Considerations for Purchasing Cummins Diesel Generator Sets

When purchasing a Cummins diesel generator set, the selection process is of great importance. What aspects should we consider? First of all, a high - quality product is crucial. Secondly, generators with different powers and models should be used in suitable environments to achieve the effective power generation of the generator.

The actual output power of generators, water pumps, and power units is affected by factors such as altitude, temperature, and environmental humidity. As the altitude, temperature, and environmental humidity increase, the power of the generator will decrease in different proportions. When calculating the required power of the generator, these factors should be taken into account to avoid insufficient power during use.

Similarly, for electrical appliances of the same power, due to different types of electrical appliances, the starting currents vary greatly, and the power requirements for the generator also differ. Therefore, when purchasing products, users should first calculate how much power the generator needs to meet normal use. The specific references are as follows:

1.For resistive electrical appliances (such as light bulbs and electric stoves), the power ratio is 1:1.

2.For inductive electrical appliances (such as fluorescent tubes), the power ratio is 1:2.

3.For power tools and electric fans, the power ratio is 1:3 (for example, an angle grinder).

4.For air compressors, woodworking planers, machine tools, and milking machines, the power ratio is 1:4 (for example, a 1 - KW air compressor requires a 4 - KW generator).

Of course, generators, water pumps, and power units also need to follow certain operating procedures during use. For example, the engine oil should be filled to the proper level. For machines without an oil level gauge, the oil should be filled until it starts to overflow when the machine is placed horizontally. For machines with an oil level gauge, the engine oil should be filled strictly according to the requirements in the instruction manual. Over - filling the engine oil can easily cause problems such as black smoke emission and runaway, while under - filling can lead to engine seizure. Do not add engine oil to the machine's oil tank while the machine is running to avoid danger. Also, do not add fuel to the machine's fuel tank while the machine is working to prevent the machine from catching fire and being damaged.

The engine oil must be replaced after the first 20 consecutive hours of use or after being stored for 1 month to avoid excessive wear of the machine. After that, the engine oil should be replaced every 100 consecutive hours of use or every 3 months of storage. When the temperature is below 0°C, the diesel engine must use diesel with a grade corresponding to the ambient temperature of the equipment. Otherwise, the diesel will wax, and the generator will not start normally. When the temperature is below 0°C, the engine oil must be of a type corresponding to the ambient temperature of the equipment. Otherwise, it may easily damage the generator's power unit. Operators are required to carefully read the instruction manual before use and conduct inspections and operations as required by the manual to avoid unnecessary impacts and losses.
