What causes the abnormal water temperature of Weichai diesel engine?
Abnormal water temperature Since the abnormal water temperature is manifested as too high outlet temperature or too large temperature difference between inlet and outlet, both aspects should be considered when analyzing the reasons. The diesel engine is overloaded or the oil supply angle is too e...Read more -
The principle of diesel generator set mechanical governor?
The mechanical governor automatically adjusts the speed of the diesel engine according to the centrifugal force generated by the diesel engine, and the speed of the diesel engine is only allowed to be adjusted within the set speed range. The mechanical speed control system works by the flyweight ...Read more -
The reason why the diesel engine cannot crank the engine or the cranking speed is too low and how to deal with it?
The reasons why the diesel engine cannot crank the engine or the cranking speed is too low and the solutions 1. The battery is not sufficiently charged. Treatment method: Check the electronic voltage of the battery, if it is insufficient, charge the battery and replace it if necessary. 2. The mai...Read more -
The reason why the engine does not reach the rated speed and how to deal with it?
Reasons and solutions for the engine not reaching the rated speed A use the wrong type of lubricant Treatment method: replace lubricating oil and filter B cooling start system failure Treatment method: Check, repair the cooling start device, and replace if necessary C start temperature is too low...Read more -
What should I do if the diesel engine is stopped due to overspeed failure?
What should I do if the diesel engine is stopped due to overspeed failure? 1. Check whether the indication of the tachometer is abnormal 2. For the mechanical speed control system, check whether the throttle lever is flexible and ensure correct adjustment 3. For the electronic speed control syste...Read more -
The choice of emergency diesel generator set?
In an emergency, the unit is more suitable for high-speed, pressurized, low fuel consumption and the same capacity generator set. In addition to the selection of the diesel generator set in the stationary state, the generator set should also be selected in the emergency state, and the selection o...Read more -
What are the conditions for the difficulty of starting a diesel generator set?
1. Circuit failure. Wrong wiring connection; poor contact; insufficient battery capacity. 2. The oil circuit is an oil circuit, the oil circuit is blocked, the diesel filter is blocked, the fuel transfer pump does not supply oil, the injection hole of the injector is blocked by carbon deposits, t...Read more -
What should be paid attention to when the generator set runs with high power for a long time?
Matters needing attention when the generator set runs at high power for a long time. When the generator set is used as a public power source for a long time, how to minimize the damage of the generator set when it runs for a long time. The air filter is a trivial but important part of the entire ...Read more -
Should antifreeze be added to the water tank of the diesel generator set?
The full name of antifreeze coolant is antifreeze coolant. It is a special purpose antifreeze coolant that prevents the radiator and engine from expanding due to freezing in severe winter. Antifreeze is not only suitable for use in winter, but also suitable for use throughout the year. There are ...Read more -
What should be paid attention to in the normal shutdown and emergency shutdown of diesel generators?
How should the shutdown operation of the diesel generator set be carried out? Cut off the power directly? The basic process of three operations of diesel generator set operation, normal shutdown and emergency shutdown. 1. Operation After the unit runs at full speed, the generator voltage and freq...Read more -
Under what circumstances does an emergency shutdown of the diesel generator set need to be implemented?
The shutdown of diesel generator sets is generally carried out according to strict steps when the power supply work is completed. However, in actual use, users may encounter some emergencies that require emergency shutdown. What situations require emergency shutdown of the unit? 1. The oil pressu...Read more -
Why does the oil consumption of diesel generator sets increase?
After the diesel generator set is used, the oil consumption slowly rises. The following reasons and solutions are summarized: 1. The oil return pipeline of the supercharger is not smooth (remove dirt) 2. The turbine end sealing ring is damaged (send to the supercharger repair station for repair) ...Read more
