Gas liquid-pumping device

Abstract

The invention relates to a gas liquid-pumping device, comprising a nozzle, a cylinder body, a diffusion pipe and a liquid-pumping pipe. A suction cavity is arranged in the cylinder body; the nozzle is arranged in the cylinder in a penetrating manner; the front end of the nozzle is located in the suction cavity, and the rear end of the nozzle is located outside the cylinder; the diffusion pipe is communicated with the cylinder body; the liquid-pumping pipe is communicated with the cylinder body; axes of the nozzle, the cylinder and the diffusion pipe are located on the same straight line; and the nozzle is connected with the cylinder body through threads. The gas liquid-pumping device has the advantages of green energy conservation, convenience in installation and use, simple structure, low maintenance cost, long service life, high security and reliability, large suction vacuum degree, and strong liquid delivery capacity.

Description

AI Technical Summary

Problems solved by technology

[0004] When lifting or transporting some acidic and corrosive liquids, mechanical chemical centrifugal pumps, process pumps and other moving equipment need to choose some acid-resistant and corrosion-resistant materials, such as ceramics, PTFE, plastics, etc., but due to the complex structure of impellers and other components , the processing cost is high, and the installation and maintenance are also very inconvenient

[0005] When lifting or transporting some liquids with large specific gravity and solid particles, mechanical chemical centrifugal pumps and process pumps are prone to impeller wear and component damage.

[0006] Mechanical chemical centrifugal pumps, process pumps and other moving equipment need to consume a lot of energy when transporting high-viscosity fluids, the energy utilization rate is low, and the motor is often overloaded, which increases the cost of equipment maintenance
