Embodiment Construction

[0016] 1. The structure of the vortex impeller of the special pump for the burner is described in detail in conjunction with the special pump for the burner. The structure of the vortex impeller of the special pump for the burner meets the characteristics of transporting organic combustible clean fuel. Its features include the inner diameter of the vortex impeller hub (1) and the pump shaft. Clearance fit, can be matched with the key on the shaft, or with the optical shaft, such as: ceramic shaft. Easy to install and disassemble.

[0017] 2. The impeller hub (1) is provided with a keyway and a positioning seal groove hole (5) on the inner circle, and the convex structure on the upper part of the pump mechanical seal is positioned in the seal groove hole (5), driving the whole set of machinery The seal moves in a moving ring, and the structure is simple and scientific.

[0018] 3. There are blades (4) on the outer circumferential ring of the impeller, which is characterized in...

Abstract

The invention provides a vortex impeller of a pump special for a combustor, and belongs to the technical field of an impeller for a mechanical environment-friendly pump. According to the vortex impeller of the pump special for the combustor, clean fuel such as alcohol-based fuel, natural gas, biomass energy and aromatic group oil is used, and the vortex impeller is characterized by comprising a vortex impeller hub (1), a blade (4), a sealing face (3), a sealing groove (2), a blade R angle (7), a positioning sealing part groove hole (5), an axial pressure adjusting hole (6), a sealing partition (8) and a sealing cavity (9). The vortex impeller is simple in structure, high in practicability, and suitable for the characteristics that biomass fuel oil is low in viscosity, easy to volatilize and vaporize, low in density and lubrication and the like, long-time ceaseless conveying needs of organic combustion mass can be fully met, and the pump efficiency is greatly improved.

Description

technical field [0001] A vortex impeller for a special pump for a combustion engine belongs to the impeller for mechanical environmental protection pumps, including the technical field of combustion engine pumps using clean fuels such as alcohol-based fuel, natural gas, biomass energy, and aromatic hydrocarbon-based oil. Background technique [0002] Due to the air smog caused by the use of coal-fired boilers, it is necessary to use organic combustion substances to replace traditional coal-fired heating, including burners using clean fuels such as alcohol-based fuels, natural gas, biomass energy, and aromatic hydrocarbon-based oils. There is an urgent need for special burners suitable for burners The pump solves the problem of liquid delivery of the existing burner pumps using clean fuels, including alcohol-based fuels, natural gas, biomass energy, and aromatic hydrocarbon-based oils. Due to the characteristics of low viscosity, easy volatilization, easy vaporization, low de...
