Eccentric shaft type translational rotor pump and engine

Abstract

An eccentric shaft type translational rotor pump and engine comprises a first eccentric shaft, a second eccentric shaft, a rotor and a cylinder body; the first eccentric shaft and the second eccentricshaft are the same in eccentric distance, in addition, a first eccentric shaft first shaft and a second eccentric shaft first shaft can be rotationally arranged on the cylinder body, and a first eccentric shaft second shaft and a second eccentric shaft second shaft can be rotationally arranged on the rotor; the rotor or / and the cylinder body is provided with a rotor groove or / and cylinder body groove, a slide sheet can slide in the rotor groove or / and cylinder body groove, and the slide sheet is in jointing sealing with the outer wall surface of the rotor or the inner wall surface of the cylinder body so that the spaces, located on the two sides of the slide sheet, of the rotor and the cylinder body can be isolated; meanwhile, the inner space located between the rotor and the cylinder body is divided into two independent spaces through the zone where the outer wall surface of the rotor is in jointing sealing with the inner wall surface of the cylinder body; and the volume of the two independent spaces is subjected to periodical change along with rotation of the rotor.

Description

technical field [0001] The invention relates to positive displacement pumps and engines, especially vacuum pumps, compression pumps, air compressors, blowers, gas delivery pumps, liquid delivery pumps, liquid booster pumps, turbochargers, gas turbines, internal combustion engines, engines, steam turbines, Gas turbines, hydraulic turbines, pressure turbines, metering pumps and other fields, have the characteristics of high compression ratio, small clearance volume, simple structure, easy processing, low vibration and noise, stable and reliable, etc. Background technique [0002] The positive displacement pump mainly uses the change of the volume of the cavity to inhale and extrude the fluid, and at the same time completes the energy conversion process, such as a liquid turbine or a gas turbine device that converts the kinetic energy and potential energy of the fluid into mechanical energy. Existing slide valve pumps with large volume and vibration are mostly used in low-speed...

AI Technical Summary

Problems solved by technology

[0003] The technical problem mainly solved by the invention is to reduce the volume of the mechanical device on the premise of reducing the manufacturing difficulty of the existing positive displacement pump and improving the working stability and service life, which is suitable for high-speed working conditions and obtains a very small clearance High-performance sealing is realized on the basis of the volume, and the fluid inlet and fluid outlet do not need check valves to work, which can greatly reduce the vibration and noise of the mechanical device
