Due to the pressure rise developed through the impeller, a pressure difference exists across the hubs and covers such that the impellers have a net thrust in the direction of the compressor inlet. The balance piston counteracts that by being located behind the last impeller. This is accomplished by subjecting the outboard side of the balance piston to a low pressure from the inlet side of the compressor thereby creating a pressure differential opposite to the direction of the impellers. This pressure is acheived by connecting the area behind the piston to the inlet using a line. The impeller thrust not balanced by the balace piston is absorbed by the thrust bearings.

I hope this helps

Which compressor is mostly used for the supercharging of IC engines?

Centrifugal compressor


What is the use of a turbine in refrigeration?

It is used as a compressor. It has the same advantages over a piston compressor as a gas turbine engine has over a piston engine. i.e. no valves, much lower part count and much greater efficiency.


What is diaphragm used for a centrifugal compressor?

diaphrams are static ones containing guide blades...steam from suction end enters the suction diaphragm and get guided to impeller of centrifugal compressor..ntermediate diaphrams contains diffusers which changes pressure energy..these daphragms forms a part of inner casing.


Why flywheel is used in reciprocating compressor not in centrifugal compressor?

Flywheel prevents fluctuation in the speed of the motor as a result of load fluctuation. It stores the energy and dissipates it to the compressor for prolonged period. So the load fluctuation which is high during compression stage and low during other stages during a cycle in reciprocating compressor gets nullified. On the other hand, centrifugal compressor continiously compresses the gas and does not have load fluctuations, hence flywheel is not required.


What is the difference between centrifugal compressor and screw compressors?

A rotary compressor is like a car engine, with pistons, rods, sleeves, valves, etc. A screw compressor has two screw type rotating parts that squeeze the refrigerant as the screw threads get tighter and tighter. They have long life potential.

What is the balance drum used for a centrifugal compressor?

In a centrifugal compressor, the energy is transferred using a set of impeller blades and balancing drums. These balancing drums can be on the inlet or outlet side of the compressor and help to space out the energy in the compressor.

What is the air compressor in a car used for?

The air conditioning compressor pressurizes the refrigerant sending it through a series of chambers. This compressor is normally called a centrifugal compressor.


The frontal area of a centrifugal compressor as compared to axial flow compressor is larger or smaller?

the frontal area of a centrifugal compresor is more as compared to axial flow compressor for a given air flow. And for this reason axial compressors are being used in aircraft engines.


What is difference betweenrotar of centrifugal pump and compressor?

pump is used to handle liquid and compressor is used to handle gases. other difference include blade shape etc..


What is rasiprocating compressor?

A reciprocating compressor is one in which a piston or diaphragm moves in a reciprocating motion. The compressor used in the AC system of a Saturn is NOT a reciprocating compressor. It is most likely a "rotary vane" compressor.
