建筑工地发电机: 承包商综合电力规划指南

建筑工地需要电力来为不同设备供电, 工具, 重型机械, 和安全系统. 许多建筑工地都位于偏远地区，没有任何电力供应. 在这种情况下, 选择一个合适的 建筑工地发电机 是必须的. 因此, 您将能够及时交付项目.

您正在处理一个小型项目还是一个复杂的项目? 无论哪种情况, 正确规划施工现场的电力需求将使您作为承包商受益匪浅. 您是否正在为如何选择合适的而烦恼? 在本指南中 HuaQuan, 您将学习如何选择合适的尺寸, 安装指南, 安全提示, 并推荐了基于构建的最佳实践 发电机.

为什么建筑工地需要特定的发电机

承包商在不同地点开展临时项目. 他们必须私下安排设施. 必须有一个特定的发电机来为整个区域供电. 涉及原因如下:

• 重型机械要求: 其中包括大型混凝土搅拌机, 推土机, 塔式起重机, 和焊接设备. 它们需要大量的电力，而普通发电机无法满足.
• 缺乏电网连接: 在最初的地下作业或在偏远地区进行的项目中, 没有连接到市电. 在这种情况下, 整个网站工作正常 24/7 在发电机的帮助下
• 可变功率需求: 为建筑工地制造的发电机应具有灵活的性能. 不同日期的用电负荷不同. 例如, 第一天, 发电机仅为少数设备和现场拖车提供动力. 第六天, 它将为大型暖通空调机组提供动力.
• 工业阻力: 基本的自制发电机在连续极限容量运行时会中断 12 每天的小时数. 为此目的, 您需要一台便携式行业专用发电机才能在多尘环境中最长地运行现场.

建筑工地发电机的具体要求

在评估项目的电源解决方案时, 考虑建筑行业必须具备的这些特征.

移动性 & 可移植性

作为承包商, 您的建筑工地可能会有所不同. 所以, 发电机应该能够轻松运输和移动. 如果您使用的发电机既复杂又笨重, 使用起重机将它们运输到不同楼层或不同地点. 例如, 您必须使用配备有牵引装置的拖车起重机或装有提升装置的滑移式发电机.

耐用性 & 基于天气的抵抗力

建筑工地充满污染物, 排放气体, 泥, 灰尘, 和碎片. 发电机应具有运行状态, 钢制保护外壳可保护内部发动机免受这些有害成分的影响.

燃油效率

对于正在运营的网站 10-12 小时/天, 燃料是消耗最多的必需品. 现代和先进的工业发电机采用燃油喷射优化系统和不同速度的发动机，以加快发电机的工作速度，从而在有限的时间内实现最大性能. 它将帮助承包商每年节省数十万美元.

噪声污染控制

当您在市区工作时, 医院周围, 或在住宅区, 如果您的噪音超过一定分贝，当局将对您提出指控. 您必须使用内置声音衰减器的发电机，以最大程度地减少噪音污染.

如何计算建筑工地的电力需求

您必须适当计算电力需求. 按照以下步骤完美计算.

列出所有设备 & 工具

您必须列出所有将直接或间接使用电力的设备和工具. 该列表包括以下内容:

• 大型起重机和复杂起重机
• 混凝土搅拌机和泵
• 工业焊接机
• 非永久性 灯塔
• 排水抽水作业
• 工地办公室拖车 (包括暖通空调, 电脑, 微波炉)
• 手持式/手动电动工具 (包括锯子, 演习, 研磨机)

跑步与启动瓦数

这是大多数承包商最常犯大错误的领域. The electrical-based motors require an extensive increase of power for a mere start up. Such types of motors are found in cranes, 泵, and saws. This “starting wattage” is usually 3-4 times more than that of “running wattage.” You must have a generator that can handle the extreme starting rise. 否则, the whole area will shut down.

同时使用规划

You must remember that all tools do not operate at one time. When you apply a diversity factor for a variety of tools, it will help you decide the generator size appropriately. Calculate the maximum amount of load from those equipment that can run at one time. 例如, assume from the site trailer, the crane, and one welding ring that are working simultaneously.

建筑工地发电机的最佳燃料类型

The correct fuel type has a large effect on your construction area’s transportation, operational costs, and environmental factors.

柴油相关发电机 (在承包商中最常见)

Diesel always dominates all fuel types.

• 优点: Long-life of generator’s engine, maximum fuel efficiency within a short time frame, and appropriate for complex loads. Also used at the construction places to handle bulldozers, cranes, and excavators.
• 局限性: Heavy duty-based machines, strict regulations for emitting gases, and powering issues during cold weather when heaters are not installed.

汽油发电机

Gasoline generators are applicable for mobile, light, and portable activities.

• 优点: Low costing when bought initially, easy to carry and move manually around the site, and easy to power on in extreme cold weather.
• 缺点: High risks of setting on fire, low fuel efficiency, and low life of engines when used extensively.

