Correct Installation Method Of Diesel Generator Set

Oct. 21, 2021

Diesel generator set is a kind of power generation equipment with diesel as the main fuel. The diesel engine is used as the motive power to drive the generator to generate electricity, and the kinetic energy is converted into electrical energy and thermal energy. The complete unit is mainly composed of the unit base, diesel engine, base fuel tank, generator, controller, radiator, silent box and other components. It has a wide range of uses in industrial and agricultural production, national defense, science and technology and daily life. This article, Jiangsu Starlight Electricity Equipments Co.,Ltd. will introduce you to the correct installation method of diesel generator set.


1. Basic acceptance: Before installing the diesel generator set body, a comprehensive inspection of the equipment foundation should be carried out according to the design drawings, product samples or the actual diesel generator set body, and whether it meets the installation requirements.


2. Equipment unpacking inspection: According to the packing list, check the host, accessories, special tools, spare parts and accompanying technical documents, etc., appearance inspection, with nameplate. The body has no missing parts, the coating is complete, whether the equipment meets the design requirements, etc.


3. Unit installation: Hoist the unit as a whole with lifting equipment, install the random shock absorber under the unit, and place the unit on the basis of the completion of the construction of the diesel generator unit.


4. Fuel system installation: The fuel supply system is generally composed of oil storage tanks, daily fuel tanks, oil pumps, solenoid valves, and connecting pipes. There are liquid level display and float switch on the oil tank for daily use. The installation requirements of the oil pump system refer to the installation specifications of the water system equipment.

5. Installation of the smoke exhaust system: The smoke exhaust system is generally composed of a smoke exhaust pipe, a smoke exhaust muffler and various connectors. The smoke exhaust pipe is wrapped with a layer of insulation material, and the connection between the motor unit and the smoke exhaust pipe is usually corrugated. The weight of all the exhaust pipes is not allowed to press on the bellows. The bellows should be kept in a free state. The installation of the ventilation system, install the air inlet louver or the air valve with bolts.


6. Installation of the exhaust system: According to the location and size of the exhaust outlet of the unit, install the exhaust fan, the intermediate transition body, the soft connection, and the exhaust outlet.


7. Installation of the cooling water system: Check the inlet and outlet of the heat exchanger of the water-cooled diesel generator set, and the pressure direction is consistent with the pressure of the pressurized cooling water source, connect the inlet and outlet pipes. The connection between the cooling water inlet and outlet pipes and the main body of the generator set should be isolated by hoses.


8. Battery charging inspection: According to the requirements of the product technical documents, enter the battery for charging and charging, and the maintenance-free battery does not need to add additional electrolyte.


9. No-load test run of diesel engine: The diesel engine of the diesel generator set needs to be run without load. After inspection, there is no oil or water leakage, and the machine runs smoothly. The speed is automatic or manual to meet the requirements. The diesel engine is qualified for the no-load test run, and the generator no-load test is performed.


10. Generator static test and random distribution panel control cabinet wiring inspection: Complete the test and inspection of the stator circuit, rotor circuit, excitation circuit and other items of the diesel generator set according to the attached table in the main control project, and make a record. It is best to have the manufacturer present or complete it directly.


11. No-load test operation of the generator set: Disconnect the circuit breaker or ATS on the load side of the diesel generator set, turn the control switch of the unit control panel to the "manual" position, and press the start button, check whether the unit voltage, battery voltage, and frequency are in within the error range, otherwise make appropriate adjustments, check the oil pressure gauge. All the above is normal, and then the normal stop and emergency stop test can be completed.


12. Generator set on-load test: After the generator set has passed the no-load operation, cut off the load "mains" power supply, press the "genset load" button, and perform the false load (water resistance) test after passing the test, and then the generator set to the load power supply, check whether the generator is running stably, whether the frequency, voltage, current, and power maintain the rated value.


13. Self-starting time test: When the two mains power sources are interrupted at the same time, the standby generator will be automatically put into operation, and it will be put into full load state within the time required by the design. When the mains power supply is restored, all the backup power loads are automatically returned to the mains power supply system, and the generator set automatically exits operation.


The above is an introduction to the correct installation of diesel generator sets organized by Jiangsu Starlight Electricity Equipments Co.,Ltd..


In addition to the installation of the generator, the location of the engine room is also very important. Jiangsu Starlight Electricity Equipments Co.,Ltd. recommends that the location of the generator room should be as far away from residential areas as possible to reduce noise and emissions Residents’ influence.


Jiangsu Starlight Electricity Equipments Co.,Ltd. is one of the earliest manufacturers of generators and diesel generator sets in China. The company was established in 1974 and the company occupies an area. With an area of 86,000 square meters and a building area of 45,000 square meters, it has 64 sales and service departments across the country to provide users with one-stop service of design, supply, debugging and maintenance at any time.
