摘　　要：阐述屏蔽泵性能参数(流量、扬程、效率)的测试与计算方法,以实际产品测试数据为例,说明扬程修正的必要性。以两屏蔽泵样品为例,比较耐久前与耐久后的扬程和效率。分析屏蔽泵效率低的原因,提出改进措施。The test and calculation methods of performance parameters including flow rate, head and efficiency of canned motor pump are described. Taking the actual product test data for example, the necessity of head correction is illustrated. Taking two canned motor pump samples for example, the head and effi- ciency before and after the durability test are com- pared. The reasons for low efficiency of canned motor pump are analyzed, and the improvement measures are put forward.
