The small mixer truck has simple structure and convenient operation, but there are also many small problems in the operation, such as not unloading. Although it is a small problem, we also need to find the reason and solve it.
Under normal circumstances, the mixer will unload automatically when the mixing time reaches zero, but when the mixing time comes, the mixer does not unload when the pause button on the console is pressed during the production process. At this time, first check the solenoid valve on the discharge door of the mixer to see whether the solenoid valve is damaged. If the solenoid valve is damaged, the discharge door will not open, and the mixer will not discharge naturally, so the solenoid valve needs to be repaired.
If it is not the fault of the solenoid valve, it is necessary to check whether the pause button on the console is pressed. If not, press it. If there is no problem with the buttons on the console, it is necessary to check the monitoring interface of the computer to see whether the discharge prohibition control on the monitoring interface is activated. If it is activated, it will be cancelled immediately. If there are no problems above, the mixer truck is broken, so you need to check the mixer.
The discharge door of the main machine of the small mixer truck is automatically controlled. If the discharge door of the mixer truck cannot be opened normally, the operation of the whole equipment will be seriously affected. The common reason why the discharge door cannot be opened may be that there is foreign matter or material accumulation between the discharge door and the sealing plate.
The pressure of the air circuit system is insufficient, the cylinder leaks or the oil mist is damaged; The wiring between the solenoid valve and the relay falls off, is falsely connected, or the relay is damaged; The solenoid valve coil is burnt or the valve element is stuck; The time relay is damaged, etc.
The countermeasures we take are also mainly the following. If there is foreign matter or accumulated material between the discharge door and the sealing plate, clean the foreign matter and accumulated material and flush the discharge door; If the air system pressure is insufficient, the cylinder leaks or the oil mist is damaged, check whether the oil mist, connector, cylinder and other parts are damaged; If the wiring between the solenoid valve and the relay falls off, is falsely connected, or the relay is damaged, check the relay contact output and wiring, and replace it if necessary; If the solenoid valve coil is burned or the valve core is stuck, replace the solenoid valve; If the time relay is damaged, it should be replaced.
The above is the routine inspection method when the mixer is not unloaded. For more information, please click our website http://www.zkzsljbc.com Consult customer service for more information.
