The function of the driving device is to drive the rotation of the concrete storage tank. It consists of power take-off, cardan shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling device. For concrete mixers, the drive is still very important, so let's take a closer look.
1. The universal rotating part is the part that often breaks down. Grease shall be added in time, wear condition shall be checked frequently, and repair and replacement shall be carried out in time. The team should have a spare cardan shaft assembly to ensure that in the event of a failure, it can return to work in dozens of minutes.
2. Make sure the hydraulic oil is clean. The working environment of concrete mixer is bad, so it is necessary to prevent the dirty cement sand from entering the hydraulic system. The hydraulic oil should be changed regularly according to the manual. When it is found that the hydraulic oil is mixed with water or sand during the inspection, it is necessary to stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.
3. Ensure that the hydraulic oil cooling device is effective. It is necessary to clean the hydraulic oil radiator regularly to prevent the radiator from being blocked by cement, check whether the electric fan of the radiator operates normally, and prevent the temperature of the hydraulic oil from exceeding the standard. As long as the hydraulic oil is cleaned, there will not be many failures of hydraulic parts, but the service life of different manufacturers will be different.
Generally speaking, if the driving device stops working due to failure, the concrete tank will not rotate normally, which will also lead to the scrapping of concrete in the vehicle, and even the whole concrete tank will condense in the tank, resulting in the scrapped concrete mixer. Therefore, whether the driving device is reliable or not is a problem that must be paid attention to in use.
