An electric heating system to replace high temperature gas in turbocharger test

Abstract

An electric heating system for replacing high-temperature gas in a turbocharger test, characterized in that it includes: an electric heater (group) (6), a power regulator (group) (11), a power regulating cabinet (10), a flow meter (2), regulating valve (group) (3), etc. By using the electric heating system to generate high-temperature gas, it replaces the traditional high-temperature gas to impact the turbine to do work and drive the supercharger to run. Compared with the traditional method, the electric heating system of the turbocharger test of the present invention has the advantages of simple system, safety and reliability; clean and pollution-free, and will not overheat and burn out the turbine; the temperature stability of the turbine inlet is high, and the accuracy of temperature regulation is also high. Higher; wider flow and turbine inlet pressure adjustment range, higher precision; longer life, convenient use and maintenance, high economy and many other advantages.

Description

technical field [0001] The invention belongs to the technical field of turbocharger tests, and in particular relates to an electric heating system to generate high-temperature gas to replace the high-temperature gas in the turbocharger test to impinge on a turbine. Background technique [0002] In the prior art, the test of a turbocharger for automobile or aviation is to use a gas generator to generate high-temperature gas through combustion to simulate engine exhaust for impinging on the turbine and driving the supercharger to run. The disadvantages of this scheme are: the pressure or flow of gas is difficult to control, and the controllable range is narrow; the stability of combustion is not high, and the temperature of gas entering the turbine is difficult to control accurately; the gas generated when the gas generator is ignited may exceed Due to insufficient combustion, the gas will inevitably contain impurities such as carbon particles and oil stains, which will remain...
