How to Solve the Problem that the Excavator Stalls and Slows Down?

As an Excavator Spare Parts Manufacturer, share with you.

1. Exhaust pipe

Under normal circumstances, exhaust clogging is one of the main reasons for reducing fuel consumption. When the exhaust pipe is blocked, the exhaust power is directly reduced. Therefore, it is necessary to check the carbon deposits in the exhaust pipe regularly in daily work. If the back pressure exceeds 3.3Kpa, it must be cleaned.

2. Air filter

If the air filter is dusty or dirty, the efficiency of the filter will decrease linearly, blocking air circulation and affecting the engine output. Therefore, the alias must be timely. The air filter, air filter or clean filter paper, if it is serious, you can directly replace the new filter.

3. Piston and cylinder liner

With the increase of mechanical use time, the strain loss between the piston and the bushing gradually increases. Excessive piston ring wear can have serious adverse effects on the engine and may cause adverse reactions, such as difficulty in ignition and incomplete combustion. Therefore, please check the cylinder liner and piston ring regularly.

4. Fuel filter

When the air enters the fuel filter, the pipeline is directly blocked, and the oil passage smoothly reaches the position. This directly leads to power shortage. In severe cases, it may affect the fire. Therefore, the fuel system must be filtered in time. Check the air in the air patrol. If necessary, you can choose to replace the new diesel filter (filter material: glass fiber filter paper, chemical fiber filter paper, etc.).

5. Cooling and lubrication system

The main cause of oil overheating is the failure of the mechanical cooling system or lubrication system (circulating lubrication system, centralized lubrication system, etc.). Therefore, when the exhaust temperature of the diesel engine increases, the cooler and radiator can be checked. Our company also has Hitachi Bucket Adapters for sale.

Why does the excavator cause slow motion?

Common causes:

1. The oil cooler is clogged.

2. The speed of the oil cooling fan does not match.

3. The set pressure of the main release valve and the door release valve, and the pressure of the operation release valve is lower than the standard value.

4. The pressure of the main relief valve is too high.

5. The hydraulic oil level is incorrect.

The minimum maintenance procedures of the excavator:

1. First, is the hydraulic oil level correct? correct.

2. Is the oil cooler blocked and the air circulation blocked? normal

3. Does the speed of the oil cooling fan reach the specified value? normal

4. Are the set pressures of the main release valve, door release valve and operating release valve lower than the standard value? The standard value is normal.

5. Is the pressure of the main relief valve too high? too much stress.
