Hydraulic machine crawling has great harm. It destroys the working surface quality and processing precision of hydraulic equipment, reduces the service life of hydraulic machine tools and tools, and even causes waste and accidents, so it must be eliminated. So what are the reasons for the hydraulic machine to crawl? The Hydraulic Press Exporter will come to tell you.

Actuators of hydraulic machine equipment often require very low speeds, such as a few millimeters per minute or even less than 1 mm or a few revolutions per minute. At this time, there will often be obvious speed unevenness, intermittent time-shifting, slow-moving, slow-moving, one-hop-and-stop phenomenon, and the phenomenon of hydraulic machine becomes crawling, that is, the problem of low-speed stability. The lower speed at which no creep occurs, called the critical speed of motion stability.

The same is crawling, the fault phenomenon is different: regular crawling, irregular crawling; some crawling irregularly and with large amplitude; some crawling at very low speed. There are different reasons for the crawling of these different phenomena: some are mainly mechanical reasons, some are mainly hydraulic, some are mainly caused by oil entering the air, and some are poorly lubricated. The reason is mainly. Maintenance and operation of the hydraulic equipment of the hydraulic machine, maintenance personnel must continue to summarize and quickly identify the cause of the crawl and eliminate it. Solve the problem of Hydraulic Press Machine crawling from the following aspects. Focus on solving the frictional state of moving parts and the balance of machine movement:

Hydraulic Press Machine

1) The guide rail has poor precision and the guide rail surface is seriously distorted.

2) There are rust spots on the rail surface.

3) The guide plate of the guide rail is adjusted too tightly, and the dynamic and static friction factors of the guide rail auxiliary material are greatly different.

4) The guide rail is not well studied, the number of points is not enough, and the points are not uniform.

5) The oil groove opened on the guide rail is not good, the depth is too shallow, it has been worn away during operation, the oil groove is not uniform, and the oil groove length is too short.

6) Hydraulic equipment of the new hydraulic press, the guide rails are not running.

7) The hydraulic cylinder shaft line on the hydraulic machine is not parallel to the guide rail.

8) Corrosion and strain in the trapped section of the hydraulic cylinder block on the hydraulic machine.

9) The hydraulic cylinder block, piston rod and piston on the hydraulic machine have poor precision.

10) The hydraulic cylinder on the hydraulic machine and the installation accuracy are poor, and the coaxiality of the piston, the piston rod, the cylinder hole and the cylinder head hole are poor.

11) The hydraulic cylinder piston or cylinder head seal is too tight, blocked or too loose.

12) The downtime is too long, and the moisture in the oil causes some parts to rust.

13) The hydrostatic guide rail is blocked and the guide rail is cut off.

The above is the reason why the hydraulic machine is crawling and crawling. I hope that when you use the hydraulic press, you should check it in time to see if it is due to the above situation, and then prescribe the right medicine.
