Clean water centrifugal pump for industrial and urban water supply, drainage, can also be used for agricultural irrigation and drainage for the delivery of water or physical and chemical properties similar to other liquids used in water, the temperature is not high 80 ℃.
1, according to the international standard ISO2858 provides the performance and size of the design, mainly by the pump, pump cover, impeller, shaft, seal ring, sleeve and suspension bearings and other components.
2, the pump body and pump cover part, is divided from the back of the impeller, that is commonly referred to as the back door structure. The advantage is easy maintenance, maintenance does not move the pump body, suction pipe, discharge pipes and motors, just remove the coupling of the middle coupling, you can exit the rotor part of the maintenance.
3, the shell (that is, pump and pump cover) constitute the pump of the studio. Impeller, shaft and rolling bearings for the pump rotor. The suspension bearing member supports the rotor portion of the pump, and the rolling bearing is subjected to the radial force and axial force of the pump.
4, in order to balance the pump axial force, most of the pump before and after the impeller is equipped with a seal ring, and in the impeller rear cover with a balance hole, because some pump axial force is not large, the impeller is not sealed on the back Ring and balance hole.
5, the axial seal ring is composed of packing gland, packing ring and packing, etc., to prevent the intake or a lot of water leakage. If the impeller of the pump is balanced, the cavity with the soft packing is connected with the impeller inlet. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to enter the surface along the surface of the sleeve. Therefore, Pump hole on the hole, the water centrifugal pump chamber pressure water lead to the packing ring for sealing. If there is no balance hole in the impeller of the pump, the liquid pressure on the back of the impeller is greater than the atmospheric pressure, so there is no leakage problem.
6, in order to avoid shaft wear, in the shaft through the packing cavity parts with sleeve protection. There is an O-ring between the sleeve and the shaft to prevent ingress or leaking along the mating surface.
7, the transmission method by lengthening the elastic coupling and the motor connection, the direction of rotation of the pump, from the drive side, for the clockwise rotation.
成立于1852年创建于门兴格拉德巴赫（Monchengladbach）是位于德国北莱茵-威斯特法伦州首府杜塞尔多夫市以西的一座城市。于19世纪50年代初德国经济快速发展，由于德国能源短缺，政府在节能方面加大力度，因此HANK(Trouble Less pump没有故障的水泵)公司成立。汉克水泵是以生产高品质、先进的水泵、测量及控制系统而享誉全球的跨国性生产企业，在全球几十个国家拥有子公司及分支机构，公司产品涉及用途：石油、化工、电力、冶金、制药、食品、水处理、市政给排水、天然气、造纸、电子工业、楼宇、机械设备配套等领域。
GERMANY HANK PUMP LIMITED is founded on 1852 in Monchengladbach,which is located at one city in North Rhine in Germany, which is the west of Nordrhein-Westfalen. At the beginning of 1850s, as the rapid development of economic and the shortages of energy in Germany , the government had been in saving energy aspect. On this occasion, HANK Pump (Trouble Less Pump) was established.Hank pump is the world-famous transnational production enterprise,which produces high quality and advanced pump, measurement and control system, and which has its divisions and branches in dozens of countries in the global. The company products user involves the petroleum, the chemical industry, the electric power, the metallurgy, the drugs manufacture, food, the water treatment, the municipal administration to give draining water, the natural gas, the papermaking, the electronics industry, the building, the mechanical device necessary ect..
The conclusion of the pump concept in German Hank pump is resposibility,foresight,innovation. For ourselves resposibility, foresight and focusing on creating unprecendented solution and concept,our company has become the lead of pump manufacturer in the global.标签:   清水离心泵 进口清水离心泵
