The mixing drum of automatic mixing machine is an important part of it. So what is the reason for the failure? How can I solve it? Next, let's talk.
Generally, the mixing drum of the mixer truck does not rotate for two reasons: (1) hydraulic system or engine failure, and (2) motor failure. The treatment method is as follows.
1. Troubleshooting of hydraulic system or engine:
(1) Open the inspection hole cover of the mixing drum of the mixer used to transport concrete, loosen the pipe joint of the high-pressure hose of the motor, rotate the mixing drum, rotate the inspection hole of the mixing drum obliquely downward, and then check the concrete mixing drum. Drain from the hole.
(2) Remove the high-pressure hose of the failed vehicle from the motor, connect the high-pressure hose for emergency use, connect the other end to the oil pump of the ambulance, and connect one end of the emergency oil return pipe to the motor drain of the failed vehicle. Do it. The other end of the oil return pipe is connected to the oil pump return port of the ambulance, and the ambulance controls the rotation of the mixing drum of the failed vehicle to discharge the concrete.
Field tests show that after all the tools in the manufacturing plant are completed, it takes about an hour to adopt the two methods, which may be time-consuming at the construction site, so one method is to discharge the concrete. Recommended.
2. Motor fault: easy to handle. Unload the motor of the rescue vehicle, connect it to the failed vehicle, connect each oil pipe, start the rescue vehicle and drain the concrete in the mixing drum.
In other words, when a failure occurs in the mixer truck transporting concrete, the cause must be found early and measures such as pouring concrete into the mixing drum must be taken to eliminate the failure.
