An increase in speed could be caused by a heavily contaminated nozzle ring (with 4-stroke application). In this case, contact an ABB Turbocharging Service Station.
How to fix vibrations in ABB HT842921?
If you are experiencing vibrations, it could be due to rotor unbalance. In this case, contact an ABB Turbocharging Service Station.
Why is there fouling of the compressor due to the feeding in of ventilation gases in ABB HT842921?
Fouling of the compressor due to the feeding in of ventilation gases can occur due to heavy fouling of the compressor components, so clean compressor. It can also lead to increased vibrations or compressor blade damage, so correct the feed of ventilation gases according to instructions of enginebuilder. The material of the compressor wheel might be corroded, so check the fuel and its corrosive components, and change fuel if necessary.
Why is the exhaust gas temperature too high in my ABB charger?
If the exhaust gas temperature is too high in your ABB charger, it could be due to several reasons: * A malfunctioning injection system: Repair it or contact the manufacturer. * Air starvation (e.g., a filter silencer clogged with dirt): Clean the filter silencer. * High exhaust counterpressure: Clean or repair the boiler or exhaust silencer. * A contaminated cooler: Clean the cooler. * Low cooling water volume: Top up the water. * High cooling water entry temperature: Inspect or clean the cooling system. * Inadequate ventilation: Improve the ventilation.
What to do if ABB HT842921 has turbocharger surging?
If the turbocharger is surging, the guard in front of it may be contaminated or damaged, requiring cleaning or replacement. Another potential cause is a contaminated filter silencer or diffuser, which needs cleaning. Additionally, a contaminated cooler could be the source of the problem, so clean it. A blocked charge air duct also can cause turbocharger surging.
What to do if ABB HT842921 has charge air pressure too low?
If the charge air pressure is too low, there could be several reasons. The air receiver or the gas piping between the engine and the turbine might be leaking. A poorly adjusted injection system also can cause this issue, so correct it. The manometer display might be providing a wrong reading, so replace the manometer, or the line to the manometer might be leaking, so repair the leak. A contaminated filter silencer causing excessive loss of pressure can also be the reason, so clean it. In some cases, the compressor/turbine might be damaged, which requires contacting an ABB Turbocharging Service Station. High exhaust counterpressure can also cause low charge air pressure, so clean or repair the boiler or exhaust silencer.
Why is there a reduction in speed in ABB HT842921 Industrial Equipment?
A reduction in speed could stem from defects in connected cylinders during pulse charging, in which case you should contact the enginebuilder. Other potential causes include heavy contamination of the turbine (clean it), damaged rotor components or bearing (contact an ABB Turbocharging Service Station), or defects like leaks in the exhaust gas pipes or charge air ducts (make repairs).
What to do if lubricating oil pressure is too low in ABB HT842921 Industrial Equipment?
If the lubricating oil pressure is too low, the oil filter may be heavily contaminated and needs cleaning. Alternatively, the oil pump in the lubricating system could be defective and requires checking or replacement. A wrong reading on the manometer display can also cause this issue, so replace the manometer. In some instances, the rotor axial clearance may be too large, which requires contacting an ABB Turbocharging Service Station.
What to do if the exhaust gas temperature is too high in ABB Industrial Equipment?
If the exhaust gas temperature is too high, several factors could be responsible. The injection system may be malfunctioning, requiring repair or manufacturer contact. Air starvation might be occurring due to a filter silencer clogged with dirt, which needs cleaning. High exhaust counterpressure could be the issue, necessitating cleaning or repair of the boiler or exhaust silencer. Other potential causes include a damaged or eroded turbine (in which case you should contact an ABB Turbocharging Service Station), a contaminated cooler (clean it), low cooling water volume (top up the water), high cooling water entry temperature (inspect/clean the cooling system), or inadequate ventilation (improve the ventilation).
How to fix sluggish start-up in ABB HT842921 Industrial Equipment?
A sluggish start-up of your ABB Industrial Equipment could be caused by a contaminated turbocharger, which you can resolve by cleaning it. It may also be due to a damaged bearing, in which case you should contact an ABB Turbocharging Service Station. Other potential causes are rubbing rotor or a foreign object in the turbocharger.
