调速控制器

我们的生活离不开电。电在我们的生活中无处不在，但电是zui消耗能源的产品之一，而高效节能的电设备则是降低能源消耗所必不可少，下面我们就来了解一下如何实现高效节能？从技术上讲主要是从电机到电控，从控制到自动控制这三个方面来实现高效节能。以电机为例，我们通常所说的“变频”就是通过改变电机运行速度来实现节能效果。如果说电机是一个高速旋转而不改变电机转速以达到节能目的的话，那么调速控制器则是一种提高设备转矩达到节能目的，让电机平稳运转才是我们zui希望看到的结果。高效节能是现代企业经营过程中非常重要的问题，但是我们会发现很多设备都存在着明显的浪费现象，很多企业都没有意识到这一点，而要改善这种现象，zui有效、zui快捷又节能的方式就是采用高效节能产品来实现我们节能计划目标，下面就来了解一下高效节能产品吧！

一、节能与变速
节能是指将动力转变为经济效率，变速便是将动力转换成可调整的速度，而不是传统的定速或低速行驶（例如发动机怠速运行）。通常，变速技术主要有两种形式：转矩不变技术和转矩恒速技术。其主要特点是通过改变转矩来控制运行速度和运行方式。这种方法的优点是能够很好的控制电机，还能够使转速和电机的转矩保持一致，而缺点则是效率较低。因此，变速的应用越来越广泛。

二、变频调速控制器
目前市面上使用的变频器分为直流、交流和谐波三种，其中直流变频变频器又可分为变频器直联变频器交流电直联变频器以及全直流变频变频器等。交流型变频调速控制器是根据电动机运行时的变化，在电机正常工作时，对电动机电流、电压变化进行微处理器处理，使之能适应电动机运行的需要；在某些特殊情况下，可将电动机的功率因数调至恒定值以提高电机电流稳定性，从而提高电机寿命。调速控制器在工业控制中，一般是采用一种电动机启动、运行的控制方式，这种控制方式有三种情况：电机在运行过程中突然停机，使电机不能正常工作或持续工作两天以上；当控制系统发生故障时，又不得不重新启动或连续运行一段时间；由于突然停机而导致设备损坏使用户无法正常生产或不能及时得到维修后设备仍无法继续使用。以上就是基于不同电机类型对其能耗控制技术带来的区别；根据调速情况需要对不同类型电动机进行综合控制还是简单地将电动机分为普通电动机和异步电动机两种方式进行控制主要区别在于：普通电机控制可以分为单相或三相电动机控制。

Woodward speed control controller Woodward8444-1067, generally, there are two main forms of speed change technology: torque constant technology and torque constant speed technology. Its main feature is to control the running speed and running mode by changing the torque. C+1 53-962376-07 The advantage of this method is that it can control the motor well, and it can also keep the speed and the torque of the motor consistent, and the disadvantage is that the efficiency is low. Therefore, the application of variable speed is more and more extensive.

Speed regulating controller

We can't live without electricity. Electricity is everywhere in our lives, but electricity is one of the most energy-consuming products, and energy-efficient electrical equipment is essential to reduce energy consumption, here we come to understand how to achieve efficient energy saving? Technically speaking, it is mainly from the motor to the electric control, from the control to the automatic control of these three aspects to achieve high efficiency and energy saving. Taking the motor as an example, what we usually call "frequency conversion" is to achieve energy-saving effects by changing the running speed of the motor. If the motor is a high-speed rotation without changing the motor speed to achieve the purpose of energy saving, then the speed controller is a way to improve the torque of the equipment to achieve the purpose of energy saving, so that the smooth operation of the motor is the result we most want to see. High efficiency and energy saving is a very important problem in the modern business process, but we will find that a lot of equipment there is an obvious waste phenomenon, many companies are not aware of this, and to improve this phenomenon, the most effective, the most efficient and energy-saving way is to use energy-saving products to achieve our energy-saving plan goals, let's learn about energy-saving products!

First, energy saving and speed change
Energy saving refers to the transformation of power into economic efficiency, and variable speed is the conversion of power into an adjustable speed, rather than the traditional constant speed or low speed driving (such as engine idling). Generally, there are two main forms of variable speed technology: torque constant technology and torque constant speed technology. Its main feature is to control the running speed and running mode by changing the torque. The advantage of this method is that it can control the motor well, and it can also keep the speed and the torque of the motor consistent, and the disadvantage is that the efficiency is low. Therefore, the application of variable speed is more and more extensive.

Second, frequency conversion speed control
At present, the frequency converter used on the market is divided into DC, AC and harmonic three kinds, of which DC frequency converter can be divided into frequency converter direct-connected frequency converter AC direct-connected frequency converter and full DC frequency converter. Ac type variable frequency speed control controller is based on the changes of the motor running, when the motor is working normally, the motor current and voltage changes are processed by microprocessor, so that it can meet the needs of the motor running; In some special cases, the power factor of the motor can be adjusted to a constant value to improve the current stability of the motor, thereby improving the life of the motor. In industrial control, a motor is generally used to start and run the control mode, this control mode has three situations: the motor suddenly stops during operation, so that the motor can not work normally or continue to work for more than two days; When the control system fails, it has to be restarted or run continuously for a period of time; Due to the sudden shutdown caused by equipment damage users can not normal production or can not be repaired in time after the equipment can not continue to use. These are the differences in energy consumption control technology based on different motor types; According to the speed regulation situation, it is necessary to carry out comprehensive control of different types of motors or simply divide the motor into ordinary motors and asynchronous motors in two ways to control the main difference is that ordinary motor control can be divided into single-phase or three-phase motor control.
