Liquefied petroleum gas pump is mainly used to transport various volatile liquids and petroleum products with similar properties, such as liquefied petroleum gas, dimethyl ether, chloromethane, ethylene oxide, propane, propylene, butadiene, isobutene, methanol, etc. It is particularly used in liquefied petroleum gas loading and unloading vehicles, steel cylinder filling, workshop feeding and other work occasions. This pump is a positive displacement vane pump with an advanced structure. The stator surface is composed of composite curves, and mechanical seals are used at both ends. Each fixed mating end face is equipped with an "O" - shaped sealing ring, and the rotating mating parts are made of metal corresponding to non-metal, which has the functions of safe and reliable use and multi-purpose.

working principle:

This pump is a positive displacement vane pump, which operates by centrifugal sliding of the blades. The flow rate is related to the shaft speed. The inner surface of the stator is made of a domestically unique composite curve, and the stator, rotor, baffle, and blades form ten sealed chambers. Due to the composite curve of the stator surface, when the rotor rotates, the volume of the inlet chamber gradually increases, and negative pressure is formed to generate suction, thereby sucking in the oil. When the rotor rotates a certain angle, the volume section gradually decreases, and the oil is discharged. There is an oil seal block between the suction chamber and the pressure chamber to separate the suction chamber from the pressure chamber. The blades rely on centrifugal force and two baffle structures to tightly adhere to the inner surface of the stator, allowing the pump to operate normally at rated conditions.
