Characteristics of vertical axial flow pump :

1. It can transport clean water and mild sewage, the temperature of the medium can reach 40 ℃, and the pH value is 4-10;

2. Excellent water conservancy model, well-made, ensuring the performance requirements of users;

3. Double mechanical seal to reliably prevent water leakage. Due to the large axial force of large pumps, special thrust bearings are used. The structural design is reasonable, the lubrication is sufficient, the heat dissipation is good, and the bearing has a long service life.

4. The motor adopts F-level insulation, high temperature resistance, and is equipped with temperature protection, monitoring, leakage and other alarm devices;

5. It can be equipped with one-control-two to one-control-four control mode electric control cabinet, which can realize the automatic shutdown of the pump in the event of a failure, and the automatic start-up of the standby pump of the mixed-flow pump manufacturer ; retaining the fault signal (self-diagnosis) and other functions to ensure high operation reliability;

6. The motor pump is submerged into the water, the cooling conditions are good, the motor pump runs well, is stable, has small vibration and low noise;

7. Users can design underground pumping stations according to their needs to improve the environment.

8. The scale of the pumping station is small, the civil construction and building structure are simple, and the investment is greatly reduced, which can save 30% -40% of the cost of the pumping station project;

9, machine and pump integration, installation and maintenance save time and labor, saving costs;

10. The products are in series, the pump has a wide range of high-efficiency areas, meets the user's working conditions, is highly efficient and energy-saving, and has low operating costs;

11. Convenient management, low management and operating costs;

12, easy to achieve remote control and unattended.

The vertical axial flow pump unit runs normally, the body is stable, the sound is continuous and uninterrupted, and its vibration value is within the allowable range. The reasons for the vibration of the vertical axial flow pump are introduced below.

First, hydraulic factors cause vibration. As the vertical pump runs away from the high-efficiency zone, the flow rate is too large or too small; the design of the inlet pool does not meet the standards, resulting in bias flow, vortex, insufficient depth of submerged bell mouth, etc., resulting in poor water absorption; due to the high suction stroke, The design and construction of the inlet flow channel are not in accordance with the requirements of cavitation; the vibration caused by the clogging or damage of the blade flow channel due to the mixing of foreign matter.

Second, mechanical factors cause vibration. Due to exceeding the allowable eccentricity of the vertical pump and the motor, the coupling is improperly connected; due to poor installation, the horizontal deviation of the vertical pump exceeds the allowable value, resulting in deviation of the verticality of the pump; due to loose rotating parts, friction Or the rotor has poor stability: due to improper blade placement angle, crushing, falling off and debris around the blade, the rotor body is unbalanced; due to poor support of the inlet or outlet pipes, caused by the pipeline load of the vertical pump vibration.

Third, insufficient stiffness causes vibration. Due to insufficient strength of the pump casing or various parts; insufficient foundation strength or improper fixing of the anchor bolts, poor fastening; vibration caused by insufficient stiffness of the motor beam, etc.
