小型自上料混凝土攪拌罐車的操作人員需經培訓后方可上崗操作。所泵送的混凝土應滿足混凝土泵車的可泵性要求?;炷帘密嚤盟妥鳂I要害可參照混凝土泵的運用。泵送間斷5min以上時,必須將結束軟管內的混凝土排出。否則因為結束軟管內的混凝土脫水,再次泵送作業時混凝土就會激烈的噴出,向四處噴濺,那樣結束軟管很容易受損。為了改動臂架或混凝土泵車的方位而需要折疊、擴展或回收布料桿時,要先反泵1~2次后再動作,這么可放置在動作時輸送管道內的混凝土落下或噴濺。
The operators of small concrete mixing truck can only operate after professional training. The pumped concrete shall meet the pumpability requirements of concrete pump truck. Concrete pump truck pumping operation key can refer to the use of concrete pump. When the pumping is interrupted for more than 5 minutes, the concrete in the end hose must be discharged. Otherwise, due to the end of the concrete dehydration in the hose, the concrete will be sprayed fiercely and splashed around when pumping again, so the end hose is easy to be damaged. In order to change the orientation of the boom or concrete pump truck and need to fold, expand or recycle the distributing boom, first reverse the pump for 1 ~ 2 times and then act, so that the concrete placed in the conveying pipeline can fall or splash.
管道清洗有兩種方法水洗和氣洗。不管是水洗或氣洗,都要將閥箱體和料斗清洗潔凈。水洗時,把用水浸過的扎成圓柱形的水泥袋和清洗球先后裝進已清洗潔凈的錐管中,接上錐管、管道,關閉卸料門,再向料斗注滿水。泵送水,直到清洗球從輸送管的前端冒出中止。氣洗即壓縮空氣吹洗,是把浸透水的清洗球先塞進氣洗接頭,再接與變徑管相接的榜首根直管,并在管道的結束接上安全蓋,安全蓋的孔口要朝下。
There are two methods of pipeline cleaning: water washing and air washing. Whether it is water washing or air washing, the valve box and hopper should be cleaned. When washing with water, put the cylindrical cement bag and cleaning ball soaked with water into the cleaned taper pipe, connect the taper pipe and pipe, close the discharge door, and then fill the hopper with water. Pump water until the cleaning ball comes out from the front of the delivery pipe. Air cleaning, namely compressed air blowing, is to plug the water soaked cleaning ball into the air inlet washing joint first, then connect it to the top straight pipe connected with the reducer, and connect the safety cover at the end of the pipe, with the orifice of the safety cover facing down.

分析泵送電磁閥來電正常,就可以說明行駛、泵送方位查看應當正常,但是從頭查看:I2.5點亮,分動箱方位查看靠近開關點亮,汽車行駛、泵送動作隨駕駛室操作動作正常,說明行駛、泵送控制電路無缺點。發動機升速正常,而系統無壓力,方位查看又無缺點,因此斷定缺點為分動箱內部撥叉出現問題。正、反泵觀察壓力表,壓力為0,系統無壓力。查看DT1電磁閥來電正常,后手動頂其閥芯,缺點照常。
If the power of the pumping solenoid valve is normal, it can show that the driving and pumping direction should be normal, but from the beginning: i2.5 is on, the transfer case direction is on, the proximity switch is on, and the driving and pumping action of the car is normal with the cab operation, which shows that the driving and pumping control circuit has no defects. The engine speed up is normal, the system has no pressure, and the azimuth check has no defects. Therefore, it is concluded that the defect is the internal fork of the transfer case. Observe the pressure gauge of positive and negative pump, the pressure is 0, and there is no pressure in the system. Check dt1 solenoid valve power normal, after the manual top of its spool, shortcomings as usual.
整機水平放置時所容許的傾斜角為3o,更大的水平傾斜角會使布料的轉向齒輪超載,并危及機器的穩定性。假設布料桿在移動時其間的某一個支腿或幾個支腿早年離過地,就必須從頭設定支腿,直至一切的支腿都能一向可靠的支撐在地面上。若終究一節布料桿能處于水平方位,對泵送來說是更理想的。假設這節布料桿的方位呈水平情況,那么混凝土的活動速度就會怠慢,然后可減少輸送管道和結束軟管的磨損,當泵送間斷時,只需結束軟管內的混凝土才會流出來。假設終究一節布料桿呈向下傾斜情況,那么在這有些輸送管道內的混凝土就會在自重作用下加速活動,致使在泵送間斷時輸送管道內的混凝土還會繼續流出。
When the whole machine is placed horizontally, the maximum allowable tilt angle is 3O. A larger horizontal tilt angle will overload the steering gear of the cloth and endanger the stability of the machine. Assuming that one or several legs of the boom leave the ground early when it is moving, it is necessary to set the legs from the beginning until all the legs can be reliably supported on the ground. If a section of distributing rod can be in horizontal position after all, it is the most ideal for pumping. Assuming that the position of the boom is horizontal, the movement speed of concrete will slow down, and then the abrasion of the delivery pipe and the end hose can be reduced. When the pumping is interrupted, only the concrete in the end hose will flow out. Assuming that after all a section of distributor is inclined downward, the concrete in some conveying pipes will accelerate under the action of self weight, so that the concrete in the conveying pipe will continue to flow out when the pumping is interrupted.
