Notice! The damage caused by the wrong operation of the diesel generator set will not be able to enjoy free after-sales service!

June 14, 2022
Diesel generator set is a commonly used power generation equipment in modern society. Generally, when purchasing a diesel generator set, the manufacturer will provide corresponding after-sales service, but please note: even if the generator is still within the warranty period, most generator after-sales service centers Failures caused by improper operation will also not be repaired free of charge. Therefore, before using the diesel generator set, the user must read the instruction manual carefully and pass the qualified operation training before operating the generator set. In order to avoid some wrong operation behavior, the user must pay attention to the following items!
1. Correctly select the unit capacity
Before purchasing a diesel generator set, the user must seriously consider the total power of the generator set. In fact, the most common cause of failures is an incorrect choice of technology, for example, the total power of the connected appliances does not meet the permissible values. Sure, high-quality power plant engines can handle peak loads, but only if they're short-term, not permanent. Therefore, before purchasing a unit, please accurately calculate the number of users and their total electricity consumption. Only in this way can the hidden dangers of overloading and premature wear of the main working parts be excluded.
2. Pay attention to fire safety
Diesel generator sets should be arranged in a well-ventilated place or artificially exhausted. There shall be no other inflammable and explosive materials at least 1 meter near the generator, and smoking and incitement near the operating unit are strictly prohibited.
3. Perform correct debugging
Before connecting the load to the diesel generator set, a trial run must be carried out. If the engine is prone to knots and no external noise can be heard, then the electrical appliances can be connected and run normally. When using high-sensitivity computer equipment or power supply units for alarm systems, it is advisable to additionally connect a voltage stabilizer.
But as we all know, there are no perfectly ideal operating conditions in the world, and sometimes even following the instructions just helps reduce the chance of failure due to not understanding the basic rules of use. Then when we encounter difficulties in operation, we can refer to the following solutions:
Engine stalls regularly: This indicates a clogged air filter (clogged by dust, snow, other contamination). It has to be washed and dried.
The engine "whimps" immediately after starting: low oil level. To avoid this, check the oil level with a feeler gauge before starting. If there is a light indicator, during operation, it will notify you that it needs to be highlighted.
Engine stalls: Refueling is required. In order to prevent a sudden stop interfering with the operation of the appliance, it is necessary to track the liquid level according to the indicator light. If this is not the case, refuel at the intervals recommended by the instructions.
Generator does not start: If the generator set is new, used under normal temperature conditions, the reason is that there is no fuel in the tank. If there is fuel in the tank, but the generator has been down for more than a month, it means the gasoline has run out, let it out and refuel the tank. Also, the engine may not freeze due to oil freezing (requires preheating). If this is not the case, it is possible (in a 2-core engine) that the spark plug is full and should be removed, wiped clean, and screwed back in. In other cases, it is best to turn to an expert.
"Hoofs" when the generator starts: This indicates too much oil in the combustion chamber (most likely due to the generator flipping). The technician should keep the surface flat and stop for a while to allow the glass oil to enter the crankcase.
Overload indicator light on: Indicates that an overcurrent value has occurred. If it's a short-term phenomenon (eg, starting currents when high-power technology switches on), a high-quality generator will handle them. In the event of prolonged overload, the unit must be shut down and its cause eliminated. Otherwise, it will cause the starter and rotor insulation to break, resulting in short circuit and failure of the power station. In this case, it must be sent for repair at an expensive cost.
