Pressurizer for centrifugal fan

Abstract

The invention provides a pressurizer for a centrifugal fan, and aims at solving the problems that the air feeding quantity can be increased by the existing exhaust turbine pressurizer, but the exhaust cannot be discharged smoothly after combustion; exhaust turbine blades at the high temperature more than 600 DEG C for a long time are deformed, fall down and damaged. The pressurizer for the centrifugal fan is high in lubricating performance of a crankshaft, and extremely small in axial and radial gaps; the outputted power directly drives an impeller of the pressurizer to forcibly increase the air feeding power of an engine by flow concentrating of a turbine housing to achieve pressurizing. The pressurizer for the centrifugal fan is that the impeller of the fan and a flywheel of the engine are integrated; the engine pressurizer is changed from the original auxiliary device into the normal device of the engine; a pressurizing device is provided for each engine to achieve reasonable combustion; the efficiency can be increased; the energy can be saved; the carbon discharge can be reduced; the attached figure in the abstract is shown in figure 1; (1) is the turbine housing, (2) is the original magnetic motor positioning step, (3) is the crankshaft, (4) is the impeller, (5) is the flywheel, and (6) is the cylinder body in the figure.

Problems solved by technology

[0003] All of them have been in a state of overload for a long time. For example, the load of a single-cylinder small four-wheel transport tractor is 4-8 tons, which is equivalent to the load of a Jiefang car in the 1960s and 1970s. A four-axle truck can The load is 40-50 tons... So the place they pass is a string of black smoke, which is the result of a reasonable ratio of combustion. How to give full play to the fuel efficiency of a diesel engine has been explored and practiced for many years. A late-stage remedial measure, how to increase the intake air volume of a diesel engine that has been finalized is also one aspect of the remedial measures. Exhaust gas turbocharging is commonly used now. Although this method increases the intake air volume, it also hinders the combustion after combustion. The smooth removal of exhaust gas has become a great regret for the exhaust gas turbocharger! The working principle of the exhaust gas turbocharger: directly see that the displacement and intake air volume of a diesel engine are equal, and the exhaust gas removed by it drives the worm gear, and the exhaust gas worm gear drives the intake worm wheel blades to generate power to drive air into the cylinder. Perpetual motion machine, but it still has a certain effect in the actual production and application process. The effect comes from the sharp reduction of the space above the cylinder in the exhaust stroke of the piston, so that the exhaust gas is compressed, and the compressed exhaust gas is the power of the turbocharger. During this period of force transformation, the engine becomes an air compressor and consumes energy. The consumption of this physiological function is like when we climb a mountain wearing a mask and climbing a mountain without a mask will produce completely different physiological effects. It is very easy for a healthy person to walk with a travel bag on his back, but a person with a lung disease has to walk a few steps and stop when he walks empty-handed... The same is true for machinery, so the current working method of the exhaust gas turbocharger is not advisable!

[0004] Working conditions of the exhaust gas turbocharger: the exhaust gas turbocharger generally works at a temperature above 600°C. If the oil supply system fails and causes fuel oil to burn sluggishly, the exhaust temperature will rise sharply, burning the impeller blades, causing the blades to fall off and completely Loss of function, in this case the supercharger is useless, this working condition is not available

[0005] In addition, the currently reported belt turbocharger and air wave supercharger have no similarities with the centrifugal fan supercharger from the current market share, so no comment will be made here.
