The work of the hydraulic machine cycle, the executing agency of the movement, as well as the scope of work completed.①Hydraulic velocity components, speed reference, travel, changes in the nature and scope of the load. ②The order of the parts and the interlocking action, as well as the work of the various components, such as the environment and area.
③Hydraulic system performance, such as stability, reliability, accuracy for the duration of time and out of traffic and other requirements. Other requirements, such as the quality of the hydraulic device, and economic dimensions, and so on
3, relief valve instability, such as slide-valve as a result of mis-match with the valve hole or conical valve contact with the valve seat is to be dirt stuck, damping plug holes, springs, etc. skew or failure in the valve spool jammed or hole Mobile not working, causing the system pressure fluctuations and noise. In this regard, should pay attention to cleansing, to clear the hole damping; check on relief valve, such as in case of damage, or in excess of wear and tear should be repaired or replaced in time;
4, valve adjusted properly, so that spool valve moving too fast, resulting in reversing the impact, resulting in noise and vibration. In this case, if the valve is a hydraulic valve, it should adjust the control circuit components of expenditure, so that the impact of exchange to non-smooth.
At work, hydraulic spool valve support spring, when the oil pump frequency and the pulse rate frequency or with other similar local oscillator frequency will cause vibration, noise. At this time, by changing the natural frequency of the pipeline system, change the location of control valves to increase storage or appropriate, you can vibration noise.本文来自优&文*论~文'网，

5, mechanical vibration, such as thin tubing, and more without additional fixed bend in the flow of oil out of date, especially when a higher flow rate, it is easy to jitter caused by the tube; motor and hydraulic pump imbalances of the rotating part, or in the installation when in a bad or loose coupling and so on, can produce vibration and noise. Measures should be taken are: the longer the pipeline should be separated from each other and separated from the wall and machine, the appropriate folder to install pipe supports; adjustment of the hydraulic pump motor and the installation of precision; re-install the coupling to ensure that small coaxiality 0.1MM and so on.
