A secondary steering pump system (100) includes a secondary steering pump (108), a bypass valve (110) having: a first bypass position (126) configured for fluid communication of the secondary steering pump (108) with a hydraulic tank (104); and a second use/test position (128) configured for fluid communication of the secondary steering pump (108) with the steering control circuit (106). The system also includes a solenoid valve (112) configured for actuation by a solenoid (146) and for selectively actuating the bypass valve (110) from a first position (126) to a second position (128). The system (100) also includes a pressure sensor (114) configured to sense a pressure in the system (100).
次转向泵系统(100)包括次转向泵(108)、旁路阀(110),所述旁路阀具有:第一旁路位置(126),其被配置成用于使所述次转向泵(108)与液压储罐(104)流体连通;以及第二使用/测试位置(128),其被配置成用于使所述次转向泵(108)与转向控制回路(106)流体连通。所述系统也包括螺线管阀(112),所述螺线管阀被配置成用于由螺线管(146)致动以及用于选择性地将所述旁路阀(110)从第一位置(126)致动到第二位置(128)。所述系统(100)也包括压力传感器(114),所述压力传感器被配置成用于感测所述系统(100)中的压力。
