Many people are asking the difference between hydraulic press and hydraulic press? Today, the editor of Voda will give you an in-depth explanation.

Hydraulic press is a machine that uses liquid as working medium and is made according to Pascal principle to transfer energy to realize various processes. It is a machine that uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. It is commonly used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, press fitting and so on.

According to different working media, hydraulic press can be divided into hydraulic press and hydraulic press. The hydraulic press is the one with water-based liquid as the working medium, and the hydraulic press is the one with oil as the working medium;

Most hydraulic presses for forging are hydraulic presses with high tonnage. Large forging hydraulic presses usually have high pressure (about 35 MPa), and sometimes they also use ultra-high pressure above 100 MPa. The working pressure of the hydraulic press is generally 6~25 MPa, and the tonnage of the hydraulic press is generally lower than that of the hydraulic press.

The first hydraulic presses were all hydraulic presses: in 1795, British J. Bramer invented the hydraulic press based on Pascal principle, which was used to pack and press vegetable oil. In the mid-19th century, England began to use hydraulic presses for forging, and hydraulic presses gradually replaced super large steam hammers. By the end of the 19th century, 126000 kN free forging hydraulic press was made in the United States... Later, people found in practice that the performance of hydraulic oil was much better than that of water. The 46 # high-pressure ashless anti-wear hydraulic oil originally supplied by Shandong Voda Heavy Industry not only had proper viscosity and good sealing effect, but also played a very good role in lubricating the interior of the hydraulic system. The hydraulic precision parts would not rust under the immersion of hydraulic oil for a long time, The service life and performance of the hydraulic system are improved, and the performance of water with additives is not as good as that of oil. In addition, the compression ratio of hydraulic oil is smaller than that of water, and the working accuracy is high, so the stability is strong. At present, the presses used in the market are basically hydraulic presses, which are commonly referred to as hydraulic presses.

To sum up, if there is no specific reference, the hydraulic press is usually the hydraulic press.
