YQB Series LPG Pumps

Introduction to YQB Series LPG Pumps

Our manufacturing facility proudly presents the YQB series of liquefied petroleum gas (LPG) pumps, engineered for the efficient and reliable transfer of a variety of volatile liquids. These pumps are specifically designed to handle not only LPG, but also substances like dimethyl ether, methyl chloride, ethylene oxide, propane, propylene, butylene, isobutylene, methanol, and other similar volatile fluids. They are also suitable for refined petroleum products, making them highly versatile. Primary applications for these pumps include the crucial tasks of loading and unloading LPG from transport vehicles, filling gas cylinders, supplying fuel to industrial facilities, and numerous other critical operations where fluid transfer is required.

The YQB series utilizes a positive displacement, rotary vane pump design that incorporates advanced engineering principles. The stator's curvature is meticulously crafted with a complex profile, and a mechanical seal ensures a secure seal at both ends. All stationary interfaces are fitted with O-rings, providing an added layer of sealing integrity. For the rotating parts, a combination of specific metals and non-metallic materials is employed, guaranteeing robust performance, operational safety, and versatile capabilities.

Operational Principles of LPG Pumps

The core principle of these pumps is their positive displacement mechanism. Operation relies on the centrifugal sliding motion of the vanes, with flow rate directly proportional to the shaft's rotational speed. The pump's stator features a complex internal curvature, and the arrangement of the stator, rotor, baffles, and vanes creates a series of ten sealed chambers.

As the rotor rotates, the volume within the intake chamber gradually increases due to the specific complex curvature of the stator. This expansion generates a vacuum, facilitating the suction of fluid into the pump. As the rotor continues its rotation, the volume of this section steadily decreases, resulting in the hydraulic discharge of the liquid. A strategically placed oil block is incorporated between the intake and discharge chambers, effectively isolating these areas. The vanes are pressed firmly against the inner curve of the stator by a combination of centrifugal force and two pressure baffles. This ensures stable and reliable pump performance under the intended operational conditions.
