Description
技术领域Technical field
本发明涉及泵技术领域,具体为一种滑板式泡沫液泵及具有该泵的消防泡沫液系统。The present invention relates to the technical field of pumps, specifically a slide-type foam liquid pump and a fire-fighting foam liquid system having the pump.
背景技术Background technique
因火灾而引起的生命和财产的损失是巨大的,据消防部门统计,2006年1至8月份,全国共发生火灾159901起,死亡1052人,受伤995人,直接财产损失51334万元,而且,亡人火灾多集中在住宅,死亡人员六成以上为弱势群体,亡人火灾和重特大火灾多发生在夜间,22时至凌晨6时是亡人火灾和重特大火灾的多发时段,引起火灾的原因依次是:因生活用火不慎、违反电气安装使用规定、吸烟、玩火、违章操作、自燃和雷击。消防部门同时提醒。火灾发生后3分钟是灭火的最佳时机。综合上述调查,可知,要在三分钟内进行灭火,势必要在火场附近有可供随时使用的小型便携式消防泵,才能达到灭火的要求。现有的消防泵多采用水力驱动消防罗茨泵,现有的水力驱动消防罗茨泵体积较大,重量较大,不利于消防救护,同时在使用过程中容易因水质中的细砂粒等产生故障,维修起来较为麻烦;此外传统的机械泵入式泡沫比例混合装置,虽然可以扑灭火源,但在设备上使用的是柱塞泵,该类柱塞泵一般为多缸型式,一是占用的空间大;二是噪音大;三是柱塞泵的工作是靠曲轴、连杆、活塞工作,需求的动力大,也就是消耗消防水压力大;四是柱塞泵比滑板式泡沫液泵结构复杂,易于出现故障,维修也没有滑板式泡沫液泵简单。The loss of life and property caused by fires is huge. According to fire department statistics, from January to August 2006, a total of 159,901 fires occurred across the country, with 1,052 deaths, 995 injuries, and direct property losses of 513.34 million yuan. Moreover, Most of the fatal fires are concentrated in residences, and more than 60% of the fatalities are vulnerable groups. Most of the fatal fires and serious fires occur at night. From 22:00 to 6 am is the time period when fatal fires and serious fires occur frequently. The number of fires caused by The reasons are: careless use of fire in daily life, violation of electrical installation and use regulations, smoking, playing with fire, illegal operation, spontaneous combustion and lightning strikes. The fire department also reminded. 3 minutes after a fire breaks out is the best time to put out the fire. Based on the above investigation, it can be seen that in order to extinguish the fire within three minutes, it is necessary to have a small portable fire pump that can be used at any time near the fire scene to meet the fire extinguishing requirements. Existing fire pumps mostly use hydraulic-driven fire-fighting roots pumps. The existing water-driven fire-fighting roots pumps are larger in size and weight, which is not conducive to fire rescue. At the same time, during use, they are easily caused by fine sand in the water quality, etc. Failure, maintenance is more troublesome; in addition, although the traditional mechanical pump-in foam proportioning mixing device can extinguish the fire source, it uses a plunger pump on the equipment. This type of plunger pump is generally a multi-cylinder type. First, it occupies The space is large; the second is the noise; the third is that the plunger pump works on the crankshaft, connecting rod, and piston, which requires a lot of power, which means it consumes a lot of fire water pressure; the fourth is that the plunger pump is smaller than the slide-type foam liquid pump. The structure is complex and prone to failure, and maintenance is not as simple as the slide-type foam liquid pump.

本滑板式水力马达采用专门制作的泵体,减少水的流量阻力及液体的吸进阻力;增加进出水通道面积可让进出水流量变多,进而增加水的进出速度。由于结构更加紧凑、精炼,使用材料体积更小更轻。对出口阀门、出口管道没有特殊要求;安装、使用、维修方便,驱动装置带动泵盖上的转子转动,转子转动时,泵盖中的滑片亦随之做往复滑动,通过泵盖中的进水口和出水口,实现对消防用水的吸入和排出,可极大的改善了现有的水力驱动消防泵使用效能不高,增加了可靠性。This slide-type hydraulic motor adopts a specially made pump body to reduce the water flow resistance and liquid suction resistance; increasing the area of the water inlet and outlet passages can increase the inlet and outlet water flow, thus increasing the water inlet and outlet speed. Due to the more compact and refined structure, the materials used are smaller and lighter. There are no special requirements for outlet valves and outlet pipes; installation, use, and maintenance are easy. The driving device drives the rotor on the pump cover to rotate.

本系统中滑板式水力马达靠消防水驱动,泡沫液滑片泵其输出压力高于消防水压,可以使泡沫液通过比例混合器顺利的注入消防管道中,该设备配备的比例混合器,可以喷出的泡沫液和消防水均匀混合,从而通过泡沫产生装置,产生泡沫用于火灾现场。此外,在泡沫管线上配置一个单向流动装置、安全卸放装置等,可以防止消防水导流至泡沫原液储罐中;因配置有安全卸放装置,也不至于出现超压的现象,因火灾往往伴随停电,本设备可以再无电源情况下,利用消防水流体压力进行救火。In this system, the slide-type hydraulic motor is driven by fire water. The output pressure of the foam liquid sliding vane pump is higher than the fire water pressure, which allows the foam liquid to be smoothly injected into the fire pipe through the proportional mixer. The equipment is equipped with a proportional mixer that can The sprayed foam liquid and fire water are evenly mixed, and then pass through the foam generating device to generate foam for use at the fire scene. In addition, configuring a one-way flow device, safety discharge device, etc. on the foam pipeline can prevent fire water from being diverted into the foam raw liquid storage tank; because it is equipped with a safety discharge device, overpressure will not occur, so Fires are often accompanied by power outages. This equipment can use fire water fluid pressure to put out fires even when there is no power supply.
