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.
修建的類(lèi)型和構造混凝土泵車(chē)的功能隨機型而異，選用機型時(shí)除進(jìn)思考混凝土澆注量以外，還應思考修建的類(lèi)型和構造、施工技術(shù)請求、現場(chǎng)條件和環(huán)境等。通常選用的混凝土泵車(chē)的首要功能參數應與施工請求相符或稍大，若能力過(guò)大，則利用率低，過(guò)小，不只滿(mǎn)意不了請求還會(huì )加快混凝土泵車(chē)的損耗。
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.
每次裝料前用水沖刷進(jìn)料口，使進(jìn)料口在裝料時(shí)堅持濕潤；在裝料的一起向隨車(chē)自帶的清潔用水水箱中注滿(mǎn)水；裝料后沖刷進(jìn)料口，洗凈進(jìn)料口鄰近殘留的混凝土；到工地卸料后，沖刷出料槽，然后向混凝土貯罐內加清潔用水30—40 L；在車(chē)輛回程時(shí)堅持混凝土貯罐正向慢速滾動(dòng)；下次裝料前牢記放掉混凝土貯罐內的污水；天天收工時(shí)完全清潔混凝土貯罐及進(jìn)出料口周?chē)?，確保不粘有水泥及混凝土結塊。
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.
將一張#600的砂紙置于A(yíng)TF油中，浸泡約30分鐘。當心腸敲擊閥體，使卡滯的閥桿從閥腔孔中落下?？赡苡斜匾\用一把小螺絲刀，將其撬出。運用螺絲刀時(shí)，當心不要劃傷閥孔。單向閥桿是否有沖突痕跡。運用ATF油浸泡過(guò)的#600砂紙，打磨閥桿上的毛刺，然后在溶劑中清潔閥桿并用壓縮空氣吹干。
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.
卷起半張ATF油浸泡過(guò)的#600砂紙，將其刺進(jìn)卡滯閥桿的閥孔中。悄悄扭動(dòng)砂紙，使砂紙松卷，嚴密貼合在閥孔外表，然后邊推拉，邊扭卷砂紙，打磨閥孔。抽出#600砂紙。在溶劑中完全清潔全部閥體，然后用壓縮空氣吹干。在閥桿外表涂ATF油，然后將其落入閥孔中。閥桿應能靠自重落入閥孔底部。不然，重復過(guò)程4，從頭測驗。假如閥桿依然卡滯，則替換閥體。
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.
主動(dòng)化、智能化是一切設備尋求的目標，關(guān)于環(huán)境惡劣、勞動(dòng)強度大的混凝土泵送設備特別主要?，F在小型混凝土泵車(chē)主動(dòng)化技術(shù)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.
關(guān)于泵車(chē)的堵管，自身堵管是混凝土泵送常常遇到的事，堵管若能早發(fā)現并采納準確的辦法，通常都能排除，但發(fā)現太晚或沒(méi)有采納準確的辦法，管道就可能堵死，導致長(cháng)期的施工中止，乃影響修建質(zhì)量。防堵管操控選用壓力傳感器不時(shí)監測管道，當阻塞發(fā)作時(shí)，管道內壓力會(huì )發(fā)作反常，壓力傳感器會(huì )將這一信號傳到PLC，PLC將當即宣布警示，一起主動(dòng)采納疏通辦法。
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，現在泵車(chē)臂架只能由操作者直接操控每一節臂架的動(dòng)作，使臂架運動(dòng)到抱負的方位，而智能臂架的每一節臂都裝有方位傳感器，經(jīng)過(guò)計算機可完成閉環(huán)操控和運動(dòng)和諧操控。
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.
因為小型混凝土攪拌車(chē)會(huì )在短時(shí)間內凝固成硬塊，且對鋼材和油漆有必定的腐蝕性，所以每次運用混凝土貯罐后，洗凈粘附在混凝土貯罐及進(jìn)出料口上的混凝土是每日保護必須仔細進(jìn)行的工作。施工適應性有余，小型混凝土泵車(chē)具有靈活性，并且臂架高度越高，澆注高度和布料半徑就越大，施工適應性也越強，放在施工中應盡量選用高臂架混凝土泵車(chē)。
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.
