针对大型工程结构加载试验的需求,研制一种高压重型平面静压支承系统。系统采用4个密封腔的密封结构,应用定比减压阀和偏载自动补偿阀,在保证承载能力的同时使静压支承油腔压力跟踪外负载变化,提高静压支承的油膜刚度,同时实现静压支承系统的抗偏载能力。研制的高压重型平面静压支承已经应用于大型工程结构的加载试验领域。 In response to the needs of large-scale engineering structure loading test, a high-pressure heavy-duty plane static pressure support system is developed. The system uses four sealed chamber seal structure, the application of proportional pressure relief valve and partial load automatic compensation valve, while ensuring the carrying capacity of hydrostatic pressure bearing oil tank pressure to track changes in external load to improve the hydrostatic support film stiffness, at the same time Anti-eccentric load capacity of hydrostatic bearing system. Developed high-pressure heavy-plane hydrostatic support has been applied to large-scale engineering structure of the loading test.
