What are the remedies in cases of turbocharger surging?

How to Prevent Turbocharger Surging?

• Keep the turbocharger intake filter clean.
• Water-wash the turbine and the compressor side of the turbocharger.
• Proper maintenance and checks should be done for different turbocharger parts periodically.
• Soot blow should be done from time to time in case of economizer or exhaust boiler.

How can compressor stall be avoided?

Variable-pitch stators (to control flow angles), compressor bleeds, casing treatments, and tip clearance controls all are used to avoid stall conditions.

What causes compressor surge?

Surge occurs when there is no forward flow of gas through the compressor and a reversal of flow occurs. The gas that is being compressed gets pushed backward through the centrifugal compressor. When this surge (flow reversal) occurs, which can happen in milliseconds, the rotor is affected.

When air from the compressor wheel enters the diffuser and then the volute what happens to it?

As air proceeds through the compressor wheel it makes a 90° turn thus changing its flow from an axial to a radial direction. Air exits the compressor wheel at the exducer (2), enters a narrow stationary diffuser and then passes through to a volute or scroll from which it is discharged from the compressor.

Can bad spark plugs cause engine surging?

3. Surging and Lagging. Another good indication that your spark plugs are dirty or worn is if your vehicle experiences surges of speed, resulting in a jerking acceleration. These surges occur because your spark plugs are not igniting the fuel in your engine at the proper rate, resulting in an uneven speed.

How do you stop a turbo from failing?

4 tips to prevent turbo problems

1. Regular maintenance. It is important that the vehicle is serviced on time and on a regular basis.
2. Timely oil changes. The engine oil must be changed correctly and on time.
3. Use of correct and good quality engine oil. The engine oil must of course meet the prescribed quality.
4. Gentle startup.

What happens when compressor blades stall?

A compressor stall will result in a loss of thrust and is likely to produce a “backfire” like sound due to reverse airflow. It may also be accompanied by flame from either or both of the engine inlet and engine exhaust. A sustained compressor stall can result in engine damage and can lead to engine failure.

What is stall margin?

The stall margin (SM) is the percentage of lift coefficient. remaining for use by the pilot at any given time in the. airplane’s flight operation.

What happens during compressor surge?

Surging can cause the compressor to overheat to the point at which the maximum allowable temperature of the unit is exceeded. Also, surging can cause damage to the thrust bearing due to the rotor shifting back and forth from the active to the inactive side. This is defined as the surge cycle of the compressor.

How do you test if your turbo is working?

There are a number of signs you can look out for to tell if your turbocharger has blown:

1. POWER LOSS.
2. WHINING ENGINE.
3. EXHAUST SMOKE.
4. CHECK ENGINE LIGHT.
5. OIL/LUBRICATION.
6. DAMAGED SEALS.
7. FOREIGN OBJECTS/DEPOSITS.
8. WEAR & TEAR.

What is the main function of turbocharger?

The objective of a turbocharger is to improve an engine’s volumetric efficiency by increasing the pressure of the intake gas (usually air) allowing more power per engine cycle. The turbocharger’s compressor draws in ambient air and compresses it before it enters into the intake manifold at increased pressure.

When to take corrective action on compressor vibration?

You should monitor compressor vibration and take appropriate corrective action when vibration levels are high. However, if you suspect entrainment, remember that low vibration levels are a poor indicator that entrainment isn’t causing damage.

Can a reciprocating compressor draw normal current levels?

A reciprocating compressor can draw normal current levels while in operation or there could be infrequencies as a result of certain inability on the system. Nonetheless, a low compressor amp draw will give the idea that there may be performance issues with your valve. 3. Check Compressor Shell for Overheating

What should you do if your compressor fails?

In multiple incidents, liquid entrainment has resulted in compressor operation with very low vibration levels; the compressor operated successfully for an extended period but then catastrophically failed. You should monitor compressor vibration and take appropriate corrective action when vibration levels are high.

What causes low discharge from a reciprocating compressor?

However, a weak and inefficient discharge from a reciprocating compressor could be a sign of valve failure. When the pressure appears inadequate, the valve passage may have been blocked. In some cases, low discharge pressure is usually accompanied by excessive suction pressure.
