The invention provides a combined oil pump with an electromagnetic reversing valve, which relates to the technical field of transportation and comprises a manual/electromagnetic reversing valve, a manual pump, an electric pump and a handheld switch, the manual pump and the electric pump are integrated, the manual and electromagnetic reversing valve is arranged on the manual pump and is provided with a manual reversing knob, and the handheld switch is arranged on the manual pump. The lifting and descending functions of the cab can be achieved through the handheld switch. Rapid reversing of the handle is achieved by starting the electromagnetic reversing valve, meanwhile, the control circuit is switched on to achieve automatic oil pumping of the electric pump, and therefore overturning of the cab is achieved; the reversing of the electromagnetic valve is realized by the knob switch, and the automatic oil pumping of the electric pump is realized by the starting button; the conditions show that electric reversing of the oil pump is achieved through the handheld switch and the electromagnetic reversing valve; and meanwhile, a manual reversing function is reserved, so that the structure and the operation are more reliable.
本发明提供了一种带电磁阀换向的组合油泵,涉及交通运输技术领域,包括手/电磁换向阀、手动泵、电动泵、手持开关,手动泵和电动泵为一体式,手、电磁换向阀装在手动泵上,同时具备有手动换向旋钮,可以通过手持开关实现驾驶室翻转的上升和下降功能。本发明通过启动电磁换向阀实现手柄快速换向,同时导通控制电路实现电动泵自动泵油,从而实现驾驶室的翻转;驾驶室翻转操作都是通过手持开关完成:旋钮开关实现电磁阀的换向,启动按钮实现电动泵的自动泵油;以上情况表明:本发明用手持开关和电磁换向阀实现了油泵的电动换向;同时保留了手动换向功能,使此结构和操作更加可靠。
