Hydraulic fittings system which causes abnormal pressure

Hydraulic fittings system pressure anomalies generally reserved for system piping design a lot of pressure measuring points , measured using the pressure gauge readings , and comparative analysis to determine the cause of the normal abnormal pressure of the Hydraulic ferrules components. Velocity anomalies individually adjustable throttle, variable speed control valve and variable pump body , corresponding to the test speed of the actuator range values ​​, comparative analysis with the design values ​​can be determined . Each movement abnormalities switching valve, observe the actions related to the implementation of components status is normal , you can find out the abnormal valve, then check the action sequence and stroke control , identify exception handling . Other abnormal vibration, noise , oil spills, heat , etc., do not be turned off , it should be exactly two see three observation and analysis process to determine abnormality .Integrated hydraulic fittings used in Hydraulic adapters fluid mechanics knowledge , theoretically hydraulic fittings and hydraulic components for hydraulic circuits any failure analysis. The following example will be explained the general failure of hydraulic fittings lookup process . Fault Name : hydraulic pump cavitation ; failure phenomenon : vibration, noise , cavitation ; main reasons: the pump suction pressure is lower than the gas separation pressure , or inhaled air . Inference analysis : the use of the energy equation and the continuity equation for flow pump suction process analysis, determine the hydraulic fittings hydraulic pump failure reasons: oil level is too low --- pressure tank vents clogged pump inlet flow rate is too high.
