SP型砂泵是一种离心式砂泵。多年的生产实践证明,它存在着不少缺点。例如,它的制水机构结构复杂(共41件),制水作用很差,滚动轴承寿命短(2～4个月),事故多,维修工作量大,消耗高。因此,已被我国自行设计的PS型砂泵所代替。 我厂原有11台SP型砂泵,我们针对它存在的主要缺点,进行了改造以进一步发挥它们的作用。 SP sand pump is a centrifugal sand pump. Years of production practice has proved that it has many shortcomings. For example, its water-making mechanism has a complicated structure (a total of 41), poor water-making effect, short rolling bearing life (2 to 4 months), many accidents, heavy maintenance work and high consumption. Therefore, it has been designed by our own PS sand pump instead. Our original 11 SP sand pump, we aimed at its main shortcomings, have been transformed to further play their role.
