Liquid PRESS failure is what causes
Failure of the hydraulic system are the following :
Fault (l) of hydraulic brick making machine failure occurs diversity may be varied , and in most cases several faults occur simultaneously . For example, the pressure of the system is unstable and noise vibration failures often occur simultaneously . Failure caused by the same reason there may be multiple , but these reasons are often intertwined with each other influence each other . For example , the system pressure is mainly the cause of which may be caused by the pump , the relief valve may be caused , there may be a result of both effects . Hydraulic systems are often the same reasons, but different symptoms in different degrees in different sleepy its system structure and its complex mechanical structure caused can be varied . Also for example, the intake air system , may cause different faults .
The complexity of the hydraulic system pressure ( 2 ) is mainly the fault is often a fault associated with the operation and even shortcomings of mechanical and electrical parts are also interwoven with the hydraulic system failure , such failure becomes complicated commissioning of new equipment even more so.
Contingency and necessity in the hydraulic system failure ( 3 ) failure is sometimes accidental, sometimes inevitable happened . Accidental fault conditions such as:
Oil accidentally stuck in the dirt or relief valve spool , the system can not be accidental loss of pressure or commutation ; occasionally change the grid voltage , so that the solenoid pull solenoid valve malfunction caused by not working properly . These failures are not often discretionary , there is no certain rules . Circumstances inevitable failure of those reasons is the continuing failure occurs frequently , and has caused a certain regularity . If the system low viscosity oil leak caused by the leakage of the hydraulic pump increases lead to a decline in the large internal clearance volumetric efficiency of the pump and so on .
( 4 ) failure analysis to determine the difficulty of the hydraulic system failure due to the presence of these characteristics, so when the system fails, the fault may not immediately be able to determine the location and causes. If the high technical level of staff expertise in this area , where the master of the situation hydraulic equipment , have the ability to carefully inspect the fault , analysis, judgment and quickly locate the fault location and its causes . But if enough professional staff of hydraulic equipment are not familiar with the situation , find out why is a certain difficulty . However, once to find out why , troubleshooting and exclude easier , and sometimes directly after cleaning or adjustment related parts can be successfully resolved.
