Rack punching machine Fault problems will be encountered during work. Diagnose the shelf Punching machine There are many failure methods for,
The rack punching machine can be simply divided into eye, nose and ear.
1、 Eyesight
Is to see through the eyes Rack punching machine Operation of the system.
If the oil volume in the oil tank meets the requirements, whether there are bubbles and discoloration.
Oil leakage at sealing part and pipe street;
Change of indicated value of pressure gauge and oil temperature gauge during operation;
Check whether the fault part is damaged, the connection is gradually falling off and the fixing parts are loose.
2、 Nasal olfaction
It's just to smell for abnormal smell,
If there is a special smell, the construction shall be stopped immediately for inspection and testing.
3、 Hear
Listen to the hydraulic system for abnormal noise.
The sound of normal machine operation has a certain rhythm and rhythm and is stable.
Therefore, if we are familiar with and master these rules, we can accurately diagnose whether the hydraulic system works normally;
At the same time, according to the changes of rhythm and rhythm, and the components produced by abnormal sound,
Then we can determine the parts where the fault occurs and the damage degree.
Such as high pitched shriek, usually inhaled air; The "chatter" or "gurgle" of hydraulic pump is often caused by damage of pump shaft or bearing;
The reversing valve makes a "wheezing" sound, which is due to the insufficient opening of the valve stem; The rough "clatter" may be the sound of overload valve overload.
If there is cavitation noise, it may be that the oil filter is blocked by dirt, the suction pipe of the hydraulic pump is loose, or the oil level of the oil tank is too low.
