Ladder motor pump system
A ladder motor pump system (300) includes: a hydraulic fluid tank (206) holding hydraulic fluid; a hydraulic pump (304) that draws hydraulic fluid from the hydraulic fluid tank (206) and pressurizes the hydraulic fluid; a one-way electric motor (302) that drives the hydraulic pump (304); a hydraulic ladder actuator (228) that actuates the ladder (102) in a first mode (128, 132, 130) and a second mode (130, 250, 128); a hydraulic fluid circuit (316) that directs hydraulic fluid from the hydraulic ladder actuator (228) to the hydraulic fluid tank; and a regulator (222) that directs the pressurized hydraulic fluid from the outlet (312) of the hydraulic pump (304) to the hydraulic fluid tank (206), mixes the pressurized hydraulic fluid with unpressurized hydraulic fluid in the hydraulic fluid tank (206), and reduces the temperature of the pressurized hydraulic fluid when the pressure of the pressurized hydraulic fluid exceeds a preselected threshold pressure. The electric motor (302) and pump (304) include bosses that provide an increased ground connection to the electrical ground (306), thereby reducing electrical resistance and heat generated.
一种梯子马达泵系统(300)包括：保持液压流体的液压流体箱(206)；液压泵(304)，所述液压泵从液压流体箱(206)抽吸液压流体并且对液压流体加压；单向电动马达(302)，所述单向电动马达驱动液压泵(304)；液压梯子致动器(228)，所述液压梯子致动器以第一模式(128、132、130)和第二模式(130、250、128)致动梯子(102)；液压流体回路(316)，所述液压流体回路将液压流体从液压梯子致动器(228)引导到液压流体箱；以及调节器(222)，当加压液压流体的压力超过预选阈值压力时，所述调节器将加压液压流体从液压泵(304)的出口(312)引导到液压流体箱(206)，将加压液压流体与液压流体箱(206)中的未加压液压流体混合并且降低加压液压流体的温度。电动马达(302)和泵(304)包括凸台，所述凸台提供到电接地(306)的增加的接地连接，从而减少电阻和产生的热。
