As an emergency backup power source after a power outage, diesel generator sets are mostly in standby mode. Once a power outage occurs, diesel generator sets play a crucial role. However, it was not until the use of diesel generator sets that performance issues were discovered. Many users did not realize the importance of false load operation of diesel generator sets, which delayed the normal production and operation of the enterprise. This mistake is very serious. In order to extend the service life of diesel generators and ensure the normal operation of enterprises, and with maintenance costs much lower than repair costs, inspection and maintenance work should be treated as daily work. The purpose of detecting and maintaining AC false loads for  diesel generator sets   1. Detecting diesel generator sets   By detecting the AC false load used for maintenance of diesel generator sets, the unbalanced load capacity of diesel generator sets can be detected, ensuring steady-st...

A diesel genset may malfunction after a certain period of use. It’s crucial to know how to troubleshoot diesel generator issues. Disassembly is an important part of the generator set repair work. If you want to dismantle and repair the generator yourself, you need to make some preparations and follow the normal disassembly methods to prevent damage to the machine or other accidents. In this article, Dingbo Power introduces several important things that you need to know about disassembly of diesel generator. Principles of disassembly To prevent various accidents and ensure smooth disassembly of the genset, the following principles should be followed during disassembly: Firstly, understand the structural characteristics of  diesel genset  as well as its components and how it works. Secondly, for those diesel generators without technical data and instructions, be sure to record the torque of the disassembling parts when dismantling the generator sets. Thirdly, do not extend the s...

When the parallel controller of Zhongzhi HGM9510 generator set detects a warning signal, the controller only warns and does not stop the machine. What do the warning signals of the controller represent? Top Power shares with users. 1. Overspeed warning   When the overspeed warning is enabled, the controller sends a warning signal when it detects that the speed of the  generator set  exceeds the set overspeed warning threshold.   2. Underspeed warning   When the underspeed warning is enabled, the controller sends a warning signal when it detects that the speed of the generator set is less than the set underspeed warning threshold.   3. Speed signal loss warning   When the controller detects that the speed of the generator set is zero and the speed signal is lost, the action type selection warning is triggered, and the controller issues a warning signal.   4. Power generation over frequency warning   When the power generation over frequency war...

  Generators plays an important role in providing electricity and   three phase generators   may be familiar to many businesses and building managers. As a powerful energy source, 3 phase generators are suitable for use in industrial or commercial settings. In this article, let’s look at the three phase generator price and the factors you need to consider when buying one. What Is A Three-phase Generator? There are two main types of generators: three-phase and single-phase. A single-phase generator is an electric generator that uses one alternating current (AC) phase to produce electricity. This type of generator uses a single conductor active wire and a neutral wire to complete a circuit. It can supply up to 240 volts of power and is typically used in residential applications. Three phase electric power is a common type of AC used in electricity generation, transmission, and distribution. A 3-phase generator uses three active wires which are all offset by 120 degrees and ...

Continuing from the previous text, we will introduce to diesel generator users how the exhaust turbocharger of a diesel generator set is assembled. 7. Apply clean engine oil to the shaft seal that has been installed with an elastic sealing ring, and then install it into the corresponding seat hole on the compressor end air seal plate. Before installation, offset the opening positions of the two rings by 180 degrees, and insert the "o" - shaped rubber sealing ring into the groove on the outer circumference of the compressor air seal plate. In order to facilitate pressing into the middle shell, apply some thin engine oil to the outer surface of the rubber sealing ring, and then press it into the middle shell body.   8. After aligning the dynamic balance marks on the rotor and compressor impeller, put on the compressor impeller, screw on the self-locking nut and tighten it until it aligns with the dynamic balance mark on the shaft end face [the tightening torque at this time is ...

Many users don't follow the operational procedures when using diesel generator sets, which will affect the normal operation and lifespan of generators. To help you out with this, here are 7 common mistakes to avoid when using   diesel engine generators . 1. Loading without prelubrication and warmup after cold starts on diesel generators Cold starting a diesel generator without prelubrication and warming up can lead to premature failure or more friction and wear on important parts. To ensure smooth generator startup and operation, let the diesel engine run at idle speed for a period of time to heat up and then turn it into normal operation when the oil temperature becomes normal and the oil supply is sufficient. Avoid pressing the accelerator hard after cold starting the generator, this may damage the machine. 2. Adding coolant improperly Before starting the diesel generator, ensure that there is enough coolant on the reservoir and do not add hot water immediately. Before adding coo...

The exhaust gas turbocharger can effectively utilize the pulse energy of the exhaust gas emitted by the diesel engine to drive the radial turbine, driving the centrifugal compressor impeller coaxial with the turbine to rotate at high speed, increasing the air pressure, and entering the cylinder through the   diesel engine   intake pipe to increase the charging amount of the diesel engine, which can provide more diesel for combustion, thereby improving the output power and economy of the diesel engine. Before assembly, all parts of the exhaust gas turbocharger should be carefully cleaned (including various tools used for assembly). The parts should be wiped with a lint free soft cloth and placed in a clean place. At the same time, all parts should be inspected and qualified before assembly. If necessary, the dynamic balance of the turbine rotor, compressor impeller and its combination components should be recalibrated and reassembled after picking. The assembly process and prec...
