How Do Rotary Screw Air Compressors Operate?

The most usual sort of compressors made use of in commercial setups is the rotary screw air compressors. There are numerous strange suggestions bordering these rotary screw compressors. Most of those ideas pertain to cold weather and winterization. Straightforward maintenance can solve a number of the troubles and failures that support winter month’s weather condition. Many individuals believe that since their compressor is inside a heated structure, it will not be affected by outside air temperatures. This is not true, since the oil coolers are usually aired vent to the beyond the structure. Oil that is trapped in a cooler that is exposed to cool air can become thick and will certainly not flow. Some rotary screw air compressors have thermal or bypass shutoffs in the oil air conditioning system. This assists protect the compressor components during startup in winter.

The shutoff should be inspected frequently to ensure that it is operating appropriately. Artificial oil can be a great help since it will certainly flow much easier at reduced temperatures. However, the genuine problem is water build up in the oil sump because the water will certainly not boil off and vaporize when the compressor is functioning under 140 levels F. Problems triggered by the water build-up can be avoided by occasionally draining a percentage of oil during cold weather before beginning the compressor up.

Rotary Screw

 

Cold weather sometimes creates condensation to build-up airborne lines of the rotary screw air compressors. This can create sensing units to send the wrong signals to the screw compressors computer system control systems. This will certainly create the compressor to keep up complete lots until somebody notices the constant lifting of the stress relief valves. Condensation is removed through drains that are put tactically in the air system.

These Rotary Screw discharge lines are normally required to a drain point outside of the structure. Throughout winter, these lines can become obstructed with ice, compelling condensation back into the air system. Otherwise correctly drained before the compressor is closed down, this can harm a few of the compressor parts and expensive components.

It is common for services to take their rotary screw air compressors inactive throughout the winter season. This is good only if the appropriate steps are required to winterize the screw compressors. This consists of oil and filter changes.

Used oil creates an acid that can damage the bearings in the electric motor and the compressor components. By hand turning the electric motors and maintaining the blades oiled are additionally crucial to avoid taking at startup. Proper maintenance of the screw compressors is essential to avoid expensive service phone calls and to minimize downtime.
