What should I pay attention to when purchasing Cummins generators?

Matters to be noted in the procurement of Cummins generator sets:

1. The purpose of the unit. Because the diesel generator set can be used in 3 situations, such as common, standby and emergency. Therefore, the requirements for diesel generator sets for different purposes are different.

2. Load capacity. The load capacity and the load change range should be selected according to different uses, and the single capacity of the diesel generator set and the standby diesel generator set capacity should be determined.

3. The use of environmental conditions of the unit (mainly refers to altitude and climatic conditions).

4. The selection of diesel generator, the selection of generator and excitation mode, and the selection of automation function of diesel generator.

In addition, it is necessary to pay attention to the selection of diesel generator set direct sales manufacturers to ensure the quality and after-sales service of the unit.

Select the Cummins generator set, and select the power of the diesel generator set according to the load used. It is best to use the common load at about 80% of the rated power of the diesel generator set. Because the diesel engine is the most fuel-efficient when the load is 80% of its rated power, it is also a kind of protection for the diesel engine itself.

After deciding to purchase a Cummins generator set, it is up to you to look at the configuration of the generator set. Just like buying a car, you look at these three parts: the diesel engine, the generator, and the control system.

The quality of the generator is related to the stability and service life of the voltage. The control system is preferably computer-controlled, which has a good protection effect on the generator.

When purchasing Dongfeng Cummins generator sets, general users are more concerned about: the choice of unit manufacturers, unit brand, configuration, unit ** and the choice of unit power. Let's start from these aspects and introduce the purchase precautions to users.

The selection of the unit manufacturer is a key step, a good manufacturer, the quality of the unit, after-sales service, etc., so we must choose a regular manufacturer.

Unit brand, Dongfeng Cummins is a very good unit brand. The unit has advanced technology, reliable performance, long continuous operation time, stable operation in various environments, and easy maintenance and maintenance. It has a wide power range and is widely used in various industries.

Whether the unit configuration needs to move trailers, silent boxes, rain shelters, etc., must be selected according to the needs of the work and the environmental conditions (the cost of optional configuration is additional).

The unit is determined by the unit brand, power, configuration, etc., depending on what kind of unit it is.

The choice of the power of the unit must be calculated and the appropriate power must be selected!

Cummins generators are of good quality, cost-effective, and worth choosing. Basic design features of Cummins diesel generator set:

The cylinder design of Cummins diesel generator set is sturdy and durable, with low vibration and low noise; In-line six-cylinder four-stroke, smooth operation and high efficiency; Replace wet cylinder liners, long life, easy maintenance; Two cylinders and one head, 4 valves per cylinder, full air intake, forced water cooling, small heat radiation, excellent performance.

Cummins' patented PT fuel system with unique overspeed protection; Low-pressure oil pipeline, less pipelines, low failure rate and high reliability; High-pressure injection, full combustion. It is equipped with a one-way valve for fuel supply and return, which is safe and reliable to use.

When choosing a Cummins generator, users can choose the appropriate unit configuration and unit power according to the work needs.

In order to ensure the quality and after-sales of the unit, when choosing the unit, you should go to the regular manufacturer to buy!

I used platinum with Stanford's generator set before, Stanford is owned by Cummins, and it is not bad. At that time, a full set of Cummins generator sets was also considered. More generator sets used in the oil field: Carter, Cummins, Volvo.

It's still okay, it's better than many domestic brands. However, when it comes to repairing and purchasing spare parts, it is not as convenient as the domestic brand.

Of course it's good. Cummins diesel engines are American technology. Better than our Weichai Yuchai and other engines. Of course, it's also a little higher.

To be truly Cummins, many suppliers are listed with Cummins; But what was sent was another matter.

You can consider using Anhui Cummins Stanford all-copper brushless automatic generator, which is of good quality and stable

This brand is also very famous.

Big brand, trustworthy. The quality control is strict, and we can best understand it.

Cummins is a Sino-US cooperation product, performance and quality are good, Huali Electromechanical is a manufacturer of Cummins generator sets, welcome to buy.

Cummins is the boss of diesel engines and definitely has the strength.

Cummins generators are a top-notch brand.

This brand is a better brand in China, the quality is OK, and the after-sales service is OK.

Among the four major brands of diesel generators, I prefer Inge, which is the most cost-effective.

I have studied their insulation structure, the stator end is fully wrapped insulation process, the mechanical structure is strengthened by insulating steel hoops, and the rotor is a triple insulated patented flat copper wire, which is more suitable for use in humid, corrosive environments, wind and sand and other environments.

Very good. It seems to be an American brand.

The old brand, the brand is good, look at what model.

Cummins generators use diesel engines to drive generators to generate electrical energy. According to the use of communication power supply, it can be divided into four categories: fixed, mobile, self-starting, and unattended. Cummins generator is a complex system, which is composed of diesel engine, power supply system, cooling system, starting system, generator, excitation control system, protection unit, electronic control unit, communication system, and main control system.

The engine, oil supply system, cooling system, starting system, and generator can be unified into the mechanical part of the Cummins generator. The excitation controller, protection controller, electronic control system, communication system, and main control system can be collectively referred to as the control part of the Cummins generator.

The speed of the Cummins generator determines the frequency of the output alternating current, so stabilizing the speed of the rotor is critical to ensuring that the frequency is stable. The speed of the turbine can be controlled in a closed-loop control mode, that is, the frequency signal sample of the alternating current emitted is taken and fed back to the control system that controls the opening and closing angle of the guide vane of the turbine to control the output power of the turbine, so as to achieve the purpose of stabilizing the speed of the generator.

