FAQ
As a high-end construction machinery brand, Liebherr excavators have excellent performance and quality, but they may still encounter some common problems in long-term use.
Hydraulic system abnormal noise problem?
Hydraulic system abnormal noise problem Fault phenomenon:
After starting, the hydraulic pump of the Liebherr excavator makes obvious abnormal noise, which may be manifested as high-frequency whistling or dull roaring, and may be accompanied by foaming of the hydraulic oil.
Cause analysis:
Hydraulic oil filter element blockage will cause the oil circuit to be blocked and form a partial vacuum
Hydraulic system intake, air mixed into the oil to form cavitation
Long-term non-replacement of hydraulic oil leads to oil quality deterioration and viscosity change
Wear of internal components of the hydraulic pump, such as damage to the distribution plate or plunger
Oil tank breather blockage, resulting in negative pressure state
Solution:
Replace hydraulic oil and filter element:
Use the original factory specified model hydraulic oil (such as HV46 or similar specifications recommended by Liebherr)
Replace the main return oil filter element and high-pressure filter element
It is recommended to replace the main return oil filter element and high-pressure filter element every 2000 Working hours or replace once a year
System exhaust operation:
Start the engine at low speed
Operate each actuator to the limit position in turn
Maintain reciprocating motion of each cylinder for 10-15 times
Check the oil tank level and replenish it in time
Check the pipeline sealing:
Focus on checking the connections of the pump suction pipeline
Tighten all joints with a torque wrench
Replace O-rings and seals when necessary
Professional inspection:
Use a hydraulic tester to detect system pressure
Check the volumetric efficiency of the pump (should be no less than 85%)
Dismantle and repair or replace the hydraulic pump when necessary
What are the causes of wear on the excavator chassis?
1. Track wear
1.1 Causes of track wear
The track is a key component of the excavator chassis system. It is in direct contact with the ground, so it is prone to wear during long-term operation. The main causes of wear include:
Long-term high-intensity operation: Long-term operation on hard ground (such as rock, concrete) will aggravate track wear.
Abnormal track tension: Too loose a track will cause sliding and abnormal contact, while too tight a track will increase friction, accelerate track elongation and wear.
Environmental factors: Mud, gravel and other debris may enter the track system, causing additional friction and damage.
Improper operation: Frequent sharp turns or unnecessary high-speed driving will accelerate track wear.
1.2 Impact of track wear
Excessive track wear will cause the track to elongate and affect walking stability.
When the wear is severe, the track may fall off the sprocket or supporting wheel, causing the operation to be interrupted.
Uneven wear will cause vibration and abnormal noise, affecting the control experience.
1.3 Solutions to track wear
Check track tension regularly: ensure that the track is moderately tight to avoid extra wear caused by being too loose or too tight.
Reduce sharp turns and high-speed driving: Reasonable operation can effectively reduce track wear.
Clean tracks and track systems: After operation, the mud, sand and gravel on the tracks should be cleaned in time to prevent foreign objects from accelerating wear.
Use high-quality tracks: Selecting tracks made of wear-resistant materials can effectively extend the service life.
2. Damage to track rollers and idlers
2.1 The role of track rollers and idlers
Track rollers and idlers are important components of the track support system:
Track rollers: used to support the track and guide its normal operation, while dispersing the weight of the excavator.
Idler: used to guide the track and cooperate with the tensioning device to maintain appropriate tension.
2.2 Causes of wear of track rollers and idlers
Long-term high-load operation: High-intensity earthwork operations will accelerate the wear of track rollers and idlers.
Insufficient lubrication: Poor lubrication will increase friction and cause premature bearing damage.
Foreign matter intrusion: Mud, sand, and stones entering the inside of the track roller will cause rolling obstruction and increase the wear rate.
Component aging: After long-term use, the bearings, seals, etc. of the track rollers and idlers are prone to aging and failure.
2.3 Impact of damage to track rollers and idlers
Wear of the track rollers will cause uneven force on the track, affecting the driving stability of the excavator.
Damage to the idler will cause abnormal track tension and increase the risk of track falling off.
The efficiency of the walking system will decrease, increasing fuel consumption and operating costs.
2.4 Solution
Regularly check the lubrication: Ensure that the lubrication system of the track rollers and idlers operates normally to reduce friction loss.
Clean up debris around the wheel body: Prevent mud, sand, gravel, etc. from entering the rolling parts and aggravating wear.
Replace severely worn track rollers or idlers: If obvious grooves, cracks, or rolling abnormalities are found, new parts should be replaced in time.
3. Sprocket wear
3.1 The role of sprocket
The sprocket is the driving component of the excavator's walking system, which drives the crawler to run by transmitting power. Its wear directly affects the service life and walking stability of the crawler.
3.2 Causes of sprocket wear
Excessive or insufficient track tension: Incorrect tension will cause abnormal wear on the contact surface of the sprocket gear and the track pin.
Accumulation of mud and foreign matter: If mud and sand accumulate in the sprocket area for a long time, it will increase friction and accelerate gear wear.
Improper walking method: Frequent speed changes, sudden braking and other operations may increase the impact force between the sprocket gear and the track pin, thereby accelerating wear.
3.3 The impact of sprocket wear
Track slippage: After the sprocket tooth profile is worn, the crawler may not be able to engage effectively, affecting walking stability.
Increased walking noise: Uneven wear of the sprocket will cause abnormal noise in the walking system and even affect the normal operation of other components.
Reduced operating efficiency: Reduced walking efficiency, increased operating time and fuel consumption.
3.4 Solution
Regularly check the wear of the sprocket: If the tooth shape is irregular or severely worn, it should be replaced as soon as possible.
