How much is a 3 kilowatt three phase electric diesel generator

Hello, in a nutshell, it's a diesel generator that drives the generator to run.

In the cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injector, and under the extrusion of the piston, the volume is reduced, and the temperature rises rapidly to reach the ignition point of the diesel. The diesel fuel is ignited, the gas mixture burns violently, and the volume expands rapidly, pushing the piston downward, which is called 'work'. Each cylinder works in a certain order, and the thrust acting on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate.

By installing the brushless synchronous alternator coaxially with the crankshaft of the diesel generator, the rotor of the generator can be driven by the rotation of the diesel generator, and the generator will output an induced electromotive force by using the principle of 'electromagnetic induction', and the current can be generated through the closed load loop.

Here only the most basic working principle of the generator set is described. A serviceable, stable power output requires a range of diesel generators and generator controls, protection devices, and circuits.

Small diesel generator 3 kilowatts, household single-phase 220v generator set 3 kilowatts 3000w all-in-one machine**2,000 or so. Different brands of small diesel generators are different in 3 kW**, depending on what kind of unit it is.

Small diesel generators have the advantages of small size, low noise, low vibration, high quality and low price, and users can choose the right unit according to their specific work needs.

The open-frame 3 kW equal power 220V380V diesel generator** is about 3200, and the silent 3 kW generator** is about 4000.

1 (horsepower) = kilowatts.

Considering the power factor, and the fact that the diesel engine is not suitable for full power operation, 3 a 6 horsepower diesel engine is fine.

7 horsepower is equivalent to kilowatts. But there's also the power factor and so on.

3KW is about equal to 4HP, and the prime mover is greater than the motive, so it is necessary to use a diesel engine greater than 4HP for power.

At least 5 hp or more diesel engine, because the generator may have a short period of overload.

According to the market in January 2020**, diesel generators are between 4,000 yuan and 1,000 yuan.

The basic structure of diesel engine: it is composed of cylinder, piston, cylinder head, intake valve, exhaust valve, piston pin, connecting rod, crankshaft, bearing and flywheel and other components.

Diesel engine starting is to rotate the diesel engine crankshaft by manpower or other power, so that the piston reciprocates up and down in the cylinder closed at the top. The piston completes four strokes in motion: intake stroke, compression stroke, combustion and work (expansion) stroke, and exhaust stroke.

The general power of diesel generator sets is from 8 to 2000kw, and the brands of diesel generators include Cummins generators, Perkins generators, Volvo generators, Yanan generators, Yuchai generators, Weichai generators, Shangchai generators and other brands. Generally, diesel generators include stationary generators, mobile generators, silent generators, containerized generators and other styles.

Application fields of diesel generator sets.

1. Mines. The diesel generator set can be fixed on the foundation as a whole, positioned for use, or installed on a trailer for mobile use. Therefore, it is widely used in mines.

2. Marine and port.

Large ports have a large number of ships calling at each day, and the powerful diesel engines on board the ships must run continuously to keep the ship's equipment and support systems running.

3. Field construction sites.

Due to its small size, flexibility, lightness, complete facilities, easy operation and maintenance, it is widely used in field construction sites and other departments as a backup power supply or temporary power supply.

Fourth, municipal machinery.

Yanan Motor Tips: Diesel engines are widely used due to their high thermal efficiency. Off-highway diesel engines are the main body of the off-highway engine market, mainly used in agricultural machinery (such as tractors), construction machinery (such as excavators, loaders, bulldozers), material handling machinery (such as forklifts) and multi-purpose equipment (such as generator sets, pumps), etc.

5. Building construction.

The high-performance and stable generator set adopts a low-noise design to ensure that the replacement power system must be able to provide power immediately in the event of a mains power outage. Support the normal operation of all types of buildings and facilities around the world.

Sixth, special for breeding.

Farms are generally built in relatively remote places, and electricity is inconvenient, so generators are a must-have magic weapon for major farms. Aquaculture is an industry that uses more generator sets.

