In the pharmaceutical industry, the safety of pharma centrifuges is of paramount importance, especially when handling flammable and explosive materials. Effective explosion-proof safety measures can reduce the risk of accidents and protect the safety of operators and equipment. This article will focus on the explosion-proof safety technical measures of pharma centrifuges, including preventing the formation of combustible gases, eliminating ignition sources, isolation and blocking, and effective monitoring.
When using pharma centrifuges to handle flammable and explosive materials, it is first necessary to ensure the tightness and explosion-proof performance of the centrifuge. When the centrifuge is filled with combustible gas, if a static spark or other ignition source appears, it may cause a serious fire or explosion. Therefore, when designing pharma centrifuges, the use of inert gas protection should be considered, such as filling the centrifuge with nitrogen to maintain a safe oxygen concentration. Generally, the oxygen concentration should be controlled between 1% and 2% to ensure safety.
Before starting the industrial centrifuge separator, gas replacement must be carried out to ensure that the oxygen concentration meets safety requirements. In addition, the solution in the centrifuge should be protected by nitrogen during liquid intake to prevent air from mixing in. The stability of the nitrogen system also needs to be strictly monitored. If there is insufficient pressure or system failure, the alarm device will issue a warning and automatically stop the machine. Especially when modifying existing pharma centrifuges, online oxygen detection systems and interlock protection devices should be established to avoid explosion accidents caused by operational errors.
Potential sources of fire or explosion include open flames, high-temperature surfaces, friction, and impact. The design of pharma centrifuges must fully consider these factors, ensuring that moving parts have enough safety space to prevent mechanical friction and impact from producing sparks. At the same time, the pharma centrifuge should have measures to eliminate static electricity to reduce the risk of static sparks.
When selecting pharma centrifuges, special attention should be paid to equipping explosion-proof motors, explosion-proof solenoid valves, and anti-static belts and other safety devices. Enterprises should also formulate strict on-site safety management regulations to ensure that workers do not use mobile phones, lighters, and other items that may cause fire sources in the centrifuge operation area. In addition, the workplace should regularly conduct lightning protection and anti-static testing to ensure overall safety.
To enhance the safety of pharma centrifuges, enterprises should establish a comprehensive monitoring system. Install combustible gas and toxic gas detection alarm devices in the centrifuge operation area to monitor gas leakage in real-time and interlock with forced ventilation facilities. Once a leakage is detected, the alarm system will immediately activate, ensuring timely elimination of safety hazards.
In addition, the technology of pharma centrifuges is constantly improving. The application of online oxygen detection devices and pressure transmitters allows real-time monitoring of oxygen concentration, keeping it within a safe range. The introduction of intelligent automatic control technology has significantly enhanced the safety and automation of the centrifuges. By implementing quantitative control and automatic alarm mechanisms, safety accidents caused by operational errors can be effectively reduced.
