The series pump parts are of high generalization and standardization, and the specifications of pump parts and standard parts are reduced to the minimum, which reduces the types and specifications of pump parts and is easy to manage. when the temperature of the medium is higher than 120 DEG C , the bearing box body is provided with a water cooling system , and the lubricating oil can be cooled ; a cooling cavity is arranged at the pump cover , the mechanical sealing cavity can be cooled , the working environment of the machine is improved , and the service life of the machine is prolonged . Using German patented self-locking washer, the impeller nut will not be loosened under the condition of pump reversal or vibration, and the environmental requirements for operation and installation have been reduced to a certain extent. The CHE series pump adopts closed or open impeller, and the large flow pump adopts double volute type pump body, which can balance the axial force effectively with the combination of seal ring and balance hole. According to the difference of conveying medium, all kinds of mechanical seals of non-container type or container type, single or double end face and corresponding sealing auxiliary system can be adopted to realize reliable sealing and cooling. The machine seal flushing and executing various schemes in API682 standard. Che series pumps can also adopt special mechanical seal structure, which is especially suitable for medium containing solid particles, at the same time, the requirement of user field is greatly reduced. Adopt radial partition structure design, bearing part, impeller, seal body, pump cover and so on constitute a combination component, through the use of extended diaphragm coupling, no need to remove the pipeline and motor, in the production equipment overhaul can be carried on the whole machine overhaul and maintenance; On the basis of referring to the structure of the pump in the market and combining with the practical operation experience, the structure of the bearing system is optimized, which can realize the quick and simple disassembly and assembly, and improve the working efficiency. 5、CHE泵结构图 CHE pump structure diagram 图1 CHE系列泵剖面图 Fig. 1 CHE series pump profile CH泵主要零部件名称表: CH pump main parts name list: 1 impeller nut 2 Impeller mouth ring 3 Pump body orifice ring 4 pump body 5 impeller 6 pump bonnet 7 gland 8 Machine seal assembly 9 Dust plate 10 Bearing cover (pump end) 11 cylindrical roller bearing 12 oil ga(u)ge 13 ring 14 Bearing box body 15 axle 16 abat-vent 17 angular contact ball bearing 18 oil slinger 19 Bearing cover (motor end) 20 Dust plate 6、泵用材料 CHE型泵过流部件(泵体、叶轮、泵盖、轴套、叶轮螺母、机封压盖等)材质类别有钛及钛合金、锆及锆合金、哈氏合金、镍及镍合金、各类不锈钢、耐磨材质及特殊介质需求的特殊耐腐蚀材质等。 è¯´æ˜Žï¼šå½“ä»‹è´¨æ¸©åº¦è¾ƒé«˜æ—¶ï¼Œè½´æ‰¿ç®±ä½“é…ç½®å†·å´ç³»ç»Ÿã€‚è¯¥å†·å´ç³»ç»Ÿä¸ºé›†æˆå¼ï¼Œåªéœ€å¯¹åŽŸè½´æ‰¿ç®±ä½“ç®€å•åŠ å·¥å°±å¯å®‰è£…è¯¥å†·å´ç³»ç»Ÿã€‚ 机械密封组装图如下: 6.Pump material CHE pump overflowing parts (pump body, impeller, pump cover, shaft sleeve, impeller nut, machine seal gland, etc.) material categories are titanium and titanium alloy, zirconium and zirconium alloy, Hashi alloy, nickel and nickel alloy, all kinds of stainless steel, Wear-resistant materials and special medium requirements of the special corrosion-resistant materials and so on. Note: when the medium temperature is high, the bearing box is equipped with cooling system. The cooling system is integrated and can be installed by simply machining the original bearing box.
