the operator should accumulate a wealth of experience

Secondly, the operator should accumulate a wealth of experience, able to anticipate most of the mechanical failure, early settlement, eliminate hidden dangers. After failure, should be able to accurately determine js1500 used concrete mixer mercedes benz immediately removed, ensure the normal use of machinery. To do this, press operator in addition to the mechanical maintenance of order in a timely manner, but also do the following:           (1) The operator should regularly inspect, careful observation, carefully check the site for regular exercise. Check the connections loose, lubrication is good, action is flexible, with or without abnormal wear, identify problems and timely treatment;           (2) dynamic change in the mix station, use the ears listen, carefully think about and figure out every sound, if there is not a normal voice. To identify the cause and properly handle;           (3) To identify smells good. Such as high oil temperature, the material temperature gauge, circuit, electrical shorting and burn, overheating caused by abnormal friction, electrical appliances, circuit overload serious from heat, etc., will make different smells, different smells, part of the fault may be predicted.     In short, the operator should pay attention to check Yan concept of color, through a variety of feeling, with different instruments, clarify each abnormal changes, careful analysis, to identify the reasons, identify risks. better js litter concrete mixer machine Because mixing station complex structure, a wide range of spare parts, related to electricity, gas control system, asphalt supply systems, combustion systems, metering systems, dust removal systems. To be proficient in the various parts of a manipulator in the short term, to accurately determine and rectify all faults, it is very difficult. Therefore, to want to be a good operator, should be carefully observed, diligent in thinking, conscientiously sum up, continue to accumulate experience.      Also in addition to proficiency equipment operator, it should also have knowledge of product quality control. That is, the temperature of the asphalt mix, aggregate ratio, grading and other somewhat familiar with, and can be cooked refining technology to mix judge promptly analyze and solve problems mix.        (1) the mix temperature control: the temperature of the mixture is one of the standard mix of conformity assessment, the temperature is too high or too low are waste, it can not be used. Therefore, how to control the temperature is one of the operator should have the basic skills. Factors affecting the temperature of the mixture have fuel quality. If the poor quality of fuel, low calorific value, concrete mixer truck spare part of js1500 combustion is not sufficient, it will cause instability stone heating, low temperature, post-combustion residue remains in the mix, seriously affecting the quality of the mix. If the fuel viscosity is too large, the impurity content of more, larger water content. Will result in ignition difficulties, pipe blockage, the temperature is difficult to control; water content of raw materials is another factor affecting the temperature. The water content of raw materials large and uneven in the production process, the heating temperature is difficult to control the stone; additional combustion system technical condition, the fuel supply pump pressure, as well as the size of the fuel injection quantity, it is related to the temperature of the mixture. Wear combustion system, leakage, blockage fault so that all parts can not maintain the original performance, resulting in lower system pressure, fuel supply instability, poor atomization burning effect, seriously affecting the stirring temperature. Therefore, the experienced operator should be able to accurately determine the quality of fuel, work wet and dry raw materials, as well as combustion system. Identify problems dual-horizontal-shaft forced concrete mixer and take appropriate measures. Although mixing devices have automatic temperature control, but due to the subtraction from the detected temperature flame temperature control is a process, and therefore to control the temperature of a lag. To ensure that no waste stirring temperature mixing station, operator should carefully observed by the rate of change in temperature, change in temperature results predicted in advance, and manually add and subtract flame or decrease feed rate to control the temperature changes, so changes in results does not exceed the specified range, thereby reducing or eliminating waste.
