| titleOfInvention | A dry vacuum system with a condenser in front of the pump |
| abstract | The invention belongs to the field of dry vacuum pump systems, in particular to a dry vacuum system containing a condenser in front of the pump. The system includes a vacuum pump unit and a pre-pump condensing unit, the pre-pump condensing unit includes a pre-pump condenser, and the pre-pump condenser includes five ports; the first port of the pre-pump condenser passes through a material inlet pipe and a vacuum material inlet Connection, the second port is connected to the vacuum pump unit through the first material pipe, the third port is connected to the condensate discharge pipe, the fourth port and the fifth port are connected to the third port through the third frozen brine outlet pipe and the third frozen brine inlet pipe respectively. The frozen brine outlet is connected to the third frozen brine inlet. The invention provides a dry vacuum system including a condenser in front of the pump. In the system, the condenser in front of the vacuum pump is set up as a trapping unit for condensable gas, which improves the phenomenon of water accumulation in the vacuum pump and pipeline. |
