(6) pay attention to investigate the case of a mechanical action (on the modified pump)
Inappropriate or poor planning of the hydraulic circuit components manufacturing, during the initial application is not easy to find, it should use special care in a variety of conditions showing the action situation.
(7) carefully adjust the valves within
Fully aware of the pressure control valves, flow control valves and directional control valves use, and limit the size of the adjustment required special care, or adjust the fault not only mechanical damage and more of a security threat.
(8) See filter case
Of the loop filter should be removed and cleaned regularly, and see the situation and dirt filter medium adsorbed, analyze quality, quantity and size, so the loop can investigate contamination, even infer the source of contamination sites.
(9) See the timing of hydraulic oil change
Every one or two months view analysis of hydraulic oil deterioration, discoloration and contamination degree of change, in order to ensure the normal hydraulic transmission medium.
(10) the situation carefully leaked pipe part
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.

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.
