机械密封具有密封性能好、寿命长和消耗功率少等优点,因此,它适宜用在对旋转轴密封处有较高要求的设备上,可取代填料、橡胶油封等密封型式。结构原理我厂生产的农用 D22～D35型机械密封,为内装式非平衡单端面型式,其结构见图。该密封装置由7个零件组成:静环6和静环座7被紧压在泵体内,动 Mechanical seal with good sealing performance, long life and low power consumption, etc. Therefore, it is suitable for use on the shaft seal has higher requirements of the equipment, can replace the packing, rubber seal and other sealed type. Structure principle I plant the agricultural D22 ~ D35 mechanical seal, built-in unbalanced single-end type, the structure shown in the figure. The seal consists of seven parts: the stationary ring 6 and the stationary ring seat 7 are pressed against the pump body, moving
