1, self-locking hydraulic jack: stainless steel plunger pump, overflow action limit travel arrangement, torsion spring retracting or load retracting, for long-term support point heavy, it can still be applied to the removal of steam pressure, and can be trusted. Can also be used in the water, that of single or double action load retraction, design with safety testing equipment, embedded discharge pressure valve to avoid load, especially composite material coating to make it stronger corrosion resistance ability to work, and make the actual operation sliding friction is smaller, can withstand the bearing capacity of the partial load of the hydraulic system of rating 5%, nut self-locking make load more security, The outlet has the function of maintaining the self-locking hydraulic jack and limiting the travel arrangement.

2. Single-acting hydraulic jack and double-acting hydraulic jack are actually determined according to the reset method.

Visually, the single-acting hydraulic jack is equipped with a standard connection head, and the double-acting hydraulic jack is equipped with two standard connection heads. Single-acting hydraulic jack reset method is heavy capacity reset, double acting hydraulic jack is hydraulic machine reset.

Heavy power reset: after lifting, must load the constant weight, jack brand clutch on the inside of the cylinder head high toughness torsional spring under tensile resistance, slow drop in blood pressure, finally to reset the hydraulic jack, this method must be reset for a long time, but because only one internal structure and high toughness of the torsional spring traction belt, engineering cost is more cost-effective.

Hydraulic machine reset: that is, the application of hydraulic machine can, the hydraulic cylinder out of the mold again into the cylinder head, generally speaking, the hydraulic cylinder retraction required when the working pressure is half of the lifting. This kind of reset speed is faster, and it is the best choice for the engineering project that must be completed in a short time, because the structure is cumbersome and the project cost is relatively expensive.
