Purpose:

The prestressed intelligent numerical control tensioning system is suitable for pre tensioning and post tensioning.

characteristic:

It has the characteristics of "force and elongation" double control. It is mainly controlled by tension and assisted by elongation. The control accuracy of tension can reach 1% FS.

It has the functions of manual tensioning and automatic tensioning. Automatic tension, tension automatic grading (10%, 20%, 50%, 100%, automatic or manual over tension) control. After reaching the preset tension of each level, the load or pressure will be maintained automatically according to the preset time. During the tensioning process, the elongation value will be automatically checked to judge whether the tensioning is qualified. The automatic shutdown prompt will be given for the excessive or insufficient elongation, and the automatic or manual tensioning can be made according to the actual tensioning results.

The hydraulic circuit of the system has self-locking function, which can keep the state of oil cylinder unchanged for a long time after stopping oil supply.

The main control station of CNC hydraulic pump station adopts the configuration software system operated by industrial touch screen computer, which has friendly operation interface, convenient use and good man-machine interaction.

The main control station of the numerical control hydraulic pump station, the auxiliary station of the numerical control hydraulic pump station and the data monitoring computer are connected through the wireless network, which is convenient to move on the site.

The system has the characteristics of standardization and integration. The standard main control pump station can be configured with multiple auxiliary pump stations to form a multi-point synchronous tensioning system.

The system can pre-set the tensioning parameters of each hole of the whole beam according to the tensioning sequence before tensioning according to the requirements of tensioning conditions. During tensioning, the system only needs to call out the sequence number and directly press the start key to complete the tensioning with one key, so as to realize intelligent operation.

The system has the function of power-off memory. Even if there is an unexpected power failure during the tensioning process, the data will not be lost. After being powered on again, the system can maintain the state before the power failure and continue to complete the tensioning.

The multi mirror storage technology is used to record the tension data in real time, and the same tension data is stored in the internal storage unit and computer of the touch screen of the console.

The report forms are automatically generated, and it is not necessary to arrange the data by another person. It can be printed at any time by connecting with the printer.
