Hollow plunger hydraulic jack cylinder for sale
Hollow plunger hydraulic jack cylinder is suitable for all kinds of testing, maintenance and application sites that require tension. Double-acting form, can return quickly. Chrome-plated surface and floating center tube extend product life. The hollow plunger allows thrust and pull. The painted surface makes the corrosion resistance stronger. The dust-proof ring reduces pollution and prolongs the life of the hydraulic cylinder. This hollow hydraulic jack cylinder not only has all the functions of a normal jack, but also has a stretching function, and is used for steel cables, cables, and shafts.
How to use hollow plunger hydraulic jack cylinder:
1. Check whether each part is normal before use. Strictly abide by the provisions in the main parameters when using it, and avoid super high and overload, otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the cylinder.
2. If the oil volume of the manual pump body is insufficient, it is necessary to add anti-wear hydraulic oil that should be fully filtered to the pump before it can work. Please refer to the manual of the electric pump for the electric pump.
3. The center of gravity of the heavy object should be moderate, and the hollow hydraulic jack cylinder should be selected reasonably. The bottom surface should be leveled. At the same time, the soft and hard conditions of the ground should be considered, whether it should be lined with tough wood, and whether it is placed smoothly to avoid sinking or tilting of the load.
4. After the hollow hydraulic jack cylinder lifts up the heavy object, the support should be used to support the heavy object in time. It is forbidden to use the jack as a support. If you need to support heavy objects for a long time, please use CLL self-locking jacks. When several jacks need to be lifted at the same time, in addition to the correct placement of the hollow hydraulic jack cylinder, a multi-jack diverter valve should be used, and the load of each jack should be balanced, paying attention to keeping the lifting speed synchronized. It must also be considered that the ground may sink due to uneven weight to prevent the weight being lifted from tilting and causing danger.
5. When using, first connect the quick connector of the hand pump with the top, then select the position, and tighten the oil drain screw on the oil pump to work. To lower the piston rod, loosen the hand wheel of the manual oil pump slightly in a counterclockwise direction, unload the oil cylinder, and the piston rod will gradually descend. Otherwise, the falling speed will be dangerous.
6. The hydraulic jack cylinder for sale is a spring reset structure, which can be quickly taken out after lifting, but the plunger hydraulic jack cylinder cannot be pulled by the connected hose. Due to the small lifting stroke of the jack, the user must not exceed the rated stroke when using it to avoid damage to the jack. Avoid severe vibration of the jack during use.
7. Not suitable for use in workplaces with acid, alkali, corrosive gas. Users should check and maintain regularly according to the usage.
