When using the hydraulic pump of the mixer, the failure of the hydraulic system will greatly reduce the performance of the mixer. It is suggested to understand the causes of the hydraulic system failure of the mixer, eliminate and maintain the fault, so that the mixer can resume normal operation without affecting the working time. Let's look at how to detect a hydraulic pump fault in the automatic feed mixer.
Smell: does nose smell hydraulic oil? If you are worried about the smell of the hydraulic oil, you can identify it as a high temperature component, because the hydraulic components such as the hydraulic pump are partially heated and the hydraulic oil will burn and smoke. Check the hydraulic oil for unpleasant or irritating odor. If the hydraulic oil is very dirty, it cannot be used.
Visual diagnosis method: visual inspection of the operation status of the hydraulic system, and observe the pressure value and temperature change of each pressure measuring point of the hydraulic system to check whether the oil is clean and whether the oil quantity is sufficient. Observe the hydraulic valve and pipe joint, hydraulic cylinder end cover and hydraulic pump drive shaft for oil leakage. In the process of equipment processing, observe the product or conduct performance test to check the working condition of mobile mechanism, the stability of system pressure and flow and the working condition of solenoid valve.
Hearing diagnosis: the ear determines whether the hydraulic system or component is working properly. Listen to the hydraulic pump and hydraulic system for excessive noise, listen to the abnormal sound on the relief valve and other parts, if the impact is too big, listen to the workbench, and then operate the piston at the bottom of the hydraulic cylinder. Listen to the sound.
Tactile diagnosis method: touch the temperature and working state of moving parts, and touch the temperature of hydraulic pump housing, oil tank outer wall and valve body shell. The room temperature is about 55 ℃. If the temperature exceeds 60 ° C, the cause needs to be checked. Touch moving parts and pipes and feel obvious vibration.
This is how everyone shares it to detect a hydraulic pump fault in the automatic water mixer. If there is a fault in the operation of the hydraulic pump of the mixer truck, the corresponding program can be used for detection.