Properly adjust the track tension: Prevent the track from being too loose or too tight, which will cause additional burden on the sprocket.
Reduce the working time in harsh environments: After working in muddy and gravelly environments, clean the sprocket parts in time to reduce the risk of wear.
4. How to extend the life of the chassis?
In addition to the maintenance measures for each component, the following general methods can extend the overall life of the chassis system:
Develop good driving habits: Avoid unnecessary sudden braking and sharp turns to reduce unnecessary stress and wear.
Clean the chassis regularly: Clean the track, supporting wheels, sprockets and other components after the operation to prevent the accumulation of foreign matter from affecting performance.
Reasonable replacement of worn parts: Replace severely worn chassis parts in time according to the usage to avoid affecting the performance of the whole machine.
Why does the engine speed drop?
The engine speed drops when it is working and cannot reach the rated speed. This phenomenon is more common in the daily use of excavators. It not only affects the work efficiency, but also may cause problems such as engine overheating and increased fuel consumption. There are many reasons for the engine speed drop, involving the fuel system, intake system, engine mechanical parts and other aspects.
Answer:
1. Fuel system failure
The fuel system is a key part of the normal operation of the engine. Any fuel supply problem may cause the engine speed to drop.
Cause:
Fuel pump failure: The performance decline or failure of the fuel pump may cause insufficient fuel supply, making the engine unable to reach the rated speed.
Fuel filter blockage: After long-term use, the fuel filter will accumulate impurities, resulting in poor fuel flow and affecting fuel supply.
Fuel injector failure: Fuel injector blockage or uneven fuel injection will cause incomplete fuel combustion and affect the engine's power output.
Solution:
Check the fuel pump: Use a fuel pressure gauge to check the output pressure of the fuel pump. If the pressure is lower than the specified value, the fuel pump should be replaced.
Check the fuel filter: Regularly check the cleanliness of the fuel filter and replace it with a new filter if necessary to ensure smooth fuel flow.
Check the fuel injector: Use professional equipment to check the injection amount and injection atomization of the injector. If the injector is found to be blocked or the injection is uneven, it should be repaired or replaced in time.
2. Intake system blockage
The blockage of the intake system will affect the intake volume of the engine, which will lead to a decrease in engine power and the speed cannot reach the rated value.
Cause:
Air filter blockage: After long-term use, the air filter will accumulate dust and impurities, resulting in insufficient intake volume.
Intake line blockage: The intake line may be blocked by impurities such as dust and oil, affecting the intake efficiency.
Solution:
Check the air filter: Check the cleanliness of the air filter regularly and replace it with a new filter if necessary. It is recommended to shorten the inspection cycle under harsh working conditions to ensure smooth intake.
Check the intake line: Check whether the intake line is blocked or damaged, clean the impurities in the line, and ensure that the intake line is unobstructed.
3. Engine mechanical failure
Wear or failure of mechanical parts inside the engine can also cause a decrease in speed.
Cause:
Incorrect valve clearance: Too large or too small valve clearance will affect the normal opening and closing of the valve, resulting in poor intake and exhaust, and affecting engine power.
Insufficient cylinder pressure: Reduced cylinder sealing, such as piston ring wear, cylinder wall strain, etc., will lead to insufficient cylinder pressure and affect the combustion efficiency of the engine.
Wear of internal engine components: Wear of crankshaft, connecting rod, piston and other components will lead to reduced engine mechanical efficiency and affect the speed.
Solution:
Check valve clearance: Use a valve clearance gauge to check the valve clearance and adjust it to the specified range. If there is still a problem after the valve clearance is adjusted, check the wear of the valve and valve seat and replace them if necessary.
Check cylinder pressure: Use a cylinder pressure gauge to check the cylinder pressure. If the cylinder pressure is lower than the specified value, check the piston ring, cylinder wall and cylinder gasket and other components, and repair or replace the worn parts.
Check the internal engine components: Disassemble the engine for inspection, and check the wear of the crankshaft, connecting rod, piston and other components. Overhaul or replace worn parts if necessary.
4. Other possible reasons
In addition to the common reasons mentioned above, there are some other factors that may also cause the engine speed to drop:
Electronic control system failure: Electronic control unit (ECU) failure or sensor failure may cause abnormal engine speed control.
Fuel quality problem: Using low-quality fuel may cause incomplete combustion and affect engine performance.
Cooling system failure: Cooling system failure causes engine overheating, which will automatically reduce the engine speed to protect itself.
Solution:
Check the electronic control system: Use diagnostic tools to check the working status of ECU and sensors, and repair or replace faulty parts.
Check fuel quality: Make sure to use fuel that meets the standards and avoid using low-quality fuel.
Check the cooling system: Check the level and quality of the coolant, check the working status of components such as the radiator and fan, and ensure the normal operation of the cooling system.
Why does the electric control handle fail?
Fault phenomenon:
The operating handle has no response or the action is not coherent, which may be sometimes good and sometimes bad, seriously affecting the accuracy of operation.
Cause analysis:
The internal potentiometer of the handle is worn
The signal transmission line is interrupted
U47/U48 control module failure
The power supply of the handle is abnormal
Software program error
Solution:
Handle detection:
Disassemble the handle to check the wear of the potentiometer
Measure whether the resistance change of the potentiometer is linear
Check the status of the micro switch
Line inspection:
Test the continuity from the handle to the control module
Check whether the plug pins are bent or oxidized
Measure whether the power supply voltage is stable
Module diagnosis:
Use the diagnostic instrument to read the control module data
Check the module firmware version
Refresh the software when necessary
Replacement suggestion:
Give priority to replacing the original handle assembly
Pay attention to waterproofing when replacing
Calibrate and test after replacement
