YQB series lpg gas pump is a positive displacement vane pump with advanced structure. The curved surface of the stator is composed of composite curves. Both ends adopt mechanical seals. Each fixed and mating end surface adopts an "O" seal ring. The rotating parts adopt metal corresponding to non-metallic parts. It has the function of safe and reliable use and multi-purpose in one machine.
Liquefied petroleum gas (LPG) filling pumps are positive displacement vane pumps that operate on the principle of centrifugal sliding of the vanes. When the rotor rotates, the volume of the inlet chamber gradually increases, creating a vacuum that generates suction and draws in the liquid. When the rotor rotates to a certain angle, the volume gradually decreases, forcing the liquid out. The blades rely on centrifugal force and two baffle structures to tightly adhere to the inner curved surface of the stator, enabling the pump to operate normally under rated conditions.
YQB series lpg transfer pumps are mainly used to transport various volatile liquids and petroleum products with similar properties, such as:
①liquefied petroleum gas
②dimethyl ether
③methyl chloride
④ethylene oxide
⑤propane
⑥propylene
⑦butadiene
⑧isobutylene
⑨methanol
It is especially used in working occasions such as loading and unloading trucks for liquefied petroleum gas, filling steel cylinders, and feeding workshops.
