Diesel Generator Tech

The generator fuel pump is the "heart" of the engine's fuel supply system. It is a device that continuously draws fuel from the fuel tank and provides the fuel system with fuel at a specified pressure and flow rate. Based on the functions of the generator fuel pump, it can be known that the performance of the fuel pump will directly affect the working performance of the engine. Therefore, it is necessary to carry out corresponding preparatory work before using the fuel pump. To ensure the normal use of the generator, debugging the fuel pump is the primary preparatory work. We must install and debug it on a dedicated test bench according to the fuel pump calibration data sheet. Currently, the flowmeter method is mostly used, and the specific steps are as follows: Preparation before debugging The fuel pump and injector have been debugged on the test bench. The generator is in good technical condition and has entered the hot - running state. The fuel pump is correctly co...

When diesel generator sets operate in high-altitude regions, their performance is significantly affected by environmental characteristics such as thin air, reduced atmospheric pressure, and large temperature variations. To adapt to these special conditions, comprehensive adjustments are required in design, configuration, maintenance, and operation. The specific adaptation measures and their principles are as follows: 1. Diesel generator intake system optimization: Compensating for thin air Turbocharging technology: At high altitudes, the decrease in air density leads to insufficient intake air and incomplete combustion. Turbochargers compress the intake air, increasing its density and ensuring the engine receives adequate oxygen, partially offsetting the power loss associated with rising altitude. For example, power decreases by approximately 8%–12% for every 1,000 meters of altitude gain. Intercooler configuration: After turbocharging, the air temperature rises, causing it to expand a...

As a universal component, the diesel generator exhaust pipe plays a crucial role in discharging waste gas and smoke in many generator sets. A well-designed exhaust system ensures that the waste gas and smoke generated during the operation of the generator set are effectively discharged outdoors, thereby minimizing impact on the surrounding environment and the work and life of residents. The design of a generator set exhaust system must comprehensively consider factors such as exhaust efficiency, safety, environmental protection, and equipment lifespan. Main components of the diesel generator exhaust system 1. Exhaust Pipe Material: Typically made of carbon steel or stainless steel, requiring high temperature and corrosion resistance. Structure: Includes straight pipes, elbows, tees, etc., requiring a rational layout to minimize resistance.

The radiator of a diesel generator is an important component of the generator set, and its main function is to remove the heat generated by the diesel generator through heat dissipation, maintaining the normal operating temperature of the generator. A heat sink is usually composed of heat dissipation pipes, fins, and fans. The working principle of a diesel generator radiator is to use coolant (usually water) to circulate in the heat dissipation pipe, transfer heat to the air through the heat dissipation fins, and exhaust the hot air through the fan. When a diesel generator is working, its engine will generate a large amount of heat. If it cannot dissipate heat in a timely manner, it will cause the generator to overheat and affect its normal operation. Therefore, the performance of the radiator directly affects the efficiency and reliability of the diesel generator.  During the operation of a silent diesel generator set, the coolant in the heat dissipation tank is usually very hot...

1. Precautions when starting Cummins diesel engine generator  (1) Before starting Cummins diesel engine generator, the starting system circuit and the charging condition of the battery must be checked first. When starting, check whether the battery terminal and battery clip are secure. (2) When starting a diesel engine, if one start cannot achieve the starting purpose, the interval between the second start and the first start should not be less than 2 minutes. (3) Quality requirements for starters, batteries, and battery cables. Each start time is not allowed to exceed 10 seconds. If diesel generator set is started, the hand should be quickly separated from the start button to prevent the failure of the swing wheel and flywheel after the diesel generator set is started. (4) When the diesel generator set fails to start for several consecutive times, the fault that caused the inability to start should be eliminated before starting. 2. Precautions for using chargers of C...

 According to the regulations of the power system, the main safety protection and requirements for the abnormal operation and possible faults of synchronous generators are as follows: Overload and short circuit protection of generators The protection of generator should use a circuit breaker that can simultaneously disconnect all insulation poles for overload and short circuit protection, and its overload protection should be compatible with the thermal capacity of generator. And the following requirements should be met: (1) When the overload is between 10% and 50%, the circuit breaker with a delay of less than 2mn should break. It is recommended to set it at 125% to 135% of the rated current of generator, with a delay of 15 to 30 seconds for the circuit breaker to break. (2) If the overload (current) is greater than 50% but less than the steady-state short-circuit current of generator, the circuit breaker should break after a short delay required by the system selective prot...

In today's world, diesel generators have become a popular solution for backup power supply. To ensure the normal working of diesel generator sets , reduce the unnecessary maintenance and increase the serviceability rate, it's necessary to conduct inspection on generator sets. Here are five inspection standards on construction sites:  We have to make sure the output voltage of diesel generators used on construction sites meets the voltage level requirements of the external power supply, under the condition that the whole thing works. This measure not only ensures the normal operation of equipment on construction sites, but also effectively reduces the risk of electrical equipment damage and improves the efficiency of construction on site. Meanwhile, reasonably adjusting the output voltage of the generator is also beneficial for saving energy resources, reducing its energy consumption, and meeting the requirements of sustainable development. Therefore, in construction sites, we ...

Diesel generators are renowned for their reliability, durability, fuel efficiency and low maintenance. They are commonly used as emergency backup power supply or used in remote areas where the power grid is unavailable. When buying a diesel generator set for an application in a noise-sensitive location, you need a noise-reducing solution. Silent type generators often come either containerized or with a canopy.
