Description

Technical Field

[0001] This utility model relates to the field of emulsion pump technology, and more specifically, to a pump head assembly for an emulsion pump that prevents slippage. Background Technology

[0002] As the core power source of hydraulic supports in fully mechanized coal mining faces, the performance of emulsion pumps directly determines the support strength, response speed, and operational stability of the hydraulic supports, playing an irreplaceable role in ensuring efficient mining and safe operation in underground coal mines. The preparation of emulsions relies on the synergistic effect of the emulsion pump and its supporting emulsification device. The emulsion pump, as the power core, transports fluid and drives emulsification elements (such as shear heads and agitators) to generate shear force, achieving the dispersion and mixing of the oil and water phases. Its performance directly affects the particle size distribution, uniformity, and stability of the emulsion.

[0003] Existing emulsion pumps mostly use fixed shearing elements, which means that the shearing elements (such as rotor and stator structures) cannot be adjusted according to the usage scenario during the emulsification process, and the structure is complex and inconvenient to disassemble and maintain.
