Talking about the Working Medium of Single-column Hydraulic Press
single column hydraulic pressThe series has separate hydraulic and electrical control systems. Through button centralized control, two molding processes of fixed and static pressure can be realized. It has the functions of pressure marking, stroke, and pressure adjustment.
In addition, the series is also equipped with 4 columns of guide posts, which can improve the accuracy of the product. The copper plating and hard chrome after the posts and piston rods are on fire ensure the wear resistance and high roughness of the surface. The oil pump inlet is equipped with a unique filter Device to ensure the service life of the oil pump and valve. The oil circuit connection adopts imported high-pressure hose, which greatly reduces the noise of the machine. In addition, according to user requirements, imported PLC, grating protection and man-machine interface (touch screen) can also be configured separately. For the special needs of customers, we can specially design and produce to meet the production process needs of customers to the greatest extent.
single column hydraulic pressWhat is the medium of work?
The role of the working medium used in a single-column hydraulic press is not only to transmit pressure, but also to ensure that the working parts of the machine are sensitive, stable, long-lived, and less leakage. The basic requirements for the working medium of a single column hydraulic press are as follows. 1 In order to improve the efficiency of the transmission, there is appropriate mobility and low compressibility. Corrosion can be prevented. It has good lubrication performance. Easily sealed. Stable performance, no deterioration, long-term work. The hydraulic press initially used water as the working medium, and later replaced a small amount of emulsified oil with an emulsion made of water, which improved lubricity and reduced corrosion. In the second half of the 19th century, hydraulic presses with mineral oil as the working medium were introduced. The oil has lubricity, corrosiveness and proper viscosity, which helps to improve the performance of the single column hydraulic press. In the second half of the 20th century, a new water emulsion appeared, and its emulsification form was not the original "water lactation", but "running water". The wound of the "oil cloth water" emulsion is oil, which is close to oil in lubricity and corrosiveness, and has less oil content and is not easy to burn. However, the price of water emulsion is more expensive, which limits its promotion.
The single-column hydraulic press has an independent power mechanism and electrical system. It is centrally controlled by buttons. The working pressure, compression speed, no-load rapid drop and deceleration stroke and range of the machine can be adjusted according to process requirements to complete the ejection process. The ejection process and the stretching process are three process methods, each of which is a fixed pressure, and the correction 2. Single-column hydraulic press has a wide range of versatility, suitable for extrusion, bending, folding, stretching and other plastic materials processing and molding, hydraulic press can also be used for a variety of plastic, powder products pressing molding. The outer edge hydraulic press can also be used for product calibration, extrusion, molding, etc.
