Diesel Generator Tech

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...

Dingbo Power trailer-mounted mobile double-suction split-case pumps feature a compact structure, stable operation, high flow rate, excellent efficiency, safety, reliability, long service life, and easy maintenance. They are widely applicable in agricultural, construction, water conservancy, environmental protection, and industrial fields. So, how should these mobile double-suction split-case pumps be used correctly? Let’s explore the steps below.  Steps for using the trailer-mounted mobile double-suction split-case pump   Step 1: Preparation before starting the pump unit Before using the double-suction split-case pump, connect the inlet and outlet pipes. Prior to starting, check whether the engine oil is sufficient, ensuring the oil level is between the Full and Add marks. Verify the coolant level, which should be about 5 centimeters below the cap. Then, check the fuel level and ensure the battery is adequately charged. Inspect whether all fast...

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...

Diesel generator sets are widely used in the market. For example, they are used for emergency power generation and serve as backup power sources for industries such as hospitals, banks, airports, hotels, and communications. Therefore, there is a growing demand for knowledge about diesel generator sets. A generator is a complex mechanical device, and to truly master the essential knowledge, in - depth research and understanding are required. However, there are many fallacies in the use of diesel generator sets. At first glance, they seem correct, but upon closer examination, they are not. The following is a detailed explanation by the editor of Guangxi Dingbo Power on the following two aspects: The first misconception: The lower the water temperature of the diesel engine, the better During the operation of a diesel engine, there are certain requirements for the water temperature. It's not true that a lower water temperature is better. In practical applications, some people tend to...
