Vacuum Negative Pressure System

The system has stabilivolt, steam strain, oil and gas distribution, steam-water separation and other functions, the main effect is to make the dry sand tight and solid in the process of casting pouring, and take the gasification product out the cavity timely to get sound casting. Vacuum negative pressure system is one of the main core equipment used in dry sand negative pressure expendable pattern casting process, the negative pressure units designed and manufactured by Xinhai casting has changed into whole table type instead of early separate-type, which has simple and compact structure, easy to install and maintain, and also reduce the pipeline resistance when extracting vacuum, improves the equipment efficiency. It adopts independent negative pressure control cabinet, control the action of negative pressure unit, make the negative pressure unit produce vacuum in accordance with the requirements of the casting process, and the negative pressure divider distribute the vacuum that produced by negative pressure units reasonably, and then distribute to each vacuum point which needs vacuum. Feature

Equipment Characteristics

The system is economical and practical, it has simple and compact structure, easy to install, easy to maintain, at the same time, it can also be used for other industries that need to extract vacuum.
