The Operation Of A Hydraulic Press

  • A hydraulic press is a device press using a hydraulic cylinder with a piston to produce a constant compressive force against an object. It was first called a Bramah press after its inventor, Joseph Bramah of England. He patented and was first issued a patent for this press in 1795. The first of which can still be found in use today.

    Today hydraulic presses are used in a wide variety of industries, including the ceramic industry. Ceramics is a category of materials that requires a lot of press pressure in order to form thinner than normal parts. As a result, these types of presses have become very reliable and durable. Their reliability makes them ideal for use in high-impact areas like the ceramics processing plants and smelters.

    A four column hydraulic press has four columns or piston units that move up and down along a column. They can be designed to accommodate different press sizes, including a small, thin eight-inch high-pressure cylinder. Hydraulic press compressors usually come complete with a pump, air release valve, piston, cylinder, and various hydraulic parts. Most models have a direct-vent duct system, but some models may also have a vented header.

    The hydraulic press design is very straightforward. The compressed air in the cylinder forces the Tonnage into the feed roller. When the roller reaches its maximum height, the air is released and the material is pushed up through the hydraulic cylinder, forcing the Tonnage further up. As the rollers go up, they push the material up into the work chamber where it undergoes compression to achieve the working pressure. When the rollers are at their lowest point, they compress the materials back down, forming a decrease in the working pressure of the hydraulic cylinder.
