Extech Dezhou United Petroleum Machinery Co., Ltd. XTPDM project application case

1 Introduction

Dezhou United Petroleum Machinery Co., Ltd. was founded in 1961, producing all kinds of oil drilling equipment, tools and accessories. Many products have obtained national patents and have independent import and export rights. The DT (De probe) series products produced by the company have high reputation in major oil fields. The products cover all domestic mainland oil fields and are exported to many countries and regions. The company has excellent manufacturing and testing equipment and obtained DNV ISO9001 certification. And API product certification.

2 Project determination

With the development of enterprises and the popularization of computer technology, enterprises are increasingly using computers for enterprise management, product development, processing and manufacturing activities. Product information in the enterprise is growing rapidly, but this large amount of electronic information is usually stored in a local hard disk or a common file server, which makes it impossible for enterprises to share information, security, data validity, version, process monitoring, and system. Effective management such as integration. Therefore, an integrated management system is needed to manage and control various data, data flows and workflows in the enterprise, so as to fully utilize the functions of the computer system and ensure the rapid and efficient development of the enterprise product development process. Product Data Management (PDM) is a software-based technology that manages product-related information and product-related processes. It can meet the management of information related to enterprises and products. Therefore, Deshi Machinery and Extech signed a PDM implementation contract.

3 Enterprise needs analysis

Although the company has formulated corresponding filling specifications, due to the rapid development of the enterprise and the large amount of market orders, the design tasks of the designers are heavy, so the implementation of the specifications is not effectively guaranteed. It is reflected in the title bar of the 2D drawings and the style of the schedules is not uniform. There are no drawings or drawings with unique parts in the individual schedules, which affects the collection of drawing data by the system; the filling of materials and purchased parts cannot be unified, especially the materials reflected in the drawings, in procurement, Another aspect of the warehouse management process uses inconsistencies, affecting the procurement, picking, assembly, etc. in the production process, and is not conducive to reducing inventory and cost.

The technical documents of Deshi Machinery include drawings, various documents, craft cards and so on. How to manage various documents is a difficult point in current computer management. Now according to the customer's order, a new product is obtained through the variant design on the basis of the basic product. The reuse rate of the drawing is quite high. At present, the file management function of the WINDOWS operating system is inconvenient to query and browse through the shared folder. It is impossible to perform efficient data sharing and permission control.

In the enterprise, the design changes of mechanical products are usually carried out by filling out the change order, including: changing the order number, involving the parts, issuing the department, changing the content description, etc., and need to go through the approval signing process, and finally send it to the relevant department. , to make blueprint changes. In the change of electronic drawings, there is a lack of control, which is grasped by the designers themselves and there is no approval for electronic drawings. For borrowed items, it is difficult to deal with the association change problem, and a large number of new parts are used for replacement. The review of the change order is not intuitive, and it also affects the borrowing of the later product design.

The product development cycle is short, there are many projects, and the review process and quality control need to be strictly controlled. Although the ISO9000 and API quality systems have detailed regulations on the new product development process, it is difficult to achieve strict and accurate monitoring and coordination of the project process by means of manual management, which leads to the implementation of these quality systems. The execution of design tasks relies on meetings, telephone conversations, and is not associated with design output, and no effective project management tools are applied. At present, it is difficult to achieve the division of tasks, task prompts, process monitoring, and process records for project design tasks by means of manual management.

4 Project implementation objectives

Realize the management of products: establish an electronic database of parts and documents, electronic data is organized according to the product structure tree, and manage its version; realize fast retrieval, query and browse report output of archived data warehouse; Under the security rules of roles and data ownership, data sharing between graphs and documents is realized.

Timely understanding and monitoring of the entire change process, managing component change versions and change history. Manage component change orders. Change message quick notifications and sign-off feedback. It is convenient to query for existing changes.

According to the research and development process of the existing products, establish a suitable management process; standardize and classify the product data generated by the design process; standardize the document document signing process and change management process; for the project role, organization, data The state sets the corresponding management authority, establishes a secure information access model, and centrally manages the archived data to improve the data security management mechanism.

Shaft / Spindle

A shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power.[1] The various members such as pulleys and gears are mounted on it.
