Quick Detail

The YQB series of liquefied petroleum gas pumps produced by our factory are mainly used to transport liquefied petroleum gas, dimethyl ether, methyl chloride, ethylene oxide, propane, propylene, butadiene, isobutylene, methanol and other olatile liquids with similar properties. And petroleum products, especially for LPG loading and unloading trucks, cylinder filling, workshop feeding and other work places. The pump is a volumetric vane pump with advanced structure.The stator curved surface is composed of a composite curve. The two ends are mechanically scaled. The fixed-fit end faces are all made of "O"-type sealing ring. The rotating moving parts are made of metal corresponding non-metal. It has the function of safe and reliable use and multi-purposeuse.

The pump type is a positive displacement vane pump, the work is driven by the blade centrifugal sliding, the flow rate is related to the rotational speed of the shaft, the inner curved surface of the stator is made of a composite curve, and the stator and the rotor, the baffle and the vane are composed of ten sealed cavities, because the stator curved surface is The compound curve, when the rotor rotates, the volume of the inlet chamber gradually increases, and a negative pressure is generated to generate suction, thereby sucking the oil. When the rotor rotates at a certain angle, the volume section is gradually reduced, thereby hydraulically discharging the oil, in the oil suction chamber and An oil block is placed between the oil pressure chamber to separate the oil suction chamber from the oil pressure chamber. The blade is closely attached to the inner curved surface of the stator by centrifugal force and two baffle structures, so that the pump works normally under the rated condition.
