Among some commonly used machinery and equipment, there is a kind of machinery and equipment, which can be said to be widely used, and it is also an important product in the company, which is a four-column hydraulic press. Therefore, it will be the focus of our study below, mainly to understand and master some related knowledge content, and it is not explained before, in order to promote the learning process of this product.
1. Is the four-column hydraulic press the same as the four-column hydraulic press? And, is there a difference between a four-column hydraulic press and a mechanical press?
Four-column hydraulic press and four-column hydraulic press, although the difference between the two is only one word, but in essence, they are not the same, but there is a subordinate relationship, that is, four-column hydraulic press is a kind of four-column hydraulic press. Moreover, the four-column hydraulic press uses oil to transmit pressure, while the four-column hydraulic press can be either oil or water and other substances.
There are definitely differences between the four-column hydraulic press and the mechanical press. Because the four-column hydraulic press is mainly used for pressing and stretching large pieces, while the mechanical press is mainly used for punching.
2. Is the tonnage of the four-column hydraulic press equal to the pressure?
In a four-column hydraulic press, how many tons is it refers to how much pressure the machine equipment can reach, which is a kind of force. And pressure, which is not a force, and its unit is MPa, which is different from the unit of force. Therefore, these are two different concepts that cannot be confused.
3. What are the common faults of the four-column hydraulic press? And, if it's not stressful, what are the specific reasons?
The common faults of four-column hydraulic presses are mainly oil leakage, valve leakage, reversing valve stuck, valve core wear and sealing ring wear and so on. As for the fact that there is no pressure in the four-column hydraulic press, the main reasons are that there is a problem with the oil pump, and there is a problem with the sealing ring in the master cylinder.
