The hollow hydraulic cylinder has the characteristics of large output force, light weight and long-distance operation. It is equipped with the factory's ultra-high pressure electric oil pump station, which can realize various forms of operation such as jacking, pushing, pulling, and squeezing. The hollow hydraulic cylinder is widely used in construction engineering and shipbuilding, metallurgy, mining, petrochemical, railway engineering, etc. and other industrial jacking, stretching, squeezing and other operations. In recent years, the hollow hydraulic cylinder has been widely used in foundation settlement tests and static piles. Hollow hydraulic cylinder: A hydraulic pump is driven by manpower or electricity and is driven by a hydraulic system, using cylinders or pistons as lifting parts. Hydraulic jacks can be divided into integral type and separate type. The integral pump is integrated with the hydraulic cylinder; the separate pump is separated from the hydraulic cylinder, and the middle is connected with a high-pressure hose. The hydraulic jack has a compact structure, can lift heavy objects steadily, and has high transmission efficiency, so it is widely used; but it is easy to leak oil and is not suitable for long-term support of heavy objects. If self-locking jacks are required for long-term support, screw jacks and hydraulic jacks can be made into multi-stage telescopic types to further reduce the profile height or increase the lifting distance. Features of the single acting hollow hydraulic cylinder:
1. Suitable for all kinds of test and maintenance and applications requiring tension
2. The design of the hollow plunger can be used for both pulling force and thrust force;
3. For models over 20 tons, use nickel-plated movable center tube to increase product life
4. The surface of the paint has stronger corrosion resistance;
5. The outer ring thread makes fixing easy; How to use the double acting hollow hydraulic cylinder:
1. Connect the oil pipe: first check the connection of each component, the quick connector should be inserted firmly, use a manual pump or an electric pump to supply oil to the hydraulic jack, and connect the jack to the pump station through the oil pipe.
2. Strictly abide by the regulations in the main parameters, and remember to not be able to exceed the high and overload, otherwise the lifting height and the lifting tonnage will exceed the specified weight, the top of the cylinder will start to leak oil.
3. Leveling the position: to ensure the level of the bottom surface, while taking into account the soft and hard conditions of the ground, whether it should be lined with tough wood or pads, and whether it is placed stably to prevent heavy objects from sinking or tilting.
