Technical field
The utility model relates to a kind of pick-up unit, is specifically related to a kind of reliability pick-up unit of vehicle engine exhaust gas recycle valve.
Background technology
Exhaust gas recirculation (EGR) system is meant that the part waste gas that motor car engine is discharged is transmitted back to inlet manifold, and enters cylinder once more with incoming mixture.Owing to contain a large amount of CO2 in the waste gas, and CO2 can not burn and absorbs a large amount of heat, the temperature of combustion of combination gas in the cylinder is reduced, thereby reduced the growing amount of NOx, vehicle engine exhaust gas recycle valve (EGR valve) is a kind of control device that is used to control exhaust gas recirculation (EGR) systemic circulation.Because vehicle engine exhaust gas recycle valve (EGR valve), its working environment is more abominable usually and harsh, therefore for guarantee vehicle engine exhaust gas recycle valve (EGR valve) can be under abominable and rigorous environment reliably working, must make detection to the reliability of vehicle engine exhaust gas recycle valve (EGR valve), but lack corresponding general checkout equipment in the market.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of reliability pick-up unit of vehicle engine exhaust gas recycle valve, this pick-up unit can be made detection to the reliability of vehicle engine exhaust gas recycle valve (EGR valve), meets consumers' demand.
For achieving the above object, the utility model provides a kind of reliability pick-up unit of vehicle engine exhaust gas recycle valve, comprise environmental cabinet, air compressor, air setting device, wind circulating device, be provided with the airtight generation chamber that can be used for detecting the vehicle engine exhaust gas recycle valve in the described environmental cabinet, described air compressor, air setting device, wind circulating device are communicated with airtight generation chamber, also are provided with evaporator, well heater, humidifier in the described airtight generation chamber.
The utility model can further be set to be provided with water storage tank in the described airtight generation chamber, also be provided with sealing chamber resettling on the described environmental cabinet, water storage tank links to each other with sealing chamber resettling, described air compressor and air setting device all are positioned in the sealing chamber resettling, also are provided with drainpipe and overflow vent in the described sealing chamber resettling.
The utility model also can further be set to also be provided with the stationary installation that is used for fixing the vehicle engine exhaust gas recycle valve in the described airtight generation chamber, and described stationary installation comprises specimen holder and adjustable glove support.
The utility model also can further be set to described environmental cabinet and be provided with instrument connection and the view window that is communicated with airtight generation chamber.
The utility model also can further be set to described environmental cabinet and also be provided with broken-circuit controller outward, and described evaporator, well heater, the humidifier of being located in the airtight generation chamber all is connected with broken-circuit controller.
The beneficial effects of the utility model are: adopt said structure, vehicle engine exhaust gas recycle valve to be measured (EGR valve) is placed on the interior specimen holder of airtight generation chamber, be positioned at the evaporator of airtight generation chamber by broken-circuit controller control and adjusting, well heater, humidifier, make the environment temperature in the airtight generation chamber be controlled at-40 ℃～125 ℃, come the operating temperature range of simulated automotive part, open air compressor again, the air setting device, the wind circulating device makes the environment in the airtight generation chamber that various variations take place, come the reliability that is positioned at airtight generation chamber vehicle engine exhaust gas recycle valve (EGR valve) is made detection and evaluation by instrument connection and view window, satisfy the reliability detection demand of user the vehicle engine exhaust gas recycle valve.
