-ristics of the hydraulic system, not only to minimize eradication. Use a good quality hydraulic
oil, hydraulic piping arrangement should be avoided as far as possible the emergence of bend,
the use of high-quality pipe and fittings, hydraulic valves, etc.
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 high-speed 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. 3, the leakage of the hydraulic system leak into inside and outside the leakage leakage. Leakage
refers to the process with the leak occurred in the system, such as hydraulic piston-cylinder 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. 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 large-scale industry, construction, factories,
enterprises, as well as elevators, lifting platforms, Deng Axle industry and so on.  
     Hydraulic components will be high-performance, high-quality, high reliability, the system
sets the direction of development; to the low power, low noise, vibration, without leakage, as
well as pollution control, water-based media applications to adapt to environmental
requirements, such as the direction of development; the development of highly integrated high
power density, intelligence, mechatronics and micro-light mini-hydraulic components; active
use of new techniques, new materials and electronics, sensing and other high-tech.
---- Hydraulic coupling to high-speed high-power and integrated development of hydraulic
transmission equ- ipment, development of water hydraulic coupling medium speed and the field
of automotive applications to develop hydraulic reducer, improve product reliability and
working hours MTBF; hydraulic torque converter to the development of high-power products,
parts and components to improve the manufacturing process tech -nology to improve reliability,
promote computer-aided technology, the development of hydraulic torque con- verter and
power shift transmission technology supporting the use of ; Clutch fluid viscosity should
increase the quality of products, the formation of bulk to the high-power and high-speed
direction.
