their are many reasons a compressor can fail (refrigeration)
1 low oil level due to low suction pressures or oil wash out due to liquid flooding back to the compressor 2 wrong supper heat setting on tx valve system3 wrong size compressor for the load 4 under or over voltage5bad starting or running cap or start relay and the list goes on....

HOW TO OPERAte a screw compressor and reciprocating compressors in series?
Your reciprocating compressors have to be the booster compressors (if running on low temp system)feeding its discharge to the suction of the screw(not directly)(if running on medium temp.
What are 2 types of dynamic compressors?
Reciprocating and screw?
What are application of rotary screw compressors?
Rotary screw compressors are used in many industrial compressed air systems due to the high volume they produce in comparison to reciprocating compressors. Rotary screws take up much less space, require no heavy flywheels, and need less maintenance than the recip. compressors. Oil free compressed air can be produced by large rotary screw compressors designed as such, while reciprocating compressors can do this only on a smaller scale due to the need for cylinder lubrication in the larger models.
How Does Heating From A Heat Pump Work?
The heart of the heat pump is the Copeland scroll compressor. The compressor continuously pumps the ozone safe refrigerant from the outside coils to the inside coils. The refrigerant carries the heat with it to be released inside the house. Then the warm air is circulated throughout the home by the furnace fan. In the summer the flow of the refrigerant reverses and the house is cooled in the same way. The scroll compressors are extremely reliable and virtually trouble free. Copeland is the largest manufacturer of heat pump compressors in the United States. Our Goodman heat pumps are built to last with reliable Copeland scroll compressors. Scroll compressors are very durable because they have fewer parts than the older reciprocating compressors and are also simpler in construction. Instead of pistons and valves which the older compressors had, the scroll compressor has a scroll that orbits to compress the refrigerant.
What is a non positive displacement compressor?
Well it is very important factor in fluid mechanics. The term comes often in compressors and Pumps. Displacement means change of place( Fluid ), Positive displacement means at all points of operating the discharge will be the same where as the discharge in non positive displacement varies at various operating points. For clear idea on the above compare the reciprocating pump with centrifugal pump at various operating points (by throttling) discharge valve).
Reciprocating compressors have?
Reciprocating compressors are positive displacement in machines. However, separable compressors have higher maintenance costs.
What is the advantage and disadvantage of reciprocating compressors?
The advantages of the reciprocating compressors is that it is easier to install and is very simple to install. The disadvantage of the reciprocating compressor is the high cost of maintaining it because of the many moving parts.

Your reciprocating compressors have to be the booster compressors (if running on low temp system)feeding its discharge to the suction of the screw(not directly)(if running on medium temp.
What are 2 types of dynamic compressors?
Reciprocating and screw?
What is the difference between screw chiller and reciprocating chillers?
screw is low maintenance than reciprocating reciprocating is more saving for power supply the compressors in screw is semehermatic but in reciprocating is open
What is compressor snubber?
Snubber is Pulsation damper that is installed on suction and discharge of compressors. It provides a continuous stream on reciprocating compressors.
Can reciprocating compressor surge?
Compressor surge only occur in centrifugal compressors. reciprocating compressor don't as they increase pressure by volume reduction, unlike centrifugal compressors where they increase pressure by converting kinetic energy to potential energy (pressure).
What are application of rotary screw compressors?
Rotary screw compressors are used in many industrial compressed air systems due to the high volume they produce in comparison to reciprocating compressors. Rotary screws take up much less space, require no heavy flywheels, and need less maintenance than the recip. compressors. Oil free compressed air can be produced by large rotary screw compressors designed as such, while reciprocating compressors can do this only on a smaller scale due to the need for cylinder lubrication in the larger models.
Which is better rotary or reciprocating air conditioners?
Reciprocating air compressors, are less popular in residential cooling systems because they are noisier than a Rotary unit plus the Rotary will cool better.....
What type of compressor is preferred with refrigerant R-113?
The Reciprocating compressors is the type of compressor that is preferred with refrigerant R-113.
Why are most compressors custom made?
The majority of compressors manufactured are custom made to a client's specific requirements for use in complex applications where the failure of the compressor could be disastrous.
What are Single acting reciprocating compressors?
A type of reciprocating/positive displacement compressor in which the gas is compressed using a piston cylinder that is connected to a crankshaft. As a result of the flywheel rotation, the crankshaft moves the piston causing it to compress the air. The most common application for such type of compressors are the internal combustion engines
