Since the "Quality Month" in 2024, Jichai Power Co., Ltd. has closely adhered to the theme of "strengthening quality risk prevention and promoting high-quality development", firmly established the concept of "quality is the life of enterprises, quality is efficiency", unified deployment and strengthened execution, and fully promoted the continuous improvement of employees' quality work ability and risk prevention awareness, laying a solid quality foundation for the construction of a world-class energy and power equipment enterprise worth billions of yuan.
Training and enhancing military skills
A quality awareness that is deeply ingrained in the mind, proficient and solid production skills, and rich and comprehensive work experience are the key to enhancing the quality awareness and ability of all employees. In recent days, Jichai Power has urged and guided all production and operation units to actively carry out quality training and job training, using quality improvement to drive the improvement of quality level.
In terms of engine heat treatment, Jichai Power has focused on "measurement of nitriding crankshaft runout" and carried out job training activities, further deepening the understanding of frontline operators on the impact of crankshaft nitriding stress on deformation, and achieving dual improvement of employee quality awareness and product physical quality.
At the compressor manufacturing base in Xinjiang, Jichai Power organized practical training on compressor operating condition software calculation, DTY315 compressor three-stage high pressure ratio alarm, and Harbin Yilian compressor vibration high fault handling. The main means of teaching operation methods and exercising work skills effectively improved the "hard power" of compressor products.
Anticipate and prevent risks in advance
Stable quality is an important support for the survival and development of enterprises. In order to further enhance risk prevention awareness and promote the steady improvement of product quality, Jichai Power, in combination with its production and operation reality, conscientiously pre predicts and intervenes in the resolution of quality problems and hidden dangers.
In terms of processing engine casing components, the company has taken into account the recent high number of variant machines for 4006 and 4008 products, combined with past quality work experience, and has done a good job in organizing, classifying, and analyzing production drawings in advance, avoiding the high error rate of processing dimensions caused by the variety of models, and making the processing quality "immediately" improve. At the same time, in response to the frequent occurrence of bumps and scratches during the lifting process of the machine body, the enterprise has designed and produced end face corner protection fixtures, effectively improving the appearance quality of the product.
In terms of engine assembly testing, Jichai Power focuses on 10 "flagship products" such as 20V190 and 12V175, and organizes and sorts out typical and common quality problems that occur in production and application sites. Starting from assembly, complete sets, testing, painting and other links, detailed quality hazard risk analysis is carried out, and a sales rectification operation table is classified and formulated. More than 20 quality improvement plans are proposed and implemented, effectively solving the problems of difficult assembly of water pipes in the cooling system of gas engines. The improvement effect has been recognized by employees and users.
Manufacturing upgrade ensures stable quality
The process flow and operating procedures are the key to ensuring production quality and product quality. During the "Quality Month" period, Jichai Power organized a special action to upgrade and create excellence from top to bottom, comprehensively creating reliable and stable product quality.
In the field of new intelligent equipment formats, Jichai Power has solidly optimized the drawings and processes of fuel dispenser products, strictly implemented assembly processes, test outlines, and inspection regulations, and completed the construction of two "quality management points" for fuel dispenser products. The company has also established a mechanism for tracing the source of quality issues with fuel dispensers, continuously safeguarding the quality of fuel dispenser products.
In the engine assembly workshop, Jichai Power has carefully sorted out the key points of quality control in the sled mounted machine room for key processes. Focusing on important items such as the appearance, welding, sandblasting, and painting of the machine room, "form based management" has been implemented to ensure that quality responsibilities are properly controlled and assigned to individuals; We have launched a special action to improve cleanliness and further strengthen the control and implementation of the complete quality inspection process; Targeted improvement of product process standardization, strengthening technical support for key projects of enterprises, organizing complete sets of processes for computer rooms, improving solidification operation manuals, and effectively controlling product quality levels.
Supervision, inspection, and strong control
Only by continuously conducting quality inspections and reviews, efficiently eliminating recurring quality problems, can we make up for shortcomings, strengthen the foundation, and further improve the overall quality of the enterprise. Jichai Power focuses on key project products and issues discovered during early quality audits and inspections, focusing on four aspects to comprehensively carry out product quality inspection, rectification, and problem closure work.
One is to increase supervision and inspection efforts and targeted sampling, implement supplier level full life cycle control for purchased parts, strengthen the frequency of incoming sampling, production site inspection efforts, supplier quality assistance, on-site supervision and inspection, and other measures to ensure the qualified rate of purchased parts entering the warehouse. The second is to strictly enforce quality penalties, strengthen closed-loop management of problems, and resolutely eliminate suppliers with repeated quality problems and poor supply guarantee capabilities. The third is to strengthen the normalized docking of quality business with design, marketing, procurement, production units and suppliers, and improve the on-site problem resolution rate. The fourth is to fully implement the form based management mode of "operating according to orders, checking according to orders, and assessing vouchers", optimize and revise forms such as the "Quality Problem Correction and Prevention Notice", standardize the quality problem handling process, ensure that there is a legal basis for on-site inspection in production, and continuously promote the improvement of enterprise quality control work.
'Excellent quality' is the inherent manufacturing gene of Jichai Power, which has built a solid foundation and dam for the enterprise to overcome storms for a hundred years, and is also an important guarantee for achieving its goals in the new era and new journey. The quality management department of Jichai Power stated that the company will further summarize its experience, optimize measures, and take the launch of the "Quality Month" activity in 2024 as an opportunity to solidly and consistently do a good job in quality work tasks, promote the construction of a "quality strong enterprise", and promote the high-quality development of the enterprise with high-quality "two machines and two new" products.
