The Characteristics Of The Fuel System Of Diesel Generator Sets

The fuel system is the heart of the diesel generator set. Before operating a diesel generator set, everyone must have a certain understanding of the fuel system of the diesel generator set. The fuel system must continuously supply fuel to the engine. Most fuel supply systems have a daily fuel tank and a backup (Oil storage) fuel tanks, and related piping systems, etc. In order to simplify the fuel supply system, the fuel tank is located as close as possible to the generator set room. If the local construction and fire protection regulations permit, the fuel tank can be installed next to the engine and its capacity should be increased as much as possible.

Common features of fuel systems include:

1.The pipeline connection from the fuel tank to the engine: the fuel supply pipeline leads the fuel from the fuel tank to the engine, and the return pipeline leads the fuel from the engine to the fuel tank.

2.Fuel tank vent pipe: The fuel tank has a vent pipe to prevent pressure or vacuum from accumulating during the filling and draining process of the fuel tank. When refilling the fuel tank, make sure that the metal-to-metal contact between the filler nozzle and the fuel tank is made to avoid sparks.

3.Overflow connection from the fuel tank to the drain pipe: This is necessary so that any overflow during the refilling of the fuel tank will not cause liquid to overflow onto the generator set.

4.Fuel pump: This transports fuel from the main fuel tank to the daily fuel tank. The fuel pump is usually operated electrically.

5.Fuel water separator/fuel filter: This separates water and foreign matter from the liquid fuel to protect other parts of the generator from corrosion and pollution.

6.Injector: This will atomize the liquid fuel and inject the required amount of fuel into the engine combustion chamber.

The above are common features of the fuel system. In addition, users should note that for small generator sets, the fuel tank is part of the generator sliding base, or installed on the top of the generator frame. For commercial applications, an external fuel tank may need to be installed, and all these facilities must be approved by the Urban Planning Department.

Diesel Power Stations | Könner & Söhnen Blog in Germany

Diesel power stations (DPS) are an effective, high-capacity solution for reliable power supply in the absence of the mains supply or when the power supply is not reliable. Diesel power plants are equally suitable for commercial and private applications.

These units incorporate an internal combustion diesel engine and a generator, which are mounted on a metal frame. Diesel power stations differ in functionality, power rating, startup system, etc.

In terms of the number of phases, there are two types of diesel power stations:

  • Single-phase;
  • Three-phase.

Könner & Söhnen offers a wide range of diesel power stations, allowing you to choose a model that best suits your needs.

Our diesel power plants are equipped with low-speed four-cylinder engines with liquid cooling. In addition to Deutz diesel generators, we also offer units equipped with diesel engines from other world-renowned manufacturers such as YangDong, Laidong, and Xinchai.

Applications of Diesel Power Plants

Diesel power stations are widely used in industry:

  • Construction;
  • Agriculture, farms and forestry;
  • Medicine;
  • Transportation;
  • Military;
  • On fishing vessels;
  • Camping;
  • Mains-independent power supply of residential buildings, cottages, country houses, office premises, stores, and various commercial premises.

A high-capacity diesel generator produces enough electrical energy to power a construction site, including lighting, power tools, and electrical appliances.

This diesel generator is a must, especially where the construction site is far from the local power supply network.

In agriculture, a diesel power plant comes in handy for powering hatcheries, farms, remote fields, and the like. They support heating, feed delivery, automatic irrigation systems, and other equipment.

When it comes to forestry, a powerful diesel generator provides lighting and operation of wood harvesting equipment, such as electric saws, electric wood chippers, etc.

As far as medicine is concerned, diesel power stations are essential for the operation of medical equipment that needs an uninterrupted power supply and must remain in operation all the time.

Diesel generators can be installed on ships, trains, or tractors to generate energy on the move.

Könner & Söhnen's portfolio of big diesel generators comprises units, suitable for domestic applications and small and medium-sized businesses.

Features of Diesel Power Stations

Könner & Söhnen diesel power stations are the ideal solution for reliable and uninterrupted power supply under all circumstances. Our stations have high efficiency and rugged design, allowing them to run smoothly for a long time. They are equipped with reliable diesel engines that provide maximum performance and durability. Diesel generators usually have a long service life, so purchasing one is your sound investment for future benefits.

Diesel power plants from TM Könner & Söhnen are reliable generator sets designed and built to European and American standards. With a simple control system, they require no additional training or special skills, though they are units for professional applications.

Let's take a closer look at the features of these power stations:

  • Diesel generator sets are powered by high-performance internal combustion diesel engines, which are known for their high efficiency and low fuel consumption. Könner & Söhnen diesel power plants are equipped with Deutz diesel engines or engines from other well-known manufacturers. Each station has an electronic or mechanical engine speed control and a state-of-the-art brushless alternator with AVR (Automatic Voltage Regulation).
  • Another feature of diesel power plants is their automatic start-up capability. With the external ATS system, they start automatically in the event of a power failure. They can also be started manually and run autonomously in places without a power grid.
  • We tried to design our diesel generators to be as compact as possible so that they can be installed on sites with limited space. With a well-designed layout of components, diesel generators are easy to access and maintain.
  • Moreover, because of an engine with liquid cooling and preheating function, our big diesel generators can operate even in adverse weather conditions and at extreme temperatures.
  • With a soundproof anti-vandal enclosure with a special galvanic coating, we have reached a minimal noise level during the operation of the diesel generator.

How to buy a diesel power plant, and what is a big diesel generator price?

The price is a crucial factor when it comes to purchasing a diesel power plant. Könner & Söhnen offers its customers reliable and high-quality diesel power stations at an affordable price. Diesel power stations from Könner & Söhnen have an optimal value for money. There are several models of diesel generator sets on our website. However, you can call our sales department and we will make an individual price offer for your chosen model.
