一、前言近来,从节能方面来看,水泵调速运转方式应用面较广。特别是由于半导体技术的发展,这种调速方式价格下降,能够简便地广泛使用交流感应电动机,因此,频率变换器受到人们注意。采用频率变换器进行水泵调速控制,是应用出水压力恒定控制方式的自动给水装置,该装置已商品化。其内容介绍如下。二、装置概要 1.外形给水泵采用JIS B8313小型离心泵,由标准的2极电动机直接驱动。把其它给水所需的机械设备等组装在设备底座上,并使其集
First, the foreword Recently, from the energy-saving point of view, the pump speed control mode of operation is broader. Especially due to the development of semiconductor technology, the price of this speed regulation method is reduced, and the AC induction motor can be widely used conveniently. Therefore, the frequency converter is attracting attention. The use of frequency converter pump speed control, is the application of constant pressure water outlet automatic control device, the device has been commercialized. The content is as follows. Second, the device outline 1. Appearance Water pump using JIS B8313 small centrifugal pump, driven by the standard 2-pole motor directly. The other necessary water supply machinery and equipment assembled on the base of the equipment, and make it
