The interface information of the parts is divided into interface parameters and interface shapes. The interface information indicates the corresponding relationship of the parts assembly structure, ensuring that the assembly interface of each part of the gear pump has a uniform size, which can match the size of the entire gear pump without any constraint or interference. . Taking the gear ceramic fiber paper parts of the gear pump as an example to specify the interface information of the components of the gear pump. It consists of a static cylindrical interface (connecting gears and shafts) and a static flat interface (connecting gears and keys).
The modeling of gear pump model is the basis of the rapid design of gear pump. This paper analyzes the structure of gear pump model including geometric model and information model, and uses parametric modeling technology to study the geometric modeling technology of gear pump components. In the information modeling, the part coding information for the component selection and management of the gear pump and the part interface information for the mutual assembly of the parts are mainly studied.
PPGI/PPGL(prepainted galvanized steel /prepainted galvalume steel )is also known as pre-coated steel,color coated steel, coil coated steel, color coated steel,pre pianted steel sheet,The PPGI Steel Coil/sheet made of cold-rolled steel sheet and galvanized steel sheet, subjected to surface pretreatment (degreasing, cleaning, chemical conversion treatment), coated in a continuous manner, and baked and cooled to form a product. Coated steel has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed.
Color coated steel coil is mainly divided into three parts: construction, household appliances and transportation. Building is generally used to build the roof, wall and door of industrial and commercial buildings such as steel structure workshop, airport,warehouse and freezer. Household appliances are used in the production of refrigerators and large air conditioning systems, freezers, toasters, furniture, etc. Transportation industry is mainly used for oil pan, automobile interior parts, etc.
