[Scene definition] How to monitor screw wear and tear using exterior, gap and product data is to start from the actual production scene of the plant and not just the diameter or price of the screw. It is recommended that the filling content, corrosive media, temperature and operating hours be first collated, and that baselines be established for each of the three phases of start-up, stable production and refuelling. The aim of this step is to establish comparable old programme benchmarks so that subsequent screw changes can be supported by data.

The easiest to ignore is the rate of wear and tear, the growth of the gap and the sudden failure. The plant should break down the daily production into class beats, time available and model exchange losses, and divide needs such as appearance, size, strength and smell into necessary items and optimizations. Vendors can make retroactive trade-offs between interoperability, earmarking and cost when there are clear values for product weight, daily production, customer quality caps and allowed stop times.

The main line of the case [design focus] is the selection of materials, thermal treatment and surface layer based on the wear and tear machine. In geometric and material programmes, the inner and worn state of the cylinders should be incorporated into the co-ordinated gap to avoid new screws being dragged by old cylinders; and the screw diameter, a valid itinerary and a single simulator mass should be calibrated to prevent long stops. The final solution would also need to be compatible with the wear and tear of the cylinder, the drive, the physical velocity and the current cleaning process, and would not cover up co-operation or process problems with a single high-level material.

The new [comparison-valid] program proposes a minimum of 48 hours of continuous operation, with a 100-mode extraction for each stabilization phase, and records the screw-back load, back pressure stability and daily production. The test should be conducted immediately after the test, with acoustics, friction marks and metal powders being examined, in a timely manner, to identify co-exposed risks, with stabilization points established at medium velocity and medium back pressure, and a gradual extension of the process window. If only the first one is checked, it is easy to miss the risks associated with heat drifting, material stoppage, reversal loop return and prolonged wear and tear.

When the [stabilized production] spiral is shaped, the temperature-preservation time for cold-starting and the permission to twist should be set to avoid cold-temperature forced storage, and records should be numbered with a single asset associated with drawings, repair, up and down. The time of storage, back pressure, screw velocity, noise and mass of the product shall be recorded in a uniform manner in the shift. When the above indicators change at the same time, the mechanical gaps and the state of the raw materials should be checked before the process is adjusted to avoid the use of parameters to compensate for hardware degradation.

The cost table [comprehensive cost] could not simply be a spiral price, and three life-cycle scenarios should be set, optimistic, benchmarked and conservative, to prevent a single hypothesis from magnifying the return on investment and to analyse single-unit energy consumption in conjunction with storage time to avoid looking only at the total of the meter and ignoring output differences. It is recommended that the cost per 10,000 eligible items be exported simultaneously, the cost per 1,000 operating hours and the estimated number of return months. When new programmes reduce waste, refuelling or sudden shutdowns, higher initial inputs are often offset during production.

The [Closed Ring Management] will eventually include drawing numbers, screwdriver materials, heat treatment, critical dimensions, portable tubes, process windows and acceptance data in the curriculum vitae cards. It is recommended that stratums by batch of raw materials be used to prevent the miscalculation of formula fluctuations as a matter of equipment, and that a system of metallic heterogeneity separation and magnetic insulation be established, and that pry damage be examined after the anomaly. When there is a significant change in the feedstock formulation, retrospective ratio, product structure or target node, the applicable boundary of “how to monitor the grinding of the screw with the outer diameter, gap and product data” should be reassessed, rather than defaulting that the old conclusion is permanent.
