 Product Description

移动式泡沫罐概述:
PHYM系列贮罐隔膜式比例混合装置(以下简称混合装置),具有性能稳定,适用流量压力范围广、压力损失低等特点,它可与PFS型高倍数泡沫发生器、PZ型中倍数泡沫产生器、PC型低倍数泡沫产生器、PQ型空气泡沫枪或PP型泡沫炮组成各种高、中、低倍数泡沫灭火系统,该系统已在石油化工企业、港口码头、油库、机场等场所的消防系统中均得到广泛应用。

一、组成及分类:
该混合装置是泡沫灭火系统中泡沫混合液的供给源,它一般由泡沫液贮罐、PHY型压力式比例混合器、进水管路、出液管路、排气管路、排水管路、排液管路、液位显示管及压力表和安全阀等组成,各管路上均配备有相应的阀门。
混合装置按安装形式可分为卧式和立式两种,按内部结构又可分为整体型、分隔型、隔膜型三种。

二、工作原理
当压力水流经混合器管路时,有部分水经进水管进入贮罐内,大部分水沿混合管路进入比例混合器的喷嘴向扩散管喷出。进入喷嘴时,口径缩小,流速增大,由于射流质点的横向紊动扩散作用,在喷嘴出口与扩散管之间形成低压混合室,进入贮罐内的水将胶囊内贮存的泡沫液从出液管压出,经孔板进入比例混合器的低压混合室与流经比例混合器喷嘴的大股压力水流汇合形成3%或6%的泡沫混合液,该泡沫混合液被输送至泡沫产生设备,产生空气泡沫用于扑救甲、乙、丙类液体火灾及木材、纸张、纺织品等固体火灾。

三、维护与注意事项
1. 每月至少进行一次外观检查,各阀门及各连接处应无渗漏,各阀门平常应处于关闭状态。
2. 每年至少进行一次泡沫液液位检查和胶囊泄漏检查。若发现胶囊有损坏时,应及时通知本公司进行处理。
3. 每次使用后,必须用清水冲洗管道。
4. 装置长时间放置后表面若出现掉漆或锈迹时应进行补漆防腐处理。
5. 混合装置应避免阳光直射,并贮藏在温度变化小的场所,防止空气直接接触。
6. 泡沫液贮藏时间较长时,应抽样检验,如失效变质则应及时调换。
7. 在备用状态时,贮罐内一定要充满泡沫液。
8. 所选用的泡沫液的混合比应与混合装置中比例混合器的混合比相同。
9. 应保持罐内清洁,泡沫液不得与油类、水及不同牌号的泡沫液混用,泡沫液型号不能用错。
10. 不得在超出工作压力范围的情况下使用本混合装置。
11. 有关泡沫液的有效期,请向泡沫液供应商咨询,如失效变质应及时调换。
