The basic principle is based on the working principle of hydraulic transmission is Pascal principle, that is, the liquid pressure is the same everywhere in Dalian 200 tons of hydraulic jacks, so in a balanced system, the applied pressure above the piston is relatively small small Lanzhou 320 tons hydraulic jacks, and pressure applied to the piston is relatively large, so that the liquid can remain stationary. Therefore, the liquid passing through the hydraulic jacks, you can get different pressures on different ends, so that you can achieve the purpose of a transformation. We are common to the electric hydraulic jack is the use of this principle to achieve transmit force. Electric jack Definition: also known as electro-hydraulic jack, which is a combination of a hydraulic cylinder and electric pump made of, can achieve the top, push, pull various forms of work, extrusion. Xinjiang 200 t hydraulic jack _ Long Hydraulic (certified) _ hydraulic jack provided by the Dezhou City, Long hydraulic equipment factory. Long Dezhou City of hydraulic equipment factory (www.longliyy.com) is an industry leader in Shandong Dezhou, hydraulic equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the long Hydraulic leadership with the staff warmly welcome all inquiries negotiations to create long hydraulic force a better future.
