Some Known Incorrect Statements About PMC Series Pulse Width Synchronous Lifting System - MR

Summary of the creation The object of this invention is to provide a type of PLC hydraulic proportional simultaneous jacking system for bridge jacking, adopt this system efficiently the existing bridge in city to be changed and to be promoted. Today innovation is that the technical plan that its technical problem of service embraces is, A PLC hydraulic proportional synchronous jacking system for bridge jacking, comprises hydraulic jacking system, discovers sensor-based system and computer control system, wherein: Hydraulic jacking system, comprises the many groups hydraulic jack for jacking bridge, organizes hydraulic jack more and links hydraulic power unit, is also supplied with pressure sensor on hydraulic jack; Find sensor-based system, consist of for detection of the stay wire displacement sensor of bridge jacking displacement and the pressure sensing unit on hydraulic jack; Computer control system, makes up that PLC controller also connects a computer console for the PLC controller to pumping plant pipage control signal; Pressure sensor and remain wire displacement sensor are transferred to PLC controller and computer system console by circuit by signal feedback.

PLC synchronous control hydraulic jacks

Explained stay wire displacement sensor is 14. The precision of stay wire displacement sensing unit is 2. 0mm. The development has the advantages that, embrace PLC to manage the jacking speed that hydraulic jack ratio concurrent jacking system is precisely controlled jack, recognize the ratio synchronization of jacking up of bridge.

Getting The ENERPAC EVOB SYNCHRONOUS LIFTING SYSTEM - WHYPS To Work

By hydraulic jack, properly according to the actual loading of bridge, jacking bridge reposefully, the subsidiary tension that jacking procedure Bridge is subject to drops to minimum. In today innovation, hydraulic jack is divided into 16 groups according to distributing position, by 8 pumping station with extra-high voltage, a set of control system, displacement detector etc., type position closed loop with corresponding 14 displacement transducers (stay wire sensor), to control displacement and the mindset of bridge jacking, synchronization accuracy is 2.

The specific personification For technological means, production characteristic that today creation is realized, reach object and impact is easy to comprehend, below in conjunction with diagram and particular personification, more state today creation.  This Is Noteworthy  explained in today embodiment 1. 1 General Requirements Hydraulic system working pressure: 63.
