Works In principle, the principle is based on hydraulic jacks Pascal principle, namely: the liquid pressure is the same everywhere, so in a balanced system, the jack, the applied pressure above the piston is relatively small relatively small, and Pressure applied to the large piston is relatively large, so that the liquid can remain stationary. So passing through the liquid, it can be different on different ends of the pressure, so that you can achieve the purpose of a transformation. We often see is the use of hydraulic jacks of this principle to achieve transmit force. Maintenance matters: (1) the use of hydraulic jacks to pad the bottom flat, tough. 2) When lifting for a smooth, after jack principle, a little heavy for a check from abnormal conditions, such as no exceptions to proceed to the top. Can not any longer handle or excessive action. (3) does not overload, high. (4) simultaneous operation of several hydraulic jacks, to have someone directing, so lifting or fall simultaneously. (5) should always pay attention to the sealing portion and the portion of the pipe joint when using hydraulic jacks, must ensure their safety and reliability. (6) does not apply to hydraulic jacks acid, alkali or corrosive gases. Hydraulic Lu (Figure), electric jack, jack provided by the Texas Lu of the hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) located in Dezhou City, Shandong Province, seven West Industrial Park. Scraps and development in the wave of market economy, the current Lu hydraulic force has a high profile in the hydraulic machinery and parts, and enjoy a good reputation. Hydraulic Lu made the whole network business alliance certification, marking our service and management level has reached a new height. Lu Hydraulic staff willing to work with all people of insight and common development, for a better future.
