The working principle of the hydraulic press machine
Posted by gldma on September 8th, 2017
The basic principle of four pillar hydraulic press machine is the oil pump to delivery the hydraulic oil to the integrated cartridge valve block, the hydraulic oil will be distributed to the upper or lower chamber through the one-way valve and the relief valve, the cylinder will move under the action of high pressure oil.
The four column hydraulic press machine is the device to use of liquid to transmit the pressure. The liquid follows the Pascal's law when the fluid is delivered in a closed container. The hydraulic drive system of the four-column hydraulic press consists of the power system, the control system, the implementing system, the auxiliary system and the working medium.
The power system is usually adopt oil pump as power system. In order to meet the requirements of the speed of the implementing system, the machine use one or several oil pumps:
1. Low pressure (oil pressure less than 2.5MP) use gear pump;
2. Medium pressure (oil pressure less than 6.3MP) use vane pump;
3. High pressure (oil pressure less than 32.0MP) use piston pump.
Pressure processing and forming of various plastic materials, such as the extrusion, bending, drawing and cold forming of stainless steel plates, as well as the pressing of powder products, grinding wheels, bake lite and resin thermo setting products.
In nowadays, the hydraulic press machine, especially the 4 column hydraulic press machine plays a very important role in the industry production, so choose a professional sheet metal cnc machine manufacturer is a crucial factor to the machine quality.
The hydraulic press machine applied areas:
1. To adapt to various models of anti-theft door molding, pressure side, embossing and other parts.
2. Suitable for pressing covers, size elbow, pipe and other processes.
3. large cars, agricultural car covers and other parts.
4. boiler head, liquefier tank, stainless steel sink, bath and so on.
5. Ships, aviation, aerospace and other areas.
