What should I pay attention to when purchasing Cummins generator sets?

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.

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!

1. Before each start-up, you should do a good job of "preparation before starting", and remember that the diesel engine must start without load. 2. Check whether the water tank is full 3. Check the oil ruler, the oil is generally between "static full" and "dynamic full" in the cold engine state. Fourth, whether the diesel fuel pipe is unblocked.

5. Whether the battery connection line is correct. 6. Open the diesel engine key, press the ignition button, wait for the diesel engine to idle for 2-3 minutes, and the fuel pedal makes the speed reach 1500r min, and the frequency is 50-52 (Hz) 7. When stopping, the load should be unloaded, and then the generator set will be lifted and broken, and then the governor control handle will be adjusted, and the speed will be gradually reduced to about 750 r min, and the parking cable will be pulled after 3-5min operation.

There are many Cummins generator manufacturers, but you must choose a manufacturer with better comprehensive strength.

There are many diesel generator set manufacturers, for an enterprise, the quality of the product is the lifeblood of the enterprise, because now with the rapid development of the economy, the number of products and product types sold on the market are more.

The competition between enterprises is increasing, in order to enhance the competitiveness of enterprises and make enterprises stand out in such a fiercely competitive market, then enterprises must strictly control the quality of products, which also makes diesel generator set manufacturers continue to develop. When choosing a manufacturer, we must choose a regular manufacturer to ensure the quality and after-sales of the unit.

1. Choose the OEM factory of well-known diesel engine manufacturers to ensure the quality and after-sales of the unit.

2. Inspect the scale and corporate culture of the manufacturer, and choose a satisfactory manufacturer 3. In addition, we should pay attention to the selection of the unit brand and unit configuration, and communicate with the manufacturer on specific matters!

There are many Cummins generator set configurations, which are divided into standard configuration and optional configuration. The standard configuration is included in the package**, while the optional configuration is charged separately.

What are the optional configurations of Cummins generator sets: oil, diesel, water jacket, anti-condensation heater, split daily fuel tank, integrated base fuel tank, battery floating charger, rainproof unit (cabinet), self-protection, self-starting unit control screen, silent unit (cabinet), unit control screen with "three remote" function, mobile trailer power station (cabinet trailer), ATS automatic load conversion screen, silent mobile power station (cabinet trailer) and so on.

When purchasing Cummins generator sets, users should choose the appropriate unit configuration according to the work requirements and environment and other factors.

There are a few things to keep in mind when using a diesel generator:

1. In order to prevent the armature coil from being burned out, the diesel generator cannot exceed 10 seconds each time it starts to work, and the interval between the two starts must be more than two minutes.

2. When the diesel generator is running, if the driving gear can not be meshed with the gear ring, the start button needs to be released immediately, and the starter needs to be completely stopped before it can be started for the second time, the purpose is to prevent them from colliding with each other and causing damage.

3. If you need to use diesel generators in colder areas, you must use antifreeze.

4. After the diesel generator unit starts, you have to quickly release the start button, and then the drive gear will return to the original position.

5. Regularly add grease to the bushing of the rear cover of the diesel generator to prevent Liangwei from wearing the bushing and bearing due to hair drying.

The precautions for the use of Cummins generator sets are as follows:

1. Check the indicating instruments according to the specified time, pay attention to the pressure of the lubricating oil and whether the water temperature changes. The pressure of the lubricating oil shall not be less than 150kpa, and the temperature of the cooling water shall not be higher than 95;

2. Check the oil level of the crankcase, the fuel tank and the water level of the radiator, which should be supplemented if it is lower than the normal position;

3. Observe whether the instruments and alarm indicators of the distribution panel are normal. Where the red light is on, it means that there is a fault, and the green light is the normal operation indicator;

4. Check whether the charger is charged normally;

5. Listen to whether the sound of each part of the machine is normal;

6. The shell of the hand mold body, the shell of the bearing part, the oil pipe, and the water pipe, whether the temperature is normal;

7. Pay attention to whether the generator or electrical equipment has any peculiar smell such as burnt;

8. If there is a bad situation, it should be dealt with and solved immediately; Serious cases should be shut down;

9. Where the fault is stopped, the fault must be eliminated, and then the repeated hand button on the motor group must be pressed before the unit can be operated again;

10. For each operating parameter, record no less than twice per shift.
