Centrifugal pumps can be widely used in power, metallurgy, coal, building materials and other industries with the transport of solids containing slurry. Such as thermal power plant ash, metallurgical ore dressing plant, coal washing plant coal and heavy medium transport. Centrifugal pump work, the pump needs to be placed on land, suction pipe on the water, but also need to pump start. Mud pump and submerged centrifugal pump due to structural constraints, the work needs to be placed on the water above the motor, the pump into the water, it must be fixed, otherwise, the motor fell into the water will cause the motor scrapped. Moreover, since the length of the major axis is generally constant, it is troublesome to install and use the pump, and the application occasion is subject to many limitations. Architectural Aluminum Profile extrusion Dies
Architectural aluminum profiles are a commonly used building material and are widely used in various fields of the construction industry. It has excellent performance and various shapes, which can meet different building needs.

1, centrifugal pump should be shut down after the pump inlet valve closed, to be cooled and then turn off the auxiliary system of the valve.
2, high temperature pump parking should be implemented according to the provisions of technical documents, after parking should be 20-30 min each turn a half turn until the pump body temperature dropped to 50 ℃ so far.
3, cryogenic pump parking, when no special requirements, the pump should always be filled with liquid; suction valve and the discharge valve should be kept normally open state; using double-ended mechanical seal cryogenic pump, liquid level controller and pump seal chamber seal Fluid should maintain pump grouting pressure.
4, conveying easy to crystallize, easy to coagulate, easy precipitation and other media centrifugal pump, stop the pump should be blocked, and timely flush with water or other media pumps and pipes.
5, discharge the liquid stored in the pump to prevent corrosion and cracking.
Architectural aluminum profiles have good corrosion resistance. Aluminum can form a dense oxide film in the air, which can effectively prevent further corrosion of the aluminum. Therefore, aluminum profiles can maintain good performance and extend their service life in humid or corrosive environments. Architectural aluminum profiles have excellent processing properties. Aluminum has good plasticity and processability and can be made into profiles of various shapes and sizes through extrusion, cutting, welding and other processing techniques. This enables aluminum profiles to meet the needs of different architectural designs and be flexibly used in various parts of the building. Architectural aluminum profiles also have excellent thermal conductivity. Aluminum has a high thermal conductivity and can conduct heat quickly. This allows aluminum profiles to be used as heat dissipation components in buildings, effectively regulating indoor temperatures and improving energy efficiency.
Architectural aluminum profiles are a building material with a variety of excellent properties. Its light weight, high strength, corrosion resistance, excellent processing performance, as well as good thermal conductivity and decorative properties make it widely used in the construction industry. With the development of science and technology and the continuous improvement of people's requirements for construction quality, architectural aluminum profiles will play a more important role in the future construction field.
Centrifugal pump to stop the maintenance
No matter how good the pump is , if it is not maintained, it will not achieve higher efficiency. Therefore, we should pay attention to some basic requirements when using the centrifugal pump. The following describes the centrifugal pump to stop working after the request.
