The invention provides an oil pressure controlled rotary hydraulic system which comprises a brake oil way and a brake control oil way, the brake oil way is connected with an oil tank, and the brake control oil way is arranged between the oil tank and the brake oil way; the brake oil way comprises a rotary motor and a brake valve, a first oil outlet and a second oil outlet are formed in the oil inlet end of the oil tank, the first oil outlet is connected with a left-turning port of the rotary motor, the second oil outlet is connected with a right-turning port of the rotary motor, the rotary motor is further connected with the oil return end of the oil tank, the brake valve is arranged on the rotary motor, and the brake valve is connected with the oil return end of the oil tank. The brake valve is connected with a brake control oil way; according to the structure, by arranging the brake control oil way, it is guaranteed that hydraulic oil exists in the hydraulic oil way of the rotary motor when the rotary motor is started, and therefore it is guaranteed that the rotary motor is balanced, and natural rotation is not prone to occurring.

    本发明提供一种油压控制的回转液压系统,包括刹车油路和刹车控制油路,所述刹车油路连接油箱,在油箱与刹车油路之间设有刹车控制油路;所述刹车油路包括回转马达和刹车阀,在油箱的进油端设有第一出油口和第二出油口,所述第一出油口连接回转马达的左转端口,第二出油口连接回转马达的右转端口,所述回转马达还连接油箱的回油端,在回转马达上设有刹车阀,所述刹车阀连接刹车控制油路;上述结构,通过设置刹车控制油路,使得在回转马达启动时保证回转马达的液压油路中有液压油,从而保证回转马达的平衡不容易出现自然转动的问题。
