How to disassemble a diesel screw compressor

How to disassemble a compressor?

If it is possible, completely empty the compressor of the pumped liquid. Disassembly is carried out by following the indications given on tab. 1 and 2, which show, on the line of the compressor concerned, the sequence and the numeric amount of the details to be disassembled. In order to extract the bearing housings, use an adequate puller.

How does a rotary screw air compressor work?

Rotary screw air compressors operate by trapping air between two meshed rotors and reducing the volume of that trapped air as it moves down through the rotors. This reduction in volume results in compressed air, which can then be used to power air tools, inflate tires, and more.

How does an oil injected air compressor work?

Many components comprise an air compressor, but the system's heart is the air end, where air is compressed. An oil-injected air end looks like this: Air enters the air end through an inlet valve, where it is mixed with oil while being compressed. The oil is later separated from the compressed air, before it exits the system.

How does a screw compressor work?

A screw compressor can run loaded ('pumping air') or unloaded ('idle'). The inlet/loading valve opens and closes according to air demand. The inlet valve is controlled by a solenoid valve that supplies control air to the inlet/loading valve. Check solenoid valve coil and solenoid valve operation.

Why do rotary screw air compressors need oil?

Oil is a critical component of an oil-injected rotary screw air compressor, performing many important jobs at once. Oil lubricates the system, protects components from wear, keeps the system cool, and helps trap and remove contaminants.

What should I do if my air compressor is too low?

If the capacity of the air compressor is really too low, check the following: Check differential pressure over oil separator. Replace separator when necessary. Check and replace compressed air filters (if installed). Compressor does not unload. Check if pressure switch is correctly set and working.
