Causes of strong heat failure of small agricultural excavators

1. Under normal circumstances, the low-speed operation of the small excavator may be a problem with the hydraulic oil circuit of the agricultural small excavator. Oil leakage in the hydraulic oil circuit will cause the hydraulic oil and hydraulic pressure of the small agricultural excavator to not rise. This leads to a decrease in the strength of small agricultural excavators. Therefore, when this phenomenon occurs between the cold car and the hot car of the small agricultural excavator, it is necessary to check the oil circuit of the small agricultural excavator and check whether there is oil leakage at the connection of each pipeline. oil phenomenon.

2. If the hot car does not work, the manufacturer of the small agricultural excavator may be due to the failure of the oil circuit of the small agricultural excavator and the engine power is not enough.

3. The small agricultural excavator has been used for too long, the main pump is worn, or the pressure value of the main pump is inconsistent with the factory pressure and flow value of the small agricultural excavator, resulting in low power of the excavator.

4. The relief valve has been worn out.

5. If you check the oil circuit, engine, main pump and safety valve, it still cannot be ruled out that the cold power hot car of the agricultural mini-excavator is not powered off, it may be the PLS pressure leak, and the main valve must be removed.
