Xiamen loader training school is located at Torch North Road 15, Huli District, Xiamen. The training cost of loader is 5600 yuan, and the training time is about one month. The simulated test questions are provided completely free of charge and updated in real time. Loaders mainly involve practical operation.
Mechanical introduction:
Loading diesel engine is composed of various mechanisms and components. As a complex machine for energy conversion, although its specific structure is different, its main structure is similar, mainly composed of the following parts:
1, crank-connecting rod mechanism. It mainly consists of a machine body group, a piston connecting rod group and a crankshaft flywheel group. The diesel engine converts the reciprocating linear motion of the piston into the rotary motion of the crankshaft through the crank-connecting rod mechanism to complete the working cycle of the diesel engine.
2. Valve mechanism. It is mainly composed of valve group and transmission mechanism, and its main function is to complete the opening and closing of intake and exhaust valves in a certain order, so as to ensure that the diesel engine can suck in fresh air and discharge the exhaust gas after combustion in time.
3. Fuel supply system. It mainly includes fuel injection pump, fuel injector, fuel transfer pump, governor and fuel filter. Its function is to inject human diesel into the combustion chamber regularly, quantitatively and at constant pressure to ensure the timely, rapid and complete combustion of fuel.
4. Lubrication system. It is mainly composed of oil pan, oil pump, oil filter, lubricating oil pipe and various valve parts. Its main function is to transport lubricating oil to various friction surfaces, so as to reduce the wear and tear of diesel engine parts, reduce the friction resistance between parts, and also play a role in cooling, cleaning and sealing.
5. Cooling system. It is mainly composed of radiator, fan, water pump, cooling water jacket, cylinder body and thermostat in cylinder head. Its function is to transfer the heat absorbed by the parts in time to ensure the normal working temperature of the diesel engine.
