Small concrete mixer manufacturers should not only do their own maintenance and protection in the process of application, but also consider the selection of small concrete pump truck according to the concrete project object, characteristics, the required maximum conveying interval, concrete construction scheme, concrete pump mode and detailed conditions.
建筑的范例和机关混凝土泵车的功效随机型而异，选用机型时除进思虑混凝土浇注量之外，还应思虑建筑的范例和机关、施工手艺要求、现场前提和情况等。凡是选用的混凝土泵车的重要功效参数应与施工要求符合或稍大，若才能过大，则操纵率低，太小，不但对劲不了要求还会加速混凝土泵车的消耗。
The type and structure of construction and the function of concrete pump truck vary randomly. When selecting the model, in addition to considering the amount of concrete pouring, we should also consider the type and structure of construction, construction technical requirements, site conditions and environment, etc. Generally, the primary functional parameters of the selected concrete pump truck shall be consistent with or slightly larger than the construction requirements. If the capacity is too large, the utilization rate is low and too small, which will not only satisfy the requirements, but also accelerate the loss of the concrete pump truck.
每次装料前用水冲洗进料口，使进料口在装料时对峙潮湿；在装料的一路向随车自带的洁净用水水箱中注满水；装料后冲洗进料口，洗净进料口临近残留的混凝土；到工地卸料后，冲洗出料槽，而后向混凝土贮罐内加洁净用水30—40 L；在车辆回程时对峙混凝土贮罐正向慢速转动；下次装料前服膺放掉混凝土贮罐内的污水；每天出工时完整洁净混凝土贮罐及收支料口四周，确保不粘有水泥及混凝土结块。
Wash the inlet with water before loading each time to keep the inlet wet during loading; Fill the cleaning water tank with water during loading; Wash the inlet after loading and clean the residual concrete near the inlet; After unloading at the construction site, flush the discharge chute, and then add 30-40 l of clean water to the concrete storage tank; Keep the concrete storage tank rolling forward and slowly when the vehicle returns; Remember to discharge the sewage in the concrete storage tank before the next loading; At the end of each day, completely clean the concrete storage tank and around the inlet and outlet to ensure that there is no cement and concrete caking.
将一张#600的砂纸置于ATF油中，浸泡约30分钟。把稳肠敲击阀体，使卡滞的阀杆从阀腔孔中落下。能够有须要应用一把小螺丝刀，将其撬出。应用螺丝刀时，把稳不要划伤阀孔。单向阀杆是不是有抵触陈迹。应用ATF油浸泡过的#600砂纸，打磨阀杆上的毛刺，而后在溶剂中洁净阀杆并用紧缩氛围吹干。
Soak a piece #600 of sandpaper in ATF oil for about 30 minutes. Be careful to knock the valve body to make the stuck valve stem fall from the valve cavity hole. It may be necessary to lever it out with a small screwdriver. When using a screwdriver, be careful not to scratch the valve hole. Check the one-way valve stem for signs of conflict. Use the #600 sandpaper soaked in ATF oil to polish the burrs on the valve stem, then clean the valve stem in solvent and blow dry with compressed air.
卷起半张ATF油浸泡过的#600砂纸，将其刺进卡滞阀杆的阀孔中。暗暗扭动砂纸，使砂纸松卷，周密贴合在阀孔表面，而后边推拉，边扭卷砂纸，打磨阀孔。抽出#600砂纸。在溶剂中完整洁净全数阀体，而后用紧缩氛围吹干。在阀杆表面涂ATF油，而后将其落入阀孔中。阀杆应能靠自重落入阀孔底部。不然，反复进程4，重新考试。假设阀杆仍然卡滞，则替代阀体。
Roll up half a piece of #600 sandpaper soaked in ATF oil and stab it into the valve hole of the stuck valve stem. Twist the sandpaper quietly to make it loose and tightly fit on the surface of the valve hole, and then twist the sandpaper while pushing and pulling to polish the valve hole. Draw out #600 sandpaper. Completely clean all valve bodies in solvent and blow dry with compressed air. Coat the surface of the valve stem with ATF oil and drop it into the valve bore. The valve stem shall fall into the bottom of the valve hole by its own weight. Otherwise, repeat process 4 and test from scratch. If the valve stem is still stuck, replace the valve body.
主动化、智能化是一切装备追求的方针，对于情况卑劣、休息强度大的混凝土泵送装备出格重要。此刻小型混凝土泵车主动化手艺已获得了肯定功效。
Automation and intelligence are the goals of all equipment, especially the concrete pumping equipment with bad environment and high labor intensity. At present, the automatic technology of small concrete pump truck has achieved certain results.
对于泵车的堵管，本身堵管是混凝土泵送经常碰到的事，堵管若能早发明并采取精确的方法，凡是都能解除，但发明太晚或不采取精确的方法，管道就能够堵死，致使持久的施工中断，甚至影响建筑品质。防堵管操控选用压力传感器不断监测管道，当梗阻爆发时，管道内压力会爆发变态，压力传感器会将这一旌旗灯号传到PLC，PLC将当即颁布发表警示，一路主动采取疏浚方法。
As for the pipe blockage of pump truck, self pipe blockage is often encountered in concrete pumping. If the pipe blockage can be found early and accurate methods can be adopted, it can usually be eliminated. However, if it is found too late or accurate methods are not adopted, the pipeline may be blocked, resulting in long-term suspension of construction and even affecting the construction quality. The anti blocking pipe control selects the pressure sensor to monitor the pipeline from time to time. When the blockage occurs, the pressure in the pipeline will be abnormal. The pressure sensor will transmit this signal to the PLC, and the PLC will immediately announce the warning and take the initiative to adopt the dredging method together.
智能臂架方面，此刻泵车臂架只能由操纵者间接操控每节臂架的举措，使臂架活动到志向的方位，而智能臂架的每节臂都装有方位传感器，颠末计较机可实现闭环操控和活动协调操控。
In terms of intelligent boom, at present, the operator can only directly control the action of each boom to make the boom move to the desired orientation. Each arm of the intelligent boom is equipped with an orientation sensor, which can complete closed-loop control and motion harmony control through the computer.
由于注册送200可提现的打鱼 会在短时候内凝结成硬块，且对钢材和油漆有肯定的侵蚀性，以是每次应用混凝土贮罐后，洗净粘附在混凝土贮罐及收支料口上的混凝土是逐日掩护必须细心停止的任务。施工顺应性不足，小型混凝土泵车具备矫捷性，并且臂架高度越高，浇注高度和布料半径就越大，施工顺应性也越强，放在施工中应尽量选用高臂架混凝土泵车。
Because the small concrete mixer will solidify into hard blocks in a short time and have certain corrosivity to steel and paint, cleaning the concrete adhered to the concrete storage tank and the inlet and outlet after each use of the concrete storage tank is a daily protection work that must be carried out carefully. The small concrete pump truck is flexible, and the higher the boom height, the greater the pouring height and distribution radius, and the stronger the construction adaptability. The high boom concrete pump truck should be selected as far as possible in the construction.