With the continuous improvement of military, industrial modernization and automation, the requirements for the power supply quality of Cummins generators are also getting higher and higher. As the main power generation equipment, the improvement and development of synchronous generators are also relatively fast, and brushless synchronous generators and their excitation systems came into being, and are constantly developing and improving.

Many customers think that the loss file is that the Cummins generator does not need to take care of it after the normal start, in fact, this is not right, because the Cummins generator is the most prone to failure after the start. Therefore, at this time, it should also be regularly checked regularly, so as to ensure the normal operation of the Cummins generator set.

Why are there many Cummins generators of the same power and the same brand? It is not difficult to find out the reason after careful analysis. ** The difference is due to the following factors.

Cummins generator manufacturers are different.

Different Cummins generator manufacturers have different costs, different profits, and different assembled generators. The same is the first of Cummins generator 200kw, some factories have high costs and low costs, and some profits are high and low. In the end, the market selling price of Cummins generators will be different.

The configuration of the generators is different.

For example, the same 200kw Cummins generator, some manufacturers are equipped with Stanford generators, and some manufacturers are equipped with marathon generators. The Stanford generator is not the same as the marathon generator, so the assembled Cummins generator will naturally be different. It's not hard to see why.

Cummins generators** are different.

Some generator manufacturers are reporting to users without tax and freight, so that Cummins generators will be different.

Cummins generator accessories are available in different configurations.

The same 200kw Cummins generator, some with base fuel tank, including starting battery, including LCD module, including agarto relu heat electrical appliances, and some 200kw Cummins generators do not have any accessory facilities, such units are definitely different.

Genuine Cummins generator**.

The most hateful thing is that some manufacturers assemble decks of Cummins generators, in order to occupy the diesel generator market, put the trembling ** to a level to compete. Such a Cummins generator** will be different from**Cummins generator.

Application standards: ISO8528, ISO3046, BS5541, GB T2820-97;

Power Definition: Standby Power: A standby unit is used to provide continuous power (variable load) in the event of a mains failure. Overloading is not allowed in the rated working condition. This type of unit is rated as the peak value in continuous operation (as defined in ISO 8528-3);

Prime-use power: Prime-use units are suitable for situations where the generator set is supplied with continuous power to replace commercial electricity (with variable load). There is no limit to the number of hours per year and 1 hour of overload (10%) is allowed for every 12 working hours.

There are many models of Cummins generators, which are different because of the power of the unit, the technical parameters of the unit, and the use of the unit.

In the process of purchasing Cummins generators, the important thing is the configuration of the unit and the selection of power and power, which directly affects the use of the unit and whether the unit meets the working requirements.

Cummins generator refers to the diesel generator set powered by Cummins diesel engine, Cummins is a brand of diesel engine, which is a Sino-US joint venture. The model of Cummins diesel engine is named by the manufacturer, and there are many kinds.

The Cummins generator model is mainly named by each generator set manufacturer, such as HL500GF, which means that it is a 500KW generator set.

Cummins generators have good quality, stable performance and low fuel consumption, and are used in public utilities, education, electronic technology, engineering construction, industrial and mining enterprises, animal husbandry, communications, biogas engineering, and other industries. About the model of Cummins generator, it depends on the power of the unit and technical details, take 200kw Cummins generator as an example to introduce the technical parameters of the model!

There are many models of Cummins generators, this is the original Wuxi Stanford was acquired by Cummins and changed to Cummins generators, in fact, the original Cummins does not make generators, only produces engines, after the acquisition of Cummins has engines and generators, assembled is a set of Cummins diesel generator sets. There are so many models, you can take a look: Cummins Generator Technology China******.

Depending on the actual demand situation on your side, standby power or prime power supply, and how much load it brings.

Cummins Diesel Generator Generator Set Advantages:

Excellent quality, low fuel consumption, low noise, high output power, reliable performance. Its reliable stability, economy, power, durability and environmental safety are welcomed by users at home and abroad. Sino-US joint venture Dongfeng Cummins and Cummins engines have small size, light weight, low fuel consumption, high power, reliable work, excellent accessories and easy maintenance.

It adopts electronic governor, which has the protection functions of high cooling water temperature, low oil pressure, overspeed alarm and automatic stop.

Things to pay attention to when buying a diesel generator set:

Confusing the relationship between kva and kw. Exaggerate the power of KVA as KW and sell it to customers. In fact, kva is the apparent power, kw is the effective power, and the relationship between them is ikva=.

Imported diesel generator sets generally use KVA to express the power unit, while domestic electrical equipment is generally expressed in KW, so KVA should be converted into KW by 2% when calculating power.

Regardless of the relationship between the long-line (rated) power and the backup power, only one "power" is said, and the backup power is sold to customers as long-line power. Actually, backup power = long line power. Moreover, the backup power can only be used for 1 hour of 12 hours of continuous operation.

I heard that the quality of the Cummins generator from Yatong Company** is not bad, you can go and see it.

Excellent power The maximum output power can reach 500kw, and the maximum output torque ensures abundant power in various use conditions.

Ultra-low fuel consumption. The use of Cummins XPI ultra-high pressure common rail fuel injection system and CTT high-flow turbocharger, combined with Cummins' advanced power cylinder design and electronic control system, greatly reduces fuel consumption and ensures excellent fuel economy of the engine in different working conditions and applications.

Outstanding reliability.
