An electric hydraulic device of a jack belongs to the technical field of hoisting facilities. Which comprises a motor, an oil pump, a valve body and an oil cylinder, and is characterized in that the motor is in transmission connection with the oil pump, the motor and the oil pump are horizontally arranged on the left side of the valve body, the oil cylinder is horizontally arranged on the right side of the valve body, and the oil pump is a gear pump and is communicated with the oil cylinder through an oil channel formed in the valve body. The advantages are that the structure is simplified and the size is reduced; the motor and the oil pump are arranged on the same side of the valve body, and the oil cylinder is arranged on the other side of the valve body, so that space is optimized, components and weight are reasonably distributed relative to the valve body, maintenance is facilitated, flow resistance of hydraulic oil serving as fluid can be reduced, and the service life of the valve body is prolonged. And on the other hand, the installation reliability and the use safety can be guaranteed.
一种千斤顶的电动液压装置,属于起重设施技术领域。包括电机、油泵、阀体和油缸,特点是:所述电机与所述油泵传动连接并且由油泵连同电机以卧置状态同设在所述阀体的左侧,而所述油缸同样以卧置状态设置在阀体的右侧,所述油泵为齿轮泵并且通过开设于阀体内的油道与所述油缸相通。优点:简化了结构并且缩小了体积;由于将电机连同油泵设置在了阀体的同一侧,而将油缸设置在了阀体的另一侧,因而得以优化空间,使部件及重量相对于阀体分布合理,一方面有利于维护,另一方面能减少作为流体的液压油的流动阻力,再一方面可保障安装的可靠性以及使用的安全性。
