抽油机驴头圆弧主焊缝焊接专机的研制 - Therefore , a highly efficient , low - friction oil pump unit was installed as a separate unit
因此，一个高效的、低磨察油泵作为一个独立单元来安装。 - Finally , some fault diagnosis cases about rolling contact bearing , oil pumping unit , especially twin - screw extruder are provided to demonstrate the establishment of multi - fault classifier . the property between c - svc and - svc and two kinds of agorthm between “ one - against - one ” and “ one against the other ” are made a comparison respectively and the simulation results are given . meanwhile , the differences of generalization capability between svm and nn on the condition of small - sample are reflected when nn is applied to the same samples
文章主要介绍了两类故障分类器和多故障分类器的建立,比较了c -支持向量分类机和-支持向量分类机的性能以及“成对分类”和“一类对余类”两种多类分类算法的优缺点,同时,将神经网络应用在同样的实例上,反映了支持向量机与神经网络在少样本情况下的推广性能差异。 - Abstract : counterbalance problem of oil pumping unit is researched in detail , and it is pointed out that counterbalances of matching weight and gas pressure are two main types of counterbalance of oil pumping unit . the possiblity for oil pumping unit to use spring counterbalance or flywheel counterbalance is put forward
文摘:对抽油机的平衡问题作了细致的研究，指出配重平衡与气压平衡是抽油机的两种主要平衡方式，提出了采用弹簧平衡与飞轮平衡的可能性，说明了各种平衡方式的参数确定方法；指出提高抽油机效率的方法是提高电动机和传动机构的效率，并对后者作了分析与表示。
