analysis of hydraulic system failure
2023-10-13
Along with hydraulic technique's development, the hydraulic system is wide spread in various Industry sector's application day by day. Therefore guaranteed that hydraulic system's normal movement, increases the work reliability to be important, selects the hydraulic fluid variety and viscosity correctly is the first condition for guarantee system long-term,reliable work. On the other hand, when the hydraulic system broke down, can rapid find the reason and the effective solution is also very important. The hydraulic is equipment by machinery, hydraulic pressure, electricity and measuring appliance, in order to analysis hydraulic system's breakdown must understand entire hydraulic system's transmission principle,unique feature and the part and the material disposition situation.Because the hydraulic system is sealing tape presses system, in the pipeline fat liquor mobility status, the hydraulic internal components movement and seals whether to damage is not easy to observe, therefore is difficult to analysis breakdown's reason and diagnosis's spot.
Many reason will cause the hydraulic system breakdown, induces has three aspects:
First, equipment's mechanical breakdown, this includes the hydraulic system design unreasonable, the installment gap is not correct, the hydraulic element quality question, the seal selects and so on improper, causes the hydraulic system breakdown by these questions not to relate generally with the hydraulic fluid.
Second, the operate miss creates the hydraulic system breakdown, because this is refers to the hydraulic system operators operates improper creates in the normal work time, like the wrong make and break valve, sudden power source stop,operating temperature or the pressure are excessively high, makes up when the oil add the wrong oil quality, fuel tank oil level have been excessively low, emits the separation not promptly from the fuel tank base the water and so on. Because the operate miss creates the hydraulic system breakdown, is not the hydraulic fluid quality question creates, does not involve the hydraulic fluid mostly, but some may reflect from the hydraulic fluid mass variation.
Third, because the hydraulic fluid quality creates the hydraulic system breakdown, this mostly because chose the improper oil or has used the unqualified oil, also possible created by long working time of hydraulic oil or long time no replace.
