What Should I Do When The Current Of The Tailings Slurry Pump Is Too High? Here Are Some Tips For Yo

What should I do when the current of the tailings slurry pump is too high? Give you tips:

The tailings slurry pump is divided from another angle, that is, from the conveying medium. As the name suggests, the slurry pump delivers a mixture of solid particles containing residue and water. But in principle, the slurry pump is a type of centrifugal pump. The main working parts of the centrifugal pump are the impeller and the casing. The impeller device in the casing is located on the shaft and is connected to the prime mover to form a whole.

When the prime mover drives the impeller to rotate, the blades in the impeller force the fluid to rotate, that is, the blades do work on the fluid in its direction of movement, thereby forcing the pressure potential and kinetic energy of the fluid to increase. At the same time, under the action of inertial force, the fluid flows from the center to the edge of the impeller, and flows out of the impeller at a very high speed, enters the pressure outlet chamber, and is discharged through the diffusion pipe. This process is called the water pressurization process.

At the same time, since the fluid in the center of the impeller flows to the edge, a low pressure zone is formed in the center of the impeller. When it has sufficient vacuum, under the action of the pressure at the suction end (usually atmospheric pressure), the fluid enters the impeller through the suction chamber. This process is called the water absorption process.

Due to the continuous rotation of the impeller, the fluid is continuously discharged and sucked in, forming a continuous work. This working process is actually a process of energy transfer and transformation. It transfers the mechanical energy of the motor at high speed through the pump blades and converts it into the pressure and kinetic energy of the pumped fluid.

When the tailings slurry pump is working, the pump needs to be placed on land, the suction pipe is placed in water, and the pump needs to be started. Due to structural limitations, the motor needs to be placed on the water surface during operation and the pump is placed in the water, so it must be fixed. Otherwise, the motor will fall into the water and will cause the motor to be scrapped.

Moreover, since the length of the long shaft is generally fixed, the pump is more troublesome to install and use, and the application situations are subject to many restrictions.

Based on years of experience in use, we found that the tailings slurry pump sometimes has too high current when used. What should we do at this time? Let’s take a look together!

The reasons for the high current of tailings slurry pump are as follows:

Situation A: The relative density and viscosity of the process medium exceed the index.

Solution: Check whether the material components so that their viscosity and relative density match the design value, and adjust it by the process operator.

Situation B: Electrical failure.

Solution: Check the setting value of the circuit breaker heater, check the voltage, the three-phase current should be balanced, and the error should not be greater than 3%.

Situation C: When the pump is started, the outlet valve is fully opened, and the resistance in the outlet pipeline is too small.

Solution: Close the outlet valve, slowly open the outlet valve after the tailings slurry pump is started.
