鲁恩及其电动消防泵。
法国鲁恩（Rouen）的古城有一个电动消防泵，该泵已在先前数量的火和水中进行了简要描述。给出了更全面的描述。该泵是离心的（Thiron＆Lou的系统），并具有八马力的电动机，通常每分钟2,000转。该电动机被厚的覆盖物防止，以防止水的任何渗透，并通过其连续的525伏特施加。上面是两个梭芯，其中之一是接收电流的电线。这条线的末端是如此暴露，以至于允许用悬挂在头顶的手推车或电灯线悬挂的箍进行连接。返回线在另一根梭芯上缠绕。该电线具有其自由端与铸铁块连接，可以固定在地表道路的一条轨道上。覆盖物下方是一个隔间，其中包含两个电流断路器，一个电路封闭器和一个换向器。在启动泵时，两条电线连接到了提供能量的线。 the circuit is then closed, and started running slowly with the rheostatic guide, and, on the latter being fastened to the circuit-breaker, the motor, in about one minute, runs normally. The bobbins, on which are wound the conductors, can receive 656.167 feet of insulated wire. This and the same number of feet of hose on the reel and the 114.83 feet to which the stream of water can lie thrown and a distance of 1,427.16 feet can he covered. The water (as already said) is thrown 114.83 feet by an 0.7-inch nozzle at the rate of 92,46 gallons per minute. This fire pump, which can be carried on a handcart or a small two-wheeled, onehorsewagon, weighs, with accessories and two men on the seat, only 2.292.78 pounds. The length of the motor and pump is only 39.37 inches, and its width and height. 19.685 inches each. Behind the machine is a reel with a capacity of 984.25 feet of hose, two lances, a ladder, with hooks, an axe, a hydrant key, a nozzle, etc. the reel, with all this equipment, weighing only 727,519 pounds.
这款电动消防泵的起源是由于一位德国工程师构想的，他们想到了用沙子构建电动泵来清洁建筑物墙等的想法。Rouen Fire Company的Robert Lefebvre上尉将这个想法转向了自己的优势，并建造了这款电动泵（其中唯一的一种 - 扔水，而不是沙子。
