The invention provides a control method of a rotary hydraulic system. The control method comprises the specific steps that S1, an oil tank outputs hydraulic oil to one port of a rotary motor through one of a first oil outlet and a second oil outlet; s2, part of hydraulic oil flows to the control ends of the first reversing valve and the second reversing valve; s3, when the oil pressure of the hydraulic oil is larger than that of the first reversing valve; (1) reversing the first reversing valve to enable the P end of the first reversing valve to be communicated with the A end; (2) the hydraulic oil flows to a first reversing valve through a two-way valve; (3) the hydraulic oil flows to a control port of the two-way valve through the first reversing valve; (4) the two-way valve is opened, and the hydraulic oil flows to the other port of the rotary motor through the two-way valve; s4, when the oil pressure of the hydraulic oil is larger than that of the second reversing valve; (6) reversing the second reversing valve to enable the P end of the second reversing valve to be communicated with the A end; (7) the hydraulic oil flows to a brake valve through the P end and the A end of the second reversing valve; s5, opening a brake valve; the rotary motor steers.
本发明提供一种回转液压系统的控制方法,具体步骤包括:S1油箱通过第一出油口或第二出油口其中一个出油口输出液压油至回转马达的其中一个端口;S2一部分液压油流向第一换向阀和第二换向阀的控制端;S3当液压油的油压大于第一换向阀时;(1)第一换向阀换向,使得第一换向阀的P端连通A端;(2)液压油经过二通阀流向第一换向阀;(3)液压油经过第一换向阀流向二通阀的控制端口;(4)二通阀打开,液压油经过二通阀流向回转马达的另一个端口;S4当液压油的油压大于第二换向阀时;(6)第二换向阀换向,使得第二换向阀的P端连通A端;(7)液压油经过第二换向阀的P端和A端流向刹车阀;S5刹车阀打开;回转马达进行转向。
