Three types of cement mixer maintenance and repair Due to the need for concrete mixing, compared to general engineering vehicles, its structure has its special features. The mixer has six additional systems: Therefore, in addition to the maintenance of automobile engines, chassis, and other parts, the concrete mixer truck must also be well maintained for concrete tanks (agitator drums), inlet and outlet port cleaning, and agitating maintenance drives. 1. After each delivery of concrete is completed, timely cleaning of the tank body and hopper can reduce the agglomeration phenomenon of the concrete on the three-piece sleeve, reduce the equipment downtime, and reduce the intensity of maintenance work.

2. Stagger the peak of production, timely perform partial repair welding on hoppers, eight-charging troughs, and unloading hoppers, and install tank openings to reduce leakage leakage caused by the equipment in the process of entering and discharging materials, and to ensure equipment integrity. Based on the maximum guarantee of the equipment tidy and improve the company's image.
3. In the off-season end of production, reasonably arrange the time to focus on cleaning the concrete inside the mixing tank body, check the wearing condition of the three-pieces, and replace the three-pieces with the heavily worn ones in time to ensure the continuous operation of the mixing truck in the next operation. . To increase equipment maintenance work is to reduce the intensity of equipment maintenance. Specifically, engineering machinery can be divided into the following three categories in terms of maintenance methods:
1, after the repair. The failure of the construction machinery to be repaired before use is referred to as post-mortem maintenance. When the loss of stop production is small, it is more economical to adopt this type of maintenance when only adjusting or replacing the wearing parts can eliminate the failure.
2, preventive maintenance. From a preventive point of view, preventive maintenance and repair before a failure occurs is called preventive maintenance. Preventive maintenance includes three aspects of routine maintenance, equipment inspection and preventive repair. Routine maintenance can prevent or postpone the deterioration of construction machinery, check or monitor the construction machinery periodically or irregularly, detect signs of failure and repair in time, and avoid sudden stoppage losses.
3, improve maintenance. This method is based on the results of fault recording and condition monitoring. While repairing the fault site, it improves the mechanical performance or local structure of the project to overcome the inherent deficiency of the construction machinery, improve the equipment performance, and reduce the failure, but it cannot compensate for the construction machinery. Invisible wear. Due to the special nature of the concrete industry and the shortage of company's equipment, in the current situation, our company's mixing stations often use this type of maintenance after repair. Judging from the effect of equipment operation, the attendance rate of agitated vehicles has been greatly ensured, and the cost of equipment maintenance has been greatly reduced. However, the maintenance of this equipment also has its limitations. In the early stages of equipment operation, the use of such equipment management methods is like killing chickens and eggs. Short-term costs are reduced at the cost of long-term maintenance costs. From another perspective, the concept of capital flow is considered in equipment assets. The initial small-scale maintenance of equipment or equipment maintenance costs a small amount of maintenance costs in the early period, in return for long-term stable output of the equipment; on the other hand, , Equipment with "disease" operation, the cost of investment in safety is unpredictable, and the maintenance of equipment at this cost is worth discussing. If only from the equipment point of view, taking preventive maintenance seems to be the most reasonable method, but the equipment in the production of relatively busy, to adopt such a method, it is worthwhile to think whether the cost increase it brings is worthwhile. Taking into account both the maintenance costs and the opportunity cost of the equipment is an aspect that must be considered in the management of concrete mixer trucks. Regular and regular monitoring of equipment operation status, feedback on equipment usage, timely and reasonable maintenance of the equipment, flexible use of three maintenance methods to find the balance of the equipment attendance rate and the lowest maintenance cost, maximize the company's profits.
