For judgment of crusher machine condition, as a technical personnel should pay attention to the following:
1. Is not the same as equipment malfunction
Some people blindly believe that equipment abnormal equals machine failure. Need to explain here, the equipment is abnormal in the process of operation, due to some problems in the internal parts, affect the normal work of the crusher, but does not explain the crusher work can not run. Equipment problems, if not timely maintenance is very easy to turn into a failure. And fault refers to a certain part of the machine has a defect, or was completely unable to run as a result of working, this kind of circumstance is failure. And equipment malfunction are two different levels of mechanical damage, should take measures is not the same, therefore cannot be confused.
2. The fault diagnosis technology and methods
There are many ways to fault diagnosis technology and the development of these techniques have been. The interview with summarizes several diagnostic method of crusher:
(1) Acoustic diagnostics: the so-called acoustic diagnostics is through the acoustic resistance and acoustic emission source and other sound equipment to test the crusher, the sound intensity measuring its voice and audio is in line with the requirements, so as to determine whether the device is damaged.
(2)Vibration diagnosis method, the vibration diagnosis by mechanical vibration diagnosis, it is the mechanical movement produced by the vibration and impact test for the goal, by detecting the vibration frequency and speed, diagnosed equipment run time whether there are abnormal, if you have to repair in time.
(3) Diagnosis: temperature diagnosis method is to use the machine temperature difference in temperature, radiation, heat dissipation as testing target, check out the temperature of the machine is working size. If the temperature is more than the design requirements, should be timely check, find overheat reasons, then, to avoid further serious problem.
(4) The intensity of diagnostics: the resilience of strength diagnosis method is through testing machine, torque, measuring the force strength whether there is a problem of the machine.
(5) Diagnosis: pressure pulsation inspections diagnosis rule is based on the machine, measuring pressure machine are in good condition.
