The invention discloses a rotary buffering system which comprises a rotary buffering valve, a pilot pressure detection device and a rotary motor, and the rotary buffering valve controls the rotary motor to reverse and rotate. A main reversing valve core, a first main overflow valve and a second main overflow valve are arranged in a valve body of the rotary cushion valve, a pressure oil port of the first main overflow valve is communicated with a port A of the valve body, and a pressure oil port of the second main overflow valve is communicated with a port B of the valve body; a first oil recharging one-way valve and a second oil recharging one-way valve are further arranged in the rotary cushion valve, and oil inlets of the first oil recharging one-way valve and the second oil recharging one-way valve are communicated with the T port of the valve body; a shuttle valve and a rotary buffer oil duct are further arranged in the valve body of the rotary buffer valve; the rotary buffer oil duct is divided into a low-pressure buffer oil duct and a high-pressure buffer oil duct; the low-pressure buffering oil channel is provided with a low-pressure buffering damper, and the high-pressure buffering oil channel is provided with a high-pressure buffering damper. According to the invention, the turntable is buffered when different inertia moments are generated at the moment of rotation stop, so that the phenomenon of speed fluctuation in the continuous rotation process of the turntable is avoided.

    本发明公开了一种回转缓冲系统,包括回转缓冲阀、先导压力检测装置和回转马达,回转缓冲阀控制回转马达换向与回转;回转缓冲阀的阀体内设有主换向阀芯、第一主溢流阀和第二主溢流阀,第一主溢流阀的压力油口连通阀体的A口,第二主溢流阀的压力油口连通阀体的B口;回转缓冲阀内还设有第一补油单向阀和第二补油单向阀,第一补油单向阀和第二补油单向阀的进油口与阀体的T口连通;回转缓冲阀的阀体内还设置有梭阀和回转缓冲油道;回转缓冲油道分成低压缓冲油道和高压缓冲油道;低压缓冲油道设有低压缓冲阻尼,高压缓冲油道设有高压缓冲阻尼。本发明使转台在回转停止瞬间产生不同惯性力矩时都得到缓冲,避免了转台持续转动过程中速度波动的现象。
