Recently, in response to scenarios where diesel generator sets need to be installed on the second floor in some projects, to ensure the quality of equipment installation, operational safety, and the stability of the surrounding environment, the technical department of the company has summarized the core precautions based on years of engineering practice experience, providing professional technical guidance for the implementation of relevant projects.
As important emergency power supply equipment, the installation environment and construction specifications of diesel generator sets directly affect operational reliability. Compared with installation on the ground floor, installation on the second floor is more affected by factors such as load-bearing conditions, spatial layout, vibration transmission, and smoke exhaust and heat dissipation. Strict control is required throughout the entire process from pre-preparation to post-acceptance.
I. Pre-preparation: Laying a Solid Foundation for Installation
1. Special Inspection of Floor Load-bearing Capacity
The core premise of installation on the second floor is to ensure that the floor load-bearing capacity meets the equipment requirements. When a diesel generator set is in operation, it includes its own weight, fuel weight, and operational vibration load. It is necessary to jointly conduct a load-bearing test on the floor of the installation area with the architectural design unit in advance. Focus on verifying the rated load-bearing data of the floor, requiring the load-bearing capacity of the installation surface to be not less than 1.2 times the total weight of the equipment (including the unit, fuel tank, foundation, etc.). If necessary, reinforcement treatment of the floor is required, such as adding load-bearing beams and laying load-bearing steel plates, to eliminate structural safety hazards.
2. Rational Planning of Installation Space
Rationally plan the installation position of the unit in combination with the spatial layout characteristics of the second floor. It is necessary to ensure the safe distance between the unit and the wall and other equipment: the distance from the left side to the wall is not less than 1.5 meters, the distance from the right side and the rear end to the wall is not less than 0.8 meters, and the distance from the front operation surface to the wall is not less than 1.2 meters, which is convenient for equipment maintenance, operation and heat dissipation. At the same time, reserve equipment hoisting channels to ensure that the unit can be smoothly transported from the first floor to the installation area on the second floor. The width, height of the channel and the load-bearing capacity of the stairs must match the size and weight of the unit.
3. Equipment Selection Adapted to Scenarios
Prioritize the selection of compact and lightweight unit models to reduce the pressure on the floor load-bearing capacity on the premise of meeting the power supply requirements. At the same time, considering that the ventilation conditions in the second-floor space may be limited, it is necessary to select units with excellent heat dissipation performance or plan additional heat dissipation devices in advance; for vibration transmission problems, low-vibration units can be preferred, and supporting high-efficiency vibration reduction accessories can be equipped.
II. Construction Process: Strict Control of Key Links
1. Installation of Vibration and Noise Reduction System
The vibration generated by the operation of the diesel generator set is likely to be transmitted to the lower floor through the floor, causing noise pollution and structural damage. During installation, professional vibration reduction devices, such as rubber vibration isolation pads and spring vibration isolators, need to be added between the unit base and the floor. The selection of vibration isolators must match the unit weight and vibration frequency, and they should be evenly distributed at the supporting points of the base. At the same time, flexible connections should be adopted between the unit and the smoke exhaust pipe, oil pipe, cable and other connecting parts to reduce vibration transmission.
2. Standard Layout of Smoke Exhaust System
The installation of the smoke exhaust system directly affects the equipment operation efficiency and environmental safety. For installation on the second floor, it is necessary to rationally plan the direction of the smoke exhaust pipe, minimize the pipe length, and reduce the number of elbows (no more than 3 elbows) to avoid excessive exhaust resistance caused by too long pipes. The smoke exhaust pipe should be made of high-temperature resistant and corrosion-resistant materials, and the outer layer should be wrapped with thermal insulation cotton to prevent high-temperature scalds and heat diffusion from affecting the surrounding environment. The pipe outlet should extend outdoors and be higher than the roof or away from doors and windows to avoid smoke backflow into the room or affecting surrounding residents.
3. Guarantee of Fuel and Cooling Systems
The fuel tank should be installed away from fire sources and heat sources. It is recommended to use explosion-proof fuel tanks, and a safe distance should be maintained between the fuel tank and the unit. The oil pipe connection should be firm and sealed to prevent fuel leakage. Special attention should be paid to the fixation of the fuel tank during installation on the second floor to avoid displacement of the fuel tank caused by unit vibration. For the cooling system, if an air-cooled unit is adopted, it is necessary to ensure good ventilation in the installation area; if a water-cooled unit is adopted, it is necessary to rationally arrange the cooling water pipeline to ensure unimpeded water flow, and take anti-freezing and anti-leakage measures.
4. Standard Layout of Electrical Circuits
The installation of electrical circuits must comply with electrical construction specifications. The selection of cables must match the unit power. The circuit layout must be protected by threading pipes to avoid mixing with other circuits. The connection between the unit and the distribution cabinet and control cabinet should be firm, and the terminal blocks should be compressed to prevent heat generation caused by poor contact. At the same time, install a reliable grounding system with a grounding resistance of not more than 4Ω to ensure the personal safety of operators.
III. Post-acceptance and Operation & Maintenance: Ensuring Long-term Stable Operation
1. Strict Control of Installation Acceptance
After the completion of equipment installation, professional and technical personnel should be organized to conduct a comprehensive acceptance. Focus on inspecting key links such as the effect of load-bearing reinforcement, the installation of vibration reduction system, the tightness of smoke exhaust pipes, the tightness of fuel and cooling systems, and the connection of electrical circuits. At the same time, conduct a trial operation test of the unit to check the unit's operation status, vibration, smoke exhaust effect, power supply stability, etc., to ensure that all indicators meet the specification requirements.
2. Regular Operation & Maintenance Guarantee
Establish and improve the operation and maintenance management system, and conduct regular inspections and maintenance of the unit. Focus on checking the aging of vibration reduction devices, the corrosion of smoke exhaust pipes, the leakage of fuel and cooling systems, and the insulation performance of electrical circuits, and promptly detect and deal with potential hazards. At the same time, regularly clean up debris in the installation area to maintain unimpeded ventilation and provide a good environment for unit operation.
The installation of diesel generator sets on the second floor is a systematic project that needs to take into account safety, efficiency and environmental requirements. The company will continue to rely on its professional technical team to provide customers with full-process services from pre-planning, equipment selection to construction and installation, and post-operation and maintenance, ensuring the smooth implementation of each project and the stable operation of equipment.
