Let's talk about the inspection items in the maintenance process of single-column hydraulic press. In this way, part of the oil is returned to the tank under the action of potential energy. When the reversing valve is reversed, one cavity of the hydraulic cylinder is filled with pressure oil, and the other cavity of the hydraulic cylinder moves forward due to no back pressure, making the initial speed unstable.

Impactsingle column hydraulic pressWhat are the factors of speed stability?

1. Insingle column hydraulic pressIn the hydraulic system of, when the three-position four-way reversing valve is in the middle position, the oil circuit leading to the hydraulic cylinder is blocked, and the two chambers of the hydraulic cylinder communicate with each other and return to the oil circuit. In this way, part of the oil is returned to the oil tank under the action of potential energy. When the reversing valve is reversed, one cavity of the hydraulic cylinder is filled with pressure oil, and the other cavity of the hydraulic cylinder moves forward due to no back pressure, making the initial speed unstable.

2. Double plunger hydraulic cylindersingle column hydraulic press, Because the leakage of the two chambers is not equal, the frictional resistance of the reciprocating motion is different, and the speed will be unstable.

  3.single column hydraulic pressThe hydraulic system planning is not perfect, the component selection is not matched, the passage and blockage time are saved, the internal and external leakage of the system is serious, the oil enters too much air, and the friction resistance changes, which will also cause the actuator to be unstable at low speed or even crawling.

impossible to usesingle column hydraulic press, but can't repair, we can pass the inspectionsingle column hydraulic pressI believe many friends are very concerned about this problem, but what are the specific checks?

1. External Inspection

Clean the outside of the machine tool, check whether the screws are loose, whether the parts are safe, whether there are cracks or deformation, and the length of the safety signs on the fuselage should not be less than 30cm.

Inspection of 2. clutch device

 

Check the clutch during operation to see the wear of the wave teeth. If it is worn by 1/3, replace it.

3. commissioning inspection

When the machine tool rotates, we should check whether there is air leakage, whether the machine has abnormal vibration and lubrication.

Inspection and adjustment of 4. forging parts

During the pressure test, we can use a relatively high pressure to detect the stroke of the piston. There should be no leakage in the oil circuit. After the pressure is removed, the pressure gauge will return to 0. At this time, the parts are not damaged.

Inspection of 5. input devices

Check the conveyor chain one by one. If there is serious wear and deformation, we have to replace it. The tension of the feed chain must be consistent so that the chain length can slightly touch the bottom plate.

These checks are very useful. If you don't believe me, you can try them. Good things should be shared with everyone. I hope they can help everyone.

Well, Xiao Bian will introduce it to you today. I hope the above explanation will be helpful to you. If you need a purchase order injection hydraulic press, you can consult our manufacturer. Our products will not disappoint you.
