Welding hydraulic bottle jack is an excellent jack that has welding structure, forging base, the built-in pressure regulating valve, one-piece piston rod, piston rod stroke bearing pin spacing section, high frequency quenching pump core.
In principle, the hydraulic jack is based on Pascal principle, that is, the pressure of the liquid is the same everywhere, so in a balanced system, the pressure exerted on the smaller piston is relatively small, and the pressure exerted on the larger piston is also relatively large, which can keep t
