Factory Backup Generator

Model NO.:
Factory Backup Generator
Factory backup generators are generator sets that are provided to ensure the basic production and life of the factory when the mains power supply is switched off or the power supply is interrupted for other reasons.

Detailed description

1.Basic introduction of Factory Backup Generator:

With the development of science and technology, some power users and electrical equipment have higher and higher requirements for the reliability of power supply. In order to ensure the reliability of power supply, in the power supply system of the factory, in addition to the dual power supply, a backup generator is set up inside to ensure uninterrupted power supply to some important places and equipment in emergency situations.

2. The brand and power of Beidou Power company's backup generator


Beidou can provide customers with the choice of factory backup generator brands including Perkins, Volvo, Cummins, Yuchai, Shangchai, Weifang and so on. The power range includes 2kw ~ 2800kw.

3. How to select and purchase Beidoufactorybackup diesel generator sets ?

1Load analysis of diesel generator sets

There are many factors that influence the size of diesel generator sets selected by power factory, among which are the characteristics of system power load. Is an important factor. Before operating a diesel generator set, the factory must carefully consider the following:

Is it used as a utility or a backup generator?

Consider increasing the system power consumption in the future;

Allowable voltage drop of the system;

Motor starting conditions.

2Diesel generator power calibration:

Generally speaking the diesel generator set for factory use is a public unit. It can supply rated load for 12 hours (including the ability to run for 1 hour at 110% of rated power). In the case of few mains failures and short power supply time, the factory can use generator sets with power calibration as a backup unit. It does not exceed 200 hours per year and operates at 80% of average maximum power. In addition, the operating time at 100% of maximum power must not exceed 25 hours per year.

3Attentions when matching diesel generator sets and three-phase motors The most commonly used in mechanical engineering is three-phase AC induction motors. Due to their starting characteristics, these motors are directly connected to the power system. If it starts directly online, it will generate a surge current up to 6 times the rated current of the motor. After the soft-start device is configured, the starting current is very stable and will not cause the shock of the diesel generator set. When selecting the capacity of a diesel generator set and a three-phase motor, it is recommended to consider the motor capacity to be 1.5 or 1.5 times the safety factor (must be a soft start method).

4.Maintenance of Beidou factory backup Diesel Generator Set

Thebackup diesel generator of the factory is an independent power generation device, which mainly provides emergency power failure. In fact, most time units are in backup and the chances of actually putting them into use are relatively small. Testing equipment is usually the main method, and lack of better detection and maintenance methods. But such emergency backup power is essential. How to ensure that the power of the generator can be used in emergency situations under normal circumstances, is safe and reliable, and can be cut off immediately after shutdown.

(1)Check the battery pack.

Since the backup power is not often used, whether the generator can start normally depends on the maintenance of the battery. If there is a problem with the battery pack, it is more common to have no voltage and current. At this time, the sound of the solenoid valve in the starting motor can be heard, but the shaft cannot move. There are three reasons why a battery pack cannot be stopped:

Stopping the battery during a test run will cause the battery to run out.

This mechanical oil pump is driven by a belt. At the rated speed, the amount of oil pumped is large, but the battery pack is insufficiently powered, which causes the shut-off valve spring leaf to have insufficient suction power at the solenoid valve and stop from the four oil ports. The fuel produced cannot be stopped.

(2)Check the solenoid valve.

When the generator was running, people summed up a set of"one look, two listen, three touch, four smell"inspection methods. Listening at startup is an important step. Take the Cummins generator as an example. Just press the start button and it will start after three seconds. Two"clicks"can be heard in these three seconds. Once you do not hear a second sound, check that the start solenoid is working properly. Of course, if the solenoid coil explodes, the generator will certainly not start.

(3)Check the diesel and lubricating oil.

As the unit is at a standstill for a long time, various materials of the unit itself will undergo complex chemical and physical changes with engine oil, cooling water, diesel, air, etc., causing the unit to"discharge". For this reason, attention should be paid to the issue of petroleum. For fire safety, diesel fuel tanks are usually placed in closed rooms. As the water vapor in the atmosphere condenses due to temperature changes, water droplets adhere to the inner wall of the fuel tank and flow into the diesel engine, causing the diesel engine to exceed its water content. If diesel enters the diesel high-pressure oil pump, it will corrode the precision coupling and plunger, which will seriously damage the unit. Generator lubricants have a shelf life. Lubricating oil has a long storage time, and its physical and chemical properties will change, which will cause the unit's lubricating condition to deteriorate during work and easily cause damage to generator components.
