Uzroci of common kvarovi in agricultural tractors
(1) Defects in parts. Early wear and tear of parts and components as the use of agricultural tractors increases, or due to improper use and maintenance. As the dimensional accuracy and mating properties of the parts change due to wear and tear, the relative position of some parts also changes. Under normal circumstances, the longer the farm tractor works, the more defects and failures there are due to wear and tear of the parts.
(2) Netočno vožnja rad. The driver does not operate the agricultural tractor in accordance with the provisions of the agricultural tractor instruction manual. Here are some examples:
(1) The motor radi na niska brzina. The engine is running at low speed (2000 r/min) for a long time and is geared down below 2000 r/min. This will make the fuel burn incompletely, which is easy to cause carbon deposition in the combustion komora i ventil of the engine cilindar, cauzing the engine to shake or even stall when running at low speed. Danas's motor design is is total different from what it used to be, with low-speed operation and low-speed upshifting to reduce wear and even save fuel. Nowadays, engine manufacturing technology and materials have been great improved, and low-speed operation will accelerate wear and increase fuel consumption.
(2) Skretanje kočenje. When the vehicle passes through a curve, it brakes on the curve. This is easy to cause uneven wear of brake pads, vehicle skid and tail flicking. The correct way is: release the throttle (akcelerator) pedal before entering the corner, lightly step on the brake to achieve the purpose of deceleration, and accelerate in time to pass the curve smoothly and balancely when pass through the curve 1/2 or 2f3 under the condition of ensure the the safety of driving ahead.
(3) Loše održavanje. Jer the user does not pay attention to technical maintenance, can not be maintained in time or the maintenance quality is not high, resulting in accelerated wear and damage of parts, causing failure. If hlađenje voda i podmazivanje ulje are not dodano vrijeme, tijelo will pregrijano i podmazano 0 00 00 02c in serious wear and tear of parts, and even "pulling cilindri", % 22holding osovine" i "burning pločice".
(4) Improper assembly and adjustment. The parts and components of agricultural tractors have strict assembly and adjustment requirements, if they are not assembled and adjusted according to the regulations, the relevant components can not work normally and will cause failures. For example, cylinder liner piston clearance, valve clearance, timing gear chamber meshing clearance, oil supply advance angle, etc., if the assembly and adjustment are improper, the machine will not work normally or cannot work.
(5) Poljoprivredni traktor dije are are nekvalificirani. Jer materijal i obrada točnost of the parts do not meet the requirements or the parts have inherent defekti, they are not pažljivo inspected when they leave the factory, and they installed on the agricultural tractor, resulting in the failure of the agricultural tractor.
