How to replace the spare parts of a screw air compressor?

by stefan•

Hey there! I’m working for a screw air compressor supplier, and I often get asked about how to replace the spare parts of a screw air compressor. Today, I’m gonna share some practical tips and steps to help you out with this task. Screw Air Compressor

First things first, why would you need to replace the spare parts of a screw air compressor? Well, over time, parts can wear out due to constant use, high – pressure operation, or just general aging. Replacing worn – out parts can improve the efficiency of the compressor, prevent breakdowns, and extend its lifespan.

Let’s start with some basic tools you’ll need. You’re gonna need a set of wrenches, both open – end and socket, a screwdriver set (both flat – head and Phillips), a torque wrench, and maybe a pair of pliers. Having these tools at hand will make the replacement process much smoother.

Step 1: Preparation

Before you start replacing any parts, make sure the compressor is turned off and unplugged. This is crucial for your safety. Also, release all the pressure in the compressor. You can do this by opening the drain valve. It usually takes a few minutes for all the pressure to escape. Once the pressure is off, we can start dealing with the specific parts.

Step 2: Air Filter Replacement

The air filter is one of the most important parts of a screw air compressor. It keeps dust and debris from entering the compressor, ensuring clean air intake. To replace the air filter:

  1. Locate the air filter housing. It’s usually a large, round or rectangular box near the compressor intake.
  2. Unscrew the housing cover using a screwdriver or a wrench, depending on the type of fasteners.
  3. Take out the old air filter. You might notice it’s dirty or clogged.
  4. Insert the new air filter. Make sure it fits snugly in the housing.
  5. Put the cover back on and tighten the fasteners.

Step 3: Oil Filter Replacement

The oil filter helps keep the compressor oil clean. Over time, it can get filled with contaminants, so it needs to be replaced regularly.

  1. Find the oil filter. It’s often located near the oil sump.
  2. Use an oil filter wrench to loosen the old oil filter. Turn it counter – clockwise.
  3. Once it’s loose, remove the old filter by hand. Be careful, as there might be some oil dripping.
  4. Before installing the new filter, apply a thin layer of clean oil to the rubber gasket on the new filter.
  5. Screw the new filter onto the filter housing by hand. Then, use the oil filter wrench to tighten it a bit more. Just make sure not to over – tighten it.

Step 4: Belt Replacement

If your compressor uses belts to transfer power, they might need to be replaced if they’re worn or loose.

  1. Find the belt guard. Usually, it’s a metal or plastic cover that protects the belts.
  2. Remove the belt guard using a screwdriver or a wrench.
  3. Loosen the tension on the belts. You can do this by adjusting the tensioner pulley.
  4. Slip the old belts off the pulleys.
  5. Install the new belts. Make sure they’re properly seated on the pulleys.
  6. Adjust the tension of the new belts. You can use the tensioner pulley again. You want the belts to be tight enough to transfer power but not too tight that they put excessive strain on the motor.
  7. Put the belt guard back on.

Step 5: Oil Separator Replacement

The oil separator separates the oil from the compressed air. When it gets clogged, the compressor efficiency can drop.

  1. Identify the oil separator. It’s usually a large, cylindrical component.
  2. Disconnect the inlet and outlet pipes from the separator. Use wrenches to loosen the fittings.
  3. Remove the separator from its mounting.
  4. Replace it with a new oil separator.
  5. Reconnect the inlet and outlet pipes. Make sure the connections are tight to prevent any air or oil leaks.

Step 6: Check and Reassemble

After replacing all the necessary parts, it’s important to double – check everything. Make sure all the parts are properly installed, all the fasteners are tightened, and there are no loose connections.

Then, you can plug in the compressor and turn it on. Listen for any unusual noises. If everything sounds normal, check the pressure gauge to make sure the compressor is building up pressure correctly.
