Wholesale doosan excavator parts manufacturer and supplier in Guangzhou

By sea, air or by express ( DHL, Fedex, TNT, UPS, EMS)

Regularly lubricate the swing bearing, check if the grease is sufficient, inspect the bearing for wear or looseness, and adjust or replace it if necessary.

1.There is no oil in the fuel tank.

2.The fuel filter and oil-water separator are blocked.

3.The low-pressure oil circuit does not supply oil.

4.The injection pump does not pump oil.

5.There is air in the oil circuit.

6.The valve timing is misaligned. The opening time of the valve is not coordinated with the stroke of the piston in the cylinder. For example, when the piston makes a compression stroke in the cylinder, the intake and exhaust valves are open, and fresh air is driven out of the cylinder, so that there is no combustion gas in the cylinder and it cannot start.

7.The solenoid valve of the injection pump is broken and is in a closed state, and the diesel cannot enter the high-pressure chamber.

1.The climate is cold in winter, the ambient temperature is low, the viscosity of the engine oil increases, and the friction resistance of each moving part increases, which reduces the starting speed and makes it difficult to start.

2.The battery capacity decreases as the temperature drops, which further reduces the starting speed.

3.Due to the reduction in starting speed, the leakage of compressed air increases, and the heat dissipation of the cylinder wall increases, which greatly reduces the temperature and pressure of the air at the end of compression, and increases the delay period of diesel ignition. In severe cases, it may even fail to burn.

4.The viscosity of diesel at low temperatures increases, which reduces the injection speed. In addition, the swirl speed, temperature and pressure of the air at the end of compression are relatively low, which makes the atomization quality of the diesel injected into the cylinder poor, making it difficult to quickly form a good combustible gas with the air and ignite and burn in time, or even fail to ignite, resulting in difficulty in starting.
