Introduction to energy saving system - Overview
HSLG series high-efficiency and energy-saving pumps are developed by our company in cooperation with the pump manufacturer in recent years, and the new generation of high-efficiency and horizontal split centrifugal pumps are produced by adopting the excellent pump energy-saving technology of Austria andelitz; It complies with GB / t19762, iso9906, iso9908 and other standards, and has the advantages of high efficiency, energy saving, low pulse, low noise and convenient maintenance. It belongs to BB1 structural form - single-stage, double suction, volute type, horizontal split, and support at both ends. It is a high-efficiency and energy-saving product independently developed in response to the needs of the energy-saving market and combining the advantages of the same type of centrifugal pumps produced by well-known manufacturers at home and abroad. The current advanced three-dimensional flow design, CFD simulation technology and Andritz technology are used to realize the optimal hydraulic model. The efficiency is at the leading level in the world, and it has many advantages such as excellent structure, stable operation, low noise, and convenient maintenance and repair, so it is widely used in the power industry, water conservancy industry, steel industry, petrochemical industry, municipal engineering, shipbuilding industry and other occasions
HSLG pump structure has strong versatility, high degree of serialization and standardization. When the impeller shaft hole is the same, except the impeller, mouth ring and shaft, all bearing parts and shaft sleeve are standard parts. 2.3 HSLG series pumps use three-dimensional flow design theory, mature fluid simulation technology and finite analysis technology to design pumps with the efficiency reaching the world's advanced ranks, low operating cost, high strength and stable operation. HSLG series pump impeller is composed of two single suction impellers symmetrically, which can automatically balance axial force and ensure stable pump operation.
The products used by the water pump: the impeller is made of stainless steel, and the supporting bearing is made of S K F brand. The mechanical seal used is directly formed according to the assembly size of the water pump customized by Hesheng Longgang company. It is supplied in series and can be directly assembled without adjustment; 4) Pump body design: the pump body is made of HT. The pump body adopts double volute design, which can balance more than 80% of the hydraulic radial force, greatly reduce the radial force borne by the bearing, and prolong the rotor life by 50% - 80% compared with the general single volute pump body. 5) Pump shaft design: the pump shaft is designed and thickened according to the requirements of Hesheng Longgang company, and the rigidity and strength of the shaft are improved. As the pump shaft is thickened, the bearing used is increased by 2-3 gears compared with the pump of the same specification of the same manufacturer, which improves the bearing capacity of the bearing and greatly extends the operating life of the pump. The bearing bush is used to facilitate the disassembly of the bearing. The shortened wheelbase is beneficial to reduce the dynamic deflection of the shaft and prolong the service life of the bearing. The equal diameter shaft design is adopted. Compared with the stepped shaft structure of SH and s pumps, there is no stress accumulation effect and no risk of shaft breaking. This is very important for large-diameter pumps with large torque. The pump shaft is completely sealed with a stainless steel shaft sleeve, which does not contact the transmission medium, thus avoiding corrosion and prolonging the service life by 60%. Chongqing Hesheng Longgang Technology Co., Ltd. is responsible for the spare parts used for the technical transformation of this energy-saving system. After the technical transformation, customers can not only get an equipment update, but also get high power saving income.
