井用潜水电泵是潜水电泵的一种,用于从水井中抽取清水。它与深井泵(长轴井泵)相比具有结构紧凑、安装操作简便、工作可靠和效益高等优点,广泛应用于国民经济生产的各部门。1 井用潜水电泵的型号井用潜水电泵有许多类型和规格,为便于潜水电泵的生产和使用,国家制定了统一型号,用拼音字母和数字表示其结构特征、使用要求及工作性能等。井用潜水电泵用QJ表示,如300Q125-110/5,各组成部分的含义是:①300表示泵适用的最小井径是300mm;②QJ表示井用潜水电泵;③125表示泵的额定流量是125m~3/h;④110表示泵的额定扬程是110m;⑤5表示泵的级数为5级,即装有5个叶轮。把不同型号井用潜水电泵的基本工作参数列于一个表中,就形成了井用潜水电泵的选型表。
Submersible pump is a submersible pump used to draw water from the well. Compared with the deep well pump (long axis well pump), it has the advantages of compact structure, easy installation and operation, reliable operation and high benefit, and is widely used in various departments of national economy production. 1 submersible pump with a well model Submersible pump with many types and specifications, in order to facilitate the production and use of submersible pump, the state has developed a unified model, with pinyin letters and numbers that its structural characteristics, the use of requirements and performance Wait. Well submersible pump with QJ, such as 300Q125-110 / 5, the meaning of the components are: ① 300 means that the minimum diameter of the pump is applied 300mm; ② QJ wells with submersible pump; ③125 that the pump rated flow is 125m ~ 3 / h; ④ 110 represents the pump rated head is 110m; ⑤ 5 that the pump level is 5, that is equipped with five impeller. The different types of wells with submersible pump basic working parameters listed in a table, it formed a well with submersible pump selection table.
