In order to achieve the above object, the technical solution of the utility model: the low pressure and mass flow liquid pump, form by rotor, transmission shaft, stator, rotation blade, moving blade, oil distribution casing, spring; Rotor, stator, rotation blade, moving blade constitute displacement-variable device, it is characterized in that, described rotor is connected with transmission shaft, rotation blade is installed on the rotor, stator is connected with oil distribution casing, moving blade is installed on the stator, and spring and moving blade link, and transmission shaft is installed on the oil distribution casing.
The said stator internal surface is the cylinder type cavity, and rotor is the eccentric wheel that outer surface is surrounded by compound curve.
Said stator internal surface, rotor outer surface, rotation blade, moving blade, oil distribution casing end face form a sealed volume.
Above-mentioned moving blade divides sealed volume into two-part, and the volume of every part cavity volume changes in the rotor operation process, and when sealed volume changed from small to big, fluid was inhaled into the pump housing, and cavity volume is from large to small the time, and fluid is discharged from the pump housing, finishes pumping function.
Above-mentioned displacement-variable device can adopt two displacement-variable devices, and the structure of the 180 ° of coaxial parallel connections of phase place that interlace starts dead point and pulsation to eliminate; Also can adopt the coaxial interlock of one or more displacement-variable device to install, form the fluid mixing pump of one or more output.
The beneficial effects of the utility model: highly versatile: with simple cavity volume delete the combination just can form another type, derivatives are more, using scope is extremely wide, can work as water pump, also can work as oil pump, mixing pump, but the application parameter random fluctuation of product; Easy to maintenance: wear automatic-compensation, lower to the fluid requirement of carrying, it is simple and convenient that maintenance recovers precision; Cost is low: number of spare parts is few, and part processing precision is low, and processing technology is simple; The volumetric efficiency height of pump, oil pump capacity is big in the unit time.
