河南省试制了一种适用于机电井灌区的新型提水工具——“62型”链条泵,经该省科委组织有关部门进行技术鉴定的结果认为:这种水泵整体结构简单、紧凑、牢固,便于调整出水量,维修简便,具有较大的适用范围,效率较高,且耗电量与作业成本较低,在技术上基本成熟,可以初步定型,投入小批生产试用。故本刊特此介绍出来,供有关地区参考。但是文内引用的数据系样机的部分试验成果,有些问题,如链条泵效率的测量精度以及效率与扬程的关系等,还待今后进一步研究论证。
Henan Province trial production of a new type of lifting tools for the electromechanical well irrigation area - “62” chain pump, the provincial Science and Technology Commission organized the relevant departments of the technical appraisal results: the overall structure of this pump is simple, compact, strong , Easy to adjust the amount of water, easy maintenance, with a larger scope of application, higher efficiency, and lower power consumption and operating costs, the technology is basically mature, you can initial shape, put into small batch production trial. Therefore, this article introduced here, for reference to the area. However, the data quoted in this paper are part of the experimental results of the prototype machine. Some problems, such as the measurement accuracy of the chain pump efficiency, the relationship between efficiency and lift, etc., are yet to be further studied and demonstrated.
