Diesel Generator Tech

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. Insulation: High-temperature exhaust pipes require insulation layers to prevent heat loss and burn risks. 2. Muffler Function: Reduces exhaust noise...

Selecting the correct generator size is critical for ensuring the reliability, efficiency, and longevity of both your generator set and the equipment. If you are unsure what size generator you need, the process boils down to one key principle: understand the electrical demands of all the equipment you plan to run. Here is a simple guide to help you determine the perfect generator size for your application. Step 1: Calculate Your Total Power Requirement   The first and most crucial step is to create a comprehensive list of every device you intend to connect to the generator set. 1. Identify Each Device: List all equipment, from the largest machinery to the smallest tools or lighting systems. 2. Find the Power Rating: For each device, find its power rating, usually listed on a nameplate or in the user manual. This is typically given in Watts (W) or Kilowatts (kW). (1 kW = 1000W). 3. Calculate Total Running Wattage: Add up the running wattage of all d...

Diesel generator sets are widely used in various fields such as industry, agricultural breeding, medical care, military, and schools. For users, it is becoming increasingly important to understand the knowledge and application of diesel generators. Today, the editor will share two pieces of knowledge with you. One is the usage instructions for generator sets at different altitudes and temperatures, and the other is the functions of the generator coupling. The main components of a diesel generator set are the engine and the generator. Normally, we need an excellent diesel generator set to meet our power needs. Under different environmental temperatures and high - altitude conditions, what is the correct way to use it? The editor has summarized the following points for you: Environmental temperature and altitude The engine can operate under the following conditions without power adjustment: For an engine with a rotational speed of 1800 r/min, the altitude is below 1525 m (5000 ft) an...

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...
