Hey there! As a supplier of Screw Type Air Compressor, I've seen my fair share of air compressors in action. One of the most important things that often gets overlooked is how to shut down these machines properly. In this blog, I'm gonna walk you through the steps to ensure you shut down your screw type air compressor the right way.
Why Proper Shutdown Matters
Before we dive into the steps, let's talk about why it's so important to shut down your screw type air compressor properly. First off, a proper shutdown helps extend the lifespan of your compressor. When you shut it down correctly, you're reducing the wear and tear on the components. This means fewer breakdowns and less money spent on repairs in the long run.
Secondly, it's a safety thing. If you don't shut down the compressor properly, there could be pressure build - up or other issues that might lead to accidents. So, for the safety of your employees and the longevity of your equipment, it's crucial to follow the right shutdown procedure.
Step 1: Stop the Air Production
The first step in shutting down a screw type air compressor is to stop the air production. You do this by turning off the power to the compressor. But don't just flip the switch and walk away! Make sure that all the air - consuming equipment connected to the compressor is also turned off. This includes things like pneumatic tools, air - operated machinery, and any other devices that rely on compressed air.
By stopping the air production and disconnecting the air - consuming equipment, you're preventing any back - flow of air into the compressor. This can cause damage to the compressor's internal components, so it's an important step.
Step 2: Release the Pressure
Once you've stopped the air production, the next step is to release the pressure from the compressor. Most screw type air compressors have a built - in pressure release valve. You can usually find this valve near the air tank or on the compressor itself.
Open the pressure release valve slowly. This allows the compressed air to escape in a controlled manner. If you open the valve too quickly, it can cause a sudden drop in pressure, which might damage the compressor or create a safety hazard. Keep an eye on the pressure gauge as you release the pressure. You want to make sure that the pressure drops to zero before moving on to the next step.
Step 3: Drain the Condensate
Over time, moisture can build up in the air compressor's tank and other components. This moisture, known as condensate, can cause rust and corrosion, which can damage the compressor. So, it's important to drain the condensate regularly, especially when shutting down the compressor.
Locate the condensate drain valve on the air tank. This valve is usually at the bottom of the tank. Open the valve and let the condensate drain out. You might need to hold the valve open for a few minutes to make sure all the condensate is removed. Once the condensate has drained, close the valve tightly.
Step 4: Check the Oil Level
Screw type air compressors rely on oil to lubricate their moving parts. Before shutting down the compressor, it's a good idea to check the oil level. Most compressors have an oil sight glass or a dipstick that you can use to check the oil level.
If the oil level is low, add the appropriate type of oil to the compressor. Make sure you use the oil recommended by the manufacturer. Using the wrong type of oil can cause damage to the compressor. Also, check the oil for any signs of contamination, such as dirt or metal particles. If the oil is contaminated, it should be changed.
Step 5: Turn Off the Cooling System
Many screw type air compressors have a cooling system to prevent the compressor from overheating. This could be an Industrial Cooling Water Tower or a fan - based cooling system.
Once you've completed the previous steps, turn off the cooling system. This helps conserve energy and also prevents any potential issues with the cooling system while the compressor is not in use.
Step 6: Inspect the Compressor
Before you leave the compressor for an extended period, take a few minutes to inspect it. Look for any signs of leaks, loose connections, or damage. Check the belts, hoses, and other components for wear and tear.
If you notice any issues, make a note of them and address them as soon as possible. This can help prevent more serious problems from occurring in the future.


Additional Considerations
- Regular Maintenance: Shutting down the compressor properly is just one part of the equation. Regular maintenance, such as changing the filters, checking the valves, and servicing the Industrial Vane Pump and Speed Reducer, is also essential for the proper functioning of the compressor.
- Emergency Shutdown: In case of an emergency, you might need to shut down the compressor quickly. Most compressors have an emergency stop button that you can press to immediately cut off the power. However, this should only be used in cases of extreme danger, as it can cause damage to the compressor if done frequently.
- Training: Make sure that all the employees who operate the compressor are trained on the proper shutdown procedure. This can help prevent mistakes and ensure the safety of everyone in the workplace.
Shutting down a screw type air compressor properly is not that complicated, but it's very important. By following the steps I've outlined above, you can ensure that your compressor lasts longer, operates safely, and performs at its best.
