2) pumping performance
泵送性能
1.
By the analyse of change course about low temperature pumping performance testing method of engine oil, we put forward the necessity of analysing the low temperature pumping performance particularly to the used engine oil, and the effect factor of low temperature Pumping Performance and Re-tentivity of Engine Oil are described in this article.
通过对车用发动机油低温泵送性能测试方法的变化过程的分析,提出了发动机在用油低温泵送性分析的必要性,论述了发动机油低温泵送性及其保持性的影响因素。
2.
However, its pumping mechanism has not been fully understood and a study of its pumping performance has still been in a primary experimental stage.
但其泵送机理至今仍不十分清楚,对泵送性能的认识也仅停留在初级试验阶段,泵的设计和使用是基于大量的未经理论分析和整理的试验数据,因而存在很多不确定性因素,极大限制了迷宫螺旋泵的推广应用。
3.
Under the condition of the same proportion,same slump,there is no significant difference on the pumping performance between the tailing dinax and the natural dinax;with the same proportion,the cohesive property and water-retaining property of the iron tailing dinax are worse than the natural dinax concrete.
研究分析表明,在用水量相同、水灰比相同、外加剂用量基本相同的情况下,尾矿砂石混凝土的坍落度小于天然砂混凝土;配合比相同、坍落度相近时,尾砂石混凝土与天然砂石混凝土泵送性能相差无几;相同配合比时,铁尾矿砂石混凝土的黏聚性和保水性略差于天然砂石混凝土。
3) low temperature pumpability
低温泵送性
4) pumpability
可泵性;输送量;泵送能力
5) borderline pumpability
边界泵送性能
1.
The borderline pumpability of engine oil is closely bound up with oil supplying and engine lubricating at low temperature.
发动机润滑油的边界泵送性能与发动机在低温下能否及时正常供油和润滑密切相关,边界泵送性能不好将导致润滑油不能及时到达润滑部件,致使发动机运动部件严重磨损。
6) low-temperature pumpability
低温泵送性能
