在城市规划建设基本建设地面、道路公路桥梁、房屋、混凝土搅拌站以及水利水电工程工程项目中,混凝土搅拌站车可谓是不可或缺的运送常用工具,十分是自动搅拌一体机,因其具有车身窄、轴距短等情感化设计计划方案特点,因而对高度限制、宽、长的工作环境有很强的运用优势。那么,功能完善的自动搅拌一体机到底是如何工作上的呢?
In the urban planning and construction of capital construction ground, roads, bridges, houses, concrete mixing plants and water conservancy and hydropower projects, the concrete mixing plant truck is an indispensable and common tool for transportation. It is an automatic mixing machine. Because it has the characteristics of emotional design plans such as narrow body and short wheelbase, it has restrictions on height, width Long working environment has strong application advantages. So, how does the fully functional automatic mixing machine work?
自动搅拌一体机基本原理是由汽车底盘提供推动力来控制器液压传动系统系统软件的变量柱塞泵,把机械设备机械能转成四柱液压机能传送给定性分析电动机,接着再将依据减速机拌和筒转动,从而对混泥土进行强制拌和,使它在独特时间内不易凝固。由于其上述的工作上特点,一般根据对混泥土运送间隔的长短、工程施工施工工地规范以及对混泥土质量和配置不一样情况的要求,一般选用2种不一样工作方式。
The basic principle of the automatic mixing machine is that the vehicle chassis provides the driving force to control the variable plunger pump of the hydraulic transmission system software, convert the mechanical energy of the mechanical equipment into four column hydraulic function and transmit it to the qualitative analysis motor, and then rotate the mixing drum according to the reducer, so as to forcibly mix the concrete, so that it is not easy to solidify in a unique time. Due to the above working characteristics, two different working methods are generally selected according to the length of concrete transportation interval, engineering construction site specifications and the requirements for different concrete quality and configuration.
1.预拌混凝土的拌和运送。将在混凝土搅拌站拌和好的混泥土马上放进混凝土搅拌车中运送,在自动搅拌一体机运送半途,拌和筒大约以1~3r/min传动比转动,使筒内混泥土不断拌和,避免 混凝土裂缝情况,以保证混泥土质量。这类方法运送混泥土的间隔不宜过长,一般控制在混泥土初凝以前,根据混泥土配置和交通路况、平均气温等规范可定好间距或时间。
1. Mixing and transportation of ready mixed concrete. The concrete mixed in the concrete mixing plant is immediately put into the concrete mixing truck for transportation. Halfway through the transportation of the automatic mixing machine, the mixing drum rotates at a transmission ratio of about 1 ~ 3R / min to continuously mix the concrete in the drum to avoid concrete cracks and ensure the quality of concrete. The interval of transporting concrete by this method should not be too long. It is generally controlled before the initial setting of concrete. The interval or time can be determined according to the concrete configuration, traffic conditions, average temperature and other specifications.
2.混泥土搅拌料的拌和运送。一般有2种情况:颗粒物料和水料拌和运送。颗粒物料注水拌和运送:在调味品站将石料、混泥土等颗粒物料按混泥土配置加上拌和筒内,再将拌和饮用水加上车内储储水箱,在半途适当的间隔或时间将水喷入筒内,对混泥土进行拌和,也可去施工施工工地后拌和。水料拌和运送:在调味品站将石料砂石料、混泥土和水等搅拌料按配置此外放进拌和筒内,拌和筒在运送半途以8~12r/min的传动比转动,对搅拌料进行拌和,开展拌和工作中。
2. Mixing and transportation of concrete mixing materials. Generally, there are two situations: mixing and transportation of granular materials and water materials. Water injection, mixing and transportation of granular materials: add granular materials such as stone and concrete into the mixing drum according to the concrete configuration in the condiment station, and then add the mixing drinking water into the internal storage tank. Spray water into the drum at appropriate intervals or time on the way to mix the concrete, or go to the construction site for mixing. Mixing and transportation of water materials: put the mixing materials such as stone, sand and stone, concrete and water into the mixing drum according to the configuration in the condiment station. The mixing drum rotates at the transmission ratio of 8 ~ 12R / min during the transportation to mix the mixing materials and carry out the mixing work.
上述2种方式比照,前边一种更能提升对混泥土的运送時间或间隔。还有一种方式是从某种程度上来讲,自动搅拌一体机基本替代了混凝土搅拌站的作用,为应用人既节省了机械设备投资项目,又提高了生产率。但是,在混泥土粘结力,均匀等质量上存在着难点,不象混凝土搅拌站生产加工的混泥土那样好。因而,为保证混泥土的质量,考虑到当今基建项目建筑施工的要求,另一种工作方式变成了目前自动搅拌一体机的甄选工作方式。
Compared with the above two methods, the former one can better improve the transportation time or interval of concrete. Another way is that to some extent, the automatic mixing machine basically replaces the role of the concrete mixing plant, which not only saves the investment projects of mechanical equipment, but also improves the productivity for the users. However, there are difficulties in the quality of concrete adhesion and uniformity, which is not as good as the concrete produced and processed in the concrete mixing plant. Therefore, in order to ensure the quality of concrete, considering the requirements of today's infrastructure project construction, another working mode has become the current selection working mode of automatic mixing machine.
当然,要想更各个方面地充分运用自动搅拌一体机的功效和优势,进熟悉混凝土搅拌车的基本原理仍是不够的,更重要的是掌握适当操作流程,并提高对混凝土搅拌车的维修保养和检查维修,仅有那般才能够保证混凝土搅拌车从始终运行状态。
Of course, in order to make full use of the functions and advantages of the automatic mixer in all aspects, it is still not enough to be familiar with the basic principles of the concrete mixer. What is more important is to master the appropriate operation process and improve the maintenance, inspection and repair of the concrete mixer. Only in this way can we ensure the operation state of the concrete mixer from beginning to end.
