Main characteristics of stainless steel centrifugal pump
1, running smoothly: the absolute concentricity of the pump shaft and the excellent dynamic and static balance of the impeller, so as to ensure smooth operation and no vibration.
2, leakproof: hard alloy seal with different materials to ensure the transportation of different media without leakage.
3, low noise: two low noise bearings under the support of the pump, smooth operation, in addition to the motor weak sound, basically no noise.
4, the failure rate is low: the structure is simple and reasonable, the key part adopts the international first-class quality matching, the whole machine work time without fault is greatly improved.
5, convenient maintenance: replacement of seals, bearings, simple and convenient.
6, the area is more provincial: the export can be left, right and upward three directions, then the pipe is arranged and installed, and the space is saved.
The installation method of stainless steel centrifugal pump:
(1) the base surface of the installed base must be flat, clean and able to bear the corresponding load; (2) the anchor bolt should be used in the place where it is fixed.
(3) for vertically mounted pumps, the anchor bolts must have sufficient strength;
(4) if vertical installation, the motor must be located above the pump;
(5) when fixed on the wall, pay attention to finding the right, in the middle;
The difference between the stainless steel centrifugal pump and the cast iron pump:
The cast iron is magnetic, and the stainless steel is not magnetic. The sound of the cast iron is stuffy, and the stainless steel is crisp. Cast iron used in the general water supply and drainage is much more, and stainless steel in the chemical industry is more (corrosion medium).
Why does the stainless steel centrifugal pump replace the cast iron pump?
The energy saving effect of the stainless steel centrifugal pump is obvious. Pump is a large energy consumption, according to the estimated 20% of the country's power generation is consumed by the pump, so the efficiency of the pump will be more efficient in saving energy. The hydraulic efficiency of the stainless steel centrifugal pump is higher than that of the same kind of cast iron pump by about 10% - 20%.
The stainless steel centrifugal pump can avoid the &ldquo of the water quality; two times the pollution ”
Iron and stainless steel are all raw materials for making pumps. Relatively speaking, the advantages of stainless steel centrifugal pumps are obvious. In the future, stainless steel centrifugal pumps instead of cast iron pumps are the general trend.
But the purchase cost of stainless steel pump is 20% to 30% higher than that of cast iron pump. Currently, it is relatively less applied in three or four tier cities and Midwest areas of eastern China, and there is a larger alternative space. The Ministry of finance will include pumps, such as centrifugal pumps, which have energy saving effects into the subsidy range, or will speed up the process of replacing the cast iron pump with stainless steel.
