1. Connect the emergency drive hose during loading and rely on the power of other mixer trucks. Drive the mixing drum to rotate and discharge the concrete. However, if the reducer fails at the same time, this method cannot be used. The specific operation steps are as follows:
(1)准备好一根紧急驱动软管,卸下接管和接头盖;
(1) Prepare an emergency drive hose and remove the connecting pipe and connector cover;
(2)故障车(被驱动车)的操作:将故障混凝土搅拌车的发动机熄火;将紧固螺母朝左旋松;再将旋钮朝右旋转,直到不能再旋为止;将高压软管从马达接头处卸下;
(2) Operation of the failed truck (driven truck): turn off the engine of the failed concrete mixer; loosen the fastening nut to the left; turn the knob to the right until it can no longer be screwed; remove the high-pressure hose from the motor connector;
(3)救援车(驱动车)的操作:将操作手柄至于空档位置;将发动机熄火;将高压软管从高压油管处卸下;将紧急驱动软管接到高压油管上;用紧急驱动软管上的接头盖将驱动车的高压软管盖起,以防漏油。启动救援车的发动机。将救援车的操作手柄拨至“出料”位置,使故障车内的混凝土排出。紧急驱动完毕后,使两车各自恢复原状。

(3) Operation of rescue vehicle (drive vehicle): set the operating handle to the neutral position; shut down the engine; remove the high-pressure hose from the high-pressure oil pipe; connect the emergency drive hose to the high-pressure oil pipe; cover the high-pressure hose of the drive vehicle with the connector cover on the emergency drive hose to prevent oil leakage. Start the engine of the rescue vehicle. Turn the operating handle of the rescue vehicle to "discharge" Position so that the concrete in the failed vehicle can be discharged. After the emergency drive, restore the two vehicles to their original state.
2.减速机损坏。如在工作中出现减速机突然损坏,首先需将搅拌筒内的混凝土排出,以防出现凝固现象;其次再更换减速机,也可联系生产厂家。
2. The reducer is damaged. If the reducer is suddenly damaged during operation, first discharge the concrete in the mixing drum to prevent solidification; Secondly, replace the reducer, or contact the manufacturer.
3.柱塞泵发生故障。非装载时换上新的柱塞泵,使拌筒恢复正常运转。
3. The plunger pump fails. When not loaded, replace with a new plunger pump to restore the normal operation of the mixing drum.
4.液压管接头处渗漏。将接头拆下,更换密封圈,重新拧紧即可。
4. Leakage at the hydraulic pipe joint. Remove the connector, replace the sealing ring and retighten it.
