Hydraulic jacks are used in the process of prestressed steel construction is very much, so the different varieties of hydraulic jacks in principle is not consistent? I would like to introduce the difference and contact between hydraulic jack and screw jack in principle.

First of all, we talk about the working principle of the hydraulic jack.

Hydraulic transmission system, based on the principle of Zui basically is PASCAL's principle, that is, in every region of the liquid is consistent, gas pressure, the stability of the system, a relatively small piston rod above increased work pressure is relatively small, and increase the burden of large piston rod is very large, it can maintain the stationary liquid. Therefore, according to the liquid transfer, the difference of working pressure at different ends can be obtained, so that a change can be achieved. Hydraulic jacks are widely used in this principle to achieve the transmission of force.

Second, let's take a look at the working principle of the screw jack.

The mechanical principle of the screw jack is: the previous double rotation rocker, pull the claws to promote the ratchet gap rotation, small bevel gear to push the big bevel gear, so that the walking screw rotation, and then adjust the specification of the sleeve to be lifted or reduced, and do lifting lifting resistance. But not as simple as a hydraulic jack.

Everyone in the engineering construction process as far as possible according to their own needs to choose the appropriate type and model specifications of hydraulic jacks, which is conducive to your more convenient, efficient and better engineering construction work! A large number of news and information warmly welcome timely care for you!

What are the differences and connections between hydraulic jacks and screw jacks in principle?
