混凝土搅拌机电气系统如何维护,混凝土搅拌机大家应该都不陌生,混凝土作为一种主要建材其市场需求量非常大。很多建筑工程都会使用混凝土搅拌机进行混凝土生产。今天我就来和大家聊聊混凝土搅拌机的相关话题。
How to maintain the electrical system of concrete mixer, concrete mixer everyone should be familiar with, concrete as a major building material, its market demand is very large. Many construction projects will use concrete mixer for concrete production. Today I'm going to talk about the concrete mixer.
混凝土搅拌机的电气控制系统需是控制混凝土搅拌机的主传动电机,供水系统电机,上料,下料等的电机。所有电器控制元件都设在配电箱中。电器元件控制满足的使用要求:主电机可以点动以满足安装修理过程的要求。
The electrical control system of concrete mixer should be the main drive motor of concrete mixer, the motor of water supply system, the motor of loading and unloading, etc. All electrical control elements are set in the distribution box. Electrical component control to meet the use requirements: the main motor can be inched to meet the requirements of the installation and repair process.
电气控制线路设有空气开关,熔断器,热继电器具有短路保护,过载保护,断相保护的功能,所有控制按钮及空气开关手柄和指示灯均布置在配电箱门上,并设有门锁。配电箱内的电器元件安装在一块铁板上,安全可靠,操作维修方便。
The electric control circuit is equipped with air switch, fuse and thermal relay, which have the functions of short-circuit protection, overload protection and open phase protection. All control buttons, air switch handles and indicator lights are arranged on the door of the distribution box, and the door lock is set. The electrical components in the distribution box are installed on an iron plate, which is safe, reliable and convenient for operation and maintenance.
混凝土搅拌机供水系统是电动机、水泵、节流阀及管路等组成,启动水泵,即可将注入搅拌筒,水的流量通过闸阀调节,供水总量由时间继电器控制。当按钮转到“时控”位置时,水泵会按设定的时间运转和自动停止,当按钮转到“手动”位置时,可连续供水。
The water supply system of concrete mixer is composed of motor, water pump, throttle valve and pipeline. When the water pump is started, it can be injected into the mixing drum. The water flow is regulated by gate valve, and the total amount of water supply is controlled by time relay. When the button is turned to the "time control" position, the water pump will run and stop automatically according to the set time. When the button is turned to the "manual" position, the water supply can be continuous.
在混凝土搅拌机生产混凝土时,对混凝土质量影响较大的除了搅拌机自身的工作性能以外,就是供水精度。由于供水精度要求控制在2%的范围内,故如何更好的满足精度问题是供水方式的选择,应加以认真考虑。
When the concrete mixer is used to produce concrete, besides the working performance of the mixer itself, the accuracy of water supply has a great impact on the quality of concrete. As the accuracy of water supply is required to be controlled within 2%, how to better meet the accuracy is the choice of water supply mode, which should be seriously considered.
目前,国内运用的主要是时间继电器或虹吸式水箱控制供水精度。但由于虹吸式水箱在不配备站的情况下有诸多不便,故而选用混凝土搅拌机专用水泵配以时间继电器控制,在误差允许范围内让供水时间略大一些,如果砂石过湿则供水时间相对短一些。
At present, time relay or siphon water tank are mainly used to control water supply precision in China. But the siphon type water tank has many inconveniences when it is not equipped with a station, so the special water pump for concrete mixer with time relay control is selected to make the water supply time slightly larger within the allowable error range. If the sand is too wet, the water supply time is relatively shorter.
