Regularly Check The Wear of Fixing Bolts of Diesel Generator Set

How to regularly check the wear of the keyways and fixing bolts related to diesel generator sets, using standard high-pressure oil pipes. During the fuel supply process of the fuel injection pump, due to the compressibility of diesel and the elasticity of the high-pressure fuel pipe, high-pressure diesel will form pressure fluctuations inside the pipe. The transmission of pressure waves inside the pipe requires a certain amount of time. To ensure consistent fuel supply interval angle, uniform fuel supply, and stable operation of the diesel generator set, the length and diameter of the high-pressure fuel pipe are selected through calculation.

Therefore, when the high-pressure oil pipe of a certain cylinder is damaged, a standard length and pipe diameter oil pipe should be replaced. In practical use, due to the lack of standard oil pipes and the use of other oil pipes instead, regardless of whether the length and diameter of the oil pipes are the same, there is a significant difference in the length and diameter of the oil pipes. Although it can be used for emergency purposes, it will cause changes in the fuel supply advance angle and quantity of the cylinder, resulting in unstable operation of the diesel generator set. Therefore, it is necessary to use standard high-pressure oil pipes in use.


And it is necessary to regularly check the wear of the relevant keyways and fixing bolts of the diesel generator set. The relevant keyways and bolts mainly refer to the camshaft keyways, coupling flange keyways (oil pumps that transmit power through couplings), half round keys, and coupling fixing bolts. The camshaft keyway, flange keyway, and semicircular key of the fuel injection pump may wear out due to long-term use, causing the keyway to become wider, the semicircular key to not be firmly installed, and the fuel supply advance angle to change; The heavy key falls off, causing power transmission failure. Therefore, it is necessary to regularly inspect, repair or replace worn components in a timely manner.

Diesel Generator Power Ratings: Standby vs Prime vs Continuous

Diesel generator sets are commonly used in a variety of sectors due to their dependable performance and high efficiency. They can be used for emergency power supply in the event of a power cut or used in places without connection to a power grid. When selecting a diesel generator for your home or business, you need to consider many factors, such as generator’s ratings. In this article, we’ll explain the three basic rating types - standby, prime, and continuous in diesel generators. ISO-8528-1:2018 defines basic generator set rating categories based on four operational categories: Emergency Standby Power (ESP), Prime Power (PRP), Continuous Power (COP) and Limited-Time Running Prime (LTP). Read on and learn the application of power ratings for engines used in generating sets. Standby Power Rating Standby Power(ESP) is used to supply emergency power when the external power supply is interrupted, such as power outages. Standby power rated generators can supply reliable electricity as t...

How to Connect A Diesel Generator to Your House?

Diesel generators are fuel-efficient and reliable, which can almost meet the power needs of any application. If you want to power the whole house during power shortages, it’s a good choice to choose a diesel generator set as the backup electricity supply. But how to connect a diesel generator to your house? Read on and you will find the answer. Options to connect a diesel generator to your home   Keep in mind that never plug your generator directly into the mains, or it will cause back feeding, damage your appliances and be life-threatening for utility workers. Generally, you can choose to connect a generator to your house by using extension cords or a transfer switch. Understanding the difference between them is helpful for you to choose the right type. Extension cords   Typically, extension cords are suitable for smaller diesel generators that used for short term. They require no installation and are cost-effective. If you need to power only some basic appliances such as...

What Should You Pay Attention to in Routine Maintenance of Diesel Generator Sets

In modern society, the stability of power supply is directly related to the operation efficiency of enterprises and people's quality of life. Diesel generators have become an indispensable backup power supply or main power source in various industries due to their high efficiency, durability and reliability. However, to ensure the smooth operation and optimal performance of the generator sets, regular maintenance is essential. Here is what you need to pay attention to in the routine maintenance of diesel generators. Keep your generator clean It’s important to keep the generator’s exterior and the generator room clean. Regularly remove any dirt, dust, or debris that may accumulate to on the generator’s surface. This is not only for the sake of beauty, but also for the smooth operation of the unit. Cleaning the generator’s exterior, air intake vents, exhaust outlets and generator room can effectively reduce the risk of generator overheating. In addition, check if the connection bol...
