Description
The utility model relates to a kind of rotor pump, double-arc impeller pump particularly, the rotary piston of its two circular arc camber line shape molded lines, by electric machine main shaft or other powerdriven main shaft drives, in the cylinder body of ogive curve and circular arc camber line combination shape molded lines, rotate, whenever rotate a circle, can finish each twice of the process that sucks liquid in the cylinder body or gas and outer liquid of discharge cylinder body or gas, the highest ideal operation volume is equivalent to 100% of cylinder body volume, the highest ideal operation efficient also can reach 100%, machine volume is little, in light weight, simple in structure, swept volume is big, high working efficiency, the design parameter range of choice is wide, has wide range of applications.
At present, rotor pumps such as three-apexed rotor pump, Bicorn rotator pump and rolling type rotor pump have been had both at home and abroad now.Wherein the three-apexed rotor pump develops from rotary polygonal piston engine, and rotary polygonal piston engine is the myriagram that invention of the fifties Germany in this century; Bicorn rotator pump is the Ren Shijun of the Nanjing of China patent of invention of applying for according to the basic principle of three-apexed rotor pump (Chinese invention patent number 86104412); The rolling rotor pump is the rolling rotor type cold compressor that enterprises such as Chinese Dongfang Machinery Factory, Xi-an and Shanghai freezer compressor head factory develop and produce.Above-mentioned rotor pump exists following shortcoming and problem:
1, complex structure.The three-apexed rotor pump has interior external tooth engagement transmission mechanism and gear, rolling rotor-type pump to be provided with mechanisms such as safety check and camshaft, and then to cause the complexity of structure;
2, swept volume is lower.The swept volume of above-mentioned rotor pump is difficult to reach more than 90% of cylinder body swept volume;
3, working efficiency is lower.The working efficiency of above-mentioned rotor pump is difficult to reach more than 90%;
4, molded lines complexity.The cylinder body of three-apexed rotor pump and Bicorn rotator pump is an epicycloid shape molded lines structure, and rotary piston is the linear molded lines structure of interior envelope, during work, does not have the circular arc cambered surface corresponding to each other, and clearance is hour also the most like this, has brought difficulty therefore for design, manufacturing and detection;
5, sealing problem is bigger.The sealing configuration of Bicorn rotator pump, adopted at two-angle rotor drift angle place two rollers have been installed respectively, when roller rolls along inboard wall of cylinder block, the inboard wall of cylinder block curvature of curved surface constantly changes, and has one section curved surface to approach the plane, when roller contacts with the rolling of inboard wall of cylinder block, the center line that must depart from two-angle rotor, promptly create into the variation of diameter length, therefore not only can influence sealability, the problem of two-angle rotor seizure of piston in cylinder body also may take place.
The purpose of this utility model provides a kind of double-arc impeller pump, can overcome and avoid above-mentioned rotor pump problem, the problem includes: shortcoming and problem, reach the purpose of energy-efficient ground fluid transfer or gas (or pressurized gas), realize extensiveization of the simplifying the structure of this rotor pump, volume miniaturization, weight lighting and Applicable scope.
