“From January to May, the output value of diamond drills produced by our company has exceeded 100 million, a year-on-year increase of 69%, the highest level in history.†Zhang Wei, director of production planning for Wuhan Drilling Mill of Petroleum Machinery Jiangyan Co., pointed to the data sheet. Analyze the changes in diamond bit yield, equivalent, production value, income, and product structure. In the face of the “cold winter†of the oil bit market and the “adjustment period†of the product structure, in order to improve the market competitiveness, the company has developed a technical plan together with drilling customers through market-based methods to strengthen the research on the ability of bit drilling and other aspects. Aiming at the project team of Fuling shale gas market, a number of on-site service management systems such as personnel stagnation system, patrol system and rapid response system were established, and a package of service commitments was proposed to customers. The sales staff and the technical service personnel are stationed in the well site to cooperate with the customer to carry out the work of standing test, product tracking and business communication. At the same time, the patrolling personnel patrol the well every day, receive the problems or needs reflected by the users, rush to the scene within 15 minutes, the on-site solution can be resolved on the spot, and the team can not solve the problem within the agreed time limit. According to the production progress of each well team, the use of the products, as well as the existing problems, solutions and other content, the weekly report is implemented; for the products that customers urgently need, the on-site service group provides the demand to the product development group, and the product design and production department opens up a green channel. Ensure timely delivery.
Quality service is one of the secrets of opening the diamond drill market. The diamond drill bit is divided into two types: the carcass and the steel body. In this order, the carcass diamond bit stands at 80%. The production process of the carcass diamond drill bit is complicated and the cycle is long, which brings great pressure to the first-line production. In order to ensure smooth production, the company's innovation explores a “seamless connection†production organization, implements an overall operation plan, and shortens the production cycle through lean improvement. Each production team clearly announced the production plan for the next day on the visual panel, including production variety, quantity, processing group, start-up time, completion schedule, corresponding equipment, responsible employees, and user personalized requirements. According to the overall operation plan, the production team flexibly arranged the processing order of the drill bits of each process, and verified the production completion, so that the plan of the day and the completion schedule were unified.
“The proportion of carcass drills last year was only 35%. This year, the proportion of carcass drills has increased significantly, which has brought great difficulties to production scheduling and personnel deployment. In the past, once a weekly production plan was scheduled, the production plan was communicated daily.†You Hongbing, the squad leader of the production workshop of the Wuhan Drill Manufacturing Plant, said.
Busy production motivates employees to innovate and innovate. This year, the company's Wuhan Drill Manufacturing Plant closely contacted the actual production, and applied for a mechanical company improvement project and nine company-level improvement projects, lean improvement activities, from manufacturing, process technology, external processing, cost reduction and efficiency improvement. Start with, improve work efficiency, improve product quality, and reduce labor intensity.
“In the past, we sintered a 6-inch small-sized drill, which can only be sintered at one time. Now, through the improvement of tooling and processing technology, it is possible to achieve multiple sintering of one-time drills, and the work efficiency has also been greatly improved.†Liao Xiaolu, a sintering process employee .
“If the variety is changed during production, it is necessary to re-commission the equipment, which is time-consuming and labor-intensive. Now the last process is to put together the same size products, which saves the debugging equipment time and greatly saves the processing time of the products. "The welding assembly team leader Zhou Qi introduced.
LED magnetic rail is an innovative lighting system that combines LED lighting technology and magnetic technology. It uses magnetic suspension to fix the LED luminaire on the track to achieve convenient installation and positioning.
LED Magnetic Track Lighting has unique advantages. First of all, as a light source, LED has the characteristics of high brightness, low energy consumption, and long life, which can provide energy-saving and environmentally friendly lighting effects. Secondly, the magnetic technology makes the installation and disassembly of the lamp very simple, just align the lamp with the magnetic channel, and it can automatically adsorb and maintain a stable position. This design facilitates the replacement and adjustment of lamps without the use of tools or cumbersome fixing operations.
The LED magnetic track system is suitable for the lighting needs of various places, such as commercial Spaces, home lighting, and office environments. It can be used to illuminate an entire space or highlight specific areas, providing comfortable and even light. Due to the flexibility of the magnetic wiring, the lamps can move and rotate freely along the track to adapt to different lighting angles and needs. In addition, the LED magnetic track also supports dimming and color temperature adjustment functions, and users can adjust the brightness and color of the light according to their needs, creating an ideal lighting atmosphere.Magnetic Rail,Magnetic Track Rail,Magnetic Track System,Magnetic Channel,Magnetic Wiring
