Classification models divided into vertical and horizontal models models in two forms

Vertical model is widely used today to promote models, design tonnage, yield, wide range of applications; horizontal models because the master cylinder Food dehydrator, seals due to gravity effects, the design pressure increases, the seal the uneven local wear is large, the use of metal scrap briquetting machine models [vertical]
Life is greatly weakened, unable to meet oil equipment continuous use of large production requirements, more use of small tonnage models (design pressure should not exceed 2000KN), a smaller range of applications. Equipment installation engineering acceptance and surrender to use.
