Which is a good mixed flow pump

Large flow mixed flow pump in stockIts working principle is to simultaneously carry out axial and radial flow of liquid, thereby generating mixed flow inside the pump body. Mixed flow pumps are typically used in situations where medium head and high flow are required. Suitable for high flow transportation and capable of efficiently handling large amounts of liquids. Working Principle:

Liquid enters the pump body: The liquid enters the pump body through the inlet of the pump.

Impeller design: The impeller of a mixed flow pump has both axial and radial blades. This design allows the liquid to flow both axially and radially inside the impeller.

Liquid pressurization: When the pump is started, the rotation of the impeller generates centrifugal force and kinetic energy, which pressurizes the liquid and pushes it to the outlet.

Mixed flow: Due to the design of the impeller, the liquid flows both axially and radially inside the impeller, forming a mixed flow that improves the efficiency and performance of the pump.

Liquid discharge: After the action of the impeller, the liquid is transported to the outlet of the pump body and then transported to the required place through the pipeline.

Large flow mixed flow pump in stockKey points for installation, use, and maintenance:
1. After assembling the pump, rotate the coupling to see if it rotates flexibly. Check if there is any metal friction sound and if the nuts of each component are tightened.
2. Check the concentricity between the pump shaft and the motor shaft. The difference between the outer circles of the upper and lower couplings should not exceed 0.1mm, and the gap between the coupling end faces should be maintained at 1-2.5mm.
3. The distance between the suction port of the pump and the bottom of the container is 2-3 times the suction diameter. The distance between the pump body and the wall should be greater than 2.5 times the diameter.
4. The outlet pipeline of the pump should be supported by a separate bracket, and its weight is not allowed to be supported on the pump.
5. Check the rotation direction of the motor to ensure that the pump rotates in the indicated direction.
6. Close the gate valve on the outlet pipeline and connect the cooling water pipe.
7. Overspeed the motor, slowly open the outlet pipe gate valve to the desired position, and put it into normal operation.
8. Regularly check the condition of the pump and motor. The temperature rise of the bearings should not exceed 75 ℃, and sufficient butter should be added to the bearing box.
