The specific embodiment
Such as Fig. 1-shown in Figure 4, knockout hydraulic system for continuous casting machine, by constant voltage control No Load Start formula power source 1, oil temperature control heating system 6, liquid level control oil tank system 7, oil temperature controlled circulation cold filtration system 8, unusual sender oil return filter system 9, pressure sensing control device 10, turn over cooling bed valve platform 3, tilting gear valve platform 4 and Accumulator arrangements 2 form, constant voltage control No Load Start formula power source 1 is connected with Accumulator arrangements 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, oil temperature controlled circulation cold filtration system 8, unusual sender oil return filter system 9 is connected with liquid level control oil tank system 7 respectively, pressure sensing control device 10 is connected with constant voltage control No Load Start formula power source 1, constant voltage control No Load Start formula power source is made of 3 pump groups, turn over cooling bed valve platform 3 is made of cold bed lifting loop and the traversing loop of cold bed, tilting gear valve platform 4 is made of four stream tilting gear loops, Accumulator arrangements 2 is made 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, provide constant pressure according to system's needs for system.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 startup in addition, so both reduced the primary election power of motor, played energy-conservation effect, when having reduced greatly electric motor starting again to the impact of electrical network, improve the security of electrical network, also reduced simultaneously the fault rate of equipment.Hydraulic Station has had the oil 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 controlled by PLC.
Turn over cooling bed valve platform, the stronger inserted valve of conveyance capacity has been selected in cold bed lifting loop, has satisfied the requirement of the large flow of system.Selected the higher tetrad syncmotor of synchronization accuracy to control the synchronization lifting of four elevating rams in the loop, and adding rectification speed-regulating function can compensate synchronous error, so that synchronization accuracy is higher, the high accuracy proportional valve control is adopted in the traversing loop of cold bed, make the speed changing of cold bed in traversing process, traversing when the terminal point, also can cushion control, more flat when making cold bed traversing.
