Hydraulic pump system and control device
A hydraulic pump system is provided with: a hydraulic pump capable of changing the discharge flow rate; a regulator device that regulates the discharge flow rate of the hydraulic pump; an operation device having an operation tool; a lock switching input unit for releasing the locked state of the operation tool; an unloading valve for adjusting the discharge pressure of the hydraulic pump by changing the opening area thereof; and a control device for controlling the operation of the unloading valve. The control device reduces the opening area of the unloading valve and increases the discharge pressure of the hydraulic pump when a predetermined operating condition is satisfied, the regulator device increases the discharge flow rate after the control device increases the discharge pressure of the hydraulic pump, and the operating condition includes releasing the locked state of the operation tool through the lock switching input part.
油压泵系统具备：能变更吐出流量的油压泵；调节油压泵的吐出流量的调节器装置；具有操作工具的操作装置；解除操作工具的锁定状态的锁定切换输入部；通过改变其开口面积来调节油压泵的吐出压的卸荷阀；和控制卸荷阀的动作的控制装置；控制装置在满足规定的工作条件时，使卸荷阀的开口面积减少使油压泵的吐出压升压，调节器装置在所述控制装置使所述油压泵的吐出压升压后，使吐出流量增加，工作条件包含通过锁定切换输入部解除操作工具的锁定状态。
