"T" is a good thing, is there a car?
"T" is a good thing, is there a car? Looking at the entire automotive market, Turbo Boost is becoming a mainstream trend. All types of cars, all with a "T". It seems that there is a "T" at the rear of the car, and it will appear to be higher, and in fact it is.
Compared to naturally aspirated engines, turbocharged engines have more powerful engine power output in terms of power performance. At the same time, the displacement can be reduced, and the fuel burning ratio is increased to some extent.
The typical 4-cylinder turbocharger is rated at 130,000-150,000 rpm, the average turbine engine can reach 600 °C shortly after start-up, and the turbine using AGV technology will produce 1000 °C high temperature, Bugatti The maximum temperature of the dragon's four-turbine engine can exceed 1600 °C.
The current strong market demand for turbochargers and the high speed and high operating temperature of the turbocharger impose demands on equipment manufacturers for production cycle improvement, assembly precision and high stability.
The turbocharger is a core component, and its importance in improving engine efficiency is self-evident. Key components such as oil pumps, OCV valves, and EGR coolers associated with superchargers are also indispensable.
Oil pump
When the engine is running, in addition to lubricating other components, the oil pump lubricates the turbocharger shaft through the oil passage to deliver low-temperature lubricating oil to the turbine bearing to take away the heat of the turbine.
OCV valve
The OCV valve changes the flow direction and flow rate of the oil in the oil passage, and adjusts the timing angle of the camshaft to adjust the amount of intake (exhaust) and valve opening and closing time.
EGR (discarded recycling system)
EGR and turbochargers are the two flow directions of the exhaust portion of the engine. Once EGR is turned off, the pre-vortex pressure increases and the turbine speed exceeds the safe upper limit, which reduces the life of the supercharger.
The parts assembly line of the above oil pump, OCV valve and EGR system are the same as the supercharger production line, which has high requirements for production cycle and assembly precision.
Looking at the current auto parts market, it is basically monopolized by foreign capital. Component assembly testing technology is the core technical threshold. In Hangzhou, there is such a high-end equipment localization as the auto parts intelligent manufacturing system integrator - Hangzhou Gaopin Automation Equipment Co., Ltd., has formed a complete assembly test solution in the field of automotive parts assembly testing, its turbo increase The pressure gauge assembly line has occupied 80% of the national market share.
Hangzhou Gaopin automated assembly and test line, stand out among the domestic counterparts, can not be separated from the following advantages. Take the turbocharger assembly line as an example:
(1) steady
High-quality MES2.0 system management, monitoring and assembly process.
136 items are equipped with error proofing to eliminate the process problems that may arise during the assembly process. The high-quality EOL test equipment can detect quality defects that cannot be detected 100% in the production process.
(2) fast
The industry-leading assembly cycle, the assembly of a turbocharger takes only 60 seconds. The fully automated assembly of the supercharger core has been achieved.
(3)
The detection accuracy of the pre-leaf gap and vortex front clearance is accurate to: 0.01mm (equivalent to the smog particle diameter of pm10)
Product assembly pass rate" 99.99%
A good car, the "T" is not enough. The pump/oil pump/vacuum pump, VVT phaser, EPS power steering, i-Booster booster, sensor and other 10 million parts together form a complete car. The accuracy, quality reliability and stability of these parts are guaranteed by the auto parts assembly test equipment vendors such as high-quality automation.
There are more and more T-cars on the road, and cars with T are getting more and more fuel-efficient. The hero behind the scenes is constantly striving for the localization of the core technology of the component assembly line.
