近十多年来，随着我国建设规模的扩大和城市建设的飞速发展，破的泵送量飞速增加，其中以检拖式泵泵送的硅量增加尤为突出，据我公司的统计资料表明，1996ap拖式泵泵送的检总量已达2600万m’。检拖式泵泵送的硅布料过去是通过改变输送管长度从而改变出料口位置加人工展开的方式 Over the past decade or so, with the expansion of China’s construction scale and the rapid development of urban construction, the volume of broken pumps has increased rapidly. Among them, the pumping of silicon by trailing pump has been particularly prominent. According to the statistics of our company , 1996ap trailing pump pumping seized total reached 26 million m ’. Trailing pump pumped silicon cloth in the past by changing the length of the transfer tube to change the position of the discharge port manually expand the way
