我们县1983年夏收时发生三起火灾,都是拖拉机打场引起的,这些拖拉机都装有灭火器(火星收集器)。因此,装了灭火器打场时仍然需要小心谨慎。为什么呢?因为: 1.有的灭火器本身质量有问题,焊接不牢,因开焊而漏气,或本来就没焊接严密。 2.灭火器安装不好,如灭火器与排气管连接法兰端面不平或损坏,垫片选择不当,螺栓松动等造成漏气。 3.灭火器保养、保管不善,技术状态恶化。如挤压变形后离心灭火性能变差;放炭螺钉锈蚀,灭火
Three fires occurred in our county in the summer of 1983 and were caused by tractor punches. All these tractors were equipped with fire extinguishers (Mars Collector). Therefore, the installation of fire extinguishers still need to be careful when playing. Why? Because: 1. Some fire extinguishers have their own quality problems, the welding is not strong, because of welding and leaks, or had no welding tight. 2. Fire extinguisher installation is not good, such as fire extinguishers and exhaust pipe connecting flange end uneven or damaged, improper choice of gasket, bolts and other loose caused by leakage. 3 fire extinguisher maintenance, poor care, technical conditions worsened. Such as extrusion deformation of centrifugal fire worse; put carbon screw rust, fire
