Stainless steel centrifugal pumps are a general-purpose fluid machine widely used in chemical industrial systems. It has a wide range of performance (including flow, pressure head and adaptability to the nature of the transport medium), small size, simple structure, easy operation, low operating costs and many other advantages. Generally, the flow rate and pressure head of the selected centrifugal pump may be inconsistent with the requirements in the pipeline, or the production task and process requirements may change. At this time, the flow adjustment of the pump is required, which essentially changes the working point of the centrifugal pump. The working point of the centrifugal pump is determined by the characteristic curve of the pump and the characteristic curve of the piping system. Therefore, changing the characteristic curve of any one can achieve the purpose of flow regulation. The flow adjustment mode of the centrifugal pump mainly includes the regulating valve control, the shift control, and the parallel and series adjustment of the pump. Due to the different principles of various adjustment methods, in addition to their own advantages and disadvantages, the energy loss is not the same. In order to find the best, the lowest energy consumption, the most energy-saving flow regulation, it is necessary to fully understand the flow regulation of the centrifugal pump. The relationship between mode and energy consumption.
Stainless steel centrifugal pump main features
1. Smooth operation: the absolute concentricity of the pump shaft and the excellent dynamic and static balance of the impeller ensure smooth operation and no vibration.
2, dripping water does not leak: different materials of hard alloy sealing, to ensure that no leakage of different media delivery.
3, low noise: the pump under the support of two low-noise bearings, running smoothly, except for the weak sound of the motor, basically no noise.
4. Low failure rate: The structure is simple and reasonable, the key part adopts the international first-class quality matching, and the trouble-free working time of the whole machine is greatly improved.
5, convenient maintenance: replacement of seals, bearings, simple and convenient.
6, the land is more provincial: the exit can be left, right, up, three directions, the pipeline is installed and installed, saving space.
