混凝土搅拌车的上装电气系统由三部分组成：供水系统电控装置（电动水泵控制部分、气压式供水系统电控报警装置）、冷却风扇控制部分和后示廓灯、侧标志灯、工作灯部分。下面小编为您讲解。
The upper electrical system of the concrete mixer consists of three parts: the electric control device of the water supply system (the electric water pump control part, the electric control alarm device of the pneumatic water supply system), the cooling fan control part, and the rear clearance lamp, side marker lamp, and work lamp part. The following section explains it for you.
1）供水系统电控装置
1) Electric control device of water supply system
①电动水泵控制部分：电动水泵操作开关位于车后部右侧开关盒上，在电动水泵工作前应先确保发动机运转、水箱有水、水管阀门打开。水箱水用完时应关停水泵，严禁无水空转电动水泵，以免损坏电动水泵。电动水泵工作时开关盒内蜂鸣器鸣叫，起警示作业。
① Electric water pump control part: the electric water pump operating switch is located on the right switch box at the rear of the vehicle. Before the electric water pump works, ensure that the engine is running, there is water in the water tank, and the water pipe valve is open. When the water in the water tank is used up, the water pump shall be shut down. It is strictly prohibited to idle the electric water pump without water to avoid damage to the electric water pump. When the electric water pump is working, the buzzer in the switch box sounds to warn.
②气压式供水系统电控报警装置：打开驾驶室内原水泵开关，气压式供水系统蜂鸣控制器继电器得电，蜂鸣器鸣叫，同时电磁气阀接通，气源从储气筒经电磁阀进入喷水压力水罐，打开喷水阀进行喷水洗车作业，喷水洗车完毕后蜂鸣器仍在鸣叫，提醒操作者关闭水泵开关。
② Electric control alarm device of pneumatic water supply system: turn on the raw water pump switch in the cab, the buzzer controller relay of the pneumatic water supply system is powered on, the buzzer buzzes, and the solenoid valve is connected at the same time. The air source enters the water spray pressure tank from the air reservoir through the solenoid valve. Turn on the water spray valve for water spray washing. After the water spray washing, the buzzer still buzzes, reminding the operator to turn off the water pump switch.
2）冷却风扇控制部分
2) Cooling fan control part
冷却风扇的启停由温控开关自动控制，温度高于65℃时风扇启动，低于60℃时风扇停止。温控开关位于冷却器上，继电器与保险片在驾驶室内配电盒内。
The start and stop of the cooling fan is automatically controlled by the temperature control switch. The fan starts when the temperature is higher than 65 ℃ and stops when the temperature is lower than 60 ℃. The temperature control switch is located on the cooler, and the relay and fuse are located in the central power distribution box in the cab.
3）混凝土搅拌车的后示廓灯、侧标志灯、工作灯部分后示廓灯、侧标志灯用于夜间表示车后部轮廓大小、侧面轮廓，与后牌照灯同时点亮、熄灭。工作灯用于夜间进料与卸料照明，开关在驾驶室内。
3) The rear clearance lamp, side marker lamp, work lamp and some rear clearance lamps and side marker lamps of the concrete mixer are used to indicate the size and side contour of the rear of the vehicle at night, and are turned on and off at the same time as the rear license plate lamp. The working light is used for the lighting of feeding and discharging at night, and the switch is in the cab.
