2) Feature: J28 Stiffener plate element straightening machine is the large model of its standard product group, for producing large section beams used in heavy duty port machinery and or hoisting machinery; 

3) Topics Covered: In the previous section of J20 Rib plate element straightening machine, we introduced structure and main components of the equipment. In this product section, we will go on to have detailed discussion on hydraulic system, which is the key unit of this heavy machinery.

   1. Hydraulic System of J Series (Including J28) Stiffener plate straightening machine for Large Section Beam:

 1) Purpose of the Ribbed Plate Element Straightening Machine: 

 a) Due to the large tonnage force required, straightening process is driven with oil cylinders;

 b) Hence, hydraulic system is of vital importance for normal and high standard working of the machine;

   2) Specialty of the Ribbed Plate Element Straightening Machine: 

  a) It mainly includes oil cylinders and oil pump station. Oil cylinders are of large scale ones with high

  pressure, featuring in heavy force/ tight sealing/ No leakage even after long time use;

  b) There is bi-directional interlock unit in its pipeline, ensuring sufficient pushing force with self-lock performance of the Ribbed Plate Element Straightening Machine;

    3) Strong Points of the Rib Plate Element Straightening Machine:

    a) Multiple cylinders of this Stiffener Plate Straightening machine work in linkage;

    b) Synchronous capability of oil pipeline is reliable;

    c) Oil pipeline is arranged in floor, making plain/ reasonable layout of good appearance;

    d) Critical components such as main valve are all purchased from famous and long standing suppliers,  guaranteeing dependable performance, keeping minimum maintenance time of this Ribbed Plate Straightening Machine;

     4) Precision and Safety of the Rib Plate Element Straightening Machine:

     a) Secure and precise running of hydraulic system is essential for persistent and high quality delivery of the Ribbed Plate Element Straightening Machine;

     b) Hydraulic pump station and its control pipeline are of independent type; Its control valves are installed in split type based on its working position; The system has overloading protection function;

    c) Both the infeed and outfeed pipeline of hydraulic pump station of the Ribbed Plate Element Straightening Machine have filtering unit, with filtering precision up to 20μm;

    d) There are level detecting unit inside both top and bottom extreme positions of oil tank;

    e) Besides, the oil tank has Oil temperature checking unit/ Oil heating unit/ Oil cooling unit, as well as overload protection function in the Ribbed Plate Element Straightening Machine;

    f) Hydraulic system of this Stiffener Plate Straightening Machine is equipped with manual oil unloading valve. It can make the overall oil pipeline returned to normal condition in case contingency happens; 

5) Based on introduction on Structure/Main components/ Working principle/ Hydraulic system of the Rib Plate Element Straightening Machine in the previous and this product sections, we will discuss its operation in the next product section;

6) Related Equipment with Rib Plate Element Straightening Machine:

a)  JF series Sheet Metal Steel Plate Straightening Machine after butt joint welding;
