Our most common examples of such projects is actually cylinder hydraulic cylinders, based on actual investigation found that the hydraulic cylinder output force and the effective area of ??the piston and the pressure is proportional to both sides of the linear motion-type actuator. Hydraulic engineering cylinders are mainly used to support the weight of place will take time, it may still be supported during removal of heavy oil, and safe and reliable. Can be used underwater, single-acting, load retraction, the self-locking nut so that the load more secure, especially in large projects, is easy to operate and control and self-locking jack, designed with safety packing device, built pressure relief valve to prevent overload, to protect the self-locking jack to facilitate safe operation. Connecting the device, using high-pressure hose and nipple connection with the use of fast, quick and overcome the shortcomings of traditional joint oil spill is mainly used for electric power, construction, machinery manufacturing, mining, railway bridges, shipbuilding and other industries equipment installation Removing from the top job. Here we take a look at the advantages of hydraulic engineering cylinder: 1, due to the pneumatic system uses pressure is generally in the range of 0.2-1.0Mpa, so the cylinder is not as dynamic elements to use power, hydraulic cylinders can be done relatively high power components to use, or use the fuel tank system. 2, speaking of air from the medium is inexhaustible, no cost and supply difficulties, the gas will be used directly into the atmosphere, convenient, and do not pollute the hydraulic oil. 3, the air viscosity is small, the resistance is less than the hydraulic oil. 4, but because the air is much larger than the compression rate of hydraulic oil, so it's working on stability and response than end up.
