How should the concrete trailer pump be checked?-truemax
After the installation of the tow pump is completed, be sure to check the overall structure and maintenance device of the tow pump.
1. The contents that need to be checked usually include: whether the liquid level in the filling is within the specified range, whether the hydraulic hose joints and the joints of the clamping base are loose, whether there is oil leakage, whether the electrical elements are broken, whether the contacting screws are loose, Is there any debris in the pre-neodymium ignition funnel, mass, etc. These are the inspection scopes for concrete drag pumps.
2. Electrical inspection of concrete traction pump. The electrical inspection is whether the excitation voltage is (38 010%) V. Usually, the concrete traction pump should be equipped with a special control switch. The cable used should be of the same size as the main cable on the concrete traction pump. At the same time, it should be properly wired as required, and the following checks should be carried out.
At the same time, it should be properly wired as required, and the following checks should be made:
a. Turn off the control circuit switch, the power indicator light is on, and the programmable logic controller (PLC) module obtains power. At this point, the LEDs on the observation module come on (start, run, and fault, respectively). If the start and running lights are on and the fault light is off, it means that it can operate normally, otherwise it is abnormal and the concrete drag pump cannot run.
b. Press the motor start button to check whether the motor AC contactor works according to the program, and whether the motor indicator light is on.
c. Press the buttons of concrete traction pump, reverse pump, pressure test, and stirring to check whether the programmable controller has input and output signals.
