly find the oil leakage point of excavator oil leakage? If there is an oil leak in an unknown location, and the cause of the oil leak is unclear, it will not only cost money and effort, but also delay work time.

Basically, when there is an oil leakage problem of the excavator, the owner will first carry out simple repairs by himself, which can save costs, save time, and not delay the progress of the project, provided that the oil leakage point is identified. Today, I will introduce to you how to quickly find the oil leakage point of the excavator oil leakage and help the excavator owner to overhaul.

Let’s take a look at the fault phenomenon reported by a machine owner: the excavator leaks oil, the machine works for 2-3 minutes, and it is found that hydraulic oil seeps out of the pilot valve block. There is no abnormality in the appearance, so find a maintenance master to check.

Excavator oil leakage fault inspection:

After the maintenance worker arrives at the scene, the oil is wiped off first. Less than 3 minutes after starting the machine, the bottom plate of the valve block has begun to drip oil. Since there are only a few pipes connected to the valve block, all the pipe joints are tightened again, and the fault still exists; after replacing the new valve block, it is found that there is still oil leakage; remove the fixing screw of the solenoid valve block, lift the valve block, wipe it clean and continue Work, check quickly after working for a period of time, and finally find the oil leakage point, the original valve block processing process hole oil leaks, unscrew the hexagon socket screw in the process hole, install the small O ring, and tighten the troubleshooting.

Processing result: The maintenance master added an O-ring to the process hole to eliminate the fault.

Troubleshooting and troubleshooting requires careful observation, and we must try our best to find the cause of the failure. And some hydraulic parts, due to processing technology reasons, need to be punched, if the process holes are not handled properly, it will also cause oil leakage and other failures.

How to quickly find the oil leakage point of the excavator oil leakage? The above case is only an excavator oil leakage situation. Various situations will be encountered in the actual operation of the excavator. You must be patient and meticulous in checking the fault problem, and master as much special fault handling experience and skills as possible, so that you can determine where the fault point is as soon as possible, instead of wasting time. and energy!
