Five systems Five systems include Lubrication, Cooling, Fuel supply, Starting, and Ignition. The difference between the gasoline engine and diesel engine is slightly different, the difference lies in the ignition system, you know that the gasoline engine is spark plug ignition, and the diesel engine is using the mode of combustion, so there will be […]
Two institutions Generally speaking, the engine can be divided into two major mechanisms and five systems in the mechanical structure. Gas distribution mechanism Composition Most gas distribution mechanism adopts the top valve type gas distribution mechanism, which is generally composed of a valve group, valve transmission group, and valve drive group. The distribution mechanism mainly […]
Inspection and maintenance of hydraulic steering tank The oil tank is set on the right side of the body under the cover of the machine cover, and if there is no oil mark on the oil ruler, if there is no oil mark, it is necessary to check and find out the cause of the […]
Matters needing attention 1. The new or overhauled tractor must be used normally after run-in. Each part of the tractor should be strictly used in accordance with the oil products and solutions recommended by the manufacturer. 2. Do not increase the engine speed only by controlling the throttle. Check the bolts, nuts, and other loose […]
The crankshaft repair Repair of crankshaft wear Generally speaking, the diameter of the journal is below 80mm, and the error of roundness and cylinder is more than 0.025mm; Or the journal diameter is more than 80mm. Crankshaft with roundness and cylinder error of more than 0.0400 shall be repaired according to the specified size, or […]
Crankshaft machining Blank (small crankshaft for forging, large crankshaft for nodular cast iron), forging is to burn the barred through the multi-channel forging die, forging into a multi-turn plane, in the red and hot state of the last process to turn each nut to the corresponding Angle. 1) car positioning, find the center of the […]
The function of the cooling system is to keep the engine within the appropriate temperature range under all working conditions. The cooling system should prevent both engine overheating and winter engine overcooling. After the engine starts cold, the cooling system also ensures that the engine heats up quickly and reaches the normal working temperature as […]
Principle of lubrication system action The lubrication system of the diesel engine of the diesel generator set is the main part of the diesel engine depends on the pressure oil supplied by the oil pump to lubricate, its oil circuit forms a circulation system, and other parts are lubricated by splash oil. The oil of […]
The fuel supply system of the diesel generator set is generally composed of the fuel storage system, fuel transport system, and fuel filtration system. Let me introduce you to the fuel system of the diesel generator set. Fuel Storage Box The main tank is a large oil tank that stores fuel, and the general fuel […]
1. Use high-quality diesel Diesel is a complex mixture of hydrocarbons, so it is difficult to ignite. The quality of diesel is the guarantee of “healthy” operation of diesel engines, and the inferior diesel containing water or impurities will cause serious damage to the high pressure distribution pump. So for users, the best way is […]
