排灌站安装的水泵管路,由于风吹、日晒、雨淋等原因,总免不了要生锈、脱皮;有的钢管因露天存放,使用前就已锈蚀。因此,做好水泵管路的防锈、除锈工作,是保证其使用寿命很重要的一环。具体防锈措施:有的社队采用沥青涂刷管路表面、有的采用调合漆,实际上这两种办法都不太好。沥青性脆,附着力差,粘度大,不易涂刷,易脱落,成本较高;调合漆价格也较高,用的少。我们试验用煤油稀释沥青,涂刷钢管防锈,效果较好。煤油稀释的沥青,附看力强,易涂刷,不脱落,成本低,用工少。煤油沥青防锈的具体作法:先将沥青加热熔化,按1∶(0.25～0.3)的比例(即一斤煤油配2.5～3.0两沥
Pumping lines installed at irrigation and drainage stations will always have to be rusty and peeling due to wind, sun and rain. Some steel pipes have been corroded before use because they are stored in the open air. Therefore, good pump pipe rust, rust work is to ensure that the service life is an important part. Specific anti-rust measures: Some commune teams use asphalt painted pipe surface, and some use of blending paint, in fact, these two methods are not very good. Asphalt brittle, poor adhesion, viscosity, easy to brush, easy to fall off, high cost; blending paint prices are higher, with less. We test the use of kerosene diluted asphalt, brushing steel rust, the better. Kerosene diluted asphalt, with strong look, easy to brush, do not fall off, low cost, less labor. Kerosene tar concrete anti-rust practices: first asphalt melted by heating, according to the ratio of 1 (0.25 ~ 0.3) (that is, a pound of kerosene with 2.5 to 3.0 Liang Li
