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.
修建的类型和构造混凝土泵车的功能随机型而异，选用机型时除进思考混凝土浇注量以外，还应思考修建的类型和构造、施工技术请求、现场条件和环境等。通常选用的混凝土泵车的首要功能参数应与施工请求相符或稍大，若能力过大，则利用率低，过小，不只满意不了请求还会加快混凝土泵车的损耗。
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.
每次装料前用水冲刷进料口，使进料口在装料时坚持湿润；在装料的一起向随车自带的清洁用水水箱中注满水；装料后冲刷进料口，洗净进料口邻近残留的混凝土；到工地卸料后，冲刷出料槽，然后向混凝土贮罐内加清洁用水30—40 L；在车辆回程时坚持混凝土贮罐正向慢速滚动；下次装料前牢记放掉混凝土贮罐内的污水；天天收工时完全清洁混凝土贮罐及进出料口周围，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。当心肠敲击阀体，使卡滞的阀杆从阀腔孔中落下。可能有必要运用一把小螺丝刀，将其撬出。运用螺丝刀时，当心不要划伤阀孔。单向阀杆是否有冲突痕迹。运用ATF油浸泡过的#600砂纸，打磨阀杆上的毛刺，然后在溶剂中清洁阀杆并用压缩空气吹干。
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。悄悄扭动砂纸，使砂纸松卷，严密贴合在阀孔外表，然后边推拉，边扭卷砂纸，打磨阀孔。抽出#600砂纸。在溶剂中完全清洁全部阀体，然后用压缩空气吹干。在阀杆外表涂ATF油，然后将其落入阀孔中。阀杆应能靠自重落入阀孔底部。不然，重复过程4，从头测验。假如阀杆依然卡滞，则替换阀体。
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、智能化是一切设备寻求的目标，关于环境恶劣、劳动强度大的混凝土泵送设备特别主要。现在小型混凝土泵车主动化技术已取得了必定成果。
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.
关于泵车的堵管，自身堵管是混凝土泵送常常遇到的事，堵管若能早发现并采纳准确的办法，通常都能排除，但发现太晚或没有采纳准确的办法，管道就可能堵死，导致长期的施工中止，乃影响修建质量。防堵管操控选用压力传感器不时监测管道，当阻塞发作时，管道内压力会发作反常，压力传感器会将这一信号传到PLC，PLC将当即宣布警示，一起主动采纳疏通办法。
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，现在泵车臂架只能由操作者直接操控每一节臂架的动作，使臂架运动到抱负的方位，而智能臂架的每一节臂都装有方位传感器，经过计算机可完成闭环操控和运动和谐操控。
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.
因为小型混凝土搅拌车会在短时间内凝固成硬块，且对钢材和油漆有必定的腐蚀性，所以每次运用混凝土贮罐后，洗净粘附在混凝土贮罐及进出料口上的混凝土是每日保护必须仔细进行的工作。施工适应性有余，小型混凝土泵车具有灵活性，并且臂架高度越高，浇注高度和布料半径就越大，施工适应性也越强，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.
