1、 Proper operation of self mixing concrete mixer and ready mixed concrete

a、 先注入总水量2/3的水。

a. First, inject 2 / 3 of the total amount of water.

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 coarse aggregate, 1 / 2 of sand and all cement are successively sent to the mixing drum, and then the remaining 1 / 2 of coarse aggregate and water are sent to 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. The speed of the mixing drum and the mixing time "the speed of the mixing drum when feeding: 6-10 rpm; The rotation speed of the mixing cylinder during mixing is 6-10 rpm; Mixing time: 10-16 minutes.

d、自拌混凝土搅拌车，搅拌完毕后的搅动及出料方法与前述相同。

d. The mixing and discharging methods of self mixing concrete mixer truck after mixing are the same as above.

二、 自拌混凝土搅拌车，供水系统正常操作：

2、 Self mixing concrete mixer, normal operation of water supply system:

1、采用水泵供水：

1. Water supply by water pump:

a、 先打开驾驶室里的水泵翘板开关，再打开蜂鸣开关，水泵即可工作，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, the water pump can work, at the same time, the buzzer sends out a "beep beep beep".

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 valve.

d、 冲洗车身时，先开启水枪阀门，而后可直接使用车尾水枪。

d. When washing the car body, open the water gun valve first, and then use the tail water gun directly.

2、采用气压供水：

2. Air pressure water supply:

① 先打开驾驶室供气开关，当主车压力表达到8kg/cm2压力再打开供水系统手动气开关，当压力表达到2 kg/cm2压力时即可工作。

① Turn on the air supply switch of the cab first, and then turn on the manual air switch of the water supply system when the pressure of the main vehicle reaches 8kg / cm2. 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 car body, first open the valve at the bottom of the water tank, and then directly use the rear washing device.
