The slow operation of the boom of the concrete pump truck will be accompanied by some abnormal phenomena, such as the controller can not accurately control the boom, and the boom operating device will jam. The above problems occur when the concrete pump boom is running, indicating that the boom is running slowly. Reasons for the slow operation of the boom:
1, the hydraulic oil is polluted, resulting in the abnormal operation of the hydraulic system, unable to provide power support for the boom, resulting in the slow operation of the boom.
2. When the boom works, the oil cylinder leaks, resulting in slow operation of the boom.
3, the boom oil supply is not smooth, the boom signal receiver failure, the boom is by accepting the remote control signal to execute the corresponding instructions, if the signal receiver can not operate will also lead to the slow operation of the boom. When analyzing the reasons for the slow operation of the boom, it is necessary to check the boom, and check the equipment that may cause the slow operation of the boom one by one, so that the cause of the failure can be quickly understood, so that measures can be taken to quickly repair the failure of the boom system.
Maintenance method
If the reason for the slow operation of the boom is that the hydraulic oil is polluted, the hydraulic oil should be replaced, and the reasons for the hydraulic oil pollution include the leakage of rainwater, the mixing of debris, etc., so the hydraulic oil should be sealed after the replacement to avoid the hydraulic oil being polluted again; If the reason for the slow operation of the boom is the leakage of the cylinder, it is necessary to repair the area causing the leakage of the cylinder. When the cylinder leaks, the appropriate maintenance plan should be selected according to the leakage situation. If the leakage scope is small, the cylinder can be repaired; If the leakage scope is too large, the cylinder must be replaced, because the cylinder leakage area is too large, prone to dangerous situations, only to replace the cylinder, not only to ensure the normal operation of the boom, but also to reduce the probability of risk occurrence.
