The main characteristics of the piston knocking cylinder in the power part of the generator set are abnormal sound

The common abnormal sound of the crank connecting rod mechanism in the power part of the generator set is the piston knocking cylinder ring, piston ring, piston pin ring, connecting rod bearing ring, crankshaft bearing ring and cylinder ring. Today we will introduce the characteristics of the piston knocking cylinder in the power part of the generator set.

Usually the piston knock cylinder abnormal sound occurs in the upper part of the power cylinder of the generator set, generally at the beginning of the piston power stroke, the piston swings or moves in the cylinder, its head or skirt and cylinder wall, cylinder head collision, the sound has the following characteristics: When the power part of the generator set is running at idle speed, the sound is similar to a small hammer knocking, which is a rhythmic "Da da da" sound, obvious and clear.

The knocking sound changes with the change of the temperature of the power part of the generator set, and the sound is more obvious at low temperature. When the temperature rises, its sound weakens or disappears. When the speed is suddenly increased, a continuous metallic tapping sound is made. If the multi-cylinder piston hits the cylinder, when the speed rises, the noise is noisy and disordered.

The above is Shenzhou Wanda for you to introduce the main characteristics of the power part of the generator generating piston cylinder abnormal sound, what do you not know about this, welcome to consult our Shenzhou Wanda website, we will have professional people to explain for you.
