In order to make better use of the spiral escort machine, strict management system should be formulated for the construction of the escort machine device to ensure that the escort machine will play the expected performance after it is put into use. The defects of screw conveyor have certain regularity, which can be divided into early, middle and late stages. The manufacturer of powder conveyor thinks that these laws provide the basis for the analysis of the causes of defects and maintenance methods.

?? 1. Early defects. In the early stage, that is, the commissioning and operation stage of the walkie talkie device, there are many hidden troubles in the walkie talkie during this process. If it is not handled in time, it will lead to a series of trouble risks in the later stage. Generally speaking, the level of early defects is different, the length of time is not the same. For example, there are some defects in the design and manufacture, poor performance, parts processing and material selection.

?? 2. However, there will be new problems in the operation of the escort machine, such as: the vulnerable parts are not replaced in time, because some parts are close to their service life and cycle in the middle of operation; The replaced parts are not matched or are still in the running in period. Some of them have assembly errors, which easily lead to problems of the escort machine. There are many factors causing mid-term problems, which are related to personnel operation and the performance of the escort machine, so the maintenance is difficult.

?? 3. Late problems. In the later period of operation, the chemical consumption escort machine has entered a period of frequent faults due to the wear, fatigue, aging and corrosion of various parts. For example, after months of operation and repeated maintenance, the escort machine has changed more parts, and its output can not reach the original design level. With the passage of time, the failure rate of the spiral escort machine in the later period has increased from time to time, so the enterprise must stop for maintenance and replace new parts in time.
