The Best Guide To Weighing and Manipulation System for Ship's Hull Sections

So when dividing control location, whether the position of setting up that think about displacement transducer can show the worldwide displacement of this control area objectively. Meanwhile, when displacement transducer establishes, ought to guarantee its verticality, decrease individuals for causing error as far as possible, guarantee the precision of displacement transducer.

Its technical sign sees the list below kind.  RIVERLAKE -YW06 stay wire displacement sensing unit the essential technical indexes Variety ability Resolution ratio Supply voltage Operating temperature level Setup type 1200mm 0. 01mm 24VDC -1560 C Fixed support 3. 3 computer system control system Computer system control system is the core of whole PLC system, it will be processed by the collected data analysis of keeping track of sensor-based system, and the data feedback after a processing is to hydraulic system, by each jack oil pressure of policy of hydraulic system, consequently guarantees entire jack-up system synchronism.

System has been installed ups power, even if accident power-off also can be guaranteed the security of data and engineering. Electric-control system as displayed in Figure 4. 4 jack-up system control concepts The signal of multi-point displacement detection signal and pressure sensing unit is connected in the electric control box of pumping station with extra-high voltage by signal cable television, after signal amplifier enhances, jacking displacement and load tonnage are provided in programmable reasoning controller PLC, the motor of lots of pumps of operation start instruction that PLC sends according to console, drive operation of oil pump, the power oil sources of oil pump is through control valve group, output in external hydraulic jack, hydraulic jack is moved up and down.
