YQB series liquefied petroleum 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.
The LPG gas pump type is a positive displacement vane pump. The work relies on the centrifugal sliding of the blades. The flow rate is related to the speed of the shaft. The inner surface of the stator is made of a composite curve created in China. The stator, rotor, baffle, and blades form ten sealed cavities. The curved surface of the stator is a composite curve. When the rotor rotates, the volume of the inlet cavity gradually increases, and negative pressure is formed to generate suction, thereby sucking in the oil. When the rotor rotates for a certain angle, the volume section gradually decreases, so that the oil is discharged. There is an oil block between the oil suction cavity and the oil pressure cavity to separate the oil suction cavity from the oil pressure cavity. The blades rely on centrifugal force and two baffle structures to closely fit the inner curved surface of the stator, so that the pump can work 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.
