Mixed flow centrifugal pump has many advantages, such as wide performance adaptability, small size, simple structure, easy operation and low operating cost. Usually, the flow rate and pressure head of the selected centrifugal pump may be inconsistent with the requirements in the pipeline, or due to changes in production tasks and process requirements, the flow adjustment of the pump is required at this time, which is essentially to change the working point of the centrifugal pump.

The layout requirements and methods of mixed flow centrifugal pumps are similar, but as the basis for whether the mixed flow centrifugal pump can be normal and stable, the knowledge of layout should also be mastered.

First of all, let’s talk about the arrangement of mixed flow centrifugal pumps. It can be arranged in the open air, or in the semi-open air, or even directly indoors. When it is arranged in the open air, it is generally under or on the side of the pipe gallery, or it can be arranged near the suction equipment, mainly because these positions are well ventilated and easy to operate and maintain.

The reason why the mixed flow centrifugal pump is chosen to be arranged in the semi-open air is mainly for rainy areas. The pump can be arranged under the pipe gallery, and the ceiling can be set up on the upper part of the pipeline; or the pump can be arranged on the lower ground of the frame, so that the The frame platform serves as the ceiling.

In some cold and sandy areas, where it is known that the process has special requirements, indoor layout is a better choice for mixed flow centrifugal pump, which can protect the equipment enough and reduce the damage caused by external environmental factors. adverse effects.

For the mixed flow centrifugal pump arranged in the open air or semi-open air, the axis of the pump and the prime mover is required to be perpendicular to the axis of the pipe gallery; while for the pump arranged indoors, when the temperature of the transported liquid is higher than the self-ignition point or the transported liquid is liquid hydrocarbon, it should be They are arranged in their own rooms with other pumps and separated by firewalls.

Moreover, the net distance between the pump end or the pump side and the wall, and the net distance between the two rows of pumps cannot exceed the specified standards. Of course, how to arrange depends on the specific type and specification. In short, it is necessary to ensure that the mixed flow centrifugal pump can be Normal operation, but also to facilitate future inspection and maintenance.
