Why do many companies use compressed air at 7 bar pressure and above in their processes?
Compressed air systems are widely used for their ability to deliver high energy efficiently, which can compensate for various system inefficiencies and provide robust operation across multiple applications.
What challenges arise with low pressure vacuum and blower systems compared to high-pressure systems?
Low pressure systems, operating around 1 bar positive or negative pressure, require precise management as they have less energy to overcome system inefficiencies, making them sensitive to even minor changes.
TROUBLESHOOTING & TECHNICAL SUPPORT
What are common issues encountered in low pressure systems?
Issues in low pressure systems often stem from human error or process issues, requiring a detailed and methodical approach to troubleshoot effectively.
Why is troubleshooting low pressure systems more complex than high pressure systems?
Troubleshooting low pressure systems often requires thinking "outside the box" and a deep understanding of the entire system's dynamics, as the problems might be symptomatic rather than causal.
ROLE OF SERVICE TECHNICIANS
How do the roles of low pressure service technicians differ from high pressure compressor technicians?
Low pressure technicians often act as system engineers, needing to assess the entire system and environment, rather than just focusing on the equipment. This includes evaluating changes in system setup, operational practices, and environmental conditions.
COMMON FAULTS AND MAINTENANCE CHECKS
What are common faults found in vacuum and pneumatic conveying systems?
Common issues include extended delivery lines, modified pipework, malfunctioning valves, blockages, and environmental changes affecting system performance.
What maintenance checks are essential for low pressure systems?
Routine checks include assessing service records, oil levels, filter conditions, belts, pulleys, motors, coolers, and fans to prevent system failure and ensure operational integrity.
ADDITIONAL TECHNICAL FAQS
How do ambient conditions affect low pressure systems?
Ambient conditions like temperature and air quality can significantly impact system performance, particularly for systems sensitive to changes in operating environments.
What steps should be taken if a blower or vacuum pump fails?
Initial steps include a thorough inspection of the system to determine if the issue is symptomatic of a larger problem, followed by checks on common fault areas like pipework and mechanical components.
Why is it important to regularly update the maintenance record of low pressure systems?
Maintaining an up-to-date record helps in early detection of potential issues, ensures compliance with safety standards, and prolongs the life of the equipment by timely addressing wear and tear.
