The analysis shows that the speed adjustment of the separate jack should be carried out loop by loop. When debugging a loop, the rest loops should be closed.

Among them, we learned that when adjusting the speed, the gap of the guide rail and the position accuracy of the moving parts of the jack must be adjusted at the same time, so as not to cause the transmission parts to be too tight and jammed.

Separate jack

As a kind of jack products, the separate jack can be seen in the construction of various industries. In practical applications, it is necessary to adjust the speed of this equipment. So what should we do?

If there is air in the jack, the speed will be unstable. Open the exhaust valve of the jack during the debugging process to remove the air trapped in the jack.

Jacking jack

Jacking jacks can be used to replace tires in automobiles, but many car owners do not pay attention to the correct use of jacking jacks, and there are often unnecessary dangerous problems.
Many car owners will subconsciously arrange the support points at the edge of the vehicle chassis when using the jacking jack.

We can design a scenario for this problem: before raising the car, put a dummy model under the car chassis, Use a model to imitate the environment of changing tires.

If we raise a speciality hydraulic bottle jack , and raise it to the highest position, then the vehicle lifted by the jacking jack will suddenly Falling from the jacking jack will be heavy on the dummy model. This is because as the vehicle continues to rise, the edge of the chassis will be severely deformed and broken by the jacking jack, causing the vehicle to slide down heavily, and the supporting point of the force will also be pushed out by the jacking jack. Groove.
