Of XiangDian ChangSha Pump Works6泵的轴向密封是由填料压盖（9） 、填料环（10）和填料（11）等组成，以防止进气或大量漏水。泵的叶轮如有平衡孔，则装软填料的空腔与叶轮吸入口相通，若叶轮入口处液体处于真空状态，则很容易沿着轴套表面进
15、气，故在填料腔内装有填料环，通过泵盖上的小孔，将泵室内压力水引至填料环进行密封。泵的叶轮如没有平衡孔，由于叶轮背向液体压力大于大气压，因而不存在漏气问题，故可不装填料环。为避免轴磨损，在轴通过填料腔的部位装有轴套保护，轴与轴套之间装有O 型密封圈，以防沿着配合表面进气或漏水。泵的传动方式是通过弹性联轴器与电动机联接的。泵的旋转方向，从电动机端看，为顺时针方向旋转。泵的尺寸见图 3 和表 2。泵的吸入口和排出口的法兰连接尺寸见图 5 和表4。3、装配和拆卸泵在装配前应首先检查零件有无影响装配的缺陷，并擦洗干净，方可进行装配。3.1、 预先可将各处的连接螺栓、丝堵等分别拧紧在相应的零件上；3.2、
16、 预先可将“O”形圈、纸垫、毛毡等分别放置在相应的零件上；3.3、 预先可将密封环和填料、填料环、填料压盖等依次装到泵盖内；3.4、 将滚动轴承装到轴上，然后装到悬架内，再合上压盖，压紧滚动轴承，并在轴上套上挡水圈。3.5、 将轴套装到轴上，再将泵盖装到悬架上，然后再将叶轮、止动垫圈、叶轮螺母等装上并拧紧，最后再将上述组件装到泵体内，并拧紧泵体、泵盖上的连接螺栓。湖南湘电长泵（长沙水泵厂）长一制泵有限公司ChangYi Pump Manufacturing Co.,Ltd. Of XiangDian ChangSha Pump Works7The shaft seal consists of
17、packing gland (9) water seal ring (10) and packing (11) to prevent air from in taking or the amount of leakage. If there is a balance hole of the impeller, cavity for soft packing connects to the impeller entrance. If liquid of the impeller entrance is at vacuum state, it is easy for air entraining
18、along the surface of the shaft sleeve. So water seal ring is in the stuffing box.Pressure water in the pump volute is led to water seal ring to be sealed. If there is no balance hole of the impeller, liquid pressure at the back face of the impeller is higher than atmosphere. There is no air leakage,
19、 so the water seal ring can not be packed.The shaft sleeve is on the shaft to avoid excessive shaft wear. There is “O” ring between the shaft and the shaft sleeve to prevent air entrance or water leakage along the matched surface. Drive is transmitted from the motor to the pump by a flexible couplin
