Research On The Application Of Work Study In The Production And Improvement Of DF Company's All-welded Ball Valves

Valve in the relationship between the people's livelihood has an important area of great demand,is an important part of the machinery and equipment manufacturing industry,the full welding ball valve in the valve has rapidly developed into a major valve class.Throughout the valve production enterprises,usually the traditional manual-based order-based production model,the production cycle is long,low efficiency,often encounter the challenges of emergency orders.How to set up a set of scientific and reasonable work in line with their own research programs to achieve low investment,high efficiency is sought after by many enterprises.This subject based on DF company full welding ball valve production practice,using all welded ball valve as the research object.First of all,the present situation and existing problems of all-welded ball valves are analyzed from relevant dimensions: PQCDSME(production efficiency,quality,cost,delivery time,safety,morale,environment),to identify the biggest problem is to produce low efficiency,and then find the problem The root cause is the lack of systematic work of the production line research guidance and scientific and reasonable standard working hours system.Secondly,overall improvement program is given about manufacturing all welded ball valves,under the combination of 5W1 H method and ECRS principle,the process of the whole production was analyzed and improved,and the processing times and time were reduced;preassembled and welded the assembly of the key links of the production,analyzed and improved the mobile lines of the production staff and the production process procedures,and reduced the waste caused by handling;on the other key part of welding cone inside and outside the human-machine operation analysis and improvement,improved man-machine utilization,standard operating procedures.Finally,based on the improved production methods and processes of production,to set up the standard time of welding inside and outside the cone and assembly pre-installed and welding.Through the combination of work study and actual production,this subject has helped enterprises to improve production efficiency.At the same time,it provides a model that can be used as a reference for other enterprises in the production sector and their counterparts.
