AQSIQ spot checks submersible pumps: unqualified product detection rate of 10.2%
According to the report, in the third quarter of 2015, 59 batches of submersible electric pump products produced by 59 companies in six provinces and municipalities including Tianjin, Hebei, Shanxi, Jiangsu, Zhejiang, and Henan were sampled.
This spot check is based on the requirements of GB10395.8-2006 “Safety Requirements for Tractors and Machinery for Agriculture and Forestry Part 8: Drainage Pumps and Pump Sets†and other requirements for overload protection, grounding measures, insulation resistance, and electric pumps of submersible pumps. The eleven items of cable, stator winding withstand voltage, efficiency, specified point flow and head, power factor, stator temperature rise limit, motor cavity water (gas) pressure test, and safety sign were examined.
Spot checks found that Handan Guangquan Pump Co., Ltd., Xingtai Hongjin Submersible Pump Manufacturing Co., Ltd., Shanxi Sanzhou Pump Co., Ltd., Nanjing Kelaier Pump Co., Ltd., Taizhou Jinchuan Pump Co., Ltd., and Henan Tianyu Pump Co., Ltd. 6 batches of products of 6 companies, such as Industry Co., Ltd., do not meet the requirements of the standard, involving efficiency, electric pump lead-out cables, specified point flow and head, and power factor items.
Among them, the problem of efficiency is outstanding, and 6 batches of unqualified products are unqualified.
In addition, Shanxi Jinjiang Pump Manufacturing Co., Ltd. refused inspection during the spot check.
45 degree elbow and 90 ° elbow , 90 Degree Elbow forming a right angle and 45 degrees is an obtuse angle. Two 45-degree elbows can not be welded into a 90-degree bend to use, because the stress concentration area is the elbow pipe, expansion and most of the stress deformation during cooling are released at the elbow. Also weld itself to be the weak link, fatigue deformation will soon cause cracking damage, which planted a lot of hidden dangers, so do not at immediate convenience, eventually leading to huge losses.
