Different oil pressure, amplitude and frequency can be set through the tensioner comprehensive performance test equipment to verify the settlement performance, damping performance, dynamic damping performance and actuation durability of the tensioner.
The front engine is driven by the rear motor to simulate the normal operation of the engine. At the same time, the durability of VVT, tensioner and timing system are tested to verify the reliability of product development. Through process tracking and comparison of pre and post test data, it can escort the design reliability and quality stability of the product.
Through the VVT/OCV comprehensive performance test equipment, you can detect the performance of the product, get a certain understanding of the performance of the product under test, monitor the performance of the product under test, and find out the potential performance bottlenecks, analyze and optimize them through capability verification, planning capability, performance tuning, defect discovery and performance benchmark comparison.
Check the lock pin clearance, starting pin pressure, driving torque, response time, adjustment angle, friction, leakage and other performances of VVT, and check the flow characteristic curve, center point duty cycle, hysteresis curve and other performances of OCV.
The one-way valve is the most important part of the tensioner. In Kaili, each individual one-way valve will undergo 100% air tightness test to meet its performance requirements. At the same time, the one-way valve assembly pressed into the tensioner housing will also be tested for 100% air tightness in professional equipment to ensure that each installed semi assembly part is in the best performance state.
Through professional endurance test equipment, carry out continuous endurance test for OE parts and self-made parts for more than 500 hours to simulate the continuous opening and closing of VVT during the actual operation of the engine, so as to test the quality stability and reliability of the product.
Through professional durability test equipment, the samples will be continuously tested for more than 500 hours, so as to compare their performance, and simulate the working state of the tensioner that vibrates continuously during the actual operation of the engine, so as to test the quality stability and reliability of the product. At the same time, it can test the actuating life and dirty oil resistance of the tensioner.
During the test, the temperature, humidity, vibration (high or low temperature), (sinusoidal vibration or random vibration) and electrical stress are comprehensively applied to the samples in the same climate test chamber according to the specified cycle to conduct the "environmental simulation" test of temperature, humidity and vibration. Compared with a single environmental factor, it can more truly simulate the product transportation and actual use environment, and fully consider the requirements of different working conditions in the design.
Kaili environmental testing laboratory includes precision oven, high and low temperature alternating test chamber, high and low temperature alternating damp heat test chamber, three chamber cold and heat shock test chamber and salt spray test chamber. It can test the reliability of plastic, rubber and other industrial products at high and low temperatures. The three box cold and heat shock test box is a necessary test equipment for the metal, plastic, rubber, electronic and other material industries. It is used to test the extent to which the material structure or composite material can withstand the continuous environment of extreme high and low temperatures in an instant, It can detect the chemical change or physical damage caused by thermal expansion and cold contraction of the sample in the shortest time. The salt spray test chamber is applicable to the salt spray corrosion test of parts, electronic hardware components, protective layers of metal materials and industrial products.
We have provided a special flexible production line for the R & D and sample of new products to ensure that the products are in the best efficiency in the R & D and trial production process.
