    What measures should be taken when pipe blockage and tubing burst occur in small concrete pump trucks?

    When pipe blockage occurs, its main symptoms are: press the positive pump to start, can not achieve reversal. In this case, you can press F1, then press the positive pump start button to see how much the pressure gauge of the main system is. If the value displayed on the pressure gauge is 31.5 Mpa, it means that the pipe has been blocked.

    Processing method: First press the back pump start button, let the back pump unload two times, then hit the pump pipe with a hammer, listen to the sound, so as to determine the location of the pipe blockage, and then remove and clean up.

    Tube burst of small concrete pump truck: When pumping, because the pipe wall will be worn thin when conveying concrete, the pump tube can not bear the pressure of pumping concrete, so the pipe burst. When removing the burst pipe and replacing it, we should pay attention to the reverse pump several times, then remove it and replace it with the same length of conveyor pipe.

    Small concrete pump truck explosion tubing: Hydraulic tubing under pressure, due to various reasons, will also burst, if such a situation, do not panic, after extinguishing pressure relief to replace the tubing. However, if there is no oil pipe to replace, it is recommended that the concrete used be pumped back to the hopper to reduce the loss if oil permits.

    The working environment of small concrete pump truck is complex, so we must pay more attention to the maintenance after using, especially to the rotary bearing of small concrete pump truck.

    Let’s take a look at the specific operation: every day timely remove the gravel in the rotary bearing mechanism and check whether the rotary bearing bolt and the speed reducer fixed bolt are loosened and broken, found that the loosened and broken bolt must be replaced in time.

    Check every month, especially in autumn and winter when the temperature is low and the temperature difference is large. Check whether the shaft seal of the rotary reducer is damaged and open the oil outlet of the reducer to see if there is water entering the reducer to prevent frost cracking.

    Maintenance steps:

    Let the rotary reducer work for a period of time, the temperature rises by 30 degrees, unscrew the screw plug of the reducer, release the old oil, tighten the screw plug. Clean the gear reducer with cloth. Turn off the ventilation hood and oil level screw plug, and add about 4 litres of lubricant through the filling joint until the oil level hole has a clean oil outflow. Tighten oil level screw plug and cover ventilation hood
