Cummins diesel generator overview

Criterias of choice

Determining the required power

By purchasing a diesel silent 3 kW electric generator, it is easy to ensure peace and quiet at the facility. But it will not be possible to "feed" sufficiently powerful electrical devices, machines and apparatus. Therefore, on serious industrial, construction sites and in other similar places, you will have to put up with significant noise.

But returning to the calculation of the required power, it is worth pointing out for a start that it is carried out according to three important criteria:

• the nature of energy consumption;

• the total capacity of all consumers;

• the value of starting currents.

It is generally accepted that equipment with a capacity of 10 kW or even less is needed for repair and construction. Such devices deliver the most stable current. Power from 10 to 50 kW allows the generator to be used not just as a reserve, but also as the main source of power supply. Mobile plants with a capacity of 50-100 kW are often converted into a stationary power source for the entire facility. Finally, for large enterprises, cottage settlements and transport infrastructure, models from 100 to 1000 kW are needed.

Purpose and operating conditions

If these parameters are not taken into account, the repair of generating equipment will have to be carried out very often. And it is not a fact that it will really help. So, household generators, even the most powerful ones, are unlikely to be able to work for a long time at maximum modes, feeding the production line. And industrial-grade products, in turn, cannot pay off at home.

With regard to normal operating conditions, then for almost all models they are as follows:

• ambient temperature from 20 to 25 degrees;

• its relative humidity is about 40%;

• normal atmospheric pressure;

• height above sea level no more than 150-300 m.

But a lot depends on the execution of the generator. So, the presence of a protective casing allows you to work confidently even in severe frost. The level of permissible humidity increases to 80-90%. Still, normal use of a diesel engine is unthinkable without a stable air flow. And we must also take care of protecting even the most reliable and proven devices from dust.

Required number of phases

A three-phase diesel power plant can supply current to both three-phase and single-phase "consumers". But this does not mean that it is always better than the single-phase version. The fact is that more than 30% of the power cannot be removed from a single-phase output on a three-phase device. Rather, it is practically possible, but no one guarantees the safety and stability of work.

The following types of Cummins devices are distinguished:

• in the casing;

• in a block container;

• AD series.

engine's type

Cummins is ready to supply 2-stroke and 4-stroke diesel generators. The rotation speed is also different. Low-noise devices spin at 1500 rpm. The more advanced ones make 3000 rpm, but they make much louder noise. A synchronous unit, in contrast to an asynchronous one, is suitable for powering devices that are sensitive to voltage drops. There is also a difference between engines in the following properties:

• limiting power;

• volume;

• the amount of lubricant;

• number of cylinders and their location.

Peculiarities

When characterizing Cummins generators and diesel power plants produced by the same company, it should be emphasized that they are produced by a genuine industrial giant. Yes, a giant of an industry that has already been declared unnecessary and archaic organizations. The company has been operating since 1919 and its products are well known in various countries of the world. The production of diesel and gas piston power plants, as well as parts and spare parts for them, are the priority areas of Cummins activity.

The compact generator sets from this manufacturer are available in capacities ranging from 15 to 3750 kVA. Of course, the compactness of the most powerful of them is revealed only when compared with competitors' products. The engine running time is very long. For some advanced versions, it exceeds 25,000 hours.

It is also worth noting:

• advanced radiators;

• the strictest implementation of basic technological and environmental standards;

• thoughtful management (technically perfect, but at the same time not causing difficulties even for inexperienced people);

• ease of daily operation and maintenance;

• debugged top-level service.

The lineup

It should be noted right away that Cummins diesel generators are divided into two groups - with a current frequency of 50 and 60 Hz. The first group includes, for example, the C17 D5 model. She is able to develop power up to 13 kW. The device usually has an open design scheme. It is also delivered in a container (on a special chassis) _ because this generator turns out to be a true "universal", suitable for a variety of tasks.

Other parameters:

• voltage 220 or 380 V;

• hourly fuel consumption at a power of 70% of the maximum - 2.5 liters;

• starting with an electric starter;

• cooling liquid type.

A more powerful and advanced option is the C170 D5 diesel generator. The manufacturer positions its product as a reliable solution for uninterrupted power supply to various objects. In the main mode, the power is 124 kW, and in the standby mode, 136 kW. Voltage ratings and starting method are the same as for the previous model.

If we talk about generators with a current frequency of 60 Hz, then the C80 D6 attracts attention. This three-phase machine can deliver up to 121 amps.

The total power is 58 kW. In standby mode, it increases to 64 kW. The total weight of the product (including the fuel tank) is 1050 kg.

Finally, consider a more powerful 60 Hz generator set, more specifically the C200 D6e. The device generates 180 kW of current in normal daily mode. In the forced temporary mode, this figure rises to 200 kW. The delivery set includes a special cover. The control panel is version 2.2.

About Cummins

Cummins was founded in the USA in 1919. Dynamic development and efficient activities have made it a recognized leader in the production of diesel engines with a capacity of 31 to 3500 hp. and brought it to the first place in the production of engines with a capacity of 50 hp. and above. In our country, Cummins engines appeared in the early 70s along with the supply of heavy mining equipment. Cummins diesel generator sets are known for their reliability and unpretentiousness. The engines developed by Cummins operate reliably on domestic fuel in the most difficult conditions throughout Russia, while being one of the most economical and environmentally friendly.

Cummins offers any required power: from an 8 kW diesel generator for backup power supply to a power complex with a total capacity of 30 MW.

Deliveries of diesel generator sets to the Russian market are carried out from a plant in Great Britain, which manufactures units up to 5000 kVA, with a frequency of 50 or 60 Hz with an output voltage of 0.4 to 11 kV. Simultaneously with the production of generator sets, the company produces all the components for such plants: engines, generators, automation systems and makes final assembly.

Diesel generators are equipped with control systems for monitoring basic parameters and automatic parallel operation without additional synchronization and load sharing systems. In addition, they can be equipped with remote monitoring and control systems from a personal computer.
