现在,应用最多的液压泵主要有齿轮泵、叶片泵、柱塞泵等。其中,齿轮泵的构造最简单,价格最便宜,自吸性能最好,抗油液污染的能力最强,但它的其它方面性能都较差,尤其是内泄漏较严重,容积效率低,难以应用到高压系统中去。在此介绍一种陶瓷镀膜齿轮泵,这种齿轮泵很好地解决了齿顶间隙的密封问题,有助于提高齿轮泵的容积效率及工作压力。一、陶瓷的特点陶瓷材料的主要特点有:1、硬度高;2、耐磨性好;3、耐腐蚀性强。其中硬度高是本文所述的用来解决齿顶间隙密封问题的重要条件。
Now, the most widely used hydraulic pump gear pump, vane pump, piston pump and so on. Among them, the most simple structure of the gear pump, the cheapest price, best self-priming performance, the ability to resist the strongest oil pollution, but its performance in other areas are poor, especially more serious internal leakage, low volumetric efficiency, difficult Applied to high-pressure system. Here is a description of a ceramic coating gear pump, this gear pump to solve the problem of tooth space seal, help to improve the volumetric efficiency of the gear pump and working pressure. First, the characteristics of ceramic The main characteristics of ceramic materials are: 1, high hardness; 2, good wear resistance; 3, strong corrosion resistance. The high hardness is the important condition described in this paper to solve the problem of addendum clearance sealing.
