电动剪叉式升降机工作原理？

The hydraulic oil is formed by the vane pump to a certain pressure. The oil filter, the explosion-proof electromagnetic reversing valve,

the throttle valve, the hydraulic control check valve and the balance valve enter the lower end of the liquid cylinder, so that the piston of the liquid cylinder moves upward,

lifting the weight. The oil returning from the upper end of the liquid cylinder is returned to the fuel tank through the explosion-proof electromagnetic reversing valve,

and the rated pressure is adjusted through the overflow valve, and the pressure gauge reading value is observed through the pressure gauge.

液压油由叶片泵在一定压力下形成。机油滤清器、防爆电磁换向阀、节流阀、液控止回阀和平衡阀进入液缸下端，使液缸活塞向上移动，提升重量。

从液缸上端回流的油通过防爆电磁换向阀返回油箱，通过溢流阀调节额定压力，通过压力表观察压力表读数值。

The piston of the cylinder moves downwards (both heavy objects drop). The hydraulic oil enters the upper end of the liquid cylinder through the explosion-proof electromagnetic reversing valve,.

and the oil returning to the fuel tank is returned to the fuel tank through the balance valve, the hydraulic control check valve, the throttle valve and the explosion-proof electromagnetic reversing valve.

In order to make the weight drop smoothly, the brake is safe and reliable, and a balance valve is arranged on the oil return road to balance the circuit and maintain

the pressure so that the descending speed is not changed by the heavy object, and the flow rate is adjusted by the throttle valve to control the lifting speed.

气缸的活塞向下移动（两个重物都掉落）。液压油通过防爆电磁换向阀进入液缸上端，返回油箱的油通过平衡阀、液控止回阀、节流阀和防爆电磁换向阀返回油箱。

为使重量平稳下降，制动器安全可靠，在回油道上设置平衡回路平衡，保持压力，使下降速度不因重物而改变，由节流阀调节流量，控制提升速度。

In order to make the brake safe and reliable, prevent accidents, increase the hydraulic control check valve, that is, the hydraulic lock, to ensure safe self-locking

when the hydraulic line accidentally bursts. An overloaded voice alarm is installed to distinguish between overload or equipment failure. The electronic control system can control

the rotation of the motor through the explosion-proof button, make the explosion-proof electromagnetic reversing valve reverse direction, to keep the load up or down,

and adjust the time delay amount through the “LOGO” program to avoid the frequent start of the motor. The lifting is not flexible, the card machine phenomenon, and prolonging the service life.

为了使制动器安全可靠，防止事故发生，增加液压控制止回阀，即液压锁，

确保液压管路意外爆裂时安全自锁。安装过载语音报警器，用于区分过载或设备故障。

电控系统可以通过防爆按钮控制电机的旋转，使防爆电磁换向阀反转方向，保持负载上升或下降，

并通过“LOGO”程序调整延时量，避免电机频繁启动。升降不灵活，出现梳卡机现象，并延长了使用寿命。
