Concrete pump truck failure causes and emergency treatment

  Concrete pump trucks are now used in many construction sites, supporting infrastructure construction. In addition to the high reliability of the pump truck, it is necessary to do a good job in normal times to check and maintain the pump truck, as well as the need to master the pump truck failure of the emergency treatment plan, otherwise it will lead to tragedy.

  1. Failure to keep up with normal maintenance results in failure of the concrete pump truck

  Swing cylinder and s swing valve swing handle off the main reason is because of the nut off the fastening. But the nut falls off does not happen overnight, this also explains this pump car in the ordinary time maintenance and overhauls above some lack. If checked frequently, such failures generally do not occur.

  2. Lack of experience in emergency treatment causes the concrete in the pipe to set

  The failure of concrete pump truck can not be pumped and can not be repaired in a short time, should immediately empty the pipe in the concrete, otherwise it will cause the pipe scrap. While the concrete still has mobility, the hopper behind the bent pipe disassembled, and then the boom vertical by the gravity of the concrete itself from the conveying pipe discharge. The concrete in the tube, however, needs to be disassembled and discharged manually. If the above-mentioned method can not let the concrete in the pipe automatically discharge, can start from the hopper back bend, to the direction of the pump boom to remove the pipe, as far as possible to reduce the clogging length of the conveying pipe, reduce the loss and later workload. But be careful to remove the pipe when the arm should be flat, to prevent because of the gravity of the pipe out of the concrete injury. With its own high-pressure water gun or on-site water pipe washing conveying cylinder and s pendulum inside the concrete, to prevent the concrete solidification. Because s pendulum valve can not work, in the flushing of another cylinder, you can use a pry bar in the hopper to move the s pendulum valve again, and then flush with a water gun.
