Analysis of the Industrial Application of Pressure Gauges in Blowers and Vacuum Pumps

As a key monitoring tool for industrial equipment, pressure gauges undertake the core function of real-time monitoring of pressure parameters in systems such as blowers and vacuum pumps. Their application value spans the entire lifecycle of equipment operation.

1. Real-time Operational Status Monitoring and Fault Warning
Pressure gauges accurately reflect equipment load conditions by measuring the pressure difference between inlet and outlet pipelines. Taking Roots blowers as an example, when the pressure gauge shows an abnormal increase in outlet pressure, it may indicate pipeline blockage or aerator head scaling, requiring timely cleaning to avoid motor overload; if the inlet pressure of a vacuum pump consistently falls below the set value, it may suggest a leak in the vacuum pipeline, necessitating inspection of sealing components. A steel enterprise successfully reduced unplanned downtime caused by pipeline blockages by 70% by installing pressure gauges on the balance pipes of gas blowers.

2. Dynamic Regulation of Process Parameters
In the semiconductor manufacturing sector, vacuum pump pressure gauges are linked with PID control systems to stabilize chamber vacuum within a range of ±0.5Pa, ensuring the uniformity of photoresist coating. In the food packaging industry, feedback data from pressure gauges are used to automatically adjust the suction rate of vacuum packaging machines, reducing the residual oxygen concentration in packaging bags to below 0.3% and extending product shelf life.

3. Construction of a Safety Protection System
Pressure gauges utilize electrical contact devices to enable automatic alarms for overpressure/underpressure conditions. A chemical enterprise's chlorine gas transmission system employs a redundant design with dual pressure gauges. When any gauge detects pressure exceeding 1.2MPa, it immediately triggers the emergency pressure relief valve, preventing pipeline burst incidents. The linkage control between pressure gauges and vent valves allows Roots blowers to quickly unload during sudden load changes, preventing rotor seizure.
