Excavator concrete crusher usage tips and maintenance methods

[BONOVO]

With the acceleration of urbanization, demolition projects and foundation construction are frequent, and more and more construction units have begun to pay attention to the application of "excavator concrete crusher". Reasonable use and scientific maintenance can not only improve work efficiency, but also significantly extend the service life of the equipment. This article will introduce you in detail the "excavator concrete crusher usage skills" and "excavator concrete crusher daily maintenance methods" to help you with ease in construction.

Basic working principle of excavator concrete crusher

"Excavator concrete crusher working principle" is based on hydraulic system drive, and the concrete structure is broken into pieces through high frequency and high impact. The crusher is generally installed at the front end of the excavator, relying on the high-pressure oil provided by the host as the power source, and shows extremely high adaptability in different construction environments, such as bridge demolition, foundation crushing, old building renovation and other scenes.

Understanding the working principle is the prerequisite for mastering correct operation. Familiarity with the hydraulic system response speed, crushing force adjustment range and return oil setting is crucial to improving overall work efficiency.

Excavator concrete crusher usage skills

Correctly mastering the "excavator concrete crusher efficient operation skills" can not only improve crushing efficiency, but also reduce equipment loss. The following aspects are particularly important:

1. Correctly select the crushing angle

During operation, the breaker should be kept in vertical contact with the concrete surface. The wrong angle not only affects the crushing effect, but also easily causes "excavator concrete crusher hydraulic system failure", which may even cause the equipment to be scrapped prematurely in the long run.

2. Avoid empty hits

The so-called empty hits refer to the breaker hitting the air or soft objects without load for a long time. This situation can easily lead to increased wear of internal parts such as piston rods and sealing rings. Therefore, in actual operation, it is necessary to ensure that the hammer head hits the target accurately to avoid ineffective operations.

3. Control the frequency and intensity of the strikes
Different concrete strengths require different strike modes. By reasonably adjusting the strike frequency, energy consumption and crusher wear can be greatly reduced. Mastering the "excavator concrete crusher strike intensity adjustment skills" can enable the equipment to adapt to various complex construction environments.

4. Avoid continuous high-temperature operations

Long-term high-intensity operations will cause the hydraulic oil temperature to be too high, affecting the performance of the crusher and even damaging the hydraulic system. It is recommended to take a 10-15 minute break every 2 hours of operation, or use equipment with an oil temperature monitoring system to grasp temperature changes in real time.

5. Pay attention to the surrounding environment
When working in a small space, special attention should be paid to the swing range of the machine to prevent the crusher from accidentally colliding with obstacles such as walls and steel bars during the striking process, so as to avoid "damage to the excavator concrete crusher body".

Daily maintenance methods for excavator concrete crushers
Scientific maintenance is the key to ensuring the long-term stable operation of the equipment. Here are some practical "excavator concrete crusher maintenance tips":

1. Check the hydraulic oil regularly

The quality of hydraulic oil is directly related to the performance of the crusher. It is necessary to regularly check whether the oil quantity and oil quality are qualified, and replace the aging or seriously contaminated hydraulic oil in time to avoid the "excavator concrete crusher hydraulic oil pollution problem".

It is generally recommended to replace the hydraulic oil every 500 hours of operation or half a year, and replace the oil filter at the same time to keep the system clean.

2. Check the tightening of the bolts

The crusher is subjected to great impact during operation, and long-term use can easily cause the bolts to loosen. You should develop the habit of checking the tightness of the bolts at the connection parts before daily operation, especially the key positions such as the mounting flange and connecting arm.

3. Replace wearing parts in time

Drill rods, sealing rings, accumulators, etc. are high-frequency wearing parts. Wear not only affects the crushing effect, but may also cause more serious internal damage. Mastering the "excavator concrete crusher wearing parts replacement cycle" and doing regular preventive maintenance is much more cost-effective than overhauling afterwards.

4. Pay attention to the lubrication of the impact head

Regularly filling the impact head with special grease can help reduce friction and reduce wear of internal parts. It is generally recommended to add it once a day, and the number can be appropriately increased during high-intensity operations.

5. Check the accumulator air pressure

Some crushers are equipped with an accumulator system to buffer the pressure fluctuations caused by the impact. Regularly checking whether the accumulator nitrogen pressure is normal can effectively avoid the problem of weak impact due to insufficient air pressure.

Common faults and countermeasures

In actual use, the "common fault repair methods for excavator concrete crushers" are also very important. The following are some common faults and solutions:

Breaker powerlessness: Check whether the hydraulic oil pressure meets the standard and whether the nitrogen pressure is sufficient.

Abnormal noise during operation: It may be that the impact head is loose or the internal parts are worn. It is necessary to stop the machine for inspection and replace the damaged parts.

Hydraulic oil leakage: Check whether the sealing ring and joints are damaged, and replace or tighten the relevant parts.
