The specific embodiment
Like Fig. 1-shown in Figure 4; Conticaster ejection hydraulic system is made up of constant voltage control No Load Start formula power source 1, oily temperature control heating system 6, liquid level control oil tank system 7, oily temperature control circulation cold filtration system 8, unusual sender oil return filtration system 9, pressure sensing control device 10, turn over cooling bed valve platform 3, tilting gear valve platform 4 and accumulator group 2, and constant voltage is controlled No Load Start formula power source 1 and is connected with accumulator group 2; Turn over cooling bed valve platform 3 is connected with tilting gear valve platform 4; Oil temperature control heating system 6 is connected with liquid level control oil tank system 7, and oily temperature control circulation cold filtration system 8, unusual sender oil return filtration system 9 are controlled oil tank system 7 with liquid level respectively and be connected, and pressure sensing control device 10 is controlled No Load Start formula power source 1 with constant voltage and is connected; Constant voltage control No Load Start formula power source is made up of 3 pump groups; Turn over cooling bed valve platform 3 is made up of cold bed lifting loop and the traversing loop of cold bed, and tilting gear valve platform 4 is made up of four stream tilting gear loops, and accumulator group 2 is made up of four groups of accumulators and control valve group; The Hydraulic Station part; Constant voltage control No Load Start formula power source according to load set pressure, is that system provides constant compression force according to system's needs.If constant pressure pump is in case appearance is unusual, electromagnetic relief valve can play the safeguard protection effect to equipment.Electromagnetic relief valve can be controlled the motor No Load Start in addition; So both reduced the primary election power of motor, played energy-conservation effect, when having reduced electric motor starting greatly again to the impact of electrical network; Improve the security of electrical network, also reduced rate of breakdown simultaneously.Hydraulic Station has had the oily temperature control system of Automatic Control, can be according to system's needs, and system is heated or cools off.Circulated filter system can guarantee the cleannes of system media, and system can normally be worked on request, and the setting through-flow, pressure of the liquid level of fuel tank, filter can be through PLC control.
Turn over cooling bed valve platform, the stronger inserted valve of conveyance capacity has been selected in cold bed lifting loop for use, has satisfied the requirement of the big flow of system.Selected for use the higher tetrad syncmotor of synchronization accuracy to control the synchronization lifting of four elevating rams in the loop; And add the rectification speed-regulating function and can compensate synchronous error, make synchronization accuracy higher, the high accuracy proportional valve control is adopted in the traversing loop of cold bed; The speed of cold bed in traversing process is become at random; During traversing breasting the tape, also can cushion control, more flat when making cold bed traversing.
