Tips for autumn excavator maintenance

1、 Engine compartment inspection
It is important to promptly clear away any leaves and debris that may have fallen into the engine, exhaust manifold, muffler, and engine compartment. You can make use of compressed air to effectively blow away dust and debris that have settled on the radiator's surface. Alternatively, when the engine is cool, you can use a gentle stream of water to flush out any impurities from the inside out. However, be cautious about controlling the water pressure and the angle at which you flush, as well as avoiding excessive water contact with electrical connectors.

 

It is important to ensure that the engine oil and antifreeze are of good quality. It is crucial to check them regularly to make sure that they are up to the mark. A good quality engine oil and antifreeze can help your engine run smoothly, prevent it from overheating and protect against damage. Therefore, it is crucial to make sure that the engine oil and antifreeze are in optimal condition at all times.

 

2、 Battery maintenance
To begin, it is important to connect the positive terminal of the battery to the positive terminal of the power supply, and likewise, connect the negative terminal of the battery to the negative terminal of the power supply. It is crucial to take note of the polarity and avoid any reversal of the connections when engaging in the charging process.

 

The charging process for a new battery typically involves two stages. At first, an initial charging current is utilized to charge the electrolyte until bubbles emerge and the single cell voltage increases to between 2.3-2.4V. After that, the current is reduced to half of the initial charging current and the charging process is continued until the electrolyte releases aggressive bubbles and the voltage stabilizes for three consecutive hours. This final stage typically lasts for approximately 45-65 hours. It is important to follow these charging procedures for optimal battery performance and longevity.

 

While charging batteries, it is essential to monitor the temperature of the electrolyte regularly. This can be achieved by reducing the current, stopping the charging process or even cooling the electrolyte to keep the temperature at an optimum range of 35-40 ℃. In cases where the initial specific gravity of the electrolyte is not in line with the set standards, it is advisable to use either distilled water or electrolyte with a specific gravity of 1.4 as an adjustment solution. After adjusting the electrolyte, it is recommended to charge the battery for an additional two hours until the specific gravity meets the set requirements.

 

Another issue that could arise during the winter season is with the battery's electrode connection. The poles of the battery are prone to oxidation and corrosion, which can lead to faulty connections and prevent the equipment from working as intended. It's crucial to stay on top of maintenance and address any problems as soon as they arise.

 

3、 Connector detection
During the rainy summer months, it is crucial to conduct a thorough examination of the plug to ensure its stability. Careful inspection should be carried out to detect any signs of connector looseness or pin corrosion. If any abnormalities are detected, it is advised to utilize specialized cleaning agents for effective treatment. Furthermore, regular circuit inspections are essential to identify signs of aging or damage. In such cases, immediate measures must be taken to protect or replace the affected components to prevent potential short circuits, which can lead to hazardous electrical fires.

 

It's crucial to maintain heating pipelines and air conditioning to keep them in good condition. Proper maintenance ensures that these systems function efficiently and are less likely to break down.

 

Heating pipelines need to be checked regularly for leaks and cracks. Damaged pipelines can cause heat loss, increase energy consumption, and compromise indoor air quality. Additionally, air conditioning systems need to be serviced regularly to maintain their efficiency. Clogged filters not only reduce cooling capacity; they also increase electricity bills.

 

In summary, routine maintenance of heating pipelines and air conditioning is essential to ensure optimal performance, prevent breakdowns, and save energy. It's worth investing in a professional inspection and cleaning service to keep your systems in top condition.

 

As the temperature steadily drops, it is important to keep an eye out for the formation of white frost, which can occur when the weather gets extremely cold. To ensure a safe working environment in warm conditions, it is crucial to promptly inspect the heating pipes and associated valve switches (small excavations), as well as examine the relevant air ducts and vents for any potential issues.

 

5、 Rotary oil pool lubricating grease inspection
Check the rotary oil pool's lubricating grease for any presence of an anhydrous oil blend. It is important to ensure that the lubricating grease is thoroughly inspected to maintain the quality and effectiveness of the oil pool.

 

6、 Equipment paint maintenance
Paint serves a dual purpose of both enhancing the appearance of equipment and providing anti-rust protection. During the rainy season, the strong sunlight and acidic compounds in the rainwater can cause oxidation and corrosion of the paint surface. Furthermore, the harsh conditions of construction projects can also lead to damage to the paint surface. Therefore, in order to maintain the equipment's condition, it is advisable to perform selective and timely paint touch-ups based on the individual needs of the equipment.
