Abstract
The invention provides a two-angle-rotor blower which is an apparatus using volumetric changes caused by rotation of an oval rotor in a cylinder body to realize air discharge. The two-angle-rotor blower has the characteristics of a simplified structure, high efficiency, energy conservation, a small size, smooth and reliable operation, low vibration noise, a long service life, etc. Compared with a Roots blower and a centrifugal blower, the two-angle-rotor blower provided by the invention can save more than 15% of energy. As a brand new application technology, the two-angle-rotor blower is bound to bring immense economic benefits and social benefits in related applied industries like solar power generation, exploitation of coal and minerals and iron and steel smelting due to the comprehensive advantages of high efficiency, low energy consumption, low operating cost and multiple uses, especially protruding performance in energy conservation and consumption reduction, of the two-angle-rotor blower, and the two-angle-rotor blower has wide application prospects.
Description
Technical field
The invention belongs to the blower fan field, particularly a kind of design implementation method of oval two-angle rotor blower fan.
Background technique
Blower fan classification can be by the direction of gas flow, is divided into the types such as centrifugal, axial flow, diagonal flow type (mixed-flow) and cross-flow type.Centrifugal blower is that air stream axle mainly radially flows behind the impeller that enters blower fan, and this class blower fan is made according to the principle of centrifugal action, and product comprises centrifugal blower, centrifugal blower and centrifugal compressor.The air-flow of axial-flow blower is the impeller that axially enters blower fan, flows along axial direction on barrel surface approx.This class blower fan comprises propeller fan, axial flow blower and axial flow compressor.The revolution blower fan is to utilize rotor to change gas chamber volume to carry out work, and common kind has Roots blower, rotary compressor etc.
Blower fan is very widely engineering goods of purposes, the underground engineerings such as mine, subway, underground generating; The chemical industry such as petrochemical industry, daily use chemicals all is the application of blower fan, and the application of blower fan almost relates to the every field of national economy.Motor with matched with blower in all kinds of machineries of China's all trades and professions and electrical equipment accounts for 60% of national motor installation amount, consumes electric energy and accounts for 1/3rd of whole nation generating total amount.According to the nineteen ninety incomplete statistics, about 4,000,000 of the owning amount of national blower fan, about 2,850,000 of using.These blower fans overwhelming majority adopts motor driving, have the title of electricity-eating tiger, thereby the energy-conservation tool of blower fan is of great significance.
Summary of the invention
The present invention relates to a kind of oval two-angle rotor blower fan, mainly by comprising oval two-angle rotor, cylinder body, interior external gear, eccentric shaft, support shoulders, support shoulders ring, bearing, balancing weight, front and rear cover, the compositions such as porting.The molded line of two-angle rotor is elliptical shape, and the molded line of cylinder body is rotor theory shaped wire envelope curve line.External gear is fixed on the end cap, and internal gear is fixed on the two-angle rotor, and external gear is 1: 2 with internal gear number of teeth ratio.Cylinder body and two-angle rotor surface are provided with seal ring in the contacting point forever, and pump chamber is divided into two working rooms.Between oval rotor end-face and front and rear cover, be provided with seal ring.On cylinder body or front and rear cover have the inlet and outlet mouth.Whole in operation, for smooth running, at the two-angle rotor two ends lightening hole is arranged, and at the eccentric shaft two ends balancing weight is installed and carries out counterweight.
The two-angle rotor blower fan is the fluid machinery of positive displacement, and the gas pressure of its output is high and relatively constant, and the pressure surge that is not exported affects, and this is that the pump machine series products such as centrifugal, axial flow is incomparable.The two-angle rotor blower fan is a kind of of scavenged area maximum in the rotary piston machine series products, has high energy-conservation, little vibration, low noise, little, lightweight, the rotating speed high of volume, and this is that other pump machine products are incomparable.Low cost of manufacture is easy to produce, and has wide market prospects space.
Description of drawings
Fig. 1 is two-angle rotor blower fan schematic representation.1. external gear, 2. internal gear, 3. oval two-angle rotor, 4. cylinder body, 5. eccentric shaft, 6. eccentric wheel.Two-angle rotor 3 is housed in the pump housing, and eccentric shaft 5 is installed on the eccentric wheel 6, and eccentric wheel 6 and two-angle rotor 2 are installed together.
Embodiment
Working procedure is as follows: when transmission shaft rotates, external gear is fixed on the end cap, internal gear and external gear engagement, and eccentric wheel drives internal gear and two-angle rotor is done planetary motion around external gear, eternal and the two-angle rotor Surface Contact of pump housing point is divided into two working rooms with pump chamber.Two-angle rotor continuously rotates, and makes the swept volume of a single chamber cyclically-varying, can realize continuous air extraction and exhaust.The relative pump housing of rotor circles and carries out suction and discharge.Pump shaft revolves and turns around, the rotor half-turn.This low rotational speed reduces vibration and increases working life.The distance of rotor quality and gyration center is definite value, and the eccentric mass of two-angle rotor machine can be balanced.
