Description
Technical field
The utility model relates to a kind of gas engine compressor apparatus with turbosupercharger, particularly a kind ofly is applied to be the turbocharger compressor apparatus for compressing inflammable mixture gas of fuel, to belong to gas supercharging of internal combustion engine field with biogas, methane gas etc.
Background technique
Turbosupercharger is that the exhaust energy that utilizes motor to discharge drives turbine, and the drive compressor impeller high speed rotating coaxial with turbine, fresh air is compressed the cylinder that enters motor under the compressor impeller action of centrifugal force, thereby increased the aeration quantity of motor, can supply more fuel oil perfect combustion, thereby the power of motor, the consumption of having saved fuel oil have been improved, simultaneously because the improvement of combustion condition has reduced CO in the waste gas, HC, NO
XAnd the discharging of harmful substance such as PM, reduced the noise of motor.Along with the variation of motor fuel, be that the gaseous fuel of representative relies on advantages such as self is cheap, combustion cleaning to form the batch process scale gradually with rock gas, coal gas etc., the gas engine supercharging technology is also progressively used in engine works.But at present the gaseous fuel that adopts all be can storage of higher pressures gas, the clean air of the still simple compression of the turbosupercharger that adopts in the motor, gaseous fuel is controlled by closure, in engine cylinder with supercharging after air mixing burning, belong to mixed combustion in the machine.Yet, inflammable gas for picture biogas, gas one class, because production approach problem, can't centralized high voltage store, when so supercharged engine acts as a fuel with the type gas, inflammable gas need mix at external engine, sends into motor then after the turbosupercharger compression, thereby realizes the purpose of supercharged engine hoisting power.
Directly the turbosupercharger of compressing inflammable mixture gas body and function is the total member on the type gas engine, inexorable trend along with engine booster, the motor that satisfies direct compressed biogas class burning mixture becomes the problem of research with pressurized machine, and the domestic product that does not have to satisfy this demand on the stricti jurise comes out.
At present, the biogas of exploitation, methane gas class motor do not adopt supercharging technology because of approach and storage problem that fuel produces both at home and abroad.Along with of the lifting of gas engine producer, directly also stepped into regular to the research of the turbocharger arrangement of burning mixture compression to the supercharged engine demand.The gas compressor of known turbosupercharger comprises compressor impeller (1), compressor casing (3) and gas diffusion passage (4) three parts as shown in Figure 1.Under the normal working, compressor impeller (1) high speed rotating under the drive of turbine rotor (6), from compressor air inlet machine mouth (2), suck clean air and carry out centrifugal compression, high-speed gas after the compression enters gas diffusion passage (4) from compressor impeller outlet (5), enters motor after collecting by compressor casing runner (7) then and participates in burning.Compressor impeller (1) and compressor casing (3) are aluminum alloy material, and matching gap is about 0.5mm, with the blade normally rotation in the process of pressurized gas that guarantees compressor impeller (1).When frequent improper ato unit of user or engine fuel system etc. broke down, wearing and tearing can appear in pressurized machine internal bearings system, caused compressor impeller and compressor casing that shell takes place to wipe after the wearing and tearing accumulation, produced spark.Therefore, need the compressor apparatus of a kind of compressing inflammable mixture gas of design, solve pressurized machine and after damage, may produce the fault that spark sets off an explosion with turbosupercharger.
The model utility content
Problem to be solved in the utility model provides a kind of turbocharger compressor apparatus for compressing inflammable mixture gas, do not produce naked light in the time of can guaranteeing the collision of compressor impeller and compressor housings, reduce local temperature simultaneously, thereby satisfy the needs of the direct compressing inflammable mixture gas body of pressurized machine.
