How long can the screw press run?
The maximum operating time of the screw air compressor is affected by many factors and can be continuously operated for several months to several years under ideal conditions, but the following key factors need to be combined in practice:
of maintenance plan
Lubricating oil replacement: oil lubrication models need to change oil every 4000-8000 hours, if overdue may lead to lubrication failure or high temperature shutdown.
Filter element replacement: air filter and oil filter clogging will limit the air intake, so it needs to be cleaned or replaced regularly (usually every 1000-2000 hours).
Overhaul period: It is recommended to check bearings and seals every 20,000-30,000 hours to avoid sudden failure.
-
Temperature/humidity: high temperature environment needs to strengthen cooling (such as adding cooling fan), high humidity needs to match the dryer.
-
Air quality: Dusty environment needs to shorten the air filter replacement cycle to prevent dust from entering the compression chamber.
2. Operating environment
- of
-
Intermittent operation: frequent start and stop may lead to motor or control system failure, it is recommended that continuous operation is more stable.
3. Load and working condition
Sustained high load: Long-term full load operation may accelerate bearing wear, vibration and temperature monitoring are required.
-
Efficiency decay: energy consumption of old equipment may increase by 20%-30%, and replacement costs need to be evaluated.
4. Design Life
Industrial-grade models usually have a design life of 8-10 years, and high-quality brands can reach more than 15 years.
5. Monitoring and early warning
Smart sensors monitor temperature, pressure and vibration in real time and give early warning of potential failures.
Shutdown inspection: even if there is no fault, it is recommended to shut down at least once a year for a comprehensive inspection.
- for
actual case reference
Best practice: a pharmaceutical screw air compressor through strict maintenance (every 8000 hours oil change, quarterly inspection), continuous operation for more than 5 years without overhaul.
-
Common reasons for shutdown: bearing stuck (about 30%), insufficient cooling (25%) and electrical failure (20%) due to failure to change oil.
Summary
the screw press can run continuously for many years under standard maintenance, suitable environment and reasonable load, but it needs to be shut down regularly for maintenance. It is recommended to develop a preventive maintenance plan to avoid the risk of sudden downtime caused by “no bad repair. If the pursuit of extreme reliability, can be configured to use the standby unit rotation.
