Common Problems

Air Leaks

You might spot air leaks around fittings, hoses, or connections. If you hear a hissing sound or notice a drop in pressure, that’s a sign. Leaks can happen when seals wear out or pipes loosen. Sometimes, a faulty intake system causes normal operation but no pressure. Regular checks help you catch leaks early.

Overheating

Your Sollant Rotary Screw Air Compressor can trigger an overheating alarm if the temperature goes above 100°C. You may see the compressor stop or shut down. Overheating often comes from blocked filters, low oil levels, or poor ventilation. High exhaust temperature can also trip the system and cause shutdowns. Keeping the cooling system clean helps prevent this.

Tip: Always check the discharge temperature display. If it’s too high, let the compressor cool down before restarting.

Low Pressure

Low pressure can slow down your work. You might notice tools running weak or the compressor not reaching set pressure. This can happen if the compression valve gets stuck or if there are leaks in the pipes. Sometimes, a damaged time relay causes the pressure to drop while the motor keeps running. Inspecting valves and connections helps restore normal pressure.

Excessive Oil

If you see oil in the compressed air or around the machine, it’s a sign of excessive oil. This can come from worn seals or overfilled oil tanks. The Sollant Rotary Screw Air Compressor uses advanced oil filters to keep oil levels steady, but regular checks are still important. Clean filters and proper oil levels keep your air clean.

Noise and Vibration

Unusual noise or vibration can mean loose parts or worn bearings. You might hear rattling or feel shaking during operation. These issues can affect performance and safety. Tightening bolts and replacing worn parts helps keep your compressor running smoothly.

Starting Issues

Sometimes, your compressor won’t start. You may notice the pressure jumps to the upper limit right away, which can mean a stuck compression valve. Electrical problems or a faulty relay can also cause starting trouble. Checking the control panel and relays helps you find the problem fast.

Note: Sollant Rotary Screw Air Compressor models like the 11kw and 15kw have user-friendly displays to help you spot issues quickly.

Diagnosing Issues

Visual Checks

Start with a simple walk-around. Look at your compressor for anything unusual. You might see oil spots, loose wires, or dust buildup. Check the hoses and fittings for cracks or leaks. If you spot a puddle or hear a hiss, you probably have a leak. Make sure the control panel lights up and shows normal readings. If you see warning lights, take note. Sometimes, just looking closely helps you catch problems before they get worse.

Performance Monitoring

Keep an eye on how your compressor runs. Watch the pressure gauge and listen for changes in sound. If the machine starts making strange noises or the pressure drops, something might be wrong. You can use special tools to track vibration and temperature. These tools help you spot trouble early.

Vibration analysis is the testing and tracking of an air compressor’s vibration profile to aid in diagnosing any current or future faults. Every compressor has its own vibration signature and documenting and tracking that unique vibration allows you to ‘see’ a number of performance issues.

Here are some ways technology helps you monitor performance:

IIoT technology collects, transmits, and analyzes key performance indicators (KPIs) from compressors.
You get 24/7 real-time data monitoring.
Service teams and plant managers can check machine health and receive alerts from anywhere.

Using Diagnostic Tools

You have lots of tools to help you find problems. Use a thermal camera to check for hot spots. Try a vibration meter to measure shaking. Plug in a pressure tester to see if the air output matches the settings. Some models of the Sollant Rotary Screw Air Compressor come with smart displays that show error codes and system status. These features make it easier for you to spot issues fast. If you’re not sure what a reading means, ask your service team for help. They can use advanced tools to dig deeper and fix problems before they slow you down.

Solutions for Sollant Rotary Screw Air Compressor

Fixing Air Leaks

Air leaks can waste energy and lower your compressor’s performance. You can fix most leaks with a few simple steps:

Listen for hissing sounds, especially when the workshop is quiet. This helps you find leaks fast.
Use an ultrasonic acoustic detector. This tool picks up high-frequency sounds from leaks, even in noisy places.
Tighten all connections and fittings. Sometimes, a loose part is the only problem.
Replace old or worn hoses and seals. Fresh parts stop leaks before they start.
Apply thread sealant the right way. A good sealant keeps air from escaping.

If you use a Sollant Rotary Screw Air Compressor like the 11kw or 15kw model, regular checks make a big difference. These compressors have easy-access panels, so you can inspect fittings and hoses quickly. Try to check for leaks every week. This habit saves energy and keeps your compressor running strong.

Resolving Overheating

Overheating can cause your compressor to shut down or slow your work. You can prevent this by keeping the cooling system clean and making sure the oil level stays right. Here’s what you can do:

Clean the air filters and cooling fins often. Dust and dirt block airflow and raise the temperature.
Check the oil level before each use. Low oil makes the compressor work harder and get hotter.
Make sure the compressor has enough space around it. Good airflow helps cool the machine.
Inspect the ventilation fans. Replace any that don’t spin well.

Sollant Rotary Screw Air Compressor models like the 22kw and 37kw have advanced temperature sensors. These sensors alert you if the temperature gets too high. If you see a warning, let the compressor cool down before restarting. Regular cleaning and oil checks help you avoid most overheating problems.

Tip: Set a reminder to clean filters and check oil every week. This simple step can prevent most overheating issues.

Restoring Pressure

Low pressure can slow down your tools and make jobs take longer. You can restore pressure by checking a few key parts:

Inspect the compression valve. If it sticks, clean or replace it.
Look for leaks in the pipes and hoses. Even a small leak can drop the pressure.
Check the time relay. If it’s damaged, swap it out for a new one.
Make sure the intake filter is clean. A clogged filter limits airflow.

Sollant compressors like the 45kw and 7.5kw models have adjustable pressure settings. Use the control panel to set the right pressure for your job. If you notice pressure dropping, check these parts first. Quick fixes keep your work moving.

Reducing Oil Consumption

Too much oil in your compressed air can cause problems for your tools and products. You can reduce oil consumption with these steps:

Inspect and overhaul the minimum pressure valve. This stops oil and gas from leaking, which keeps oil use low.
Replace oil filters on schedule. Sollant compressors use high-density filter materials that separate oil from air better.
Use the right oil type and fill to the correct level. Too much or too little oil can cause waste.
Check for worn seals and gaskets. Replace them if you see oil around the machine.

The Sollant 7.5kw industrial air compressor uses less oil than many other models. If you want even better oil control, look for compressors with advanced oil separation systems, like the 55kw screw drive air compressor. Regular filter changes and valve checks help you save oil and money.

Quiet Operation

Loud compressors can make your workspace uncomfortable. Sollant Rotary Screw Air Compressor models are designed to run quietly, but you can keep them even quieter with a few steps:

Tighten all bolts and fasteners. Loose parts can rattle and make noise.
Replace worn bearings and rubber mounts. These parts absorb vibration and lower sound.
Place the compressor on a flat, stable surface. Uneven floors can cause extra vibration.
Use sound-dampening mats if your workshop is very quiet.

The 37kw and 45kw models have direct drive systems and soft start inverters. These features help reduce noise and vibration. If you notice new sounds, check for loose or worn parts right away.

Note: A quiet compressor is a sign of good health. Listen for changes in sound to catch problems early.

Starting Troubleshooting

If your compressor won’t start, don’t worry. You can solve most starting problems with a few checks:

Look at the control panel for error codes or warning lights.
Make sure the power supply is steady and the emergency stop button is not pressed.
Check the pressure switch. If it’s stuck at the upper limit, reset or replace it.
Inspect relays and fuses. Swap out any that look burned or broken.
