由兖州煤矿机械厂与山东矿业学院最新联合研制的新型200D43A型矿用清水泵已于1991年12月通过部级技术鉴定。这种新型矿用清水泵是在兖州煤矿机械厂生产多年的200D43泵的基础上修改设计而成的高效、高吸上性能矿用泵。在保证其流量、单级扬程不变的情况下,不仅使效率从原来的78%提高到现在的80%,而且还使吸上性能从原5.7m提高到6.7m。这一重要指标的提高,为井下水仓的布置、容水量
The new type 200D43A mining water pump developed jointly by Yanzhou Coal Mining Machinery Factory and Shandong Mining Institute has passed the ministerial technical appraisal in December 1991. This new type of mining water pump is a high efficiency and high suction performance mining pump which is designed and modified on the basis of the 200D43 pump produced by Yanzhou Coal Mining Machinery Factory for many years. In ensuring its flow, single-stage lift unchanged, not only to improve the efficiency from the original 78% to 80%, but also to suction performance from 5.7m to 6.7m. The improvement of this important indicator for the arrangement of underground water storage, water capacity
