Hydraulic pipe type of hydraulic press introduction machine selection

The hydraulic pipe of the hydraulic press is an important component of the hydraulic system as the conduction of the working oil, and the system transmits the oil through the hydraulic pipe to complete the pressing work. So if the hydraulic pipe is not designed and installed properly, it will lead to vibration, noise, heat and other bad conditions, although the other components are good, it will also cause. And it will stop the hydraulic press from working. So how do we correctly choose the type of hydraulic pipe of the hydraulic press? And choose one that can maximize the efficiency of the hydraulic press? Here is a brief introduction to the types and choices of hydraulic pipes for hydraulic presses.

First, the steel pipe is characterized by high pressure resistance, small deformation, oil resistance, corrosion resistance, low price, not easy to bend during assembly, and can maintain its original shape for a long time after assembly. It is often used as a pressure pipe where it is convenient to disassemble and assemble. Medium and high pressure hydraulic press systems commonly used cold-drawn seamless steel pipes, low pressure systems, oil absorption and return pipelines allow the use of slotted steel pipes.

Second, the copper pipe is characterized by easy bending and forming, easy installation, smooth inner wall, small friction resistance, but low pressure resistance, weak vibration resistance, easy to oxidize the oil, and the price of copper is more expensive, so try not to use or use less. Usually limited to small diameter tubing used as gauges.

Third, nylon tube is characterized by milky translucent, can observe the flow of oil, after heating can be arbitrarily bent and flaring, after cooling set. It is often used in medium and low pressure hydraulic press systems.

Four, plastic pipe oil resistance, low price, easy assembly, but low pressure resistance, long-term use will age. Generally only used as a return oil line.

Fifth, the rubber hose has winding, vibration absorption and noise reduction, but the price is high and the life is short. It is often used as a connection of parts in relative motion. There are two kinds of high pressure and low pressure rubber hose, high pressure pipe with steel wire oil resistant rubber, steel wire cross-braided and wound two kinds, generally 1-3 layers, the more the number of steel wire layers, the higher the pressure resistance; The low pressure rubber hose is made of oil resistant rubber with canvas and is used as the return line.
