What is the cause of block action of four-column hydraulic press

When the four-column hydraulic press moves slowly and is not flexible, it is necessary to distinguish it from crawling information. If the hydraulic cylinder action command is sent out, the hydraulic cylinder can not immediately start to operate, stay for a period of time before it starts to operate, or when it moves, the action is not regular at all, then this is what we often say, the four-column hydraulic press action block problem. So today, Jianlong Industrial Machinery will take you to understand why there is a block and what the reason is.

The internal of the hydraulic cylinder in the four-column hydraulic press is blocked by air, but it can be exhausted, check the parts of the piston rod complex movement, the sealing ring, and replace the sealing ring if the air is inhaled

Second, the rubber hose inner layer of the four-column hydraulic press is stripped, which also leads to the blocking of the oil circuit, resulting in the irregular action of the hydraulic cylinder, and only need to replace the new rubber hose, but we should pay attention to the point that when the hydraulic cylinder is subjected to a certain lateral load, it will also cause block

Third, the operation of the hydraulic pump of the hydraulic press is irregular, and the rotation is blocked. This mild phenomenon is to be excluded according to the specific type of the hydraulic pump, and it is also to avoid the error of the method leading to greater failure

Fourth, if the piston speed of the four-column hydraulic press is very high, the steel ball of the check valve will also move, resulting in the blockage of the valve hole, resulting in the irregular operation of the hydraulic cylinder, in this case, the steel ball will be replaced with a guide cone valve load spool

Fifth, then the last is a hydraulic cylinder with a buffer device, when the reverse start, the oil pressure will appear the piston temporarily stop or regress, but because the hole of the check valve is too small, the amount of oil entering the buffer is very small, and even the phenomenon of vacuum will appear, there will be an appeal, but it is also quite simple to deal with, only need to increase the hole of the check valve

Then the above is the reason why the four-column hydraulic press is blocked, and finally, when we buy the four-column hydraulic press, we must choose to purchase it in line with the scale requirements of the project.
