近年来 ,在石油矿场用泥浆泵的基础上开发了各种类型的油隔离泵和隔膜泵。比如用于输送高磨砺料浆溶液 ,其特点是腐蚀性强 ,固体含量大 ,其矿浆温度为 90～ 1 0 0℃、苛性碱浓度为 2 70～ 2 90 g/ L、固体含量为 2 6 0～ 30 0 g/ L、固体颗粒粒径为 + 6 5# 筛≯ 5% ,+ 1 6 0 # In recent years, various types of oil-isolating and diaphragm pumps have been developed on the basis of mud pumps for oil mines. For example, it is used to convey highly abrasive slurries, which are characterized by strong corrosiveness and large solid content. The slurry temperature is 90 ~ 100 ℃, the caustic concentration is 2 70 ~ 2 90 g / L and the solid content is 2 6 0 ~ 30 0 g / L, the particle size of solid particles is + 6 5 # screen sieve 5%, + 1 60 #
