Look at the pressure, check for leaks Pressure gauge can be used to measure the cylinder pressure, find out the poor sealing cylinder.Reasons for poor cylinder sealing: valve clearance or clearance is too small, piston and cylinder sleeve and piston ring end face clearance is too large, ring groove carbon.In the diesel engine work, if close to the air filter can hear the "hiss, hiss" blowing sound...

Water temperature, check cooling If the cooling system temperature of the diesel engine is too high (more than 100℃) during operation, it can indicate that the scale in the cooling water cavity of the diesel engine is too thick or that relevant components of the cooling system (thermostat, water pump, fan, etc.) are inefficient or fail. Look at the distribution and check the phase After a long per...

Look at the carbon, check the working condition The carbon accumulation in the exhaust port of diesel engine is black gray, and the surface is covered with a layer of white frost. The carbon accumulation layer is very thin, which indicates that the diesel engine works well.The charcoal color is black and not wet, indicating that the diesel engine burns oil slightly.The thick carbon accumulation in...

Look up and down smoke, check wear and tear When the diesel engine is working, open the oil cap. If a stream of smoke comes out from the cap, weigh the smoke.Serious lower smoke phenomenon, indicating that the piston, cylinder liner, piston ring and other components are seriously worn.Open the valve chamber cover, if there is a trace of blue or white smoke from the valve root (valve face), weigh t...

A, timing, The factors that influence the frequency of grease replacement are very complex and generally include temperature, service continuity, amount of grease injected, bearing size and speed, sealing effectiveness, and suitability of the grease for particular applications.Therefore, deciding when and how often to replace the grease is not a simple matter. Under normal circumstances, continuou...

The lubrication of diesel generator set is a very important maintenance step, but many inferior lubricants in the market are mixed with too much water, affecting the actual use, how do we distinguish this inferior lubricants? First, heat the oil in a test tube to 110 to 120 degrees Celsius. If the oil makes a "crackle" sound, it indicates water.If there is water in the oil, use indirect heating me...

The diesel generator set should be operated by personnel who are familiar with the structure of the generator set and master the safe operation rules.New or recently overhauled diesel generator set need to undergo 50 hours of run-in and necessary maintenance. Before running new generators or generator which keep in stock for long term,you need do strict inspection for it, mainly to check the windi...

During the use of diesel generator sets, users may encounter some problems, including water leakage. 1. Adhesive bonding.If the water tank or water pipe is broken or the air hole causes small leakage, we can clean the leaking area and then apply adhesive. 2. Add padding.If there is a leak in the joint, we can add a thin layer of plastic cushion on both sides of the leak-proof ring and tighten it f...
