The glass lifter, also known as the window regulator or lifter, uses a motor to drive the glass lifter to drive the glass up and down along the slide rail to realize the lifting and lowering of the glass. It is mainly used to reduce the air resistance of the car and has the functions of shielding, sealing, heat insulation and sound insulation. It is also an important part of the overall shape of the car.
The electric glass lifter for vehicles is composed of motor, reducer, guide rope, guide plate, glass mounting bracket, etc.The lifting glass for vehicles is mainly driven by a motor. In order to ensure driving comfort and driving safety, the motor needs to have good performance.Air tightness。
What I’m sharing today is aboutAir tightness tester for automotive glass lift motorscase.
Testing equipment: HC classic series air tightness detector
According to the product shape, structure and customer needs, corresponding jigs and tooling are customized.
Use the direct detection method, select the set program, press the device start button, and the instrument starts detection.Inflation 20Kpa, time 5 seconds, stabilization time 5 seconds, test time 5 seconds.If the leakage value does not exceed 30pa during the test, it means that the product under test is a qualified product, otherwise it is a defective product.
● High precision
Powerful 32-bit processor and 24-bit A/D converter, coupled with the patented "intelligent pressure difference" algorithm, the test accuracy is equivalent to that of the differential pressure type.Compared with the differential pressure type, the testable leakage range is larger, which is basically equal to the test range.
● AI algorithm
The automatic learning function can identify the characteristic information of the sample to be tested, analyze the valid data of the sample information, automatically judge and identify the critical point of the leakage volume, and obtain the optimal process time parameters through the analysis of the critical value, which greatly improves the difficulty of getting started with the instrument for the first time.
●Powerful testing function
The system comes with 2 pressure forms and 8 basic judgment methods, which can be combined into more than 20 test functions to easily cope with various working conditions and meet your various requirements!
●Stable, reliable, improve efficiency
Built-in self-developed patented technology, "IVT" pneumatic sealing valve island; greatly improves test accuracy and speeds up inflation. At the same time, large leaks have been detected during the inflation stage, saving the entire test time.
●The test process is simple and more versatile
There is no need for standard parts, no need to make two sets of jigs, no need to compare with standard parts, and elimination of deformation errors after multiple tests of standard parts.
●More scalable
Modular design allows one host to control an execution module composed of multiple full-function valve islands according to requirements.Realize full-featured multi-channel testing including positive and negative pressure and indirect testing.
