What factors should be considered when choosing concrete mixing station?

With the continuous development of science and technology and the wide application of new technology and technology, the types of concrete mixers are more complete, the structure is more complex and the performance is more superior. The requirements for the operation skills and equipment maintenance technology of concrete mixers are higher. Operators of machinery and equipment should have certain skills: fault diagnosis and maintenance, at the same time, they should have a high sense of responsibility and dedication. First of all, the main switch button of the pump in the cab should be turned on. The pump switch in the concrete mixing station behind the mixing truck will work. When using the water pump, do not turn off the car engine to facilitate the charging of dry batteries. When the pump turns it continuously, don't shut down the room and let the pump run idly. When the temperature is below 0 IC, after the water supply device is used, the water stored in the water tank, water pump and water pipe should be drained as far as possible to prevent freezing and fuse. If the pump is frozen, it can be filled with 40, 60 dejected water, until the motor shaft can be rotated by hand, then it can be used. Do not use water mixed with impurities such as sand, pebbles, or it will lead to pump wheezing. Do not pour more than 6090 hot water into the tank. The water tank should be equipped with a nozzle.

Flow chart of concrete conveyor's pleasant delivery to ready-mixed concrete. According to the requirement of the flow chart of transportation according to clothing: the longest time from discharging to discharging is 9 minutes, and the total speed of mixing drum is not more than 30 (k/min), because any ready-mixed concrete will enter the initial setting state around Jh without adding retarder. At this time, concrete pouring construction will affect the engineering quality of concrete, so screwing transportation is sometimes used to transport ready-mixed concrete. Inter-control is generally controlled within Wei. If it is considered that the original runner is not long enough and needs to be connected, the lengthened part can be supported by a support.

After discharging concrete, the interior of the mixing drum should be washed quickly. Otherwise, it will not only cause concrete condensation in the mixing drum, reduce the loading quality, but also cause accidents due to paralysis of machine readouts.

Firstly, in addition to the production of concrete mixing station is closely related to the site, the output of concrete mixing station with different supporting equipment used in different natural areas are also different, so customers in addition to the production of the first issue to consider is the site. The suitable type of concrete mixing station is selected according to the size of the site.

The second is to select the specifications and working dimensions of concrete mixer according to the equipment. The loading capacity of mixer truck should be matched with the discharge capacity of mixer, and improper matching will affect work efficiency.

The premise and foundation of equipment use is daily maintenance and maintenance. In the long-term and different environments of concrete mixer, the wear and tear of mechanical parts, the increase of clearance and the change of coordination directly affect the original balance of the equipment. The stability, reliability and efficiency of the equipment will be reduced to a considerable extent, which will even lead to the loss of its inherent basic performance and the normal operation of the mechanical equipment. In this way, the equipment will be overhauled or replaced, which undoubtedly increases the cost of enterprises and affects the rational allocation of enterprise resources. Therefore, it is necessary to establish a scientific and effective equipment management mechanism, strengthen the daily management of equipment, combine theory with practice, and scientifically and reasonably formulate equipment maintenance and maintenance plans.

1. Maintenance Principles and Requirements: Maintenance of concrete mixers focuses on cleaning, lubrication, inspection, tightening and anti-corrosion. Maintenance must follow the principle of "paying equal attention to maintenance and giving priority to prevention". Regular maintenance and compulsory maintenance should be carried out, and the relationship between use, maintenance and repair should be handled correctly. It is not allowed to use maintenance alone, but only to maintain. Maintenance machinery should be guaranteed quality. It should be carried out item by item according to the stipulated items and requirements. It should not be omitted or not insured. Maintenance items, maintenance quality and problems found in maintenance should be well documented and reported to our department for special work.

2. Implementation and supervision of maintenance operations: Mechanical maintenance adheres to the promotion of "cross" operation law with "cleaning, lubrication, adjustment, tightening and anticorrosion" as its main content, and carries out routine maintenance and regular maintenance system, strictly according to the cycle and inspection and maintenance items stipulated in the use instructions. Routine maintenance is to clean and inspect the key and vulnerable parts, coolant, lubricant, fuel quantity and instrument indication before and after the operation of machinery.
