磨粒侵蚀是除泥器和除砂器中锥套这一主要易损件产生磨损的基本形式。通过大量试验,研究了四种高分子材料发生磨粒侵蚀的基本规律,并得出了相应的回归方程(磨损方程)。 Abrasive grain erosion is the basic form of wearing of the main wearing parts of the desilter and desander. Through a large number of tests, the basic rules of abrasive erosion of four kinds of macromolecule materials were studied, and the corresponding regression equation (wear equation) was obtained.
