Germany KAYSEN imported stainless steel centrifugal pump overview
The horizontal single-stage single-suction centrifugal pump adopts the most advanced hydraulic model. It is designed according to the performance parameters of the IS-type single-stage single-suction centrifugal pump and the unique structure of the vertical pump. It is designed and manufactured in strict accordance with the international iso2858. The hard alloy mechanical sealing device is adopted, which has the characteristics of high efficiency, energy s***ing, reliable performance, convenient installation and use.
Through the characteristic curve of the stainless steel centrifugal pump and the pipeline system, several main ways of adjusting the flow of the centrifugal pump are analyzed: the outlet valve adjustment, the pump shift regulation and the series and parallel adjustment of the pump. The characteristic curve is used to analyze the energy loss of the two methods of outlet valve regulation and pump speed regulation. The comparison shows that the variable speed regulation flow of the centrifugal pump can s***e energy and s***e energy by adjusting the flow rate with the outlet valve. It is related to the size of the flow change. In practical applicati***, attention should be paid to the range of shift regulation to better apply the centrifugal pump shift regulation.
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), ***all size, simple structure, easy operation, low operating costs and many other advantages. Usually, the flow rate and pressure head of the selected centrifugal pump may be inc***istent with the requirements in the pipeline, or due to changes in production tasks and process requirements. 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 variable speed 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 c***umption, the most energy-s***ing flow regulation, it is necessary to fully understand the flow regulation of the centrifugal pump. The relati***hip between mode and energy c***umption.
main feature:
The stainless steel centrifugal pump cover is fixed to the intermediate bracket through the stop, and then the pump cover is clamped in the middle by the connection between the pump body and the intermediate bracket. The pump body is axially sucked, radially discharged, and the foot is supported and can be directly fixed. On the base, the suspension component is fixed on the intermediate bracket through the stop, and is supported on the base by the suspension bracket. For the convenience of disassembly, the extension coupling is designed, and the inlet and outlet connection pipeline, the pump body and the electric motor. Simply remove the intermediate coupling of the long coupling and exit the rotor assembly for inspection. This is a common form of structure in the world. The seal type of the pump adopts packing seal or mechanical seal, which is selected by the user as needed, and other types of shaft seal type (such as mechanical seal with bellows and impeller seal) which are suitable for the sealed c***ity size specified by IS03069 are allowed as required. and many more).
The main advantage:
● Convenient maintenance: replacement of seals, bearings, and simple land occupation: the exit can be left, right, and upward, and the pipelines are installed and installed to s***e space.
● ***ooth operation: absolute concentricity of the pump shaft and excellent dynamic and static balance of the impeller ensure ***ooth operation and no vibration
●Low noise: The pump under the support of two low-noise bearings runs ***oothly. Except for the weak sound of the motor, there is basically no noise.
● Low failure rate: the structure is simple and reasonable, the key parts adopt the international first-class quality matching, and the whole machine has no troubles.
●Drip water does not leak: Carbide seals of different materials ensure no leakage in different media delivery
