What Should I Do If The Oil Temperature Of The Concrete Pump Rises Too Fast?

Concrete pumps are crucial equipment utilized in engineering construction. They have the ability to boost the efficiency of concrete construction greatly. However, the longer they are used, the more likely it is for their oil temperature to rise too quickly. So, how can we deal with this situation?

The rise in oil temperature of a concrete pump can easily lead to equipment malfunction, which compromises the construction's safety and success. Fortunately, there are a few effective ways to handle this problem. Regular maintenance is key to prevent the temperature from rising too quickly. Maintenance can include cleaning the pump's filters, checking the oil level regularly, and topping up the oil when necessary. Additionally, it's advisable to inspect the heat exchanger and clean it accordingly.

Another excellent solution is to install an oil cooler to counteract the rise in temperature. The oil cooler helps to maintain the oil temperature at a suitable range, ultimately preventing equipment malfunction.

In conclusion, we must take the rising oil temperature in concrete pumps seriously. However, we now have simple and effective solutions to tackle this issue- periodic maintenance and oil coolers. These solutions can guarantee successful concrete construction operations.

If you notice a sudden increase in oil temperature and weak direction during the operation of your concrete pump, this could indicate a possible hydraulic system leakage. In such cases, it is recommended to start by checking the pressure at the oil outlet of the hydraulic pump. If the pressure is normal, it indicates the pump is working as intended. You can then proceed to measure the pressure at the inlet of the accumulator. A significantly low pressure reading would imply that the airbag of the accumulator is most likely damaged and needs to be replaced. Remember to conduct a thorough test of the machine afterward to ensure everything is functioning optimally.

If the issue persists, it is possible that the weak reversing and increased oil temperature are caused by a leakage in the one-way valve between the pump and the accumulator. Typically, after a recent shutdown, you may hear a hissing sound indicating the unloading of pressure oil. In such cases, it is recommended to disassemble the one-way valve for inspection. If the sealing surface of the valve is significantly worn and the hydraulic oil appears cloudy with slight emulsification, it is advisable to replace the one-way valve as well as the hydraulic oil. After conducting these steps and testing the machine, you will observe that the pump's performance returns to normal.
