The utility model relates to the field of concrete preparation machinery, in particular to a water feeding system of a concrete mixing station, which comprises a water tank, on which a main conveying pipe is connected, a main water pump is arranged on the main conveying pipe, on which a auxiliary conveying pipe is also connected, on which a auxiliary water pump is arranged, the diameter of the main conveying pipe is larger than the auxiliary conveying pipe, and a water scale, a auxiliary conveying pipe and a main conveying pipe are arranged above the water tank The delivery pipes are all connected with the water scale. The main delivery pipe is equipped with a number of slow flow devices. By setting the main delivery pipe and the auxiliary delivery pipe, the main water pump and the auxiliary water pump can be turned on at the same time to deliver water to the water scale. When the water in the water scale is close to the calibrated water volume, the main water pump will be turned off and the auxiliary water pump will continue to be turned on. The water will be accurately delivered to the water scale through the auxiliary delivery pipe A number of slow flow devices are set on the main conveying pipe to reduce the vibration and impact caused by water backflow when the main water pump is closed. The whole device has fast water feeding speed, small water feeding deviation and small impact.

一种混凝土搅拌站上水系统
本技术涉及混凝土制备机械领域,尤其是涉及一种混凝土搅拌站上水系统。
技术介绍
近年来,随着搅拌站集成优化设计的加强,节能环保性能的不断提高,对供水系统提出了越来越多的要求,除了满足输送生产供水外,还增添了皮带清洗、接料槽清洗以及搅拌车清洗等供水要求。在混凝土搅拌站中,供水系统是其重要的组成系统,也是影响整个搅拌站生产率的重要因素,市场对混凝土的配比精度要求也是越来越高,供水系统是否及时、准确的将水补给到搅拌主机内对拌合精度和效率有较大的影响,现有的供水系统很难对水的精度进行控制,从而无法保证混凝土配比精度的准确性。如公告号CN202781450U的中国专利公开的一种搅拌站上水系统,包括电机、水泵、连接管、水秤和传感器,所述的电机与水泵相连接,水泵通过连接管与水秤相连接,水秤上表面焊有传感器,由于水由电机和水泵直接送到水秤。但是,上述技术存在以下缺陷:其水秤在称量完所需水量后,上述水泵停止运转,此时连接管中的水便会依靠自身重量回流,引发连接管震动,这种不断的震动极易引发连接管焊缝开裂, ...
