Maintenance Tips for Vertical Axial Flow Pump
Common faults of vertical axial flow pumps include problems such as no or low water output after startup, large vibration or noise, sudden rise or low current, and high temperature of the bearing housing. So what are the reasons for these problems, and what methods should be used to solve them? Let's take a look below.
The treatment method of the axial axial pump does not produce water or the amount of water is small. The impeller submergence depth is insufficient. The treatment method is to adjust the impeller submergence depth. The impeller is not turned correctly. The pin is broken, the treatment method is to replace the blade or the positioning pin; the pump inlet or the impeller is blocked by debris, the treatment method is to clear the debris; the pump shaft is detached, the treatment method is to reassemble or replace the pump shaft.
Vertical axial flow pump is a vane pump. This pump has the characteristics of large flow, low head, high specific speed, high efficiency, small footprint, variable performance parameters, and suitable for low water conditions. Therefore, it often becomes the preferred pump type for agricultural drainage and irrigation, urban water supply and drainage, and circulating power transmission in thermal power plants. The vertical axial flow pump draws water from the pool through the suction horn tube. Because the blades of the impeller in the impeller force the water to rotate, the water enters the guide vane, and the energy is converted to generate a lift. discharge. The pump is coupled to the intermediate shaft via a coupling (rigid). The bearing under the motor support bears all the downward axial force of the rotor. The intermediate shaft and the motor shaft are connected with an elastic coupling.
I believe that everyone is familiar with vertical axial flow pumps. Today we will briefly introduce the two debugging methods after our vertical axial flow pump installation. I hope it will be helpful to everyone. Let's go together Let's see!
Variable angle adjustment. From a structural point of view, the vertical axial flow pump impeller has a huge hub, which is convenient for installing adjustable angle blades. When the blade installation angle is changed, the lift force of the blade on the water is also changed, which changes the working performance of the water pump. This is the variable angle adjustment of the vertical axial flow pump. With the increase or decrease of the blade installation angle, the flow, head, and power of the vertical axial flow pump change accordingly, but the highest point of efficiency has not changed, which is extremely beneficial to the performance adjustment of the vertical axial flow pump.
