When multiple hydraulic jacks are required to lift at the same time, in addition to correctly placing the jacks, multiple top diverter valves should be used. Therefore, through the transmission of liquid, different pressures on different ends can be obtained, thus achieving the goal of transformation. As long as different scholars have different definitions of corporate social responsibility, the standards used in measuring the level of corporate social responsibility vary, and there are also differences in data and sample selection. Therefore, different conclusions have been drawn when analyzing the relationship between corporate social responsibility and corporate performance.
Users should never exceed the rated stroke when using it to avoid damaging the jack. If several hydraulic jacks are required to lift at the same time, in addition to correctly placing the jacks, multiple top diverter valves should be used, and the load of each jack should be balanced, paying attention to maintaining synchronous lifting speed. It is also necessary to consider the possibility of the ground sinking due to uneven weight, in order to prevent danger caused by tilting of the lifted object. What is the specific usage method for this manual hydraulic jack? Let's take a specific look below. Check whether all parts are normal before use. If you need to support heavy objects for a long time, please use CLL self-locking jack
This hydraulic jack is a spring reset structure that can be quickly removed after lifting, but the connected hose cannot be used to pull the jack. The seven precautions and tips for using an electric jack are revealed. When using it, first connect the quick connector of the manual pump to the top, select a suitable position, and tighten the oil drain screw on the oil pump to start working. To lower the piston rod, loosen the manual oil pump handwheel slightly in a counterclockwise direction, unload the oil cylinder, and gradually lower the piston rod. Otherwise, excessive descent speed will create danger.
Due to the small lifting stroke of hydraulic jacks, the most basic principle based on which hydraulic transmission of jacks is based is the Pascal principle, which means that the pressure of the liquid is consistent everywhere. In a balanced system, the pressure applied on the smaller piston is relatively small, while the pressure applied on the larger piston is also relatively large, which can keep the liquid stationary. Due to the small lifting stroke of the hydraulic jack, users should never exceed the rated stroke when using it to avoid damaging the jack.
