Mixer truck is a common means of transportation for concrete and clay. It should be ensured that there is no error during transportation. During the whole process, concrete and soil will be mixed, so that the quality of concrete and clay can be maintained well until the destination is reached. The application requirements of the hydraulic rotation system are as follows:
1. Before using a new car, first check and remove the dust and sundries in the hydraulic system, and check whether the connections are correct and whether there are other problems.
2. The oil tank is filled with hydraulic oil above the oil mark, and the pump housing and motor housing are also filled with oil.
3. Start the engine, operate the servo handle to make the mixing drum of the small mixer rotate forward at low speed, and observe whether the hydraulic system works normally.
4. The oil temperature shall not exceed 60 ℃, and the pump casing pressure shall be less than 0.25MPa.
5. Note that the fan on the radiator should be running in the range of 50 ℃ - 70 ℃. When the fan fails to work, it should be repaired in time.
6. The pressure of the relief valve, low pressure relief valve and high pressure relief valve of the make-up pump has been set before leaving the factory and shall not be changed at will.
7. The components and pipelines in the oil circuit of the small mixer shall not have oil leakage. In case of leakage, they shall be repaired in time.
8. It is not allowed to repair and adjust at will when working.
9. If the hydraulic oil pump and Mada break down, they should be replaced in time and sent to the professional designated maintenance department for repair.
We should do a good job in all aspects of the inspection when driving a small mixer. The hydraulic rotation system is a key part of the whole mixer. Only when the hydraulic rotation system meets the use requirements can we use the mixer efficiently.
