Gear pump actual surveying and mapping combination training device

1Product Overview:

《Gear Pump "actual measurement drawing combinationtrainingdeviceUsing refined small gear pumps as the core surveying object, through entity disassembly, measurement, and drawing training, we help students master core skills such as view expression, dimension annotation, technical requirements, and assembly drawing of fluid mechanical components,includeRefined small gear pump (one unit).

1Storage method: Comes with a hard storage box and built-in positioning slot for easy classification, storage, and carrying.

2Applicable scenarios: Classroom and post class practice of the course "Mechanical Drawing" for mechanical majors in universities and vocational colleges.

3Strong comprehensiveness: using gear pumps as carriers, integrating knowledge from multiple aspects such as gear transmission, fluid sealing, precision assembly, etc., to achieveIntegrated teaching of theory, reality, and virtuality.

4Typical structure: It includes typical mechanical design elements such as involute gears, pump body seals, and shaft support, which facilitates students' understanding of the working principles and expression methods of fluid machinery.
