【正文】 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. 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. Another: the hydraulic system for the three diseases, it was summed up: fever, with a father(This is the summary of the northeast people). Hydraulic system for the lifts, excavators, pumping station, dynamic, crane, and so on largescale industry, construction, factories, enterprises, as well as elevators, lifting platforms, Deng Axle industry and so on. Hydraulic ponents will be highperformance, highquality, high reliability, the system sets the direction of development。 directional control valve includes a oneway valve , oneway fluid control valve, shuttle valve, valve and so on. Under the control of different ways, can be divided into the hydraulic valve control switch valve, control valve and set the value of the ratio control valve. 7 Auxiliary ponents, including fuel tanks, oil filters, tubing and pipe joints, seals, pressure gauge, oil level, such as oil dollars. Hydraulic oil in the hydraulic system is the work of the energy transfer medium, there are a variety of mineral oil, emulsion oil hydraulic molding Hop categories. The role of the hydraulic system is to help humanity work. Mainly by the implementation of ponents to rotate or pressure into a reciprocating motion. Hydraulic system and hydraulic power control signal is posed of two parts, the signal control of some parts of the hydraulic power used to drive the control valve movement. Part of the hydraulic power means that the circuit diagram used to show the different functions of the interrelationship between ponents. Containing the source of hydraulic pump, hydraulic motor and auxiliary ponents。 ship from the deck heavy machinery (winch), the bow doors, bulkhead valve, stern thruster, etc.。 operating machinery engineering 6 machinery, construction machinery, agricultural machinery, automobiles, etc.。s first hydraulic press. Media work in 1905 will be replaced by oilwater and further improved. After the World War ,because of the extensive application of hydraulic transmission, espec ially after 1920, more rapid development. Hydraulic ponents in the late 19th century about the early 20th century, 20 years, only started to enter the formal phase of industrial production. 1925 Vickers (F. Vikers) the invention of the pressure balanced vane pump, hydraulic ponents for the modern industrial or hydraulic transmission of the gradual establishment of the foundation. The early 20th century G ? Constantimscofluct uations of the energy carried out by passing theoretical and practical research。 液壓元件將向高性能、高質(zhì)量、高可靠性、系統(tǒng)成套方向發(fā)展；向低能耗、低噪聲、振動(dòng)、無泄漏以及污染控制、應(yīng)用水基介質(zhì)等適應(yīng)環(huán)保要求方向發(fā)展；開發(fā)高集成化高功率密度、智能化 、機(jī)電一體化以及輕小型微型液壓元件；積極采用新工藝、新材料和電子、傳感等高新技術(shù)。外泄漏是指發(fā)生在系統(tǒng)和外部環(huán)境之間的泄漏。整個(gè)液壓系統(tǒng)應(yīng)有良好的減振措施，同時(shí)還要避免外來振源對(duì)系統(tǒng)的影響。由于液壓油在管路中的高速流動(dòng)而產(chǎn)生的沖擊以及控制閥打開關(guān)閉過程中產(chǎn)生的沖擊都是
