Automobile assistant pump steering LR029184 oil pipe profession also suffered a certain impact. The whole automotive tubing industry upward trend is blocked, most of the enterprises production cuts. 2009, the automotive tubing LR032884 enterprises have been utilizing automation control technology, the beginning of the production equipment and production process renewal and transformation, some enterprises of the automotive tubing key processes for automated monitoring and control, and some enterprises to build a fully automated control of the production line, which on the improvement of automotive tubing LR044590 product quality plays an important role. The research report pointed out that the automotive fuel line LR057239 as a loss parts, even if the vehicle supporting demand cuts, but the huge automotive aftermarket will maintain a relatively stable demand, when foreign parts buyers and distributors consume the inventory, or to continue to purchase, therefore, the automotive fuel line export shopping malls in the experience of the first few months of the doldrums, and then gradually began to pick up. From the beginning of 2009, the automotive fuel pipe export orders began to pick up gradually, most of the automotive fuel pipe enterprises have returned to normal production, part of the enterprise shopping mall demand and even better than the same period last year.
Automobile fuel pipe and fuel tank, if the automobile fuel pipe is out of the problem, then rule out its fault. Check the fuel pipe and fuel tank when you can first gasoline pump into the fuel pipe LR057813 connector with a wrench to dismantle the thing, and then use the method of sucking to determine whether the fuel pipe is blocked (but must pay attention to not sucking gasoline into the mouth), if there is an oil sucked out of the car shows that the problem is not in the car fuel pipe or tank, and perhaps the gasoline pump; but if there is no gasoline sucked out of the car can not be ignited problem! It is very likely that the fuel tank and automobile fuel pipe problems, with this earth method on the further view of the automobile fuel pipe leakage has a certain role in learning.
Automotive power steering hose LR060993 for macro-analysis, and then cut samples with wire cutting machine near the fracture. With X2650 type scanning electron microscope and EDAX29100 type X-ray energy dispersive spectrometer investigation analysis of brake fluid pipe fracture on the corrosion products, with Jiajia brand detergent and ultrasonic washing to remove the fracture of the oil with acetone and ultrasonic cleaning of the fracture, and then X2650 type scanning electron microscope investigation analysis of the clean fracture. Automobile brake fluid pipe assembly is composed of a brake fluid pipe and two hollow fixed nut. Brake fluid pipe is steel, steel outside the copper-plated layer. The flare portion of the brake fluid tube is of excellent quality and no defects are found. No cracks were found in the flare portion. The cracked position of the brake pipe is below the nut, about 15mm from the flare, and the copper plating layer is partially detached from the outer wall of the cracked brake pipe. In 5 times the magnification of the investigation, can see the shell-shaped trick, but also can see the fracture on the many brightly polished small sections, by the fracture of the macroanalysis can be initially speculated that the cracking of the brake fluid pipe for fatigue cracking.
