Gas etching prevention type centrifugal pump and operating method thereof

Abstract

The invention discloses a gas etching prevention type centrifugal pump. The gas etching prevention type centrifugal pump comprises a centrifugal pump, and is characterized by further comprising a water storage pipe section, a water suction pipe section and a piston pumping pipe section, wherein the centrifugal pump is connected with the water storage pipe section by virtue of a water pipe; one end of the water suction pipe section is connected with the water storage pipe section; the other end of the water suction pipe section is connected with a water storage device; one side of the water storage pipe section is connected with the piston pumping pipe section; and one end of the piston pumping pipe section is connected with a motor. The gas etching prevention type centrifugal pump disclosed by the invention has the benefits that a section of water inlet pipe is mounted at the water inlet of the original centrifugal pump, and air sucked by the centrifugal pump is reduced, so that an effect of protecting the blades and the motor of the centrifugal pump is achieved, and the gas etching problem caused to the blades and an air bind phenomenon to the motor can be avoided in the centrifugal pump operating process.

Description

technical field [0001] The invention relates to a centrifugal pump, in particular to an anti-cavitation centrifugal pump and an operation method thereof, belonging to the field of water pumps. Background technique [0002] Nowadays, water conservancy transportation is in a stage of rapid development, and centrifugal pumps play an important role in water conservancy transportation. Discharge, during which the fluid acquires kinetic and static energy. At the same time, the air inhaled by the centrifugal pump will cause serious cavitation to the blades of the centrifugal pump, causing great damage to the blades of the centrifugal pump. In severe cases, it will cause air binding to the motor and burn out the motor. For this reason, we have designed a new type of anti-cavitation centrifugal pump, which can solve the problem of cavitation caused by the centrifugal pump to the blades and the phenomenon of gas binding to the motor during work. Contents of the invention [0003] ...

AI Technical Summary

Problems solved by technology

At the same time, when the centrifugal pump sucks in air, it will cause serious cavitation to the centrifugal pump blades, causing great damage to the centrifugal pump blades. In severe cases, it will cause air binding to the motor and burn out the motor.

For this reason, we have designed a new type of anti-cavitation centrifugal pump, which can solve the problem of cavitation caused by centrifugal pumps to the blades and the phenomenon of gas binding to the motor during work.
