Turbocharger Use Taboos and Life Extension Tips

Turbocharger is an important engine parts in diesel engine, which has become the core component to improve power and reduce fuel consumption. However, turbocharger is extremely sensitive to the use of environment and maintenance. According to statistics, more than 60% of turbocharger failures are directly related to improper human operation. This article will introduce you to the use of turbocharger taboos, and reveal the key tips to extend its service life.

1.Taboo

① Violent driving in cold car

In the cold car state, the oil viscosity is high, the mobility is not enough, if you step on the gas pedal deeply at this time, it will lead to the bearing instantly in a semi-dry friction state. Experimental data show that the wear in the first minute after cold start accounts for 45% of the total wear. Build until the oil pressure gauge pointer stabilized before starting.

②Select poor quality engine oil

Turbocharger working temperature is very high, ordinary mineral oil at high temperatures is easy to oxidize and coking, the formation of sludge blocking the oil channel. Must use the standard oil.

③Long idling

Idle engine speed is low, the oil pump oil supply is reduced, while the turbocharger blades in the exhaust gas to promote still maintain high-speed rotation. This condition will lead to insufficient lubrication of the bearings and higher back pressure of the impeller. It is recommended that the single idling time should not exceed 10 minutes, and if you need to stop for a long time, you should turn off the engine and wait.

2. Life extension tips

①Establish pre-lubrication mechanism

In cold areas or after a long period of parking, you can use the “two-stage start method”: the first start after idling for 1 minute to turn off the engine, after an interval of 30 seconds to start again. This method can make the oil fully saturated bearings, reduce cold start wear. A construction machinery enterprises through this method, so that the equipment turbocharger failure rate decreased by 73%.

② implementation of accurate maintenance

Maintenance cycle needs to be dynamically adjusted according to the working conditions:

Conventional road transport: every 50,000 kilometers to change the oil and filter

Heavy-duty working conditions/dusty environment: deep cleaning every 20,000 kilometers

Abnormal oil consumption: Check turbocharger sealing rings immediately.

Special attention should be paid to changing the bypass valve filter element at the same time as the oil change to avoid metal shavings from entering the lubrication system.

③Adopt intelligent monitoring

Equipped with special monitoring module for turbocharger, the following parameters are collected in real time:

Bearing temperature

Rotor axial clearance

Boost pressure fluctuation value

When the monitored bearing temperature exceeds 125℃, the system automatically restricts the engine torque output, forming a protection mechanism.

The service life of turbocharger not only depends on the manufacturing process, but also on the user's maintenance awareness. engine parts sold by Keluo Construction Machinery are creating sustained value for global users with excellent performance and reliable quality.