Small diesel generators** are generally3,000 to 60,000 yuan a unit, and there are several hundred cheaper ones

Factors influencing diesel generators**:

First, the market. 1. Market demand: Diesel generators, like ordinary commodities, will be affected by market demand.

If the demand for diesel generators in the market increases, then it will, and conversely, if the demand for diesel generators decreases in the market, then the demand for diesel generators will decrease.

2. Market supply: The market supply also affects the quality of diesel generators. If the market demand is greater than the market supply, then the diesel generator will follow, on the contrary, if the market demand is less than the market supply, then the diesel generator will decline.

Second, the brand. 1. The brand of diesel generator has a very important impact on the quality of diesel generator, which is the same as ordinary commodities.

2. Generally speaking, due to factors such as brand premium and after-sales service, the higher the brand awareness, the higher the quality of diesel generators.

3. Generally, imported brand diesel generators** are higher than domestic brand diesel generators**.

4. Under the condition that the budget permits, it is recommended to purchase a well-known diesel generator to get better quality assurance and after-sales service.

How much horsepower diesel engine does a three-kilowatt three-phase generator drive?

Hello dear, the three-kilowatt three-phase generator has an output power of 3000 watts, and a diesel engine is needed to drive the generator to rotate through mechanical transmission to generate electrical energy. The specific amount of horsepower required for a diesel engine depends on the speed and efficiency of the diesel engine, which can usually be calculated according to the following formula: power (horsepower) = generator output power (watt) efficiency per horsepower diesel engine speed (rpm) Among them, the efficiency of the diesel engine is generally between 20% and 40%, and the speed can be set according to the actual use.

For example, a diesel engine with an efficiency of 25% and a speed of 1000rpm per horsepower will require about 3000 watts 1000 rpm horsepower = 12 horsepower It should be noted that the actual situation may be affected by a variety of factors, such as the configuration of the diesel engine, maintenance, use environment, etc., so the final result may be biased. Please pay attention to the check, thank you.

How much horsepower diesel engine does a three-kilowatt three-phase generator drive?

Hello dear! The three-phase generator of three kilowatts needs about 18-20 horsepower to drive the diesel engine. Because there is a certain loss between the horsepower of the diesel engine and the output of the generator, usually it is one watt of horsepower watt output, so the diesel engine of about 18-20 horsepower can drive the three-phase generator of three kilowatts.

In addition, when choosing a diesel engine, you need to consider the working environment of the generator. Due to the heat generated by the three-phase generator, when arranging the location and environmental control of the engine room, the place and direction of heat discharge should be considered to ensure the performance of the diesel engine and the heat dissipation requirements of the generator. In addition, when installing the diesel dry oil machine, it is also necessary to pay attention to the connection between the diesel base lifter and other components to ensure the normal operation of the power generation system.

How much horsepower diesel engine does a three-kilowatt three-phase generator drive?

Hello <>

How much horsepower does a three-kilowatt three-phase generator need to be driven by a diesel engine? For this question, we need to understand some basic concepts of building segments. First of all, three kilowatts is the output power of the generator, indicating that the generator can provide 3000 watts of electricity.

Whereas, horsepower is a unit of power and is used to indicate the output capacity of an engine. Here, we need to know a basic conversion relationship: 1 horsepower = 746 watts.

So, we can calculate the number of horsepower required by the following formula: Generator output power = number of horsepower. Substituting the value of three kilowatts, we can get:

3000 In other words, a diesel engine with about horsepower is needed to drive a three-phase generator of three kilowatts. It should be noted that in actual production, it is also necessary to consider the efficiency, speed, capacity and other factors of the diesel engine to select the appropriate diesel engine. In addition, factors such as the load and stability of the generator will also have an impact on the requirements of the diesel engine.

Moreover, it is necessary to take into account the change of load in order to adjust the working load of the diesel engine and ensure the normal operation of the power generation system. Therefore, the three-kilowatt three-phase generator needs a diesel engine with about horsepower to drive. <>
