Automatic deflation equipment of turbo-charging system of medium speed diesel engine

Abstract

The invention discloses an automatic discharge device of middle-speed diesel boosting system, comprising a discharge valve with hollow chamber and an air inlet through to the air inlet tube of diesel engine, a discharge valve in the chamber of discharge valve and near one side of air inlet to sliding along the chamber, a hollow limiting valve screw plug at another end, and a limiting spring between the discharge valve and the limiting valve screw plug. The discharge valve at the outer end of the limiting valve screw plug is arranged with a limiting valve locking cap; the air inlet of the discharge vale is connected to the sealing end cover fixed with the air inlet tube of diesel engine; the axial interface between the sealing end cover and the discharge valve is arranged with a sealing ring. The invention has simple production, small volume, and low cost, while it can improve the low-speed large-torsion property.

Description

technical field [0001] The invention relates to an automatic deflation device for a supercharging system of a medium-speed diesel engine. Background technique [0002] In diesel engines for fishing trawlers, users often use the low-speed and high-torque operating conditions of diesel engines, so optimizing such diesel engines according to the traditional propulsion-specific operating conditions cannot fully meet the requirements of such users. Although the use of high-speed turbine-end bleed air in high-speed vehicle diesel engines has become popular, but because medium-speed diesel engines have relatively large bleed valves, problems are prone to occur at high temperatures. Therefore, the structure of the venting device for medium-speed diesel engines under high operating conditions has always been complicated, and the manufacturing cost is high, and turbochargers for medium-speed diesel engines with high operating conditions and venting are seldom manufactured in China. ...

AI Technical Summary

Problems solved by technology

[0002] In diesel engines for fishing trawlers, users often use the low-speed and high-torque operating conditions of diesel engines, so optimizing this type of diesel engines according to the traditional propulsion characteristic operating point can no longer fully meet the requirements of such users

Although the use of high-speed turbine-end bleed air in high-speed vehicle diesel engines has become popular, but because medium-speed diesel engines have relatively large bleed valves, problems are prone to occur at high temperatures

Therefore, the structure of the venting device for medium-speed diesel engines under high operating conditions has always been complicated, and the manufacturing cost is high. Moreover, turbochargers for medium-speed diesel engines with high operating conditions and venting are rarely manufactured in China.
