Hydraulic equipment piping nondefective, can be seen at work for some time, the prosecution is not a leak, the pipe is not loose.
Attention should be paid within three months of work (11) The new machine work
During the period the new machine work, the work should grasp the view, such as maintenance parts, screws are not loose, oil is not there does not rise to normal hydraulic oil
is not quickly deteriorate to view the condition of use is not consistent with the provisions Wait.
Pump
: Replace the pump shaft seal qualification.
Joked the hydraulic system of the three ills: "fever, diarrhea with Joseph"
?
????Hydraulic fittings often used this piece for you, be sure to know what the three ills of the hydraulic system? Not that heat, vibration, leak it? Yes, that's right! But
some industry veterans did so nicknamed the hydraulic system of the three ills ----- "fever, diarrhea with Joseph," Hey, you will not laugh a earthshaking listened to it?
?
A fever
As a result of the flow rate of the different parts of the force-transmitting force medium (hydraulic oil) present in the flow process, resulting in the liquid inside certain
internal friction, there is also friction between the liquid and the pipe wall, these are the result of hydraulic oil temperature the main reason. Temperature increase will cause internal and
external leakage, reduce its mechanical efficiency. At the same time due to the higher temperature, hydraulic oil expansion will occur, resulting in compression increases, the control action
can not very well delivered.
?
What is the solution? ------ Fever is an inherent feature of every mechanical operation of the hydraulic pump station system can not be avoided, it can not be eliminated but it
can minimize: Use good quality hydraulic oil, hydraulic piping arrangement should be secluded Free The emergence of the elbow, using high-quality tubing and fittings, hydraulic valve.
?
Second, vibration
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.
