Qgb Cylinder Fault Inventory and Its Solution
Aug 15, 2019
Wear analysis of QGB cylinder:
1. There are signs of pull on the surface of the cylinder, which indicates that the engine works at high temperature or for a long time under overload.
2. Cylinder wear is too large, engine use time is too long, maintenance is not in place, lubrication is not good, oil does not meet the requirements of use;
3. Cylinder roundness error is too large, which indicates that the engine works long time and heavy load, resulting in excessive force on the piston, or the engine often detonates and burns.
4. Cylinder wear is large in the middle and small at both ends, which is usually caused by abrasive wear. Engine air filter damage or poor filtration, too much dust in the working environment, etc., will cause this situation.
QGB cylinder block and end cover buffer leakage, check the following two points:
1. Seal rings at end caps are damaged. Seal rings should be replaced in time.
2. Inspect whether the fixing screw is loose or not and tighten it immediately.
The impact phenomenon exists at QGB cylinder stroke terminal:
1. Qgb cylinder itself has no cushioning measures, it is necessary to add appropriate cushioning measures in time.
2. Qgb cylinder cushion sealing ring has poor sealing performance, so it is necessary to replace the sealing ring in time.
3. Buffer throttle valve should be adjusted or replaced in time if it is loose or damaged.
4. Qgb cylinder has insufficient cushioning capacity, so the cushioning mechanism should be purchased again.
