在日常使用混凝土搅拌车的时候，车主朋友们是否有留意预拌混凝土操作及供水操作？下面小编就带各人来了解一番。
When using the concrete mixer daily, do the car owners pay attention to the operation of ready mixed concrete and water supply? Now I'll take you to know something.
一、预拌混凝土正确操作：
1、 Correct operation of ready mixed concrete:
a、先注入总水量2/3的水。
a. First, inject 2/3 of the total water volume.
b、将1/2的粗骨料，1/2的砂，全部的水泥顺次送入搅拌筒，随后再将余下的1/2粗骨料和水送入。
b. 1/2 of the coarse aggregate, 1/2 of the sand and all the cement are sent into the mixing drum in sequence, and then the remaining 1/2 of the coarse aggregate and water are sent into the mixing drum.
c、搅拌筒转速及搅拌时间“进料时搅拌筒的转速：6—10转/分；搅拌时搅拌筒的转速：6—10转/分；搅拌时间：10—16分钟。
c. Rotating speed and mixing time of mixing drum: rotating speed of mixing drum during feeding: 6-10 r/min; rotating speed of mixing drum during mixing: 6-10 r/min; mixing time: 10-16 min.
d、搅拌完毕后的搅动及出料要领与前述相同。
d. The stirring and discharging methods after mixing are the same as those mentioned above.
二、供水系统正常操作：
2、 Normal operation of water supply system:
1、接纳水泵供水：
1. Water is supplied by water pump:
a、先翻开驾驶室里的水泵翘板开关，再翻开蜂鸣开关，水泵即可事情，同时，蜂鸣器发出“嘟嘟嘟”的叫声。
a. First turn on the rocker switch of the water pump in the cab, then turn on the buzzer switch, and the water pump can work. At the same time, the buzzer gives out a "beep beep" sound.
b、向搅拌筒内加水或冲洗料斗槽时，开启“料斗”阀门。
b. When adding water to the mixing drum or flushing the hopper tank, open the "hopper" valve.
c、冲洗出料溜槽时，开启溜槽阀们。
c. When flushing the discharge chute, open the chute valves.
d、冲洗车身时，先开启水枪阀门，此后可直接使用车尾水枪。
d. When washing the body, first open the water gun valve, and then directly use the tail water gun.
2、接纳气压供水：
2. Pneumatic water supply:
①先翻开驾驶室供气开关，当主车压力表抵达8kg/cm2压力再翻开供水系统手动气开关，当压力表抵达2kg/cm2压力时即可事情。
① First turn on the air supply switch in the cab. When the main vehicle pressure reaches 8kg/cm2, turn on the manual air switch of the water supply system. When the pressure reaches 2kg/cm2, it can work.
②向搅拌筒内加水，冲洗料斗槽、卸料槽时，先开启水箱底部阀门，再开启“料斗”阀门。
② When adding water to the mixing drum and flushing the hopper tank and discharge tank, first open the valve at the bottom of the water tank, and then open the "hopper" valve.
③冲洗车身时，先开启水箱底部阀门，后直接使用车尾冲洗装置。
③ When washing the body, first open the valve at the bottom of the water tank, and then directly use the rear washing device.
This is the end of the explanation of the normal operation of the premixed concrete and water supply of the mixer truck. If you have any questions about this, please come to our website Look!
