Fire-fighting equipment for fire-fighting and rescue service vehicles-part 6 : hydraulic lifting equipment with single acting hydraulic rams 消防车和救援服务车用消防技术装备.第6部分:带单作用
Additionally, the solar garden in the lady shaw building is equipped with a photovoltaic panel accumulator and its hydraulic ram pump . 5 此外,大学还有用光伏版蓄电的邵逸夫夫人楼的太阳能花园,与及运用水力供水的水锤泵。
To harness these natural resources, the university uses a hydraulic ram to pump nullah water to storage sites for irrigation and flushing 有见及此,大学善用自然资源,不单以山水来灌溉花草和冲厕,就连泵水往储水缸的水泵,也是利用水力推动的。
Richard yem sync : under the action of the waves the hydraulic ram's blue unit, shown down here on my left, pumps high pressure fluid into these large accumulators richard同步解说:在波的作用下,液压油缸的蓝色单元,在我的左边,将高压液体泵入大型蓄电池。
hydraulic ram pumps are environmentally friendly and can be used for over 30 years with minimal maintenance . they have been widely used overseas and on the mainland 水锤泵以水力推动,不耗能源,洁净无污染,而且也甚少故障,可用上三十年,省却不少维修费用。

In doing so, each of these long sections articulates up and down and side to side, and the movement's resisted by hydraulic rams which convert that mechanical energy into electricity 在这个过程中,机器的两部分被上下和两边固定,波产生的机械能被液压油缸转化为电力。
Last year the estates management office installed a hydraulic ram pump photo 1 in the nullah near orchid lodge in chung chi college . the device transports water to the storage tank by making use of the kinetic energy of falling water 物业管理处去年在兰苑附近的溪涧安装了水锤泵(图一),善用了溪水下流的动能,把水输往储水缸待用。
Once the water reaches its maximum speed, the valve slams shut and pressure is built up in the pump . this pressure forces open a second valve linked to the delivery pipe . when nullah water falls past the hydraulic ram, its momentum will lift a tenth of the water to a storage tank located near the esther li building photo 2 泵内有活门,当溪水在流动中受阻,会产生比正常压力高十倍以上的瞬时水锤压力,此时,泵内的另一活门会打开,把十分之一的溪水抽往设于李慧珍附近的储水缸备用(图二)。
