Performance Test And Analysis Of Electric Drill J1Z-13

With the deepening of China's reform and opening up,the electric tools industry has developed rapidly.At the present stage,the main body of the industry is joint-stock enterprises and private enterprises.The development and design ability of the industry has reached an ideal level,and it can produce more than 300 varieties and more than 1500 Standard electric tools.In recent years,the technology of electric tool products has been optimized in China,and diversified new products have been designed.But on the whole,besides the products made by foreign-funded enterprises,the level of electric tools manufactured in China is obviously low at this stage.The key point is that the power tools are low in output and relatively high in noise,which will produce a strong sense of fatigue after being used for a long time.The data of the Shanghai electric tool test station shows that in the durability test,the one-time inspection rate of domestic products is only 85%-90%,and the imported goods are more than 95%.Carbon powder deposition often occurs in China's electric tools.After continuous work,a large amount of carbon powder will be accumulated on its inner wall and around the fixed rotor,and there is often no trace of any carbon powder in the imported product.As consumers have more stringent requirements for the quality of products,most enterprises attach great importance to the quality of products,and design a standard to match all kinds of products.Under this premise,strict quality testing is carried out to ensure that the quality of products can reach a higher level.In this paper,an electric drill jlz-13 is used as an example to detect and analyze the performance of the electric drill,and analyze and study in seven chapters.The first chapter is the introduction,which mainly elaborates the development status of electric tools at home and abroad,the development status of power tool performance testing and the main research contents of this paper.The second chapter is the overall scheme design of the electric drill jlz-13 test,and introduces the outline of the electric drill test project and the plan of the detection scheme.Chapter iii for drill electrical performance testing analysis,mainly from the nameplate normative,starting test,input power test and IPXO moisture resistance test and so on four aspects,this paper expounds the electric drill nameplate power test,and in view of the electric drill electric performance is optimized design;The fourth chapter is the detection and analysis of the temperature rise performance of the electric drill.It mainly studies the heating test of the electric drill and analyzes the uncertainty of the heating,and finally optimizes the temperature rise performance of the electric drill.Chapter 5 for drill comprehensive performance testing and analysis,and in the case of working condition of electric drill light,durable,and the durability test was studied for the electric drill,but also from the power cord type and intensity of test research,finally,the comprehensive performance of electric drill is optimized;The sixth chapter is the performance test and analysis of the electric drill material,mainly studied the heat resistance and flame retardation of the electric drill,and the most electric drill material has been designed and optimized;Chapter seven is the conclusion and prospect,the main performance criteria and evaluation method for combining electric drill safety,from electric drill electric performance,temperature performance,comprehensive performance and material performance from four aspects to consider,it is concluded that the electric drill in the nameplate power parameter calibration safe and reliable,good insulation performance,reasonable manufacturing process,reasonable and strength meet the requirements of the power cord type selection,material selection process in accordance with the conclusion of related standards.In a word,to drill a comprehensive performance test system to explore and analyze the valuable significance,and test their product performance requirements,and to drill enterprise and put forward the improvement measures,progress has great practical value to the nation.
