Below is an introduction to the characteristics of axial flow pumps

　　1. Working principle of axial flow pump

　　The working principle of an axial flow pump is different from that of a centrifugal pump. It mainly uses the thrust generated by the high-speed rotation of the impeller to lift water. When the blades of the axial flow pump rotate, the lift force on the water can push the water up from the bottom.

　　The blades of the axial flow pump are generally immersed in the water pool of the water source to be sucked. Due to the high-speed rotation of the impeller, under the lifting action of the blades, the water is pushed upward one by one, causing the water to flow out along the outlet pipe. As the impeller continues to rotate, the water is continuously pressed upwards.

　　2. Characteristics of axial flow pumps

　　(1) In an axial flow pump, the flow direction of water is axial suction and axial discharge of the impeller, hence the name axial flow pump.

　　(2) Low head (1 ~ 13 meters), large flow rate, high efficiency, suitable for irrigation and drainage in plains, lakes, and river network areas.

　　(3) No need to fill water before starting, simple operation.

　　(4) In the future, it will be composed of motor needles, and the type of motor needles can be effectively selected to reduce the manufacturing cost. The emergence of slender motors is conducive to improving the efficiency of the pump.

　　(5) The insulation layer of the motor stator, each link is equipped with over-temperature and over-voltage protection, and the internal design scheme of the motor maintains the temperature of the rolling bearing.

　　(6) Cylindrical roller bearings and deep groove ball bearings are used to withstand radial and axial forces to ensure that the arc wall is very short, reduce shaft deviation, improve the sealing performance and service life of rolling bearings, reduce vibration and ensure stable operation.

　　(7) For stainless steel axial flow pumps with large total flow rate, centrifugal water will be extracted from the motor casing to ensure motor cooling.

　　What are the characteristics of stainless steel axial flow pumps?

　　Stainless steel axial flow pumps are common commodities in wastewater treatment equipment, but many friends who need to purchase this kind of commodity are not very familiar with the characteristics of stainless steel axial flow pumps. Below are some characteristics of stainless steel axial flow pumps for your reference:

　　1. Convenient equipment, saving engineering investment: The motor and pump are combined into one, eliminating the complicated process of time-consuming and labor-intensive center line alignment equipment on site, which is very convenient; because the water pump enters the water, the building structure engineering of the wastewater treatment plant can be greatly simplified, the total equipment area can be reduced, and the total engineering cost of the wastewater treatment plant can be saved by 30 ~ 40%.

　　2. Reverse torque installation: The reverse torque of the motor starting torque always causes the generator set to rotate in reverse. A realistic reverse torque device can easily solve this problem.

　　3. Durable and moisture-proof cables: Using acid and alkali-resistant super-heavy rubber sheathed cables, the group outlet adopts a unique sealing structure to prevent water leakage, ensure long-term firmness, and there is no essential dew in the motor cavity.

　　4. Safe and firm: Two or several sets of independent mechanical seals are installed in series on the left and right sides, with friction auxiliary materials, showing multiple maintenance, long service life, and firmness.

　　Thank you for watching. I won't introduce more today. I wish you a happy life.
