Featuresedit
1. The single-arm hydraulic press has the characteristics of good structural rigidity, good guiding performance and fast speed.
2. The convenient manual adjustment mechanism can adjust the indenter or the upper worktable to press at any position in the stroke, and can also adjust the length of fast forward and work progress arbitrarily within the design stroke;
3.l The solid open structure with integral welding can keep the body rigid enough while having the most convenient operating space.
Working medium editing
The function of the working medium used in the single-arm hydraulic press is not only to transmit the pressure, but also to ensure that the working parts of the machine are sensitive, reliable, long-lived and less leaking. The basic requirements of hydraulic press for working medium are: ① suitable fluidity and low compressibility to improve transmission efficiency; ② anti-corrosion; ③ good lubrication performance; ④ easy to seal; ⑤ stable performance, long-term work Without deterioration. The hydraulic press initially uses water as the working medium, and later it is changed to an emulsion made by adding a small amount of emulsified oil to the water to increase lubricity and reduce rust. [1]
In the late 19th century, hydraulic presses using mineral oil as the working medium appeared. The oil has good lubricity, corrosion resistance and moderate viscosity, which is beneficial to improve the performance of the hydraulic press. A new type of water-based emulsion appeared in the second half of the 20th century, and its emulsified form was "water-in-oil" instead of the original "oil-in-water". The outer phase of the "water-in-oil" emulsion is oil. Its lubricity and corrosion resistance are close to oil, and it contains very little oil and is not easy to burn. However, water-based emulsions are more expensive, which limits its promotion.
