二次构造柱泵 混凝土输送泵 砂浆细石混泥土浇注泵 上料机

搅拌车载泵对混凝土软硬程度的要求是把水泥、砂石骨料和水混兼并拌制成混凝土混合料的机械。主要由拌筒、加料和卸料组织、供水系统、原动机、传动组织、机架和支承设备等组成。

搅拌拖泵，衔接的动力组织及由传动组织带动的滚筒，在滚筒筒体上环绕滚筒筒体设置的齿圈，传动轴上设置与齿圈啮合的齿轮。

English：Second-hand agitator pump is a machine that mixes cement, gravel aggregate and water into a concrete mixture. It is mainly composed of mixing barrel, feeding and unloading organization, water supply system, prime mover, transmission organization, frame and support equipment. Stirred towing pump, connecting power organization and the drum driven by the transmission organization, the gear ring set around the cylinder body on the drum body, and the gear engaged with the gear ring on the transmission shaft.
 
新式结构简略、合理，选用齿轮、齿圈啮合后，可有用战胜雨雾气候时，托轮和搅拌机滚筒之间的打滑现象选用的传动组织又可进一步确保消除托轮和搅拌机滚筒之间的混凝土软硬打滑现象。
 
English：The new type of structure is simple and reasonable. After using gears and gear rings to mesh, it can be used to overcome the rain and fog climate. The transmission structure selected between the wheel and the blender roller can further ensure the elimination of the wheel and the blender roller. Concrete soft and hard skid phenomenon between the drum.
 
所以搅拌车载泵对混凝土软硬程度的要求对混凝土的要求我们应该做到以下几点：
　　
**点、车载搅拌泵对混凝土软硬程度的要求混凝土试配时应选用工程实际使用的原资料，二手搅拌拖泵每盘混凝土的较小拌和量不宜小于25L。
 
*二点、搅拌车载泵对混凝土软硬程度的要求试配时，首先应进行试拌，先查看拌合物自密实功能必控目标，再查看拌合物自密实功能可选目标。当二手搅拌拖泵试拌得出的拌合物自密实功能不能满意要求时，

应在水胶比不变、胶凝资料用量和外加剂用量合理的准则下调整胶凝资料用量、外加剂用量或砂的体积分数等，直到契合要求停止。应根据试拌成果提出混凝土强度实验用的基准合作比。
 
*三点、搅拌车载泵对混凝土软硬程度的要求混凝土强度实验时至少应选用三个不同的合作比。当选用不同的合作比时，其间一个应为本规程*5.2.2条中*2款断定的基准合作比，

别的两个合作比的水胶比宜较基准合作比别离添加和削减0.02;用水量与基准合作比相同，砂的体积分数可别离添加或削减1%。
 
*四点、制造搅拌车载泵对混凝土软硬程度的要求混凝土强度实验试件时，应验证拌合物自密实功能是否到达规划要求，并以该成果代表相应合作比的混凝土拌合物功能目标。
 
*五点、搅拌车载泵对混凝土软硬程度的要求混凝土强度实验时每种合作比至少应制造一组试件，规范维护到28d或规划要求的龄期时试压，也可一起多制造几组试件，

按《前期推定混凝土强度实验办法规范》JGJ/T 15前期推定混凝土强度，用于合作比调整，但终究应满意规范维护28d或规划规则龄期的强度要求。如有耐久性要求时，还应检测相应的耐久性目标。
 
*六点、应根据试配成果对基准合作比进行调整，较后记住二搅拌车载泵对混凝土软硬程度的要求以后的使用比例！
 
English：So we should do the following things for the concrete by using the stirring pump:
The first point, the second-hand mixing pump concrete test should use the original data of the actual use of the project, the minimum mixing volume of the second-hand mixing pump concrete should not be less than 25L.
The second point, when the second-hand mixing and dragging pump is tested, the trial mixing should be carried out first. First, the target must be controlled by the self-compacting function of the mixture, and then the optional target of the self-compacting function of the mixture should be examined. When the self-compacting function of the mixture obtained by the secondary mixing pump is not satisfactory, the volume fraction of the cementation data, the amount of the additive or the volume fraction of the sand should be adjusted under the criteria of constant water glue ratio, reasonable cementitious data dosage and the amount of additive dosage. Until the fit request stops. The reference cooperative ratio for concrete strength experiment should be put forward according to the results of trial mixing.
The third point is that at least three different cooperative ratios should be used in the concrete strength experiment of second-hand mixing and pulling pumps. When choosing a different cooperation ratio, one of them should be this rule
 
总结：依据施工要求，混凝土规划坍落度为120mm~160mm，取单位用水量为215kg，掺加1.7%的缓凝高效减水剂，减水率δ=22%，则混凝土单位用水量:mW0= mW(1-δ)=215×(1-22%)=168kg。
 
English：Summary: According to the construction requirements, the planned collapse degree of concrete is 120mm ~ 160mm, the unit water consumption is 215kg, and 1.7 % of the slow-condensation high-efficiency water reducer is added. The water reduction rate Δ = 22 %. The concrete unit water consumption: mW0 = mW(1-δ) = 215 ×(1-22 %) = 168kg.
