China Agriculture Network released the "Fiat 90-100 tractor protection experience" on May 16. The tractor model should be 100-90 (100 hp) manufactured by Fiat Farm Machinery (now New Holland). According to the company's maintenance manual, we corrected the relevant data in the article (in the text ()) for the reference of New Holland tractor users. If you have any questions about service and spare parts, please contact Harbin New Holland Tractor Company at 86702579. Since there is no technical information at hand, we can only refer to other similar models when we maintain the Italian Fiat 90-100 tractor. We must combine our existing knowledge and some tentative explorations to determine how to carry out maintenance. The summary of some experiences accumulated in practice is summarized below. Of course, if you can find relevant information, you should still rely on the information. 1 on the valve clearance adjustment problem First of all, according to the order of the rotor-type high-pressure pump to determine the engine's working order is 1-5-3-6-2-4, and then use the "twice adjustment method" to adjust. Intake valve clearance set It is 0.40-0.45mm, and the exhaust valve clearance is set to 0.60-0.70mm (the intake valve clearance should be 0.25mm, and the exhaust valve clearance should be 0.35mm). 2 About the order of the high-pressure tubing. From the outer side of the rotor pump perpendicular to the body's outlet valve, turn the ring and connect the high-pressure tubing to the cylinders of the engine 1-5-3-6-2-4. 3 About the injection pressure The new injection pressure test result is about 20Mpa. 4 About Valve Seat and Valve Replacement When necessary, we will replace the valve seat with the valve and use manual grinding. (The engine of our 100 tractor has no valve seat, and the valve sits directly on the sink seat of the cylinder liner; Grinding the valve can be done by hand grinding and grinding with a grinder) to ensure that the valve sinking amount is 0.7-0.8mm (it should be 0.7-1.0mm, the maximum allowable sinking amount is 1.3mm).
The Fluorine-Containing Benzoic Acid series is very common form of the fluorochemical compounds, it has many product types and derivatives. Most of products are in white crystalline powder, some of products are Colorless monoclinic prismatic crystals. It was widely used as fungicide intermediates, also used in the etching process. The Fluorine-Containing Benzoic Acid series are mostly in high value-added , less polluting products. We are trying our best to make our production dock with market to give accurate and effective services for the market .
