Research on Vacuum Pump of Blister Machine

Research on working steam and its dryness: low steam pressure and pressure fluctuation have great influence on the capacity of vacuum pump, so the steam pressure should not be lower than the required working pressure, but the structure design of the vacuum pump used has been finalized, too much increase Steam pressure does not increase pumping capacity and vacuum. In addition, to ensure that the steam pressure supplied by the boiler is stable, it is best to use a boiler to provide working steam to the steam jet pump, so that the steam pressure will not fluctuate and the performance of the vacuum pump will be stable.

Research on the requirements of circulating cooling water: insufficient cooling water supply, the condenser will heat up, the sound of the airflow will become louder, the vacuum degree will drop rapidly, and even the steam will return to the exhaust pipe. Condensed water plays a pivotal role in multi-stage vacuum pumps. Condensed water can fully condense steam. The partial pressure of water vapor in the discharge pressure of the vacuum pump must be higher than its corresponding saturated vapor pressure, so the temperature of the condensed water should also be lower than The full temperature under this pressure can ensure the normal operation of the pump body.
