Leakage refers to the process with the leak occurred in the system, such as hydraulic pistoncylinder on both sides of the leakage, the control valve spool and valve body, such as between the leakage. Although no internal leakage of hydra ulic fluid loss, but due to leakage, the control of the established movements may be affected until the cause system failures. Outside means the occurrence of leakage in the system and the leakage between the external environment. Direct leakage of hydraulic oil into the environment, in addition to the system will affect the working environment, not enough pressure will cause the system to trigger a fault. 7 Leakage into the enviro nment of the hydraulic oil was also the danger of fire. Solution: the use of better quality seals to improve the machining accuracy of equipment. 泄漏 液壓系統(tǒng)的泄漏分為內(nèi)泄漏和外泄漏。避免頻繁改變液流方向，無法避免時應(yīng)做好減 振措施。強的振動會導(dǎo)致系統(tǒng)控制動作發(fā)生錯誤，也會使系統(tǒng)中一些較為精密的儀器發(fā)生錯誤，導(dǎo)致系統(tǒng)故障。 2, the vibration of the vibration of the hydraulic system is also one of its malaise. As a result of hydraulic oil in the pipeline flow of highspeed impact and the control valve to open the closure of the impact of the process are the reasons for the vibration system. Strong vibration control action will cause the system to error, the system will also be some of the more sophisticated equipment error, resulting in system failures. Solutions: hydraulic pipe should be fixed to avoid sharp bends. To avoid frequent changes in flow direction, can not avoid damping measures should be doing a good job. The entire hydraulic system should have a good damping measures, while avoiding the external local oscillator on the system. 振動 液壓系統(tǒng)的振動也是其痼疾之一。解決辦法：發(fā)熱是液壓系統(tǒng)的固有特征，無法根除只能盡量減輕。溫 度升高將導(dǎo)致內(nèi)外泄漏增大，降低其機械效率。在接觸式密封中，分為自封式壓緊型密封和自封式自緊 6 型密封（即唇形密封）兩種。它的工作的可靠性和使用壽命，是衡量液壓系統(tǒng)好壞的一個重要指標。侵入系統(tǒng)中的微小灰塵顆粒，會引起或加劇液壓元件摩擦副的磨損，進一步導(dǎo)致泄漏。外漏會造成工作介質(zhì)的浪費，污染機器和環(huán)境，甚至 引起機械操作失靈及設(shè)備人身事故。 In the hydraulic system and its system, the sealing device to prevent leakage of t
