To evaluate whether a concrete mixing plant is good, this needs to be considered in many aspects. Perhaps from a unilateral point of view, for the boss, it is good equipment that can ensure production efficiency and bring economic benefits, and for operators, it is good equipment that is convenient to operate, low maintenance rate and easy to maintain. In my opinion, it is very important to ensure the stable operation of the equipment, and the key is to be people-oriented. Based on my own experience and experience, the author makes a general analysis of the problems existing in concrete equipment, hoping to be useful to everyone.
When the concrete equipment leaves the factory, it is easy to use and can not be fully defined as a good product, the short-term operation is stable and easy to do, the reason behind it is very simple, in a single environment, its variables are limited, it is easy to deal with, if the time is extended, 5 years, 10 years, 20 years, there are multiple uncertain customers to use, the raw materials are changing, the machinery will wear and corrode, then, the variables will grow in geometric progression, in the case of this large variable, the stability of the product will undergo a severe test.
Perhaps, the assumption of a small probability event becomes a high probability event under certain conditions, and the effective means to solve the stability problem is long-term careful and in-depth thinking, repeated trial and error, and complete the accumulation.
We divide it into 3 stages, design, manufacturing, and use. Design and manufacturing are entirely in the hands of the maker, and use is the interaction between the manufacturer and the customer.
It is impossible for the manufacturer to have complete control over the situation, and the worst-case scenario is that the customer is unreasonable and uses the product in a destructive way, which is rareAt the other end of the spectrum, it is rare for customers to be obedient to the manufacturer and think that their employees are not good.
In most cases, if the manufacturer's design concept is people-oriented, well-made, and service-oriented, the customer will consciously cooperate and communicate with the manufacturer as a partnerOn the contrary, the customer abuses the equipment and breaks the can. Once the customer is dissatisfied with the product, the first war, the relationship war has become the only means of sales, to some extent, stability is everything about the product.
This issue is the most easily overlooked, and almost no one mentions it, and the general concern is that it meets national standards, industry standards. However, the truth is that all performance, including stability, is based on the authenticity of the data, and the 'truth' can never be obtained, but can be approached slowly, and moreover, the truth seeking is an ascetic errand that usually no one likes.
The mystery of nature's rules of the game is also here, this is the only way to do a good job in products for a long time, the great enterprises in the world today (manufacturing), if you do not consider their marketing methods (human factors), from the core of the business (science and technology foundation), there are no exceptions, their power happens to be their deep understanding and implementation of natural laws, that is, truth-seeking.
As far as the industry is concerned, how to get real data will always be a problem, and the reality at the moment is that the better the equipment, the more real the data, and vice versa.
Without exception, there is a sentence in the product advertisements of all peers that "high measurement accuracy", in fact, this sentence is for laymen.
The insider's statement should be like this, what are the determinants of measurement accuracy?
How can these factors be controlled?
The distribution range of accuracy is **?
How does the spirit of precision and proportioning work?
How can the long-term stability of accuracy be achieved?
There is a very complex scientific spirit behind the seemingly simple questions, so to speak, there is no standard answer to these questions, which is the fundamental reason why products can be improved.
If something is perfect, its death is near.
The vast majority of customers care more about this metric than all other performance, but this problem is the simplest, the least technical, and the biggest benefit is that customers can make money faster.
Efficiency involves several aspects, the level of process design and manufacturing of the equipment, the degree of coordination of the control system, the adaptability of raw materials, and the level of customer scheduling (this must be supported by a network management system or the so-called "ERP").
But then again, if the process design of the manufacturing side is flawed, there is limited room for other steps to actually improve, and in fact, most manufacturers do not pass this hurdle.
This question is about the customer's feelings, in fact, most of the customer evaluations of the mixing plant are based on this feeling, which has its reasonable side and its unreasonable side. This is the basic point of human nature, always want to use the simplest actions to achieve the best results, the good side is to make the product more in line with the actual use requirements, the bad side is to abuse for the sake of simplicity. For the manufacturer, this is difficult to grasp, that is to say, operability is not only a scientific problem, but also an artistic problem, and the balance requires a humanistic level.
In fact, there are far more problems that actually exist than these five, and I have only listed them in part.
Finally, to make an unpleasant gap comparison, first of all, take the design level of Japanese peer equipment 30-50 years ago as a reference standard.
The domestic design level can be roughly divided into two levels, one is close to 0 points, and the other is below 0 points.
The design level close to 0 points is such that the equipment can ensure basic stability and produce concrete, that is, the plagiarism of the surface phenomenon is successful. It can be guessed that those with a score of less than 0 can't even plagiarize the superficial phenomenon, there is no mechanic on the side, and the equipment can break down at any time.
