Hey there! As a supplier of diesel screw compressors, I often get asked about the best way to store these machines when they're not in use. Proper storage is crucial to ensure the longevity and optimal performance of your diesel screw compressor. In this blog, I'll share some practical tips on how to store your compressor effectively.

Why Proper Storage Matters

First off, let's talk about why proper storage is so important. Diesel screw compressors are complex pieces of equipment with various components that can be affected by environmental factors and inactivity. If not stored correctly, you might end up with issues like corrosion, oil degradation, and mechanical wear. These problems can lead to costly repairs and downtime when you need to use the compressor again.

Pre - Storage Preparations

Before you store your diesel screw compressor, there are a few key steps you need to take.

Clean the Compressor

Start by giving the compressor a thorough cleaning. Remove any dirt, debris, or oil stains from the exterior. You can use a mild detergent and a soft cloth to clean the surfaces. Make sure to clean the air intake filters as well. Dirty filters can restrict airflow and cause the compressor to work harder, leading to premature wear.

Drain the Fluids

Next, drain all the fluids from the compressor. This includes the oil, coolant, and compressed air. Draining the oil is especially important because over time, oil can break down and form sludge, which can damage the internal components. Follow the manufacturer's instructions on how to drain the fluids properly.

Check for Leaks

Inspect the compressor for any signs of leaks. Look for oil, coolant, or air leaks around the fittings, hoses, and gaskets. If you find any leaks, repair them before storing the compressor. Leaks can lead to fluid loss and potential damage to the compressor.

Lubricate Moving Parts

Apply a light coat of lubricant to all the moving parts, such as the pistons, bearings, and gears. This will help prevent rust and corrosion during storage. Make sure to use the lubricant recommended by the manufacturer.

Choosing the Right Storage Location

The location where you store your diesel screw compressor is just as important as the pre - storage preparations.

Indoor Storage

If possible, store the compressor indoors. An indoor storage area protects the compressor from the elements, such as rain, snow, and extreme temperatures. A dry, well - ventilated warehouse or shed is an ideal location. Make sure the storage area is clean and free from dust and debris.

Temperature and Humidity

Keep the storage area at a stable temperature and humidity level. Extreme temperatures can cause the fluids in the compressor to expand or contract, which can lead to leaks and damage. High humidity can cause corrosion, so it's important to keep the humidity below 60%. You can use a dehumidifier if necessary.

Elevated Surface

Place the compressor on an elevated surface to prevent it from sitting in water or moisture. A wooden pallet or a metal stand works well. This will also help with ventilation around the compressor.

Protecting the Compressor During Storage

Once you've prepared the compressor and chosen the right storage location, it's time to take some additional steps to protect it.

Cover the Compressor

Use a high - quality cover to protect the compressor from dust, dirt, and moisture. Make sure the cover fits snugly and is made of a breathable material. A non - breathable cover can trap moisture, which can lead to corrosion.

Disconnect the Battery

If your diesel screw compressor has a battery, disconnect it before storage. This will prevent the battery from discharging and potentially causing damage to the electrical system. Store the battery in a cool, dry place and charge it periodically.

Secure Loose Parts

Make sure all the loose parts, such as hoses, belts, and tools, are securely stored. You can use zip ties or storage containers to keep them organized. This will prevent them from getting lost or damaged during storage.

Periodic Inspections

Even if your compressor is in storage, it's important to perform periodic inspections.

Monthly Checks

Check the compressor at least once a month. Look for any signs of corrosion, leaks, or damage. Inspect the cover to make sure it's still in good condition. If you notice any issues, address them immediately.

Fluid Checks

If you've drained the fluids, you don't need to check them during storage. However, if you've left some fluids in the compressor, check the levels periodically. Make sure the fluids are still in good condition and there are no signs of contamination.

Reactivating the Compressor

When you're ready to use the compressor again, there are a few steps you need to take to reactivate it.

Refill the Fluids

Refill the oil, coolant, and compressed air according to the manufacturer's specifications. Make sure to use the correct type and grade of fluids.

Reconnect the Battery

Reconnect the battery and charge it if necessary. Check the electrical connections to make sure they're secure.

Inspect the Filters

Inspect the air intake filters and replace them if they're dirty or damaged. Clean filters are essential for proper airflow and efficient operation of the compressor.

Run a Test

Before putting the compressor to full - time use, run a test. Start the compressor and let it run for a few minutes. Listen for any unusual noises or vibrations. Check the pressure gauges to make sure the compressor is operating at the correct pressure.
