The load-sensing pre-valve compensation technology is widely used in the single-pump multi-acting mechanism composite motion circuit. Due to the use of multi-valve inlet valve front compensation, its structure is simple, only need to set a two-way fixed-rate valve, but the flow saturation conditions cannot be automatically adjusted. Through an in-depth theoretical analysis of the anti-saturation mechanism, composition and control strategy principle based on automatic flow reduction (AVR), the AMESim model of the system is established, and the anti-flow-saturation output characteristics of the system are obtained under different operating conditions by numerical simulation means, and the results show that the system can solve the problem of flow-saturation. It provides some technical reference for the design of the load-sensing pre-valve compensation system.
