60000系列单面带防尘盖的深沟球轴承,可防止污物从外面侵入轴承,主要应用在难以单独安装防尘装置的机件或结构中。我们据此特点在化工高速泵中采用该轴承,取得了较好的效果。 我厂的GWA-Ⅱ型苯加料泵是上海化工研究院研制的铝合金高速泵,该泵体积小巧,结构紧凑,流量是1.9～4.2m3/h,扬程为一级叶轮增压至2kPa,转速为一级增速至9900r/min,增速齿松的模数为1,精度6级,制造精度和装配要求相当高,而且由于是独家研制,该泵的零配件价格较高,一副齿轮的价格是
60000 series of single-sided deep groove ball bearings with dust cover to prevent dirt from entering the bearings from the outside, mainly used in the installation of dust-proof devices are difficult to install parts or structures. According to this feature, we use this bearing in chemical high-speed pump and achieved good results. I plant GWA-Ⅱ benzene feed pump is developed by Shanghai Chemical Industry Research Institute of aluminum alloy high-speed pump, the pump compact, compact structure, the flow rate is 1.9 ~ 4.2m3 / h, lift the first stage impeller to 2kPa, speed For a level of growth to 9900r / min, the rate of tooth growth loose modulus of 1, accuracy of 6, the manufacturing accuracy and assembly requirements are quite high, and because it is the exclusive development of the pump spare parts prices higher, a gear The price is