混合动力或电池供电系统

When emissions legal regulations become strict, battery-powered energy storage systems (BESS) connected with smaller engines are becoming famous.

• 优点: No noise pollution, zero gas emission, suitable for inside renovation operation, and comply with urban sites with strict noise limitations.
• Disadvantages: Highly-priced, limited running time before you plug in to the battery.

选择正确的尺寸 & 容量

Selecting the kilowatt ratings of generators needs balancing the financial budget with working requirements.

• Small Sites: These include the residential buildings and commercial renovations. The demands of portable generators range between 10-20 千瓦. It is appropriate for manual tools, small air compressors, and a non-permanent power pole.
• Medium Sites: These include the commercial-based retails and mid-rise projects. The demands range between 50-100 千瓦. This range is perfect for construction area trailers, hoists, and complex welding tasks.
• Large Projects (High-Rise, Infrastructure, Mining): These include the high-rise, gold and copper mining, and huge infrastructure projects. The demands range between 250kw-1MW+. It is appropriate for large cranes and huge dewatering tasks.

The Risk of Wet Stacking: If you run a diesel generator at just 30% of its capability, it will create 湿堆放. It refers to the unburnt fuel that is accumulating in the exhaust chimney of the generator. 因此, it will damage the engine and wastes the warranty of the generator.

环境的 & 施工现场注意事项

The working of a generator depends on the environment of the actual site.

• Outdoor Working: You must put a generator a little above the ground level. You can use a concrete-made pad for this purpose. It will avoid your generator to restrict the air passage underneath and get dirty with mud.
• Dust and Debris: The environments with high-performing activities demand complex and multiple-leveled air ventilation systems. 因此, they can protect their engine from choking.
• Temperature Extreme Ranges: In the coldest temperatures, install the coolant heaters and particular winter-based diesel. 另一方面, in the extreme hot temperatures, you must set up a huge-sized radiator. It will protect the walls and prevent heat shocks.
• Terrain Difficulties: If your area has a slope, remember that the engines might not take up the fuel and show wrong standard readings.

安装 & 设置最佳可行实践

When you set up the generator appropriately, it helps you avoid lethal incidents and tools destruction.

• Appropriate Placement: You should place the generator minimum 20 ft far from the primary site. It will decrease the noise pollution for workers as well as the people around. 而且, it will help avoid toxic pollutants exposure as these will be released in a distant place.
• Wire Management: You must use high-capacity, durable, and protected wires, 例如, SOOW. 然后, protect these cables with resistant covers to prevent firing and explosion.
• Grounding Needs: OSHA incorporates grounding efficiently. When you are buying a 便携式发电机, also purchase an optimized copper rod to prevent accidents through electric shocks.
• 燃料储存: Store excessive fuel in proper tanks. 然后, place these tanks in secondary containers to prevent wasting in case of spilling. You should store them away from the generator’s chimneys.

施工现场相关发电机的安全指南

作为承包商, safety of workers and residents should be the first priority.

消防安全

You must place generators far from the burning materials and sites. 加, you should install fire alarms and extinguishers at the construction area. 还, keep them updated and maintained.

电气危险

You must prioritize professionals, such as electricians and electrical engineers for handling electrical work. 还, avoid loading the circuits with excessive power.

排气通风

Generators release dangerous gases, including carbon monoxide. That’s why you must place the generators in airy and highly ventilated places.

人才培养

The workers should get training related to all emergency situations and safety hazards.

维护 & 操作建议做法

If you follow a proper plan for maintaining the generators, they will prove cost-effective.

Following are some best tips you can adopt:

• Detailed checking everyday by a professional
• Inspecting oil levels as well as the quantity of the coolant
• Evaluating fuel quality
• Deep cleaning of air vents and filters
• Regular servicing of generators

If you adopt these measures, you will be able to increase the life of the machinery.

要避免的常见错误

• Selecting a generator by just considering its price
• Overlooking the power requirements of generators
• Placing the generators near construction sites at inappropriate places
• Not following the regular plan of 维护
• No backup strategy in case the generator disrupts the power

If you do not make these basic mistakes, you will be able to deliver high-performance results.

成本核算反思

The total budget includes the pricing of multiple things, apart from just including purchases.

购买或租赁

Those projects that complete within a short time period must prefer renting tools instead of investing a large amount of money on them.

燃油费

Extensive working hours during the whole day require a large amount of fuel that definitely costs a huge financial burden.

定期维护费用

Timely maintenance of generators demand relative expenses of professional repairers and repairing tools.

交通费用

Transferring generators from one site to another requires loaders. These require rental and other logistical costs.

最后说明

Selecting the appropriate 建筑工地发电机 that suits the requirements of your construction area is mandatory. It forms the basis of your project as it decides the timely delivery and successful completion of your project.

The accurate choice depends on the initial assessment of powering requirements of all tools and equipment being run at a site. It will help you choose between a diesel, 气体, or a hybrid system.
