What causes the insufficient air pressure in the mixer system? How should we check and repair? The following is a detailed answer for you.
If the hydraulic pump of the fully automatic concrete mixer truck outputs oil, we can check whether it works normally in time.
If it is abnormal, it may be that one of the equipment accessories in the pressure oil circuit is stuck in the oil return position for other reasons, resulting in short circuit of the pressure oil circuit and overflow circuit, or it may be that the pipe joint is loose, when some of our equipment in the oil circuit leaks oil, or the hydraulic cylinder and hydraulic motor seals are damaged.
The elimination method is to directly remove the relevant equipment for cleaning to see if there is any damage to the corresponding equipment, and then replace it when necessary. It is time to check.
Check whether the hydraulic pump of the automatic mixer can output hydraulic oil. If the new hydraulic pump is said to have no hydraulic oil, it may be that the pump body is defective and the oil suction chamber is connected with the oil pressure chamber. If the oil pressure capacity is lost, it should be replaced in time.
If there is no new hydraulic pump and no hydraulic oil output, it is possible that the steering is improper and the components are seriously worn or damaged. Replace them in time.
The hydraulic system of the fully automatic concrete mixer can be set to normal pressure. Some pipes or hydraulic cylinders have no pressure in the middle, which may be due to blockage of pipes, orifices or throttle valves, reversing valves and other parts. Therefore, it is necessary to carefully check whether there is oil passing through the pressure to find out the cause, but it was ruled out later.
This is the reason why the air pressure of the mixer system is insufficient. More relevant information can be found on our website http://www.0315ms.com Consult!
