【摘要】 利用20 cm不锈钢高压锅作为集气室,在锅的两边上、下分别打一个进出水孔,用15 mm不锈钢管道件连接,把进水口制作成高于锅内液面,出水口与锅内液面为同一水平面,形成一高一低,一小一大两个相对稳定的动态水平液面,在进水管中引入气泵输出气体,使集气室内进水同时进行自动连续鼓泡,把水中气体脱出,在输气管中接入玻璃转子流量计控制气体流量,进行恒流鼓泡。并应用于小流量冷水井气氡观测,效果显著。更多还原

【Abstract】 A 20 cm stainless steel pressure cooker is used as gas collecting chamber,in a pot on either side of the upper and lower,respectively,in and out of the hole,use 15 mm stainless steel pipe connection,the water inlet into liquid level in the above,the outlet and the pot liquid level for the same horizontal plane,form held high,a small and a big,two relatively stable level of dynamic liquid level in the inlet pipe of pump output gas,the gas collecting chamber for automatic continuous bubbling at the same time,the water to the water gas out,access to glass rotor flowmeter in the pipeline gas flow control,constant current bubbling. And applied to the small flow of cold water Wells gas radon observation,the effect is remarkable.更多还原
