Description
Technical field
The invention belongs to gas engine technical field, be specifically related to a kind of efficient self-adapted gas combustion apparatus of gas engine。
Background technology
Existing gas combustion apparatus is generally adopted pressure reducing regulator and blender composition (venturi or proportion expression), this gas combustion apparatus, combustion gas for steady pressure can mix with air in proportion more accurately after pressure-reduced and-regulated, gas concentration is held essentially constant, and can provide relatively stable gaseous mixture for electromotor。These gas combustion apparatus there is the problem that 1. can not provide air mixture according to the air inlet demand of electromotor, and the efficiency that the direct result caused is exactly mixture combustion reduces；2. inlet air source instability timer can not adjust air demand and air inlet mixing ratio automatically, and the direct result caused shakes exactly or dead fire is shut down；3., for fuel unclean, that dustiness big or quality is not high, conventional apparatus is very sensitive, it is impossible to steady operation, and then causes maximum discharge and high oil consumption。
Summary of the invention
What present invention mainly solves technical problem is that existing gas combustion apparatus can not provide gaseous mixture according to the demand of electromotor, it is impossible to ensure the stability of gaseous mixture。Also solve the supply instability problem of low-rank fuel。
In order to solve above-mentioned technical problem, the present invention provides following technical scheme: the efficient self-adapted gas combustion apparatus of gas engine includes air chamber, pressure regulating cavity, hybrid chamber, Gas Pipe and combination adjustment disk, air chamber connection air intake, hybrid chamber is provided with the gaseous mixture delivery outlet can being connected with electromotor, air chamber and hybrid chamber and opens and closes by combining adjustment disk；Described combination adjustment disk includes diskware, diaphragm, platen, securing member, diskware is rod structure ringwise, diskware upper surface connects the diaphragm maintaining dynamically balanced air pressure, diaphragm isolation pressure regulating cavity and air chamber, the upper surface of diaphragm connects platen, and diskware, diaphragm, platen are fixed as a whole by securing member, and platen upper surface is provided with spring, the other end of spring is provided with regulating part, and regulating part is connected with the cavity wall of pressure regulating cavity；Being provided with in the internal cavities of described diskware and be available for Gas Pipe and the passage that combustion gas enters, passage connects pressure regulating cavity and hybrid chamber；Diskware outer surface and hybrid chamber inwall form the outer wall of the air duct entering hybrid chamber for air, diskware inner surface and Gas Pipe and form the blast tube entering hybrid chamber for combustion gas。
