ï¼æé«äºå·¥ä½æçã 4.design feature The shaft system is optimized and the rigidity and strength are improved greatly, which greatly improves the reliability of the pump, prolongs the pump's service life and reduces the operating and maintenance cost of the pump in the whole life cycle. 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. 5ãCHEæ³µç»æå¾ CHE pump structure diagram å¾1 CHEç³»åæ³µåé¢å¾ Fig. 1 CHE series pump profile CH泵主è¦é¶é¨ä»¶åç§°è¡¨ï¼ 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 6ãæ³µç¨ææ CHEåæ³µè¿æµé¨ä»¶ï¼æ³µä½ãå¶è½®ãæ³µçãè½´å¥ãå¶è½®èºæ¯ãæºå°åççï¼æ质类å«æéåéåéãéåéåéãåæ°åéãéåéåéãåç±»ä¸éé¢ãè磨æè´¨åç¹æ®ä»è´¨éæ±çç¹æ®èè
