电动叉车调速方式你了解吗?

来源:/ 日期:2020-11-16 发布人:hangong

在搬运货物的过程中,我们需要进行变频变速过程,调速过程可分为:节流变速、容积变速,节流变速将控制回路中的流量控制元件截面大小进行改变,可对实行元器件流量进行有效控制,进而可更有效地对电动叉车的运行速度进行调整。因为调整运动速度主要以流通截面转变完成,就会在一定程度上让能耗出现损毁。

In the process of handling goods, we need to carry out frequency conversion and speed change process. The speed control process can be divided into throttle speed change and volume speed change. Throttling speed change will change the cross-section size of flow control elements in the control circuit, which can effectively control the flow of components, and then more effectively adjust the running speed of electric forklift. Because the adjustment of movement speed is mainly completed by the transition of flow section, the energy consumption will be damaged to a certain extent.
而电动叉车的容积变速将控制回路中的变量柱塞泵排量进行改变,这样可对实行元器件进行调整过程。泵控容积变速一方面将电动叉车电机转速比进行变化,也可更进一步对液压泵輸出流量进行改变。此外还可利用变量组织对液压泵排量进行转变,这样便可对液压泵的輸出流量进行改变。
The volume change of electric forklift will change the displacement of variable piston pump in the control circuit, so that the components can be adjusted. On the one hand, the speed ratio of electric forklift motor is changed, and the output flow of hydraulic pump can be further changed. In addition, variable organization can be used to change the displacement of the hydraulic pump, so that the output flow of the hydraulic pump can be changed.

电动叉车的泵源是利用压力反馈式变量柱塞泵完成。在对电机转速进行控制时,通过变频完成,可更进一步完成容积变速。随着持续变动的负荷运行,会逐渐转变为电动叉车的工作压力,进而将工作效率得到进一步提升。根据相关研究数据表示,电动叉车的工作压力通常与反馈压力维持在平衡位置状态中。
The pump source of electric forklift is completed by pressure feedback variable displacement piston pump. When the motor speed is controlled, the volume speed change can be further completed by frequency conversion. With the continuous change of load operation, it will gradually change into the working pressure of electric forklift, and further improve the work efficiency. According to the relevant research data, the working pressure and feedback pressure of electric forklift are usually maintained in a balanced position.
随着电动叉车交流电动机当代控制理论的不断发展,交流变频变速技术也在整个电动叉车行业中得到了更为普遍的使用。
With the continuous development of electric forklift AC motor control theory, AC variable frequency variable speed technology has been widely used in the whole electric forklift industry.
