Working principle of centrifugal pump

Main working principle:
(1) The impeller is driven by the pump shaft to rotate, the fluid located between the blades to do work, the fluid by centrifugal effect, by the impeller centre is thrown to the periphery. When the fluid reaches the periphery of the impeller, the flow rate is very high.
(2) The pump casing collects the liquid thrown out from between the blades, and these fluids flow in the casing in the direction of gradually expanding the worm shell-shaped channel, so that the kinetic energy of the fluid is converted into static pressure energy, reducing energy loss. So the role of the pump casing is not only in the collection of liquid, it is an energy conversion device.

Safe usage method of screw pump

1、 Shutdown of screw pump

When the screw pump is stopped, the discharge stop valve should be closed first, and the suction stop valve should be closed after the pump is completely stopped.

Screw pumps are prone to bending due to their long working screw length and poor rigidity, resulting in abnormal operation. The connection of the shaft system must be well aligned; It is best to perform centering work after installation and positioning to avoid deformation caused by pipeline entanglement; When connecting pipelines, they should be independently fixed to minimize interference with the pump. In addition, it is best to use a hanging and fixing method for spare screws during storage to avoid deformation caused by uneven placement.

The role of drilling blowout preventers

Drilling blowout preventers can generally be divided into several types: single ram, double ram, universal (annular), and rotary blowout preventers.

Application of flow meters

Flow measurement is one of the components of metrology science and technology, which is closely related to national economy, national defense construction, and scientific research. In the production of the petroleum industry, flow measurement runs through the entire process from oil extraction, transportation, refining and processing to trade sales, and every link cannot be separated from flow measurement.

The function of thread protectors

Thread protectors can be used as caps and bushings to protect and seal threads during loading, unloading, transportation, and storage. In addition to being able to perform professional sheath installation, it can also be used as a repair component. During the trial period, people can experience its superior stability and repair ability. So the use of thread protectors plays a particularly important role in the entire mechanical component.

Troubleshooting Mud Pump

Water pump vibration
★ Reason: The pump shaft is not concentric with the diesel engine (or motor), the impeller is unbalanced, and the bearings are damaged;
★ Solution: Adjust the concentricity, conduct balance testing on the impeller, and replace the bearings.
