Diesel Generator Tech

The rated speed of our Cummins diesel generator is 1500 rpm. For the generator set to maintain a stable speed, a governor is required. The governor can automatically adjust the fuel supply according to the load changes of the diesel generator set. It can be said to be an essential factor for the stability of the Yuchai diesel generator. Now, let's specifically talk about the two main uses of the governor: 1. When the speed of the Cummins diesel generator deviates from the set value, the governor can promptly make corresponding reaction actions. It also has the function of a restoring force to return the governor to its initial state. You should know that the spring in the centrifugal governor of our diesel engine parts is the part that generates the restoring force. Such a governor is also called a statically stable governor. However, a statically stable governor may also experience dynamic instability during the adjustment process. When the adjustment action is excessive and rever...

 According to the specific conditions of the generator's electromechanical equipment and the construction conditions, different methods can be used to install the generator rotor. For most medium - and small - sized generators, the shaft - connecting method is used to install the rotor. As a special tool, the extension (short) shaft for rotor installation is generally supplied by the manufacturer along with the generator. The normal procedure for installing the rotor of a Mercedes - Benz generator set is as follows: 1.Place a 0.8 - 1.0 mm thick cardboard along the entire length of the lower half - arc inside the stator. Move it back and forth at any time during the entire process of rotor installation to check if the rotor collides with the stator. 2.Position 1: The rotor is equipped with a short shaft and a rear bearing seat. The wire rope is hung on the part of the rotor cylinder close to the center for balance, keeping the rotor horizontal. Align it with the center of the sta...

Generally, a generator's lifespan depends on multiple variables. On average, diesel generators last from 10,000 to 30,000 hours of use, which could be upward of 25 years or more of running constantly. Proper operation and maintenance of generator are essential to long-term system reliability that ensures availability and uptime. Improper operation may reduce the lifespan of diesel generator. Below are common four mistake to avoid when using your diesel powered generator. Reduce the engine speed for a long time Revolutions Per Minute (RPM) is a measure of the speed at which a diesel generator operates. The RPM rating of a generator can affect its noise level. Generator frequency is the number of electrical cycles per second, measured in Hertz (Hz) and this is directly proportional to the engine speed. For example, a diesel generator has a RPM rating of 1500rpm and the frequency is 50Hz. The rated voltage is 400V. This mode of operation is relatively fast and therefore produces lou...

In a diesel generator, the piston ring groove is surrounded by a certain elastic metal open ring. This metal ring is called the piston ring. Piston ring is one of the key components of the diesel generator, its performance directly affects the quality and reliability of the diesel generator. According to the different uses of piston rings, piston rings are categorized into gas rings and oil rings. The main role of the gas rings is to form a sealed combustion chamber space with the piston, cylinder head and cylinder liner to prevent the high temperature and high pressure gases in the combustion chamber from flowing into the crankcase from the piston gap, as well as the cylinder wall. The main role of the oil ring is to ensure that the oil is evenly distributed on the inner wall of the cylinder liner, preventing the oil from entering the combustion chamber. If the oil enters the combustion chamber, the diesel generator will burn the oil, and blue smoke will come out of the exhaust pipe, ...

Diesel generators sets are a smart choice for backup power needs during power outages due to their reliability, durability and efficiency. They can also be used in remote sites where the power grid might be unreliable. However, standby diesel gensets could create safety hazards if not installed correctly. Here are some diesel generator room requirements and design considerations to keep in mind when installing and operating your generator. Where should a diesel generator be placed? Generator exhaust contains carbon monoxide gas, which can cause unconsciousness or death. Therefore, the installation location of generators is essential. The National Fire Protection Association (NFPA) has a standard for the installation and use of stationary combustion engines. Per NFPA 37, an enclosed generator set should be located outdoors, at least 5 feet from openings in walls and at least 5 feet from structures having combustible walls. Generators positioned outside the building shall be located in a...

This article continues to introduce the correct maintenance techniques for the "three filters" of diesel generators. 2、 Diesel filter   Several issues that are easily overlooked during the maintenance process of diesel filters:   1. Some users lose the upper and lower sealing rubber gaskets and oil cover of the diesel filter element during maintenance, allowing diesel to flow into the inner cavity of the filter element without resistance through the gap between the filter element and the filter, causing the diesel filter to lose its filtering and purification function.   2. Some users invert the position of the tray and spring of the diesel filter, or even throw them away, leaving the inlet and outlet holes on the diesel filter cover open, and diesel cannot be filtered and directly enters the fuel injection pump.   3. Some users, when maintaining a diesel filter, open it and find that the diesel inside is very clean. However, they do not realize that this is a false ...
