1000ton hydraulic jack working principle

2018-07-27 14:45:57

The most basic principle based on hydraulic transmission is the pascal principle. That is to say, the pressures around the liquid are consistent. Thus, in a balanced system, the pressure exerted on the smaller piston is smaller, and the pressure is larger. The pressure exerted on the piston is also relatively large, which keeps the liquid stationary. Therefore, through the transfer of the liquid, different pressures at different ends can be obtained, so that a transformation can be achieved. The hydraulic electric jacks we often use are using this principle to achieve force transmission.

How to use 1000ton hydraulic jack:

1. Check that the parts are normal before use.

2.  The use should strictly abide by the provisions of the main parameters, avoid excessive overload, otherwise when the lifting height or lifting tonnage exceeds the regulations, the top of the electro-hydraulic jack will suffer serious oil leakage.

3.  For electric pump, please refer to the instruction manual of GAODETEC electric pump.

4.  The center of gravity of the heavy object should be moderately selected. The focus of the electro-hydraulic jack should be properly selected. The bottom surface should be leveled. At the same time, the soft and hard conditions of the ground should be considered. Whether the tough wood should be padded should be placed smoothly to prevent the load from sinking or tilting.

5.  After the electro-hydraulic jack lifts the heavy object, the support should be used to support the heavy object in time. It is forbidden to use the ultra-high pressure large-tonnage electric jack as a support. If you need to support heavy objects for a long time, please choose self-locking jack.

6.  If you need several electro-hydraulic jacks to lift at the same time, please choose the type synchronous jack. In addition to correctly amplifying the tonnage electric jack, you should use multi-top diverter valve, and The load of each large-tonnage electric jack should be balanced, keeping in mind that the lifting speed is synchronized. It is also necessary to consider the possibility that the ground may be sunken due to uneven weight, and it is dangerous to prevent the weight from being tilted.

7.  When using, first connect the quick joint of the manual pump to the top, then select the position and screw the oil drain screw on the oil pump to work. To lower the piston rod, the manual oil pump hand wheel is slightly loosened in the counterclockwise direction, the cylinder is unloaded, and the piston rod is gradually lowered. Otherwise the speed of falling too fast will be dangerous.
8.  The electric jack is hydraulically retracted. After lifting, it can be quickly taken out, but the connected hose can not be used to pull the ultra-high pressure large tonnage electric jack.

9.  Do not exceed the rated stroke when using the user to avoid damage to the electro-hydraulic jack.

10.  The 1000ton hydraulic jack should be violently vibrated during use.

11.  It is not suitable for use in workplaces with acid and alkali and corrosive gases.

12.  Users should check and maintain regularly according to the usage.
