Hydraulic vibration system is also one of its ills. Due to the impact of the hydraulic oil in the pipeline and a high-speed flow generated by the impact of opening the control valve is closed during the generation of vibration phylogenetic reasons. Strong vibrations may cause the system to control the motion error occurs, the system will also make some of the more sophisticated equipment error occurs, causing the system failure.
?
Workaround: Hydraulic lines should be fixed to avoid sharp bends. Avoid frequent changes in flow direction, damping measures can not be avoided should do. The entire hydraulic system should have good damping measures, but also to avoid the influence of external vibration source on the system.

Third, leak
Hydraulic system leak into the leakage and external leakage. It refers to the process of internal leakage leakage occurs within the system, such as a hydraulic cylinder piston on both sides of the leak, the leak valve control valve between the arts and the like. Although no loss of internal leakage of hydraulic oil, but because of a leak, the established control action may be affected, and even cause the system to malfunction. Refers to external leakage occurs between the system and the external study mirrors leaks. Direct hydraulic oil leaking into the environment, in addition to the system will affect the work environment, it will also cause the system pressure is not enough malfunction. The risk of leakage to the environment as well as fire hydraulic oil.

The solution is usually: use high-quality seals, improve the precision of the device. For hydraulic systems of these three illnesses, it was summarized: "fever, diarrhea with Joseph"
Installation of hydraulic pump manufacturers _ hydraulic pipes should pay attention to what?
Hydraulic piping installation requirements:
Hydraulic station equipment installation project is the installation of a main hydraulic pipes. One of the key properties of the hydraulic system is normal that the pipe installation is good or bad quality.
1, piping design and pipe should be based on hydraulic schematic diagram of the components required for connection, pipe fittings, hydraulic components, flange to make a comprehensive consideration.
2, the direction and laying the pipeline should be neatly arranged in a consistent, structured. Maximize the use of vertical or horizontal piping, not vertical degrees vertical pipe should be ≤2 / 400, not parallel horizontal pipe should ≤2 / 1000; detection method with a spirit level.
3, a cross between a parallel or piping, there should be more than 10mm gap.
4, configure the pipeline must make hydraulic valves, piping and other components handling, easy maintenance. Any component or piping system should be able to freely removable without affecting the other components.
5, when the pipe so that the pipe must have a certain degree of anti-vibration and rigid capacity. Properly configured pipe clamps and pipe supports. Bent pipe bracket or pipe clamps should be located near the starting point of inflection. Not with a stent or conduit pipe clamps welded directly.
6, should not bear the weight of the pipe by the hydraulic valves, hydraulic pumps and other hydraulic components and accessories; nor shall a heavier element weight bearing pipes.
7, a longer pipeline must consider effective measures to prevent temperature changes caused by stress telescopic tube.
8, the pipe material used must have a clear basis of raw materials, for unknown pipe materials are not allowed.
9, the hydraulic system in the available wheel 50mm diameter tubes following cutting machine. 50mm diameter pipe above general machining methods should be used to cut. As with gas cutting, machining methods must be used due to changes in the car to gas cutting formed part of the organization, while the car out of the welding groove. In addition to the return line, the pressure pipe is not permitted by the squeeze roller cutter cutting. Pipe cutting surface must be flat, deburring, descaling, slag and so on. Cut surface should be perpendicular to the tube axis.
