The working pressure of conical sealed welded pipe joint can reach 31.5MPa, and the working temperature is 25 ~ 80 ℃. It is suitable for oil pipeline system. The basic principle of two-way hydraulic press is that the oil pump transfers the hydraulic oil to the integrated cartridge valve block, and the hydraulic oil is distributed to the upper or lower chamber of the cylinder through each check valve and relief valve. Under the action of high pressure oil, the cylinder moves. Hydraulic press is the use of liquid to transfer pressure equipment. Fast hydraulic press is generally composed of the machine (main engine), power system and hydraulic control system. Hydraulic press classification valve hydraulic press, liquid hydraulic press, engineering hydraulic press. The function of the working medium used in the 300t four-column hydraulic press is not only to transfer pressure, but also to ensure that the working parts of the machine work sensitive, reliable, long life and less leakage. 315t hydraulic press A machine that uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing process and pressing forming process, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, pressing and so on.
Hydraulic press screw on the hose reusable hose joint permanent connection hose joint is cold extruded to the hose, this joint is generally lower than the reusable joint cost, and the hose assembly workload is small; However, it can only be used once. When the hose fails, the connector is discarded along with the hose. Working pressure is related to hose structure and diameter. Suitable for oil, water, gas medium pipeline system. Medium temperature is 40~ 100°C.
