Recently, among the hot topics on the entire network, the issue of "high temperature of excavator water tanks" in the field of construction machinery has triggered widespread discussion. As the summer high temperature continues, many excavator truck owners and operators report that the equipment frequently has high temperature alarms for water tanks, which seriously affects the construction progress. This article will provide detailed interpretations of this hot issue from cause analysis, solutions to preventive measures, and provide structured data for readers' reference.
1. Analysis of the main reasons for high temperature of excavator water tank
| Ranking | Cause classification | Specific performance | Percentage |
|---|---|---|---|
| 1 | Cooling system issues | Insufficient coolant/deterioration, pump failure, thermostat failure | 42% |
| 2 | The heat dissipation system is blocked | Clogging of the outside of the water tank (dust, catkins), internal scale deposits | 28% |
| 3 | Improper operation | Long-term overload operation, excessive ambient temperature | 15% |
| 4 | Other mechanical failures | Fan belt slack, sensor failure, hydraulic system overheating | 15% |
2. Practical methods to solve the high temperature of excavator water tank
In response to the above issues, professional maintenance personnel recommend the following hierarchical solutions:
| Emergency | Handling measures | Key points of operation |
|---|---|---|
| Handle it now | Shut down and cool down | The high temperature alarm is found to stop immediately, and the fire will be turned off after idling for 5 minutes. |
| Short-term solution | Check coolant | Replenish the same type of coolant to check for leaks |
| Interim maintenance | Clean the heat dissipation system | Use special cleaning agent to remove blockages inside and outside the water tank |
| Long-term prevention | Regular maintenance | Change the coolant every 500 hours, check the water pump and thermostat |
3. Daily maintenance suggestions for preventing high temperature of excavator water tank
According to the latest maintenance guidelines released by the Engineering Machinery Association, special attention should be paid to the following matters in summer maintenance:
1.Cooling system inspection: Check the coolant level weekly to ensure it is between the MIN and MAX scales; use a coolant detector to test the anti-freeze and boiling properties every quarter.
2.Radiator cleaning: It is recommended to install a dustproof net. After the construction is completed every day, use compressed air to clean the heat sink from the inside to the outside; use a special cleaning agent every 200 hours to thoroughly clean it.
3.Operation specifications: Avoid continuous operation during high temperatures at noon, set a mandatory rest for 15 minutes every 2 hours; pay attention to observing the dashboard temperature indicator, and take measures immediately after exceeding 95℃.
4.Accessories replacement cycle:
| Accessories name | Replacement cycle is recommended | Brand recommendation |
|---|---|---|
| Coolant | 500 hours or 6 months | Shell, Mobil |
| Thermostat | 2000 hours | Tianbo, Male |
| Water pump | 4000 hours | Gates, Bosch |
| Fan belt | 1000 hours | Handong, Samsung |
4. Special reminders from industry experts
The recently issued summer warning by the China Construction Machinery Maintenance Association specifically pointed out:
1. Statistics of excavator failures in the past three years show that the high temperature problem of water tanks from July to August accounted for 63% of similar failures throughout the year, and it should be taken seriously.
2. The corrosion problem caused by using inferior coolant is more serious than expected, and the maintenance cost is often 5-8 times that of high-quality coolant.
3. The installation of intelligent monitoring equipment can be used for early warning. The new OBD diagnosis system can predict high temperature risks 30 minutes in advance. It is recommended to upgrade and renovate old equipment.
4. Operator training is crucial, and the survey shows that 75% of operators do not know the correct emergency treatment process, resulting in secondary damage.
5. Answers to the 10 questions that users care about the most
| question | Professional answers |
|---|---|
| Can I add cold water directly when the temperature is high? | Absolutely prohibited! Must wait until the temperature drops below 50°C, and add slowly |
| What happens if coolants are mixed? | Different formulas will produce sediment and block the pipeline, which must be completely drained before replacement. |
| What is the normal water temperature? | 80-95℃ is the normal operating temperature. If it exceeds 105℃, the machine must be shut down immediately. |
| How to judge thermostat failure? | There is a large temperature difference between the upper and lower water pipes after a cold car is started, or the water tank is not hot when the temperature is high. |
| How often should I clean my water tank? | Once every 200 hours in normal environment, once every 100 hours in dusty environment |
It can be seen from the above system analysis that the problem of high temperature in the excavator water tank requires the establishment of a complete response system from prevention, monitoring to emergency treatment. It is recommended that users establish standardized maintenance files, conduct regular professional inspections, and strengthen operator training. Only by taking comprehensive measures can equipment damage and shutdown losses caused by high temperatures be effectively avoided.
