Blister machine (also known as thermoplastic molding machine) is a machine that absorbs heat-plasticized PVC, PE, PP, PET, HIPS and other thermoplastic plastic coils into various shapes of advanced pa

Dry screw vacuum pump, water ring pump, reciprocating pump, slide valve pump, rotary vane pump, Roots pump and diffusion pump, etc. These pumps are the indispensable main pumps in the application of v

Research on the sealing requirements of the vacuum pump system: when the vacuum pump is in the limit state, the water discharged from the first stage is very little, sometimes even no water. Therefore

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

Influence of steam: The commonly used vacuum pump is a steam jet vacuum pump, which uses over-saturated water vapor as the working medium. The condition of the steam has a decisive impact on the funct

For a single-stage vacuum pump, the most easily worn part is the steam nozzle. After the nozzle is worn, it will not only affect the performance of the pump, but also increase the operating cost of th

The environmental impact mainly refers to the pollution of the system by the pumped gas. During the disposal of molten steel, the molten steel will release a lot of gas, and at the same time, some sma

Research on the sealing requirements of the vacuum pump system: when the vacuum pump is in the limit state, the water discharged from the first stage is very little, sometimes even no water. Therefore

Research on nozzle requirements: Nozzle is an important part that affects the performance of vacuum pump. The existing problems are: wrong nozzle installation, crooked installation, blockage, damage,

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 rapid
