A pump is a machine that delivers or pressurizes a fluid. The pump is mainly used for conveying liquid such as water, oil, emulsion, suspoemulsion and liquid metal, and can also be used for conveying liquid, gas mixture and liquid containing suspended solid. Pumps can be generally classified into three types, namely, positive displacement pumps, power pumps and other types of pumps according to the working principle, and can be classified and named according to other methods besides the working principle, for example, the pumps can be classified into electric pumps, hydraulic pumps and the like according to the driving method; can be divided into a single-stage pump and a multi-stage pump according to the structure; can be divided into a boiler feed pump, a metering pump and the like according to the application; the liquid can be divided into a water pump, an oil pump, a slurry pump and the like according to the property of the transported liquid. According to the structure of no shaft, a linear pump and a traditional pump can be divided, and the water pump can only convey material flow taking fluid as a medium and cannot convey solids.
The gear pump is a rotary pump which can transfer liquid or pressurize it by means of the change and movement of working volume formed between pump cylinder and meshed gear, and is formed from two gears, pump body and front and rear covers, when the gears are rotated, the volume of space of gear disengagement side is changed from small to large, and formed into vacuum to suck liquid, and the volume of space of gear meshing side is changed from large to small to squeeze liquid into pipeline, and the suction cavity and discharge cavity are separated by means of meshing line of two gears, and the pressure of discharge outlet of gear pump is completely dependent on the resistance of pump outlet.
Current gear pump structure function singleness can't realize the acceleration action to rivers, consequently, designs a gear pump and is imperative.
SUMMERY OF THE UTILITY MODEL
