GTAKE控制器成功应用于巴黎及纽约环卫车

      联合国《2019年碳排放差距报告》称,为实现气候目标,未来十年全球每年需减排2.7%。

      报告指出,在过去10年间,温室气体排放每年增长1.5%,其中2018年温室气体排放创下553亿吨“二氧化碳当量”的新高。温室气体的排放很大一部分来自于车辆尾气,其中各类重型卡车尾气的排放约占四分之一。

      环卫车作为一种常见车型,在很多垃圾清理站都可见它们的身影,协助我们清理运输生活垃圾,让我们的居住环境保持干净整洁。环卫车在等待装载和卸载时,需要发动机一直处于运转状态,以带动车上的负载,诸如上装系统、车载空调、气泵等。发动机长时间怠速运转不仅产生恼人的噪音,还会产生更多的温室气体,既不经济也不环保。

 

 

如何解决?

随着混合动力技术在乘用车上的广泛成熟应用,也为解决该问题指明了方向。

 

      加拿大E公司经过多年的系统性研究,反复测试、论证,现已为环卫车等各类专用重型卡车创新性地设计出优异的混动系统解决方案。

      该系统利用超级电容的大容量、可多次充放电特性,搭配关键的自动起停控制技术和远程数据监控和管理系统,高效地回收重卡制动时所产生的能量,有效地管理和减少了发动机的运行时间、燃油消耗以及尾气排放,已成功应用于巴黎和纽约等城市的环卫车。使用该系统后的车辆平均减少了26%以上的温室气体排放,得到市环卫局的高度认可,同时为环卫公司带来了显著的节油经济效益。

 

方案优势

GTAKE深度参与了该系统的研发匹配和测试。GTAKE技术团队凭借自身多年的技术积累,对系统进行反复分析、研判、现场测试及改进,帮助该系统实现节能目标效果,同时满足系统快速起停响应、电机平滑控制、极低的系统噪声输出,以及全方位的系统保护等要求。 

 

      该套重卡的混动系统除了可以应用于重型环卫卡车外,还能广泛应用于码头拖车、混凝土搅拌车、斗车等各类专用卡车,在重卡的节能减排上发挥巨大效用。GTAKE各类低压驱动产品、新能源汽车控制器、模拟电池和四象限驱动系统均已广泛应用在各节能减排、自动化及生产效率提升领域。

      让我们共同守护碧海蓝天、生命家园。

Agricultural irrigation is significant for the agriculture development in Egypt as most of the lands are quite sandy and the rainfall is extremely low. The solar powered irrigation systems using GTAKE solar pump drives SLR01A are helping farmers in Egypt to save the cost of energy, have minimal environmental impact, and produce no noise and pollution.

To meet the increasing food demand for the rapidly growing population in Egypt, lands in the western desert and other desert areas were reclaimed for agriculture business. Very high evapotranspiration and sandy soils require frequent water supply to ensure that the water will not leach towards deeper soil layers where it will be unreachable for the crops. Irrigation agriculture hence becomes essential in Egypt, explains Mr. Joseph, the CEO of SOTE. Usually these areas are far from grid power supply and conventionally resort to diesel generator to pump the water. Taking into account the costs of transportation of diesel, maintenance and overhauling of generators, using diesel is no longer economically feasible or affordable for those farmers. Also high CO2 emissions, excessive noise, immense diesel spilling into the soil and potential risk of long-distance transportation of diesel to the farms are the ecological downsides of water pump systems powered by diesel generator. This makes the use of alternative energy sources, particularly the green energy sources, vital to the development of Egypt’s agricultural sector.

Compared with diesel generator pumps, the solar pumps are far more environmentally friendly, with a longer lifetime and lower maintenance costs. The irrigation system usually consists of four parts: PV cells, a solar pump drive, a motor and a pump. GTAKE solar pump drives support both AC power supply (from grid or diesel generator) and DC power supply (from PV cells or battery) and could automatically stop the pump at sunset and wake up the pump in the next morning when the sun radiation meets the energy threshold, which benefits the users from saving the time to turn off or turn on the system again when the irrigation should be maintained for a few days continuously.

“The biggest advantages are that GTAKE solar pump drives can start the pump earlier in the morning and stop the pump later at the sunset. Also the efficiency of its inbuilt MPPT (maximum power point tracking) proves to be higher than most of the other brands we have tested,” continues Mr. Joseph. “Besides, many other functions such as solar weak sleep, dry run protection, pump cleaning function, classified user modes, and flow calculation are quite useful for different applications.’’

GTAKE solar pump drives are now widely used in MENA regions and South America for agriculture irrigation, fish farming, wastewater treatment and municipal engineering. Some users are using GTAKE solar pump drives for swimming pools in Euro for the purpose of energy saving and environment protection. More and more other applications such as city parks, rockery waterfalls and fountains using GTAKE solar pump drives are exploited by our customers globally.
